The end of the cooling season doesn’t mean the end of AC maintenance. Before you put your air conditioner to bed for winter, a few simple maintenance tips will help ensure that it’s ready to keep you comfortable when you wake it up again next spring. Seasonal start-up is often the time when system problems occur, often because basic end of season AC maintenance was neglected months ago when the system was shut down. Here are some things to take care of now:
- Power down the central air conditioner unit. This ensures that nobody turns the system on at the thermostat accidentally during the winter by selecting “Cool” instead of “Heat.”
- Remove the system air filter and replace it with a fresh one. Central A/C and heating systems share the same filter. Don’t start the winter heating season with a dirty air conditioning filter left over from the summer.
- Inspect the condensate drain pan. Situated under the indoor air handler, this wide flat pan collects condensation dripping off the evaporator coil while the air conditioner’s running. Make sure there is no standing water in the pan. Residual water left in the pan will spawn algae and mold growth over the winter. If you notice standing water, that usually means a clog somewhere in the condensate drain system. Contact a qualified HVAC service provider to restore drain function.
- Clear the outdoor unit. Make sure there are no fallen leaves or branches in the fan opening on top. Also, clear away weeds or other vegetation to leave two feet of open space on sides. Consider a commercially-available vented A/C cover that slips over the unit to protect it during the winter, available in sizes to fit your air conditioner.
- Check it during the winter. Don’t allow heavy amounts of snow or ice to accumulate on the unit. If it’s located in an spot where icicles falling from the eaves above may strike it, place a piece of plywood or other protection atop the unit.
