Common AC Problems We Fix

Our technicians are trained to diagnose and repair every type of air conditioning failure, from minor issues to full system breakdowns. Here are the most common problems we handle daily:

  • AC not cooling or blowing warm air
  • Unit freezing up or icing over
  • Refrigerant leaks and low Freon levels
  • Faulty compressor or capacitor failures
  • Condenser and evaporator coil problems
  • Electrical failures and tripped breakers
  • Thermostat miscommunication issues
  • Unusual noises — banging, hissing, squealing
  • AC short-cycling or won't shut off
  • Drainage clogs and water leaks

Our Diagnostic & Repair Process

We never guess. When we arrive at your home or business, our technician performs a systematic diagnostic that covers every major component — from the thermostat and control board to the compressor, refrigerant lines, and electrical systems. You receive a written diagnosis with a firm, upfront price before any repair begins.

No Surprise Charges

Our flat-rate pricing means the price you approve is the price you pay. We never add hidden fees or charge extra for after-hours emergency service.

All AC Brands Serviced

We stock OEM-compatible parts for all major manufacturers including Carrier, Trane, Lennox, Rheem, Goodman, York, Bryant, American Standard, Amana, and more. This means faster repairs — fewer trips to the supply house, less downtime for you.

When Should You Repair vs. Replace?

If your AC is under 10 years old and the repair cost is less than 50% of a new unit's cost, repair is almost always the better option. Our technicians will give you an honest recommendation — we never push unnecessary replacements.
