Most types of air conditioning repair are best left to a professional who has the right tools and parts needed to do the job. However, you might be able to do some things, such as clean parts that are so dirty the AC malfunctions. You can also check the filter and change it, verify the thermostat settings, and check the power supply. If you can't figure out what's wrong with your AC, then calling a repair service is the next step. Here are a few reasons your AC can't keep you cool.
1. The Refrigerant Is Leaking
Refrigerant problems have to be fixed by an air conditioning repair technician since you have to be licensed to handle refrigerant. Low refrigerant makes it difficult for your AC to keep you cool. If the refrigerant is leaking, the problem will get worse until your AC won't be able to cool your home at all.
Fixing a refrigerant problem involves hunting down the leak and patching it. This might be done by soldering a copper refrigerant line and then filling the refrigerant to the proper level.
2. The Indoor Blower Isn't Turning
Your AC might be making cool air but the air won't be distributed through your house if the blower in the air handler isn't working. This problem could happen if the capacitor that powers the blower motor goes bad or if the blower motor burns out.
The AC repair technician can fix this problem by putting in a new capacitor or new motor. These parts might go bad if the blower fan gets dirty and isn't cleaned before the start of the summer season. Keeping your AC clean and changing the filter regularly can prevent problems with the blower.
3. One Of The Refrigerant Coils Has Ice On It
When refrigerant coils get dirty, they can actually grow ice and ice over. That makes it impossible for your AC to function properly. If you see ice on your air conditioner, call an air conditioning repair service for help. They may want you to shut your AC off so the ice will melt before the repair technician arrives.
Once the ice is gone, the technician can check the coil. If a coil is coated with grimy dust, your AC may start working again once the coil has been cleaned. Other things can cause your AC to ice over though, so your air conditioner might need parts repaired to get it working properly again. Anything that restricts airflow across the coils could also cause this problem such as blower issues, a clogged filter, a broken condenser fan, or wiring problems.
