Many homeowners make a critical mistake at the time they learn to shut off their AC unit properly. This mistake could cost them dearly. A frozen HVAC system during winter can get pricey and create an inconvenient problem in your home. The peaceful snow you see in winter months can substantially affect your HVAC system’s condition and performance.
Your air conditioner won’t tolerate temperatures below 60 degrees Fahrenheit – a fact most people don’t realize. Ice buildup becomes a serious concern as temperatures drop below freezing. This can lead to component freezing, performance issues, or sudden breakdowns. The good news is that you can save money on energy costs and keep your unit ready for warmer weather by turning off your AC the right way.
Why You Shouldn’t Rush to Shut Off Your AC
You might think shutting off your AC when temperatures drop is smart, but it can cause unexpected issues. Most homeowners turn off their units as soon as fall arrives to save money. This quick fix might end up costing more down the road.
Your AC works as part of a complete HVAC system. Smart maintenance goes beyond just flipping a switch and forgetting about it until summer. The right preparation protects your investment and helps your unit last longer.
On top of that, it helps to know that today’s AC units have parts that work all year long. The thermostat keeps track of indoor temperature whatever the season. Some systems even share components with your heating setup. A complete shutdown without proper steps can affect your home’s entire comfort system.
What Can Go Wrong If You Shut It Off Improperly
Your AC unit can face serious problems if you don’t shut it down properly for winter. The compressor, one of the most expensive parts to replace, often gets damaged when the AC runs below 60°F. Cold weather makes the compressor’s lubricant too thick, which prevents proper lubrication and causes overheating.
A homeowner learned this lesson painfully after switching off their heat pump at the breaker during cold nights. The unit failed completely when they tried starting it in single-digit temperatures. The damage likely occurred in the compressor’s reed valves.
Idle AC units face a big enemy – moisture. When snow melts and refreezes on the internal parts, the coils and electrical components can rust and corrode. The ice that forms around these critical parts might stay frozen for long periods.
How to Prepare Your AC Unit for Winter the Right Way
Your AC unit needs proper winter preparation to protect your investment from damage. The first step is to find your AC unit’s electrical circuit, which you’ll usually spot near the outdoor unit, and switch it off. This simple action prevents accidental operation on warm winter days that could cause freeze damage when temperatures drop again.
Power needs to go off before you start cleaning the outdoor unit. You should remove all debris like leaves, twigs and grass clippings, then give it a good rinse with your garden hose. The unit needs to dry completely before you move to the next step.
Experts don’t agree on the best covering method. Some experts recommend using breathable, waterproof covers, while others suggest just placing a weighted piece of plywood on top. You should avoid complete plastic covers since they can trap moisture and lead to rust and mold problems.
