Window Air Conditioner Tips to Help Keep You Cool this Summer

Winter has finally given way to Spring and most of the country is getting into the warm spring weather and lots of folks are already cranking up their air conditioners. Is it warming up where you are yet? Well, before you know it, the sweltering heat of summer will be squatting down on you like a sweaty sumo wrestler and you’ll need that air conditioner cranking out all the cold air you can get! Here are some tips to make sure your window air conditioner is ready to keep that sumo wrestler off of you this summer!


1. Replace/clean filter every month
Window air conditioners (or through-the-wall units) are outfitted with a simple electrostatic filter or framed mesh filter in the front grill area to filter the air that passes through them – you’ll need to clean this filter before hooking up the unit for the season, and then monthly during the cooling season.

This filter does two things: 1) it removes some of the particulates circulating around the room for better hygiene and health and 2) maybe more importantly, it protects the evaporator coil (the one that makes the cold air) inside the air conditioner and helps keep it from getting coated with an insulating layer of gookus, which reduces efficiency, costing you more money to run it, and keeps it from cooling as well.

If the filter is deteriorating or ripped, replace it! Air conditioner filters are inexpensive and easy to replace. You can buy a replacement filter for any type or brand of window air conditioner, including electrostatic, cut-to-fit, and framed mesh filters.


2. Clean condenser coils annually
The condensing coils at the back of a window air conditioner get really icky over time. Since the dirt tends to accumulate on the inside of the coils, you will need to remove the entire cover, then blow compressed air or use a soft bristle brush to clean them. You should also clean any dirt or lint build-up in the bottom of the air conditioner, so the condensed water will be picked up by the condensing fan slinger.

3. Store the unit in a basement or utility room, NOT a garage
You might find an unpleasant surprise when you take out your window air conditioner especially if you stored it in a garage or outdoor area… small, furry critters like to set up house inside these units and can cause all kinda damage inside by chewing wires and leaving various excretions all over controls and electronics. You can also catch wicked-nasty diseases, like rabies and hepatitis-C, by simply inhaling excrement-laden particles as they’re blown into the room when the air conditioner is put back into service.

Something else to watch out for if you left your air conditioner uncovered in a window is wasps and birds may have built a nest inside the unit. Be careful! We recommend that you store your unit in a basement or other storage area of the home or install a cover when being stored in the window.


Tip: Don’t short cycle the cooling system
Wait at least ten minutes after shutting the air conditioner off to allow the pressure in the refrigeration system to equalize before turning it back on again. This will prolong the life of the compressor.
