Your air conditioner plays a critical role in keeping your home cool and comfortable during the summer. It can be frustrating to discover that your AC unit is not blowing cold air on a hot day. A broken air conditioner requiring an AC repair can cause excess humidity in your home, aggravating indoor air quality issues. The following are some reasons why your AC unit might run and fail to blow cold air.
Incorrect Thermostat Settings
The thermostat is the first thing you should check whenever your AC unit is not blowing cold air. It might be possible that someone in your household has interfered with the thermostat and changed the temperature settings. Ensure that it is set to “cool.” If everything with the thermostat seems fine, you should check for other issues.
Clogged or Dirty Air Filters
Your AC system has an air filter responsible for filtering dust, debris, pet dander, and other particulates and preventing them from circulating in the indoor air. It also keeps the system’s inner components cleaner, which makes them operate efficiently. Thus, a dirty or clogged air filter can impede airflow, which can reduce cooling inside of your house. In serious cases, it can make your system shut down completely. You can ensure this does not happen by changing the air filter once every one to three months during routine maintenance.
Frozen Evaporator Coils
The indoor unit of your AC system has an evaporator coil, which is responsible for removing heat and moisture from the indoor air. With time, dust and debris can build over these coils, reducing their heat-removing capability. The moisture from the indoor air can also freeze over the coils, completely impeding the heat exchange process. Signs of frozen evaporator coils include inadequate cooling and higher energy bills.
Refrigerant is a chemical component that facilitates the air-cooling process inside of your system. It draws heat and moisture from the indoor air and releases it outside. If this chemical starts to leak, your unit’s cooling capability goes down significantly. The result is that your equipment will run for extended periods and may not cool your home.
There are several potential reasons why your AC unit is running but not blowing out cold air. These might be as simple as altered thermostat settings or as complex as leaking refrigerant. In any case, you must quickly resolve these issues before your air conditioner shuts down completely.
