When the dog days of summer hit, it’s important that your air conditioner is up and running properly. To ensure you’ll get cooling relief all season long, there are a few tips and tricks you should know about your air conditioning unit.

How Your Unit Works

Your air conditioner uses refrigeration to keep your home cool. Compounds called refrigerants work within the coils of the unit to absorb heat as it changes from a liquid to a gas state. A compressor in the unit puts extra pressure on the gas which makes extra heat. Condenser coils push the extra heat to the outdoors. The refrigerants keep the inside of your home cool, with the help of your interior walls. Fans, coils, and refrigerant are used in a cycle within your air conditioner to keep it running.

Common Problems with Air Conditioners

When your unit is no longer running properly, there can be quite a few causes.

If there is no cold air, you may need to replace the filter or clean the coils. If those repairs don’t fix the problem, the compressor may need to be replaced or you may have a leak.

If you notice that your unit is making more noise than usual, it may be a sign that the compressor needs replaced. With older units, losing efficiency is a common problem that results in increased cooling costs. Increased cooling costs for a new unit could be a result of wiring issues.

If you notice leaking, there could be an internal breakdown. Low refrigerant could cause the unit to freeze and thaw.

How Long Will the Unit and Parts Last?

On average, air conditioners last about 20 years with routine maintenance. Individual parts do not typically last that long, though. Compressors, coils, and fans will usually need to be replaced, as they do most of the work. If these parts are serviced in time, there will be no need to replace the entire unit, saving you money.


If you’re experiencing air conditioning problems, it can be a result of faulty wiring, frozen coils, low refrigerant, an old thermostat, or broken fans. To ensure the problem gets fixed in the proper way, call a licensed and experienced technician, like WeatherKing.
