When the first hot day arrives and your air conditioner is not keeping up, a few quick checks can save you time. Some problems are simple. Others need a professional.
Quick checks you can do safely
- Thermostat. Make sure it is set to cool, set below the room temperature, and has fresh batteries if it needs them.
- Breaker. Check that the breaker for your air conditioner has not tripped.
- Air filter. A clogged filter reduces airflow and can cause cooling problems.
- Vents. Make sure supply vents and return grilles are open and unblocked.
- Outdoor unit. Clear leaves, grass and debris from around it, and keep plants trimmed back.
When to turn it off and call
If you see ice on the refrigerant lines or the unit, turn the system off and let it thaw. If the unit makes loud noises, smells like burning, or leaks water inside your home, switch it off and call a technician. Running it can make the problem worse.

Common reasons an air conditioner stops cooling
- A dirty filter or blocked vents restricting airflow.
- A dirty or blocked outdoor unit.
- Thermostat settings or a thermostat problem.
- Electrical issues such as a tripped breaker or failed part.
- Refrigerant or compressor problems, which need a professional.
Keep your AC running well all summer
Replace the filter regularly, keep the outdoor unit clear, and have the system tuned up before the hot weather. If you are thinking about upgrading, ask about ductless mini-splits for rooms and additions.
