When it comes to commercial refrigeration, there’s no shortage of advice — but not all of it is accurate. In fact, some common misconceptions can lead to higher energy bills, premature equipment wear, and unexpected downtime.
At Buffo’s Refrigeration, we’ve worked with grocery stores, restaurants, and food service operators across Nevada, and we’ve seen firsthand how a few persistent refrigeration myths end up costing businesses time and money. Let’s separate fact from fiction.
Myth #1: “If It’s Still Cooling, It Doesn’t Need Maintenance.”
This is one of the most expensive refrigeration myths around. Just because your cooler or freezer is still running doesn’t mean it’s running efficiently. Over time, dirt, dust, and wear can reduce performance and drive up energy use — even if temperatures seem fine.
The truth: Regular preventative maintenance keeps systems operating at peak efficiency, reduces energy costs, and helps avoid costly emergency repairs. Buffo’s Refrigeration recommends at least biannual maintenance for most commercial systems.
Myth #2: “Lowering the Thermostat Makes the Cooler Work Faster.”
It’s tempting to turn down the thermostat when temperatures start to rise, but this won’t make your system cool any faster. In fact, it forces the compressor to work longer and harder, increasing energy costs and system strain.
The truth: Cooling performance depends on system capacity and condition, not thermostat settings. If your cooler isn’t reaching the right temperature, it likely needs cleaning, calibration, or repair — not colder settings.
Myth #3: “All Refrigerants Are the Same.”
Refrigerants aren’t interchangeable. Using the wrong type can cause inefficiency, damage components, or even violate environmental regulations. Some older refrigerants, like R-22 or R-404A, are being phased out due to high global warming potential (GWP).
The truth: Modern low-GWP refrigerants improve efficiency and comply with EPA standards. Buffo’s Refrigeration can retrofit your system to use approved, eco-friendly options that perform better and save money.
Myth #4: “Energy Efficiency Upgrades Are Too Expensive.”
While it’s true that upgrading to energy-efficient compressors, fans, or smart thermostats requires an initial investment, the long-term savings are substantial. Lower energy bills, reduced maintenance costs, and extended system life quickly offset the upfront expense.
The truth: Most businesses see a 20–40% drop in energy use after efficiency upgrades. Many utilities also offer rebates or tax incentives, making the investment even more affordable.
Myth #5: “Closing Off Air Vents Helps Save Energy.”
Some store managers believe blocking off vents or restricting airflow can save energy. In reality, this disrupts circulation and causes uneven cooling, forcing the compressor to run longer and work harder.
The truth: Proper airflow is essential for consistent temperatures and efficient operation. Keep vents, fans, and coils clear to maintain optimal performance.
Myth #6: “Refrigeration Problems Always Require New Equipment.”
Not every cooling issue means you need to replace your system. Many performance problems are caused by dirty coils, faulty sensors, or worn gaskets — all of which can be fixed quickly and affordably.
The truth: A professional inspection from Buffo’s Refrigeration can pinpoint the issue and recommend the most cost-effective solution, whether it’s a simple repair or an upgrade.
