For Nevada restaurants, grocery stores, and food service businesses, keeping your walk-in coolers and freezers sealed tight isn’t just about temperature control it’s about saving money. A worn or damaged door gasket might seem minor, but it can cause your refrigeration system to work overtime, driving up energy bills and reducing the lifespan of your equipment.
At Buffo’s Refrigeration, we often find that one of the most common and costly problems in commercial refrigeration systems is poor door sealing. Here’s how bad seals quietly increase your refrigeration costs and what you can do to prevent it
How Poor Seals Waste Energy
A walk-in cooler or freezer relies on a tight door seal to keep cold air in and warm air out. When the door gasket is cracked, loose, or dirty, cold air escapes, and warm air enters every time the door closes.
That temperature exchange forces the compressor and fans to work harder to restore proper cooling. Over time, this adds up to significant energy waste. Even a small air leak can increase power consumption by 10–25%, depending on the system and environment.
In Nevada’s humid summers and freezing winters, fluctuating air temperatures put even more strain on refrigeration systems with poor seals.
Food Safety and Spoilage Risks
Energy loss isn’t the only problem caused by faulty seals. Warm air that leaks into the cooler introduces moisture and heat, which can cause:
- Inconsistent temperatures across storage zones
- Premature food spoilage
- Bacterial growth in perishable items
If your refrigeration unit struggles to maintain a stable temperature, it could even lead to food safety code violations—a costly and preventable issue.
Frost and Ice Build-Up
When warm, moist air enters a freezer through a damaged seal, it condenses and freezes inside the unit. This leads to heavy frost accumulation on walls, floors, and evaporator coils.
That frost buildup reduces airflow and cooling efficiency, making your system work even harder. Over time, this cycle of ice formation and melting increases wear on compressors and evaporator fans, eventually leading to expensive repairs or premature system failure.
Increased Maintenance and Repair Costs
A poor seal might seem harmless at first, but constant overworking of the refrigeration system takes a toll. You might notice:
- Shorter compressor life
- More frequent service calls
- Higher energy bills month after month
Replacing a worn gasket is inexpensive compared to the cost of a compressor replacement or spoiled inventory. Regular inspections can help you catch gasket wear early and avoid unnecessary expenses.
How to Spot a Poor Seal
You can perform a few quick checks to see if your door seals are in good shape:
- Look for cracks, tears, or gaps in the gasket material
- Close the door on a dollar bill—if you can easily pull it out, the seal isn’t tight enough
- Watch for condensation or frost forming near the door frame
- Check if the door closes automatically and latches securely
If you notice any of these signs, it’s time to schedule a professional inspection.
Preventing Seal-Related Energy Loss
To keep your walk-in coolers and freezers operating efficiently:
- Clean door gaskets regularly with mild soap and water to prevent grime buildup
- Inspect seals monthly for damage or looseness
- Replace worn gaskets as soon as possible
- Schedule preventative maintenance to ensure door alignment and hinges stay in good condition
At Buffo’s Refrigeration, we include gasket inspections as part of our commercial refrigeration maintenance programs, helping Nevada businesses prevent small leaks from becoming costly energy drains.
FAQs About Refrigeration Seals
How often should gaskets be replaced?
Most commercial cooler and freezer gaskets should be replaced every 1–2 years, depending on usage and environment.
Can I replace a gasket myself?
It’s possible, but professional installation ensures a perfect fit and proper seal. Our technicians carry manufacturer-approved replacements for all major brands.
What’s the best way to extend gasket life?
Keep the door clean, avoid slamming it, and ensure proper alignment to reduce unnecessary stress on the gasket.
