Keep reading and stay cool throughout the summer months.
Power Issues
First, check if the AC unit has power and then look at the circuit breaker and fuse box. A blown fuse or a tripped breaker can be the cause of your AC compressor not turning on.
Reset the circuit breaker and change the fuse if needed. Remember to check that the power switch is turned back on.
Thermostat Problems
Sometimes, the issue lies with the thermostat. Ensure it is set to “cool” and the temperature is lower than the room’s temperature.
Dead or low batteries in the thermostat can also prevent the AC compressor from turning on. Replace the batteries and see if that solves the problem.
Dirty Air Filters
Dirty air filters can limit airflow, causing the AC compressor to shut down to prevent overheating. Routine air filter cleaning is an essential part of AC maintenance if you want good air quality and a healthy environment.
Refrigerant Levels
Low refrigerant levels can prevent your AC compressor from turning on. If you suspect a refrigerant issue, it’s best to call a professional for home HVAC repair, as dealing with refrigerant requires specialized knowledge and equipment.
Capacitor or Starter Relay Issues
If the capacitor is faulty, the compressor won’t start. Similarly, a defective starter relay can stop the compressor from turning on. Both parts can wear out over time and may need replacing.
Preventative AC Maintenance Tips
Schedule regular maintenance inspections with a professional to find possible issues before they become major problems. This includes:
- Checking refrigerant levels
- Inspecting electrical components
- Ensuring overall system health
Routinely clean the outside of your AC unit and remove any obstructions. This keeps the airflow going and prevents overheating.
Change air filters every 1-3 months, depending on usage and manufacturer recommendations. Clean filters improve airflow and system efficiency.
Ensure your thermostat is working and set to the right mode and temperature. You should also periodically replace the batteries.
Check that the condensate drain is clear to prevent water backup. This can lead to mold growth and moisture issues.
Look for leaks or disconnected ducts, which can waste energy and reduce cooling efficiency.
