During summer, homeowners rely on their air conditioners to provide a much-needed respite from the heat. Unfortunately, air conditioners tend to break down mid-season due to overuse or poor maintenance. When this happens, the units may start to blow warm air instead of cold air. What should you do if you encounter this problem? Below are some dos and don'ts for when your AC blows warm air into the home.
Troubleshoot the Air Conditioner
Various problems can cause your air conditioner to blow warm air into the home. Some are minor issues, while others require professional repairs. Therefore, before you call your AC contractor, you can troubleshoot the unit to determine the cause of the problem. Check for the following faults:
- Dirty air filter: Have you changed or cleaned your AC filters recently? If not, these could have caused the unit to blow warm air. Clean the filters to eliminate clogs and improve airflow.
- Low refrigerant: If your unit starts short-cycling before blowing warm air, it is probably low on refrigerant. You need expert help to recharge the refrigerant and locate and fix the leak.
- Frozen evaporator coils: Check your AC evaporator coils for frost buildup. These coils can freeze up in summer due to malfunctions and poor airflow to the unit.
- Thermostat problems: Make sure the reading on your thermostat is correct. If you have a faulty thermostat, it may fail to signal the AC to cool the room to the desired temperatures.
As you troubleshoot your AC, check the circuit breaker to ensure it hasn't tripped. A tripped breaker will cut off power to the AC, causing the unit to shut down.
Don't Keep Running the AC
When your AC starts to blow warm air, you may decide to leave it on, hoping the problem will go away. However, running your AC can worsen the problem and lead to costly repairs. For example, running an air conditioner with low refrigerant may cause the compressor to overheat and shut down. Similarly, if your AC has frozen coils, leaving it on can cause damage to other adjacent components. Therefore, shut down the unit to prepare for repairs.
Don't Attempt DIY Fixes
Summer is a busy season for most AC contractors, and sometimes, getting immediate services may be costly. Therefore, you may be tempted to repair the unit by yourself to save time and money. This approach can cause further damage to the AC. Do not attempt DIY repairs, as they can become expensive in the long run. If you want fast and efficient repairs, find a 24-hour emergency service.
