There are many reasons why an air conditioner is not blowing cool air, and some of the solutions can be very simple. But if you try troubleshooting your air conditioning and cannot find the problem, then you should call in a professional to get the job done right. Older air conditioners tend to lose efficiency and become problematic until they are replaced. But if you are trying to get the most out of your air conditioner, then it helps to understand the basic reasons why the cool air is not flowing.
The Thermostat Is Not Set Properly
When you set the temperature for your air conditioner, you should also check to make sure that your thermostat is set to “auto” and not “on.” When the thermostat is set to on, the fan continuously blows regardless as to whether or not the air conditioner is running. Not only does this waste energy, but it circulates the warm air in the house and makes it feel like your air conditioner is not working.
The Air Filter Needs Changing
Your air conditioner, just like your furnace, has a filter that keeps debris from the outside from getting into the inner-workings of your unit. Your air conditioner requires a regular flow of air to work properly, and a clogged filter prevents air from flowing. You can see if your filter is dirty or not simply by pulling it out of your air conditioner and looking at it. A mostly white filter is just fine, while a gray filter needs to be replaced.
Check Your Condenser
The exterior portion of your air conditioner that sits in your backyard is called the condenser. When there is build up on the coils in your condenser, refrigerant is not going to flow as easily as it show. Grass and weeds that grow into the condenser can also affect the coils and make it difficult for your air conditioner to create cool air. You need to clean the dirt off the coils and pull the weeds and grass out of your air conditioner to get the cool air flowing again.
Something That A Pro Should Handle
Other reasons for no cool air include a low level of refrigerant, a damaged condenser, and a refrigerant leak. These are not issues you want to handle on your own as they can be complicated and potentially dangerous if you handle the refrigerant incorrectly. If you tried your other troubleshooting methods and you still do not have cold air, then it is time to call in a professional and get your air conditioner up and working again.
One of the best ways to avoid these kinds of problems with your home heating and cooling systems is to get them inspected once a year by a certified professional technician. An expert can see problems starting, and take the necessary steps to prevent the problems from getting worse. When you have a professional look over your HVAC systems each year, you can keep your repair bills down and get more from your unit before it needs to be replaced.
