Your AC is running, but the air feels warm

Use these practical checks to narrow down what may be happening without trying to diagnose or repair the system yourself. If the problem continues, the Air Conditioning Repair service path is the right next step.

What to check first

Check that the thermostat is set to cooling and that the filter is not visibly dirty. ENERGY STAR advises homeowners to inspect, clean, or change central AC filters about once a month because dirty filters can increase energy use and damage equipment.

What warm air may indicate

Warm air can have more than one possible explanation. A dirty filter is one possibility, especially if airflow is reduced. If the thermostat and filter look normal but the AC still blows warm air, the system may need a professional inspection. Avoid opening panels or attempting electrical repairs.

When to contact an AC repair professional

Contact an air conditioning repair professional if the system continues blowing warm air after you check the thermostat and filter, or if you are unsure what you are seeing. A technician can inspect the equipment and explain the repair options without requiring you to troubleshoot electrical or mechanical parts.

Choose the service that matches the problem

Because the symptom is an AC that is not cooling, choose Air Conditioning Repair rather than a general home-service category. Confirm that the company serves your Sacramento address and handles the type of air-conditioning system in your home.

Questions to ask an AC repair company

  • Do you service my type of air-conditioning system?
  • Can you inspect the cause of the warm air before recommending a repair?
  • What work is included in the diagnostic visit?
  • Will you explain the repair and any alternatives before starting?
  • Do you serve my Sacramento address?
