Tips To Keep Your Commercial Refrigeration System Running at Top Efficiency

commercial refrigeration tips
Refrigeration doesn’t get applause. It doesn’t plate food, serve cocktails, or post cool content online. But behind the scenes? It’s the engine keeping everything from your walk-in to your lowboys quietly humming. And when it slips—even a little—it doesn’t just cost energy; it bleeds money. Efficiency nosedives, food quality takes a hit, and surprise repairs stomp all over your budget.

From the contractor’s side of the wrench, we’ve seen it all: iced-over coils, melted compressors, units choked with grime. Almost every big-ticket failure started with something small, preventable, and overlooked. So here’s the real advice—the kind facilities managers and kitchen operators actually need, but rarely hear.


1. Clear those coils (before they choke your wallet)
We get it—no one wants to bend behind a cooler with a brush. But condenser coils, when coated in grease, dust, and whatever floats through your kitchen air, start to suffocate. Airflow drops, temperatures climb, compressors overwork… and your energy bill gets fatter than your brisket.

We’ve walked into kitchens where the coil looked like it had been dredged from a swamp. That buildup forces the system to run longer and harder, driving up wear. Cleaning coils monthly—not yearly—is cheap and crucial. Especially in high-volume kitchens, it makes a real difference.


2. Check door gaskets like you check your phone

Worn, cracked, or loose gaskets are silent assassins. A tiny tear can suck in warm, humid air all night long. That moisture fogs up evaporators, invites frost buildup, and throws internal temps out of whack. And if it’s a reach-in that staff open 300 times a day? That leak’s costing you real money.

A tight seal saves energy. It also keeps your system from cycling more than necessary. We recommend managers add gasket inspection to their weekly walkthroughs—press your fingers around the door edge, check for warps, listen for that satisfying whoosh when it closes.


3. Don’t block vents and fans (your airflow matters)

It seems harmless—stacking product in front of the fan or packing the fridge to the ceiling. But that airflow inside your unit isn’t just there for fun. It’s precisely calibrated. Blocked vents restrict circulation, which creates hot spots and makes the system compensate. Over time, it strains the blower motor and throws off defrost cycles.

Train your team: leave room around the fan. Don’t overstock. Label shelves if you have to. A few inches of clearance could mean the difference between a healthy system and a meltdown at lunch rush.


4. Set it and leave it: Thermostats aren’t volume knobs

We’ve seen staff crank thermostats down “just to be sure” things stay cold. It doesn’t work that way. Dropping the setting doesn’t cool faster—it just forces the system to run longer. That shortcut will trash your compressor faster than a rat in a bread box.

Thermostats are precise tools. They should be calibrated by a tech annually and left alone. If product temps are off, call for service. Don’t play guessing games with food safety.


5. Log everything: Temps, cycles, complaints

You can’t manage what you don’t track. And yet, too many places have zero records when we ask how the unit’s been performing. A simple log—daily temps, any noise complaints, frost sightings—can help catch problems before they snowball. It gives your tech real info to work from, which means quicker, cheaper fixes.

Digital logs? Even better. They help you spot trends. And if you ever need to show documentation during an inspection or insurance claim? You’ll be glad you kept them.


6. Schedule preventive maintenance—not just repairs

Don’t treat your refrigeration system like a rental car. Wait until it fails, and you’ll always be paying more. Emergency calls are expensive, parts are pricier under pressure, and downtime is devastating for foodservice.

Smart facility managers know: two PM visits a year pays off. A tech can spot refrigerant issues, tighten electrical connections, clean drain pans, test pressures—basically stop breakdowns before they ruin your Friday night service.


7. Watch for early warning signs—because they’re always there

Funny noises, water pooling on the floor, a unit running louder than normal—these aren’t quirks, they’re cries for help. Compressor short-cycling? That’s your system saying fix me. Odors, frost patterns, uneven cooling—all of them are red flags we see right before big problems.

Train your staff to report weird behavior. The sooner a tech sees it, the cheaper and easier the fix will be.


Day & Nite All Service: Contractors Who Care About Cold

We’ve been in kitchens before the sun comes up and after the last dish goes out. We’ve crawled behind freezers in the middle of the July heat wave and changed evaporator fans in walk-ins so cold it feels like punishment. That’s what we do. But our best work? It’s done before the system breaks.

If you’re ready to stop rolling the dice with your refrigeration system, give us a call. We’ll build a custom maintenance schedule that makes sense for your space, your volume, your budget. And we’ll do it with the kind of experience that prevents drama… not just fixes it.

Avoid Common Emergency Repairs To Commercial Kitchen Equipment

ChatGPT Image May 1, 2025, 10 02 15 PM

Running a commercial kitchen is chaos on a clock—every second counts, every plate matters. One machine sputters, and the whole rhythm collapses. Day & Nite / All Service has seen this play out in every possible flavor, from steakhouses in Queens to school cafeterias in Newark. The kicker? Most of these emergencies were ticking time bombs that could’ve been defused weeks—or even months—earlier.

The Hidden Cost of Emergency Service Calls

Here’s the truth: emergency repairs are the most expensive way to deal with equipment. Not just in dollars and cents—though those invoices can sting—but in downtime, spoiled food, lost customers, and stressed-out staff who can’t do their job. A failed fryer at 6 PM on a Saturday? That’s not a repair call; that’s a business threat.

It’s not rare for commercial kitchens to blow $1,500+ on a same-day refrigeration fix. Add another $800 for rush parts, $2,000 in food waste, and another $1,000 in lost revenue. That’s a four-grand “oops” because a condenser wasn’t cleaned.

Most Common Emergency Repairs (and Why They Hurt)

Techs at Day & Nite see the same five or six culprits over and over. They’re like bad guests—showing up uninvited and always when it’s least convenient.

  • Refrigeration units that stop cooling: Clogged coils, faulty thermostats, worn gaskets… doesn’t matter which—it leads to spoiled product and potentially a failed health inspection. Walk-ins, undercounters, prep tables. All at risk.

  • Flat-top grills and ranges that won’t light: Often due to dirty burners, broken igniters, or a pilot line leak. And if your kitchen’s turning out 100+ meals an hour, every second that grill’s cold is money melting.

  • Commercial fryers with temperature control failure: They either stop heating or worse, overheat. That means dangerous conditions, ruined oil, and inconsistent food. Boil-overs are kitchen nightmares—literally fiery.

  • Dishwashers leaking or not sanitizing properly: This one’s sneaky. You might not notice until customers complain about grime on plates. But when inspectors notice, it’s a red tag, maybe even a shutdown.

  • Ice machines flooding or dispensing moldy cubes. Regular cleaning and sanitization would’ve prevented both. But emergency calls? Usually after water damage’s already done or customers post photos.

  • Combi ovens that suddenly error-out: These are precise machines. But one missed calibration or skipped descaling and suddenly you’re staring at error codes you can’t decipher. With no steam, there’s no service.

Why It’s All Preventable (Seriously)

Here’s where things get frustrating: 70% of those service calls could’ve been prevented with a 30-minute maintenance check. Day & Nite crews often open up units and find easy fixes that would’ve cost pennies if caught early—cracked belts, dirty sensors, blown fuses. Nothing exotic.

Preventive maintenance keeps equipment tuned, safe, and efficient. It’s like flossing for your kitchen. Not flashy, but it saves you a fortune in root canals later.

A quarterly PM plan means:

  • Technicians clean and calibrate ovens so they don’t cook unevenly

  • Refrigeration units are tested for leaks, and coils get brushed out before efficiency tanks

  • Gaskets and seals are checked, so cold air stays where it should

  • Fryers are inspected for oil quality, thermostat precision, and basket wear

  • Dishmachines get descaled, sanitized, and spray arms unclogged

More Up-Time Means More Profit

The math isn’t hard. If your kitchen runs 12 hours a day, 6 days a week, that’s over 3,700 hours a year. Even losing 50 of those hours to equipment breakdowns cuts deep. That’s 50 hours of lost orders, wasted payroll, unhappy guests, and stressed managers putting out fires (literally, sometimes).

But when your gear hums along like it should? That’s stability. Predictability. Profit. You know your ovens hold temp, your walk-in is ice-cold, and your ice machine won’t turn your bar floor into a slip-and-slide. You get to focus on food and service—not scrambling for emergency repairs.

Day & Nite / All Service Makes It Easy

They’re not just a repair crew. They’re a strategy partner. Their PM plans are tailored—by equipment, usage level, and even season. Got a high-volume QSR or an upscale bistro? Different needs, different checklists.

And the best part: Their team tracks trends. If a certain fryer model has a known issue, they flag it before it fails. That means fewer breakdowns and more uptime across the board.

Don’t Wait for Something to Break

Emergency repairs don’t just break your budget. They break your rhythm, your confidence, your ability to serve food fast and fresh. Skip the scramble.

How To Get An “A” On Your Restaurant’s Health Inspection: The Inside Track From Refrigeration Pros

restaurant health grade

Getting an “A” on a health inspection used to be tough. Now? It’s a full-on gladiator match. Across the U.S., nearly every state and city runs some version of a kitchen inspection program. Whether it’s the Florida Department of Business and Professional Regulation, the Los Angeles County Department of Public Health, or the titans of scrutiny over at NYC’s Department of Health and Mental Hygiene, the goal is simple: protect diners. But how they do it, and how intense the standards have gotten? That’s where it gets tricky.

New York City, for example, doesn’t mess around. Their inspectors walk in clipboard-first and eyes sharp. Every unnoticed crumb or degree off in your refrigeration unit’s temp could send your letter grade from A to B—or worse. And it’s not just New York. Places like Chicago, Boston, San Francisco—they’re all doubling down. The days of skating by on charm and good intentions are long gone. A shiny dining room and stellar service won’t save you if your walk-in fridge is hitting 45°F instead of 41°F. That’s four little degrees… and one big citation.

Why Health Inspections Are Getting Tougher

Over the past decade, public pressure and food safety transparency have cranked up the heat on health departments. Diners want to know what’s happening behind the kitchen door. And with sites like Yelp now showing health grades, a single misstep can turn into a PR nightmare.

Plus, departments themselves have started integrating tech: digital scoring, real-time inspection uploads, automated flagging for repeat violations. Combine that with the aftershocks of the pandemic—like staffing shortages, supply chain issues, and general burnout—and it’s no wonder restaurants are struggling more than ever to hit that elusive “A.”

Temperature Violations: The Silent Grade Killer

Ask any seasoned restaurant owner what tanked their grade, and you’ll hear one phrase again and again: “The fridge.”

Health codes across the country are clear. Cold-holding units must keep food at or below 41°F. That’s not a suggestion. That’s law. And it’s not just the main cooler—prep tables, undercounter fridges, dessert stations—every single one is fair game. If your mozzarella balls are sitting at 43°F when the inspector sticks their thermometer in? That’s points off.

Same with hot-holding. Food that’s meant to stay hot must be at 135°F or above. Drop below that during a busy brunch rush? Points.

But here’s the kicker: most of these temperature violations come from equipment failure, not human error. Motors overheat. Thermostats die. Door gaskets wear down and let in warm air. And unless your line cooks are secretly part-time mechanics, you won’t even notice until it’s too late.

Where Day & Nite All Service Comes In

This is where Day & Nite All Service makes all the difference. They’re not just repair techs. They’re the quiet force that stands between you and a B-grade warning sign on your front window.

With decades in the industry, they know exactly how and why equipment fails—and how to stop it from happening. Their technicians don’t just fix what’s broken. They identify early warning signs, fine-tune systems before inspections, and help restaurants stay one step ahead of even the pickiest inspector.

You know those moments when a walk-in compressor starts making a weird sound at 10:47 p.m. on a Saturday? Yeah—they’re on that. Or when your reach-in is reading 42.5°F, but the thermometer says 39? They’ll catch that calibration issue before the health department does.

It’s Not Just About Avoiding a Bad Grade—It’s About Reputation and Revenue

One bad health grade doesn’t just sting. It sticks. Customers see it. Online reviewers magnify it. Delivery apps might pause your listings. And competitors? They don’t mind swooping in to take your lunch rush crowd.

Then there’s the financial hit. A bad inspection can lead to forced closures, mandatory reinspections, and steep fines—not to mention spoiled food and canceled reservations.

But the flip side? An “A” rating builds trust. It tells your diners: “We care. We’re clean. You’re safe here.” That’s why restaurants that partner with Day & Nite All Service don’t just stay open—they thrive. They avoid emergencies, extend the life of their equipment, and breeze through inspections with confidence instead of dread.

What You Can Do Right Now

If you’re serious about that “A,” don’t wait until inspection day to scramble. Build a maintenance schedule. Keep logs of internal food temperatures. Train your staff on proper storage, labeling, and cleaning routines.

And most importantly—get professionals involved. Schedule a kitchen inspection pre-check with Day & Nite All Service. Let their experts walk through your space, spot vulnerabilities, and fine-tune everything from refrigeration to ventilation.

Because in the restaurant world, an “A” isn’t just a letter. It’s a badge of honor. And with Day & Nite on your side, it’s a whole lot easier to earn.

Commercial Kitchen Cleaning Tips That Actually Work — And Help Your Equipment Last Longer

commercial kitchen cleaning

Nobody walks into a kitchen and marvels at the fryer gunk or the layers of grease on the exhaust hood. Clean kitchens don’t just look good—they perform better. The secret? Smart, consistent cleaning routines that keep your commercial kitchen equipment alive longer and working like it’s fresh out the box.

This isn’t about wiping surfaces with a rag and calling it a day. It’s about precision. A dirty commercial kitchen doesn’t just risk health codes or inspections—it chews through equipment life faster than a poorly trained line cook during dinner rush.

Why This Matters: The Hidden Cost of Neglect

Commercial kitchen gear is expensive. A single malfunctioning range, fryer, or walk-in fridge can bring operations to a screeching halt. Worst-case? A failed inspection, food spoilage, or worse—a fire. According to the National Fire Protection Association, nearly 60% of restaurant fires start in the kitchen, often due to built-up grease in hoods, vents, and cooking appliances. That’s avoidable.

And then there’s efficiency. A clogged condenser coil or dirty burner means the unit works harder—eats more energy, and breaks faster. So what’s the fix? Clean smarter. Clean often. And know where to look.


1. Deep Clean Daily, But Know Your Targets

Daily cleaning shouldn’t just be a checklist—it should be strategic.

  • Wipe down flat tops and griddles after every shift; use the right scraper so you’re not gouging the metal.

  • Empty and wipe the deep fryer; filter the oil, and clean the baskets.

  • Steam tables? Drain and descale.

  • Under-counter fridges? Clean gaskets and wipe interiors—yes, every day.

It’s not obsessive—it’s insurance.


2. Weekly = Time for the Grit Work

Every week, hit the stuff that doesn’t look dirty but is.

  • Clean condenser coils on refrigeration units with a coil brush or vacuum—this one step adds years to a unit’s life.

  • Degrease exhaust hoods and filters—if you’re not pulling those filters and soaking them, you’re risking fire and airflow issues.

  • Sharpen blades on slicers and clean between every hidden seam.

  • Check and clean the drip trays on ice machines and drink dispensers.

Weekly jobs are the backbone of equipment preservation. You miss a week, and it shows.


3. Don’t Forget the Vents, Floors, and Walls

Grease splatter loves corners. Vents suck up nastiness. Floors trap particles that grind underfoot and turn your kitchen into a skating rink.

  • Power scrub the floors weekly. Use degreaser—not just soap and water.

  • Clean walls and ceiling vents that pull in airborne oil. You’d be surprised how fast buildup happens, especially above fryers and ovens.

  • Use a long-handle brush to dust and degrease air return ducts and filters.


4. Watch the Water and Steam Equipment

Dishwashers, steamers, and combi ovens build up limescale like it’s their job.

  • Use a proper descaler and clean the interiors monthly.

  • Drain boilers if applicable.

  • Check for leaks around seals—standing water is a mold and rust party waiting to happen.

  • Don’t use hard water without filtration; it’s a silent equipment killer.


5. Schedule Professional Deep Cleans and Servicing

You can’t do it all with elbow grease. At least twice a year, bring in certified pros to do:

  • Full exhaust system cleanings (including ductwork to the roof)

  • Gas line and burner inspections

  • Refrigeration system diagnostics

  • Combustion checks on ovens and steam equipment

And don’t skimp on filter replacements—air, grease, water, you name it.


6. Keep a Cleaning Log—And Stick to It

This is boring but brilliant. A log keeps people accountable, shows inspectors you mean business, and makes it crystal clear what’s been done—and what’s overdue.

Make it digital. Use a whiteboard. Clipboards on fridges. Just keep it visible, and make sure someone’s in charge of enforcement.


7. Use the Right Cleaning Tools for the Job

This isn’t a Windex world. Wrong tools scratch stainless steel, ruin seals, or worse, void warranties. Have a cleaning kit with:

  • Degreaser (food-safe, non-toxic)

  • Stainless steel cleaner

  • Coil brush

  • Scrapers

  • Steam cleaner for grout and corners

  • Food-grade descaler

Train your team how to use each—don’t assume they’ll figure it out.


8. Respect the Manufacturer’s Manual

Yeah, it’s dusty. But that little booklet? It tells you exactly how to clean each unit without wrecking it. It also tells you the service intervals, and what voids your warranty. Read it. Then follow it. Then tape it to the wall if you have to.


A Clean Kitchen Is a Working Kitchen

Equipment doesn’t fail because it’s old. It fails because it’s abused, ignored, and smothered in burnt cheese and fryer grease.

Clean gear runs better. It cooks evenly. It chills faster. It breaks down less. And most importantly, it keeps your kitchen moving when it counts—during the crunch, the rush, and the 15-ticket printer panic.

So if you want to protect your equipment investment, stay ahead of health codes, and sleep better knowing tomorrow’s service will go smooth—clean smarter. Clean consistently. And teach your crew to treat that oven or freezer like it’s worth its weight in truffles.

Because honestly, it is.
