When your air conditioner (AC) stops working in summer, it can be a scramble to get it fixed. Depending on the situation, there can be multiple reasons why your AC stops blowing cold air. Here are four things to check if your AC stops working to help resolve the issue and cool down your home as soon as possible:
1. Look at the Thermostat
Firstly, confirm that your thermostat is set correctly. Ensure that the thermostat is turned on and set to cooling operation. Wait a few minutes for the system to power up and see if your AC starts blowing cold air before moving on to the next troubleshooting step.
2. Clean or Replace the Air Filter
Dirty air filters can restrict or block AC airflow. In some cases, dirty air filters can shut down the system completely. To check if this is the issue, locate your air filter, turn off the AC, and inspect the filter. If you can’t see light through the filter, clean or replace it. A clean air filter will help your AC run efficiently and improve indoor air quality.
3. Clean the Condensor Unit
If your AC still isn’t blowing cold air, move on to the outdoor condenser unit. The condenser fan draws air into the outdoor unit through a tightly-wound condenser coil to remove heat from your home. Outdoor debris, dirt and grass can accumulate between the condenser coil fins, reducing energy efficiency, limiting cool air and potentially shutting down your AC system. Carefully vacuum the coil with a brush attachment and rinse gently with a hose. If this doesn’t fix the problem, it’s time to bring in the experts.
4. When to Call the Pros
Call the professionals if you think your evaporator coil may be frozen, you have a refrigerant leak, or your AC unit is undersized. The Hargrave Heating & Air Conditioning team can confirm that you have the right-sized AC unit for your square footage, insulation and climate. You may benefit from installing a Carrier ductless AC unit in problem areas or replacing your existing AC.
If your AC suddenly stops working in the middle of summer, you can rely on the experts at Hargrave and their crew on standby 24/7 for emergency services.
