Frequently Asked Questions

An AC running but not cooling usually points to restricted airflow, incorrect refrigerant charge, failing components, or thermostat/control issues. The most common cause is a clogged filter or dirty coil that blocks heat transfer and shrinks cooling capacity. We service homes throughout the Orlando North area, including Lockhart neighborhoods, so we see these patterns daily. Our technicians diagnose by checking refrigerant levels, electrical connections, safety controls, and airflow through the ductwork, then explain options with upfront pricing. Same-day and 24/7 emergency repairs are available when cooling is lost. On many summer calls, I find a filter that looks clean but is packed with fine dust, cutting output dramatically.

Try these quick checks before calling:

  • Confirm thermostat is set to Cool, Fan on Auto, and setpoint below room temp.
  • Replace a dirty filter and ensure indoor vents are open.
  • Clear debris around the outdoor unit for full airflow.
  • Look for ice on refrigerant lines or the indoor coil and note any tripped breakers.

If you see ice, burning smells, or repeated breaker trips, turn the system off and schedule a professional diagnostic.
