Prepare Your Air Conditioning System for Summer
I know it seems a long way off given the amount of snow we’ve had in the past month. However, summer is just around the corner, and you need to be ready for it. As soon as the snow melts, get your air conditioning system ready for summer so you're not caught off-guard when a hot day rolls around.
To prep your unit for the upcoming months, inspect it for any obvious signs of damage or rust, which could cause leaking. Clean any debris in the water pan and check the fan belt tension (it should move about one half inch when pressed). Oil the motor and bearing on the blower. Install new cooler pads. Reconnect the water supply. Once the water supply is turned on, make sure the float valve is operating properly.
Window Air Conditioner
If you didn’t get a chance to properly maintain your window unit when you pulled it out last fall, start by checking the unit for any insect or small animal nests. Clean the filter. This is something you will want to do on a monthly basis throughout the season. Carefully clean the condenser coils taking care not to bend them. Consider using compressed air or a soft bristle brush. Clean out the water pan to prevent any mold from growing. At the end of this season, perform all of these maintenance steps again before putting the air conditioner into storage in the garage or basement.
A central air unit is a more complex system with sealed components: a condenser and an evaporator. I would recommend hiring a professional if you have this type of cooling system.
