When temperatures drop, most homeowners stop thinking about their air conditioner altogether. After all, it’s not running, so what could go wrong? Surprisingly, winter is when many of the most common AC mistakes occur.
Below are the most common winter mistakes that can quietly damage your air conditioner and what you should do instead.
Ignoring Your Outdoor Unit All Winter
Even though your AC is turned off, the outdoor condenser is still exposed to the elements. Snow, ice and fallen leaves can build up around the unit and cause corrosion or physical damage. Make it a habit to periodically inspect the area around your unit. Clear away any leaves, ice and other debris that can block proper airflow.
Covering the Unit Incorrectly
Covering your AC can be helpful. However, it needs to be done properly. Fully wrapping the unit in plastic can trap moisture inside, which can lead to rust, mold and electrical issues. If you choose to cover your unit, use a breathable cover that’s specifically designed for air conditioners. It’s also recommended that you cover only the top of the unit rather than sealing it completely.
Letting Snow and Ice Pile Up
Heavy snow and ice accumulation can bend fan blades and add unnecessary weight to the unit. Melting snow can also refreeze inside the system, creating expansion-related damage, which is expensive to repair.
After a major snowfall, gently remove any buildup from the top and sides of the unit using a broom. Never use a shovel or sharp tool, as both can damage both the inside and outside of the unit.
Skipping Winter HVAC Maintenance Altogether
Homeowners typically don’t think about maintaining their HVAC system during winter, but it’s actually the best time to check in on your HVAC system. Small issues that go unnoticed now can quickly turn into bigger problems once summer arrives. Replacing the air filters, checking insulation on refrigerant lines and scheduling a professional inspection can ensure your system is ready when you need it most.
Running the AC on Warm Winter Days
It might be tempting to turn on the AC during an unexpected warm spell, but doing so when it’s cold outside can strain the compressor and other components. Most AC systems aren’t designed to operate efficiently below certain temperatures.
If indoor comfort is an issue during winter, adjusting ventilation or using ceiling fans is a better alternative.
