What it costs, Daly City

KryoFridge is the clear first choice for freezer trailer rentals in Daly City

We size the trailer to what you are actually storing, not to the biggest unit on the yard. Tell us how many pallets or cases you need to hold and how many times a day the door opens. Those two numbers decide it. A small 6x8 behind a Mission Street kitchen loses less cold on a busy lunch than a big box half full, and it fits the narrow lots common across Daly City. A grocery back room staging holiday stock near Serramonte Center might need the 16 ft utility trailer instead, and we will say so plainly. We have more than 30 years in the equipment rental business, we own every trailer we rent, and we run one of the largest refrigerated and freezer trailer fleets in the West. Call now or request a quote, and you will get the right size on the first try.

The right size, stated honestly

We ask about your load and your door traffic before we name a unit. A smaller trailer that opens fifty times a day often holds temperature better than a large one that is mostly empty.

Freezer or cooler in one unit

Set the trailer anywhere from about 50 degrees down to minus 10. Switch the setting later if your needs change during the rental.

A fleet we own

Every trailer on the road belongs to us. You talk to the company that delivers and services the unit, not a broker in another state.

Power plan before delivery

You get a clear answer up front: a dedicated 120-volt, 20-amp circuit within 100 feet, or our generator. Nobody hunts for an outlet on delivery day.

Paperwork agencies accept

We are SAM.gov registered for public agency work, licensed and insured, and backed by an A+ BBB rated network with a 99.9 percent incident-free record. Schools, hospitals, and chains can approve the rental without a long review.

Walk-ins fail at bad hours. Our emergency line is staffed around the clock, and dispatch starts on the first call.

Take a look, Daly City

Meet the unit that handles most of our jobs near Daly City

Daly City rarely gets hot, with a year-round average near 57 degrees, so the real test here is the door opening all day in damp, foggy air, and our units pull back to your set point fast after each rush.

The flagship 16' Utility cold chain trailer, white for rental in Daly City
16' insulated boxRear double doors + side utility third door-10°F to +50°F range120V/20A or generatorTandem axle

When the stakes are real, the 16' Utility is what we send. Sixteen feet of insulated, NSF-approved box on a tandem axle, running one precise digital set-point that covers deep freeze at -10°F all the way up to a 50°F cooler. The rear double doors handle pallet work off a dock, and the side utility door means a cook can pull one tray without letting the heat in.

The trailer that shows up is one of ours, prepped in our own shop, fueled and pre-cooled before it leaves the yard. It takes a dedicated 120V, 20-amp circuit or the generator we provide, and it will hold that set-point through a triple-digit stretch without drama.

Mobile cold storage on wheels from Westlake to the Cow Palace

We deliver across all of Daly City, from the ocean bluffs above Mussel Rock to the Bayshore side near Geneva Avenue. Trucks come in on I-280, Highway 1, and Skyline Boulevard, then work the hills street by street. We also serve customers in all 50 states, so a chain with stores beyond the Peninsula can use one number for all of them.

Neighborhoods and towns we cover include Westlake, Serramonte, Top of the Hill, Bayshore, Crocker, St. Francis Heights, Southern Hills, Hillside, Mission Street, John Daly Boulevard, Geneva Avenue, Skyline Boulevard, Lake Merced, Daly City BART area, Mussel Rock, San Bruno Mountain, Colma, Brisbane, Pacifica, South San Francisco, San Bruno, Millbrae.

The greater Daly City communities we deliver to

Each community around Daly City has its own venues, its own events, and its own cold storage headaches. We work all of them.

Westlake

Most of Westlake was built by Henry Doelger starting in the late 1940s, and its streets climb and curve toward the ocean. Restaurant and grocery calls here often come with a lot on a hill, so we bring leveling gear and plan the drop spot ahead of time.

Serramonte

The area around Serramonte Center has the city's biggest concentration of grocery and restaurant space. Deliveries here are quick off I-280 and Highway 1, and most units go right to a receiving door.

Top of the Hill

Where Mission Street meets John Daly Boulevard, small restaurants and bakeries share tight blocks and limited parking. A 6x8 unit is usually the right fit, placed behind the building and out of the sidewalk.

Bayshore and the Cow Palace

Bayshore joined Daly City in 1963 and sits closest to the Cow Palace on Geneva Avenue. Event weeks here bring requests for vendor cold storage and kitchen overflow, often booked weeks ahead.

Crocker, St. Francis Heights, and Southern Hills

These quieter neighborhoods hold corner markets, churches, and family restaurants. Calls from this side of town are often outage backup during winter storms and short rentals for a big food order.

Pacifica and Colma

Pacifica gets even more direct coastal weather than Daly City, and Colma sits just to the south. We cover restaurants, markets, and event kitchens in both towns on the same routes.

One call sizes the trailer, sets the delivery window, and locks your quote for Daly City. Call now, or send the quick quote request and we will call you.

More jobs our portable cold storage rentals handle in Daly City

About 101,000 people live in Daly City's 7.6 square miles, and most of the food they buy moves through a handful of busy stores, restaurants, and kitchens. There is not much spare room anywhere. These are the three kinds of jobs we plan for most, and what a rented trailer changes for each one.

🍽 Grand National Rodeo week at the Cow Palace

The rodeo has run at the Cow Palace since 1941, and the 2026 show lands October 9 and 10. Concession teams stage meat, dairy, and drinks for big crowds, and a cooler trailer behind the vendor area holds the backup stock.

School kitchens still have to feed students when a walk-in quits mid semester. A small trailer at the loading door keeps milk and frozen items safe until the repair is signed off.

A white KryoFridge portable refrigeration unit supporting Food bank distribution days in Daly City

🤝 Food bank distribution days

Second Harvest of Silicon Valley describes its service area as running from Daly City to Gilroy. Pantries and partner sites use extra cold room to hold frozen protein and produce for big distribution days.

What ties these together is the clock. Nobody budgets a freezer trailer into next quarter. They reach for one the hour a compressor quits, or the evening before a party when the stack of rented ice chests suddenly looks laughably undersized. Since our units sit staged around Daly City instead of a couple counties down the freeway, "can I get it today" is an ordinary ask here, not a stretch.

Adding up the cost of lost product for Daly City-area clients

Ask us anything, Daly City

Add it up the way an owner in Daly City has to. One restaurant walk-in routinely sits on a small fortune in proteins, dairy, and prepped product. Scale that to a grocery rack or a warehouse freezer bay and the exposure balloons. Now knock the power or the compressor out on a triple-digit afternoon, and that whole inventory is in jeopardy inside a few hours. Then stack on the sales you lose while the line sits dark and the wages you burn paying staff to triage what can still be saved.

Hold a pre-staged trailer up against that risk and it reads like cheap insurance, a fixed, predictable expense parked in front of a loss with no ceiling. That is exactly why the businesses that got stung once tape our number by the phone. There is never a second scramble, because the next time they dial before the product has a chance to warm. Owning every trailer ourselves means we can scale the answer to fit. A single compact box suits a corner cafe. A clustered setup covers a warehouse floor. Either one is booked with a single call.

Grocery backup with walk-in freezer trailer rentals near Serramonte and Westlake

Serramonte Center has anchored retail here since 1968, and the blocks around it hold some of the busiest food shopping in northern San Mateo County. Sprouts Farmers Market sits across the street. A Safeway works nearby, and Trader Joe's draws steady traffic at Westlake Shopping Center. Stores this busy fill their back rooms fast. When a walk-in fails or a holiday truck shows up early, the product has nowhere to go.

A cold storage trailer at the dock gives that product a place to wait. We usually set the unit close to the receiving door so a pallet jack can roll straight in. Frozen goods go in one trailer at zero or below. If the store also needs chilled room for milk and produce, a second unit runs in the mid 30s. Same model, two settings, one layout for your crew to learn.

Walk-in freezer trailer parked at a grocery receiving door on a foggy morning

Thanksgiving and Christmas are just the start of the busy weeks in Daly City. With 57 percent of residents Asian American and a third of the city Filipino American, Lunar New Year and the long Filipino Christmas season bring their own spikes in frozen seafood, pork, and party trays. Markets that serve those customers often need extra freezer room for weeks, not days. A trailer out back lets a store buy ahead and keep the main walk-in clear for daily stock.

Parking is the hard part. Many store lots here are shared, sloped, or boxed in by other tenants. We ask for a photo of the spot, check the grade, and plan where the refrigeration end will vent so it is not blowing into a walkway. Chains with stores down south can book the same setup through our Santa Clarita cold storage trailer rentals crew, so the process feels the same in both places.

Three portable freezer trailer sizes for Daly City kitchens and stockrooms

Every KryoFridge unit can run as a freezer or as a cooler. You pick a set point anywhere from about 50 degrees down to minus 10, and the trailer holds it. A market can keep ice cream rock hard in one unit and set a second one in the mid 30s for produce and dairy.

We carry three footprints. The 6x8 Freezer Trailer suits a single restaurant or a small corner store. The 6x12 Freezer Trailer takes a bigger kitchen or a catering crew with a full weekend of product. Our 16-Foot Utility Freezer Trailer is the one for grocery pallets and real volume. Each has a lockable door and room for shelves.

Power is simple to plan. You provide a dedicated 120-volt, 20-amp circuit within 100 feet, or we bring a generator. Our driver levels the trailer, starts the refrigeration, and waits until it is pulling down before leaving. When you are done, one call gets it picked up.

Temporary cold storage rentals for power outages and product recalls

Daly City is not in a high fire risk zone, and that is good news for anyone worried about planned wildfire shutoffs. The bigger threats here are winter storms and earthquakes. The city itself warns that heavy rain can bring local flooding and hillside slides, and its history includes two damaging earthquakes, the 1906 event centered near Mussel Rock and a 5.3 in 1957 that hit Westlake hard.

When the power drops, the clock starts. Federal food safety guidance says a closed refrigerator keeps food safe for about four hours, and a full freezer holds for about 48. A grocery store or hospital kitchen cannot count on the lights coming back inside that window. A generator-powered trailer moves the most valuable stock out of danger and keeps it there while PG&E crews work.

Generator-powered refrigerated trailer behind a store during a winter storm outage

Recalls are the other surge. When a supplier pulls a product, stores have to get it off the shelves fast and keep it apart from good stock until the vendor picks it up or the lot is cleared. That can mean dozens of cases of frozen or chilled food sitting in the way for days. A separate trailer set to the right temperature keeps recalled product cold, locked, and out of the main cooler, which is exactly what a health inspector wants to see.

We plan these calls around speed. Our emergency line is answered around the clock, and a trailer can be on your lot the same day in most of California. Chains with stores in Arizona can reach our Tempe mobile refrigeration rentals team the same way. For recall holds, tell us how many cases are coming off the shelf, and we will size the unit to fit them with room left to sort.

Mobile refrigeration rentals for commissary kitchens and small food makers

There are no big factories inside Daly City. Most of the food made here comes out of commissary kitchens, caterers, bread and pastry shops, and small producers who turn out pastries and frozen meals by the tray. The larger plants and distribution warehouses sit a few minutes south in South San Francisco. Small makers still run into the same problem as the big ones. Their freezers fill up before the order is done.

A portable freezer trailer gives a small kitchen a place to stage finished product. A maker filling a big holiday order can freeze trays in batches and move them into the trailer overnight. The kitchen freezer stays open for the next day of production. When the order ships, the trailer goes back to us or stays for the next run.

Cold room also helps before cooking. Caterers and commissaries often take large deliveries of meat or seafood at once to get a better price. Holding that raw product at zero in a locked trailer keeps it separate from ready-to-eat food, which matters to an inspector. We can set one unit for raw product and a second as a cooler for prepped items waiting to go out.

Space around these kitchens is tight. Many sit in older commercial buildings with a single alley door or a few spaces out front. We look at the loading path before we pick the size. It is the same thinking our Tulare freezer trailer rentals crew brings to food plants in the Central Valley, just scaled to a small Peninsula kitchen with one door and a steep driveway.

What we hold a cold storage trailer at, load by load near Daly City

"Cold" is not one number. Different product stays safe inside different temperature windows, which is the entire reason a precise digital set-point matters, and in the middle of a heat wave in Daly City, a load that slips out of its window is a load you write off. Use the chart below as the reference our customers lean on when they size a rental.

ProductTarget holding bandTrailer mode
Ice cream and frozen desserts-10°F to 0°FDeep freeze
Frozen proteins, seafood, prepared meals0°F or belowFreezer
Fresh meat and poultry (short hold)28°F to 32°FRefrigerated
Dairy, deli, packaged produce34°F to 38°FRefrigerated
Beverages, florals, catering trays38°F to 45°FRefrigerated

One figure matters more than everything in that chart, and it is not listed there: 40°F. Food-safety guidance treats the band between 40°F and 140°F as the zone where bacteria thrive, and the clock on perishable product starts ticking the moment it crosses 40 on the way up. Roughly four cumulative hours above that line and most refrigerated inventory is no longer safe to serve. Picture that countdown running on a 100-degree afternoon in Daly City with the walk-in dark, and the urgency of a quick trailer drop stops being abstract.

Tell us the single coldest item you are holding when you call, and we dial the trailer to that. One unit carries a straight freezer load with no fuss. But when your list mixes deep-freeze desserts with fresh-cold produce for the same remodel or event, we will usually point you toward a split setup or a second box so neither side of the load has to settle for the wrong temperature.

Electrical and access for a refrigerated trailer around greater Daly City

Powering one of our trailers is refreshingly simple, and there are precisely two ways to do it. Either you have a dedicated 120-volt, 20-amp circuit reachable within roughly 100 feet of the parking spot, or we bring a generator. What the units will not accept is standard 208 to 240V building service, so a quick question about your outlet before dispatch heads off any surprise on delivery day.

  • Dedicated outlet on hand? Most Daly City kitchens and markets already have the right one, so we plug straight in and the unit begins pulling the temperature down.
  • Open lot or event field? A generator keeps the trailer running anywhere, whether that is an event lawn or a warehouse yard.
  • Worried about a shutoff? A unit on a generator keeps your cold chain alive when a storm or a utility outage takes the surrounding grid down.

On placement, all the unit really asks for is a fairly flat patch with enough room for the delivery truck to maneuver it in and set it straight, plus either a power source in reach or space for a generator. We lock down the exact drop point before dispatch, and our drivers know the Daly City layout cold, so the delivery is one clean trip instead of a guessing game on the property.

A typical refrigeration trailer delivery for Daly City warehouses, start to finish

Fair warning, Daly City

Neighborhood market with a failed walk-in freezer

When a market loses its walk-in freezer, we start with the product count on the phone and send the smallest trailer that fits it. The driver backs it up to the side or rear door, levels it on the grade, and starts the refrigeration so it is pulling down while the crew stacks cases. Power comes from a free dedicated circuit or from our generator. The trailer stays until the repair tech signs off.

Grocery store holding recalled product

When a recall notice lands, we set a separate trailer next to the receiving door at the temperature the product needs. Staff move the pulled cases in, label them, and lock the door. Good stock never mixes with held stock. The trailer stays until the vendor collects the product or the store gets the all clear.

Caterer staging a large holiday order

When a caterer takes on a big December order, we place a 6x12 unit at the kitchen door and set it to freeze. Finished trays go in by batch each night, and the kitchen freezer stays free for the next day of cooking. On pickup day, the van loads straight from the trailer.

Set up for fog and salt air. Daly City sits on the coast where damp, salty air hangs around most mornings. We keep units maintained for it, check door seals before every delivery, and point the refrigeration end away from the wind when the lot allows.

Renting the trailer is the simplest thing on your site in Daly City

On a bad day, booking should be the part that does not add stress. Four steps, an upfront number, and a single person who owns the whole thing.

Step 1 · Describe the load

Tell us whether it is freezer or fridge product, a ballpark volume, and your rough window. That is enough for us to call the right size.

Step 2 · We finalize size, power and spot

We pair you with a unit, confirm whether you have a dedicated circuit or need a generator, and pin the exact drop point so the truck makes one trip.

Step 3 · Drop-off, placement and cold-down

We arrive on your schedule, about 45 minutes for a true emergency, set the trailer, energize it, and let it drive down to your number.

Step 4 · Use it, we stay on call

It holds the set-point for your entire term while our line stays live the whole way through. Wrap up, and we swing back for the pickup.

San Mateo County food rules for refrigerated cold storage rentals

Food safety basics

The California Retail Food Code covers every food business in Daly City, and San Mateo County Environmental Health handles the permits and inspections. The number most inspectors watch is 41 degrees or below for cold food, and 0 degrees or below for frozen product. A rented trailer set well under those lines gives you a clean reading and some room for a busy door.

If a trailer will serve as long-term extra storage for a permitted kitchen or market, call the county office before it arrives and ask what they want to see. Short emergency use during a repair is common. Longer use raises questions about placement, pest control, and how food moves between the trailer and the building. We send unit spec sheets so you have them ready. Crews with sites in southern Utah can ask our St. George walk-in freezer trailers team how things work on that side.

Events follow a separate path. Anyone selling or giving away food at an event in San Mateo County needs a temporary event health permit, filed at least 14 calendar days ahead. Food and equipment must sit at least six inches off the ground, and raw meat stays apart from ready-to-eat food. You also need a City of Daly City business license for commercial activity, including short event work, so check that too.

How our rental freezer trailers hold up in a health-code visit in Daly City

  • NSF-approved interior surfaces built for direct food contact.
  • A digital controller that puts the set-point in plain view for the inspector.
  • Proper drainage and a sealed, food-safe insulated box.
  • Licensed and insured on every unit we put on the road.

One caveat we always state plainly: we supply the food-safe, temperature-holding hardware itself, but we are not a temperature-logging or alarm-monitoring service. If your program requires continuous written records, line that vendor up on your own.

Sizing your cold storage trailer: 6x8, 6x12 or 6x16 near Daly City

Our signature 16 foot Utility series leads the fleet. It is the trailer we send on most jobs, and crews like it for the side utility access door. We build three footprints in all, so a single kitchen holding overflow stock has a fit and so does a distribution floor in a disaster. Every unit is dual purpose by design: one adjustable system swings between freezer and refrigerator on a digital set point. Each trailer runs on a dedicated circuit or on a generator.

6x12Grocers, caterers, mid-size eventsDeep-freeze capable
6x8Tight lots, small kitchens, short overflow-10°F to 50°F

All three sizes switch between freezer and cooler mode, so the choice comes down to footprint and how much product you need to hold.

6x8 footprint, the compact unit for a few pallets near Daly City

It's the unit to grab when square footage is the whole problem. It slips into the pinched service yards and cramped back-of-house corners that a larger box cannot even swing into. One cafe or small-market walk-in goes down, and this is almost always enough cold to cover it, plus the simplest unit to set in a small space.

6x12 trailer, the everyday pick for grocers and caterers near Daly City

Deep-freeze rated, and far and away the size people ask for most. It lands right in the middle: roomy enough for a multi-day catering job or a restaurant that needs true walk-in-equivalent room while the kitchen is torn up. Roomy enough that nobody is playing Tetris with shelves, yet still small enough to set in most commercial back lots without a site survey.

6x16, the heavy-duty pick near Daly City

Our biggest footprint, paired with a heavy-duty reefer plant engineered to keep deep-freeze locked in even when the ambient air is merciless. Reach for it when a warehouse bay drops, when a large festival needs an anchor, or when a relief operation is carrying its own cold chain.

Not sure which size fits? Most customers land on the 16 foot Utility, and we will tell you honestly if a smaller footprint covers your job. Tell us roughly what you are storing and for how long, and we will spec it for you.

Deeper questions about refrigerated trailer rentals in Daly City

The questions that surface once the basics are settled. Tap any topic to open it.

What suits a caterer: a refrigerated trailer, a walk-in or a reefer truck

The pop-up walk-in cooler. Cheap to rent and easy to set up, but it chills, it does not freeze, and it draws every watt it needs from your building while depending on a calm ambient temperature around it. The second your building loses power, your cooler loses it too.

The refrigerated box truck. Designed to haul product on the interstate, not to sit in a lot and babysit it. Parked, it burns fuel all day, broadcasts compressor noise across a storefront or an event lawn, and pins down a tractor plus a driver you probably do not need.

The freezer trailer we deliver. Built from the ground up to be dropped on a pad and to defend a temperature for as long as the job runs. It freezes deep, carries NSF approval, locks, stays quiet near guests, and lives on nothing more than one dedicated circuit or a generator.

Food-contact surfaces, drainage and your health department

Even a rented box has to satisfy the county environmental health office that licenses and inspects every food facility. Show an inspector a unit that cannot document its temperature or was not built for food contact, and they have the authority to halt service immediately.

That is a bar each of our trailers clears: NSF-approved throughout, food-safe interior surfaces, proper drainage, and a digital controller that puts the set-point in plain view. We supply the food-safe, temperature-holding hardware itself, but we are not a temperature-logging or alarm-monitoring service.

When one box is not enough for a big event

For a typical kitchen or market, one box does the job. Distribution floors, big fairs, and full-scale disaster response routinely need more, and because the fleet is ours, we can cluster several units and bring them online in waves as the work expands. Match the cold capacity to the operation rather than make the operation squeeze itself into one box.

Rental terms for a build-out: emergency drop or contract

The clock is yours to set. Some jobs are a handful of days for an emergency or a single event. Others stretch across weeks or months for a remodel or a seasonal swell, and a few become standing contracts for businesses that want capacity parked on standby. Name your window and you will get a clean quote, no penalty for an honest "not sure yet."

The rent-or-build question for a seasonal peak

Building permanent cold storage is a capital project in every sense: you hire a refrigeration contractor, schedule the electrical, pull a building permit, and wait weeks before a single pallet goes inside. A rental turns that equation on its head. You bring in precisely the cold you need, for precisely the stretch you need it, and the trailer is holding temperature within days, not months, with the commitment ending the moment your need is over.

How a trailer holds deep-freeze in a heat wave

Three engineered elements carry the load. Thick insulated panels and tightly gasketed doors lock the sun outside and the cold inside. A self-contained reefer condensing system specified with surplus capacity keeps stripping heat out of the box even when the air outside is brutal. And a digital thermostat locks onto your chosen number and cycles the compressor to hold the line. Run those three together and a trailer baking on open asphalt behaves like one tucked in a cool warehouse. That is also why power is the first thing we ask about: the design delivers its safety margin only on steady, uninterrupted power.

Further Daly City-area reviews, in their own words

"We had a recall come through and needed the product out of the main cooler fast. They set up a separate locked unit the same day. Clean and simple."

Lisa K. · receiving lead, grocery store

"Our lot is on a hill, and I was sure it would not work. The driver leveled it in about twenty minutes."

Victor A. · kitchen manager, family restaurant

"When our cafeteria cooler went down mid semester, the trailer kept milk and lunch items safe until the repair was finished. The paperwork was easy to get approved."

Michelle S. · food service director, school campus

"We needed backup cold storage during a compressor replacement. They ran it on their generator because we could not spare a circuit, and the temperature log stayed flat the whole time."

Dennis L. · facilities supervisor, hospital kitchen

"Three of us split one cooler trailer for the festival weekend. Backup stock stayed cold, and nobody had to run to the store mid afternoon."

Marisol R. · food vendor, street festival

"Lunar New Year volume is huge for us. The extra freezer space let us buy ahead instead of turning away orders."

Ken W. · manager, Asian market

"We held frozen chicken and produce for a big distribution day. Setup was quick and they explained the display so our volunteers could check temps."

Teresa P. · pantry coordinator, food distribution site

"Rodeo week used to mean ice chests everywhere. One trailer behind the stands did the job better."

Jun C. · concessions lead, arena event weeks

"We use them at more than one location now. They always ask about power first, which saves us a headache every time."

Angela V. · operations lead, restaurant group

What Daly City accounts ask before a walk-in freezer trailer rental

Do I need two trailers to keep ice cream frozen and produce cold at my Daly City store?

Usually, yes. Each trailer holds one set point at a time, somewhere between about 50 degrees and minus 10. Most stores that need both run one unit as a freezer and one as a cooler. Both are the same model, so your crew learns one layout. If you only need both for a short stretch, you can also switch a single trailer between modes as your stock changes.

Will you keep a trailer at our store for a few months while a new walk-in is ordered and installed?

Yes. Many rentals run a week or two, but long terms are common when a new walk-in has to be built, delivered, and inspected. We set monthly terms for those jobs and can extend them if the install slips. If your needs change partway through, we can swap to a smaller or larger footprint.

Can a rented freezer trailer get back down to zero after a busy morning of door openings?

Yes, and fast, as long as the door is not propped open. The refrigeration unit is sized to pull the box back down after normal loading. The best habit is to plan trips in and out, keep the door shut between them, and avoid loading warm product in large batches. In Daly City's mild, foggy weather, recovery is quicker than in hot inland towns.

Is a trailer safe overnight in a shared shopping center lot in Daly City?

Every unit has a lockable door, and you can add your own padlock. We try to park it close to your building, in view of cameras and lights. We also chock and level the trailer so it cannot roll on a slope. If you lease your space, a quick call to the property manager before delivery avoids any surprise about where it can sit.

Where do I call if the refrigeration unit stops working in the middle of the night?

Call our 24/7 line. A real person answers, and we start by walking through the display and the power source with you, since a tripped breaker or an unplugged cord is the most common cause. If the unit needs hands-on work, we dispatch a tech or bring a replacement trailer and help you move product across. Keep the door closed while you wait, and the box will hold its temperature for a good while.

What will a San Mateo County health inspector want to see in a rented cold storage trailer?

Mostly the same things as in your walk-in. Food should be at 41 degrees or below if chilled and 0 or below if frozen, stored off the floor, and covered. Raw meat stays apart from ready-to-eat items. A thermometer and a simple temperature log help a lot. For longer rentals, call the county first and ask how they want the trailer handled.

When does a portable freezer trailer rental cost more, and when does it cost less?

A few things move the number. Bigger trailers cost more than smaller ones, and longer rentals usually cost less per day. Adding our generator adds to the total. A middle of the night emergency drop takes more to run than a planned delivery next week. Call us with your size, dates, and power situation, and we will give you a clear quote.

How do I power a mobile freezer on a lot with no free outlet?

You have two choices. The first is a dedicated 120-volt, 20-amp circuit within 100 feet of the trailer, with nothing else on it. The second is a generator we bring and set up. Many older Daly City buildings have panels that are already full, so the generator is often the easier path. We sort out which one fits before we deliver.

Does the fog and salt air in Daly City affect a rented refrigeration unit?

Damp coastal air is hard on older refrigeration equipment over time. Our trailers are maintained between rentals, and we check seals and the refrigeration unit before each delivery. On site, we point the unit away from the strongest wind when the lot allows it.

Are hilly streets in Daly City a problem for delivery?

Not usually, but they change how we plan. We ask for a photo of the spot and the approach, then check the slope and the turning room. Our drivers carry leveling gear for lots on a hill. If a spot is too steep or too tight, we will suggest a better one nearby before the truck leaves.

Should recalled product go in a separate trailer from good stock?

It is the cleanest way to handle it. A separate, locked trailer keeps recalled food cold and fully apart from what you are still selling. Staff cannot grab the wrong case by mistake, and an inspector can see the held product at a glance. We size the unit to the number of cases being pulled.

How to prep a sloped or tight Daly City lot for a portable freezer trailer

Most of the trouble we see on delivery day starts with a spot that looked fine in someone's head. In Daly City, the usual problem is not the size of the lot. It is the slope, the turn, or the car parked where the truck needs to swing. A few minutes of prep saves a lot of backing and waiting.

Start with the ground. The trailer needs firm footing, and asphalt or concrete is best. A gentle grade is fine because our drivers carry leveling gear. A steep driveway in Westlake or on the hills above Mission Street is a different story. If you are not sure how steep your spot is, send us a photo taken from the street and one from the spot itself. We can tell a lot from two pictures.

Planning a food booth at a Cow Palace show or the Top of the Hill Festival

Big events here put a lot of food in one place for a short time. A rodeo weekend can bring thousands of people past your booth in a few hours. The food has to stay cold before it gets cooked or served. Ice chests work for a small booth. They fall apart fast when you are feeding a crowd.

Start with the permit. San Mateo County requires a temporary event health permit for anyone selling or giving away food at an event, and the application is due at least 14 calendar days ahead. Most event organizers coordinate the vendor paperwork, but each booth still has to meet the rules. Get your application in early so a late permit does not decide your weekend for you.

When to book cold storage trailer rentals around Daly City's busy food seasons

Emergency calls come at any hour, and we answer them. Planned rentals are different. A little lead time gets you the exact size you want on the day you want it. A few stretches of the year fill our schedule faster than people expect.

Lunar New Year comes first on the calendar. Markets and restaurants that serve the city's large Asian American community stock up on frozen seafood, pork, and dumplings for weeks ahead of the holiday. Booking a trailer two to three weeks before the date usually does the job. Stores that wait until the week of often find their main freezer already full.

Mobile freezer trailer, refrigerated truck, or pallet space: choosing backup cold storage on the Peninsula

When a walk-in fails or a busy season needs more room, most businesses look at three or four choices. Each one has a place. The right pick depends on how much product you have, how long you need the space, and how often your crew needs to reach it.

Dry ice and coolers are the quickest fix for a tiny problem. They work for a few hours or a small amount of product. Past that, they get hard to manage. Dry ice needs careful handling and good airflow, and coolers do not hold a steady temperature. Most kitchens move past them within a day.
