Air conditioning systems are reasonably robust and weather-resistant. For the most part, you don't need to worry about your air conditioner failing over the winter when you aren't using it. Of course, this doesn't help you if you know that your AC has existing problems. You may have put off repairing them over the summer and fall, but is it too late now that winter has arrived?

You can typically repair (or even replace!) an air conditioning system at any point during the year, but there are some exceptions and caveats to keep in mind. If you want to get your air conditioning system back in tip-top shape before the warm weather arrives, then keep these three considerations in mind.

1. Condenser Unit Repairs Will Require Access

Your condenser unit is the large outdoor portion of your home's air conditioning system. This box contains your compressor, condenser coils, condenser fan, and some associated plumbing and electrical hardware. If you know you have a problem with the condenser unit, or if your air conditioning system has a problem you haven't yet diagnosed, then your technician will need outside access.

Accessing this unit shouldn't usually be a problem for most homes, but it may be challenging if you live in an area where a large amount of snow sits on the ground all winter. In these cases, make sure you clear snow from a path to the unit and the area around it. Keeping this area clear can also help to prevent damage from excessive moisture once the snow melts.

2. You Can't Run Your AC in Cold Weather

You probably don't ever feel the need to run your air conditioner in freezing weather, and that's a good thing for your system's health. Your air conditioner's refrigerant and oil will not function correctly in cold weather, and you can potentially freeze your evaporator and overwork your compressor. Fortunately, your system probably has a temperature sensor that prevents the compressor from engaging at all.

Unfortunately, this has some implications for repairs. Your technician can't turn your system on to test it, which can make diagnosis challenging. You may be able to replace known failed components, but other repairs may need to wait for a streak of warm days.

3. Warm Weather Can Show Up At Any Time

Seasons can be unpredictable, and hot spring weather can arrive sooner than you might expect. Putting off repairs into the winter can leave you at the mercy of the weather and may force you to endure some unseasonable scorchers without a functional AC. Although you can repair your system over the winter, it's best to deal with any issues that arise as soon as you can.
