Alright, friends, let’s have a real talk about something that can turn a bustling downtown kitchen into a popsicle palace overnight: frozen coils. It’s the bane of every restaurant owner’s existence when the mercury drops. One day, your walk-in is humming along perfectly; the next, it’s struggling like a car trying to start on a sub-zero morning. We’ve seen it all, and trust us, a little prevention goes a long, long way.
We’re going to walk through why this happens and, more importantly, how you can stop it before it starts. Because let’s be honest, the last thing you want to do during a dinner rush is explain to the head chef why the backup freezer is now the primary freezer. IMO, a few simple habits can save you a world of stress—and a hefty repair bill.
Why Your Commercial Fridge Thinks It’s an Ice Sculpture
So, why do coils freeze up? It’s not because your equipment has a sudden appreciation for winter art. It almost always comes down to airflow and temperature balance.
The Usual Suspects: A Quick List
Think of your commercial refrigeration system as needing to breathe. When it can’t, it panics and freezes. Here are the most common culprits we see at Pavel Refrigerant Services when we get calls for commercial refrigeration repair in the dead of winter:
- Dirty Coils: This is the big one. Dust, grease, and grime act like a thick winter coat on the coils. The refrigerant inside can’t shed its heat properly, causing the evaporator coils to get too cold and freeze the moisture in the air. It’s a classic case of being too well-insulated for its own good.
- Failing Door Seals: Those gaskets around your walk in cooler door might seem insignificant, but they are your first line of defense. When they wear out, warm, moist air from your kitchen sneaks in. That moisture meets the cold coils and—you guessed it—freezes solid. It’s a slow but steady invasion.
- Low Refrigerant Charge: This is a more serious issue. If your system is low on refrigerant, it can cause the pressure to drop, leading to a lower temperature at the evaporator coil than it’s designed for. This is a job for professionals, like our team at Pavel Refrigerant Services, because it requires specialized tools and expertise to diagnose and fix safely.
- Faulty Defrost System: Your unit is supposed to have a built-in defense mechanism! The defrost cycle (using heaters, or by reversing the refrigerant flow) periodically melts any minor frost buildup. When the defrost thermostat, heater, or timer fails, that frost just keeps building up into a solid block of ice.
Ever wondered why this seems to happen more in winter? It’s because the air inside your building is often much drier, but the temperature differential between the cold outside and the warm kitchen can put extra strain on the system. It’s a perfect storm for commercial freezer repair emergencies.
Your Winter Prevention Playbook: Stop the Freeze Before It Starts
Okay, enough with the problem. Let’s get to the solutions. This isn’t rocket science; it’s about consistent, simple maintenance. Think of it as a workout routine for your walk in refrigerator repair avoidance strategy.
The Weekly & Monthly Checklist You’ll Actually Use
We’re all busy, so we’ll keep this practical. Here’s a straightforward plan to keep your system running smoothly.
- Visual Inspection is Key: Make it a habit to take a quick peek at the coils inside your cooler or freezer once a week. Are you starting to see a dust bunny convention? Is there a thin layer of frost where there shouldn’t be? Catching it early is everything.
- Clean Those Coils: We can’t stress this enough. How often depends on your environment. A busy bakery might need monthly cleaning, while a less dusty storage area might be okay quarterly. Turn off the unit, use a soft brush and a commercial coil cleaner, and gently remove all that gunk. FYI, this single task prevents a massive percentage of service calls.
- Test the Door Seals: The “dollar bill test” is a classic for a reason. Shut a dollar bill in the door. If you can pull it out with little to no resistance, it’s time to replace the gasket. It’s a cheap fix compared to the cost of the energy wasted and the strain on your compressor.
- Listen to Your Unit: Your refrigeration system has a normal “sound.” Get familiar with it. If you start hearing new noises—hissing, grinding, or the compressor short-cycling (turning on and off rapidly)—it’s crying for help. Don’t ignore it.
What’s the one thing we always recommend? Professional commercial refrigeration maintenance. It’s like taking your car in for an oil change. A certified technician from a trusted company like ours can spot the small issues—a slightly worn fan belt, the beginnings of a refrigerant leak—that you might miss. This proactive approach is almost always cheaper than the reactive commercial fridge repair that follows a total breakdown.
When to Call the Pros (And Why You Shouldn’t Wait)
We get it. Nobody wants to make that call. You’re thinking about the price of the service and the disruption. But waiting is a gamble you’ll likely lose.
You should pick up the phone for your nearest commercial refrigeration service if:
- You see ice buildup that’s more than a quarter-inch thick on the coils.
- The unit is running constantly but not reaching its set temperature.
- You notice water pooling around the unit (a sign of a completely frozen coil that’s now melting and overflowing the drain pan).
- There’s any indication of a refrigerant leak (oily residue on pipes, a hissing sound).

The Real Cost: Reactive Repair vs. Proactive Maintenance
Let’s break down the numbers in a way that makes the choice obvious. It’s not just about the immediate invoice; it’s about the total impact on your business.
| Scenario | Proactive Maintenance | Reactive Emergency Repair |
|---|---|---|
| Typical Cost | Predictable, scheduled service fee. | Higher emergency rates, plus parts. |
| Business Impact | Scheduled at your convenience, minimal disruption. | Unexpected downtime during peak hours. |
| Component Stress | Extends the life of your entire system. | Puts extreme strain on the compressor, risking a total failure. |
| Food Safety | Consistent temperatures ensure food quality and safety. | Risk of massive spoilage and loss of inventory. |
| Your Stress Level | Low. You’re in control. | Through the roof. You’re in crisis mode. |
See the difference? A little investment in commercial refrigeration maintenance saves you money, time, and your sanity in the long run. Trying to find the closest “commercial refrigeration repair near me” at 7 PM on a Friday is a scenario we wouldn’t wish on our worst enemy.
Your Frozen Coils Questions, Answered
We hear these all the time. Let’s clear a few things up.
1. Can I just turn the unit off and let the ice melt myself?
You can, and it might work for a very minor frost buildup. But it’s a temporary fix that doesn’t address the root cause. If the coil is a solid block of ice, manually defrosting it can take hours, during which your product is at risk. A professional will use safe, rapid defrosting methods and, crucially, diagnose why it happened so it doesn’t become a weekly ritual.
2. How much should a standard commercial refrigeration service call cost?
The cost can vary based on the issue, time of day, and required parts. A simple maintenance visit has a standard rate. An emergency industrial refrigeration repair at 3 AM on a holiday will understandably be more. The best policy? Ask for upfront pricing. At Pavel Refrigerant Services, we believe in transparent quotes before we start any work, so there are no surprises.
3. Do you service areas outside of Montgomery County, like Washington or Arlington?
Absolutely. While we’re based in Montgomery County and love serving our nearby communities like Wheaton and Silver Spring, our team frequently handles commercial walk in cooler repair calls in Washington and Arlington. Don’t hesitate to call us if you’re in the broader DMV area—we’ll let you know if we can be your fastest solution.
Don’t Let Winter Win
Look, winter is tough enough without your equipment joining the enemy. A frozen coil might seem like a small thing, but it’s a symptom of a larger issue that can lead to catastrophic (and expensive) compressor failure.
The key takeaway? Be proactive. A consistent maintenance routine is your best defense. And when you suspect something is beyond a simple cleaning, call in the cavalry. Whether you’re dealing with a finicky reach-in or need a major walk in cooler repair, having a trusted partner like Pavel Refrigerant Services on speed dial is just good business.
So, let’s keep those coils clean, those doors sealed, and those chefs happy. Your bottom line will thank you.
