What to Check When the AC Isn’t Cooling

air-conditionerWe’re technically into the fall season now, but we’re still experiencing some pretty hot days. You might be using your air conditioner during the day for a couple more weeks before turning it off for the season. That means that you still need to be careful about any issues that might develop with the system. One of the first signs people notice that their air conditioner is in trouble is when it stops cooling properly. If your air conditioner isn’t cooling your home the way it should be, there are a number of things you should check before calling for repairs.

The Thermostat

The number of times that an air conditioner “problem” turned out to be just an improperly configured thermostat would knock you out. Before you assume that something is physically wrong with the air conditioner, check your thermostat to make sure everything is reading properly. It’s possible that someone else in your home just changed it without telling you. If everything is displaying correctly, but the air conditioner still isn’t cooling, you may have a deeper issue. You should also call for professional repairs if the thermostat doesn’t seem to be working properly.

The Air Filter

Most homeowners aren’t even aware that their air conditioners include an air filter. The filter is designed to protect the system from the dust and debris commonly found in the ductwork of a home. While the filter is excellent at capturing contaminants before they can reach the air conditioner, it must be changed every three months or so. If it isn’t, the filter will eventually become clogged. This blocks most of the air flow from reaching the system, which prevents it from circulating air throughout the home. If your air conditioner doesn’t seem to be blowing much air at all, this might be why.

In order to check your air filter, look at the air conditioner and look for the junction at which the ductwork meets the system. This is the air return duct. There should be a latch or cover around that area. Open it, and pull out the current filter. If the filter looks like it should be replaced, try installing a new one and see if that fixes the problem. If the filter looks clean, or replacing it doesn’t fix the problem, you should call a professional for assistance.

The Vents

If you notice that the air conditioner output seems to be more limited in one part of your home than in others, it’s a good idea to check the vents in that area. Blocked vents can certainly prevent cool air from properly dispersing throughout a room, even if the air conditioner itself is in perfect health. If you don’t see any signs that the vents are malfunctioning, you might have a duct leak in that area that is diverting a large part of the system’s output. You’ll need to have a technician check that for you, though.
