A/C & Heating Diagnosis & Repair

A/C and heating problems can come from refrigerant leaks, compressor faults, blend-door issues, blower motor failures, or electrical controls. We test the system at your location and identify the actual cause before recommending repairs.

Common symptoms

  • "My A/C is not blowing cold air"
  • "The heater is weak or only blows cold"
  • "The blower motor does not work on some speeds"
  • "I hear noise when the A/C is turned on"

What we check

  1. 01 A/C compressor command, clutch operation, and related electrical controls
  2. 02 Refrigerant pressure behavior and leak testing at accessible components
  3. 03 Blower motor, resistor, fuses, relays, and cabin airflow
  4. 04 Blend-door and mode-door operation when heat or vent direction is incorrect
  5. 05 Cooling fan operation when A/C performance changes at idle

Heating and air conditioning diagnosis starts by separating airflow problems from temperature-control problems. A weak blower, stuck blend door, low refrigerant charge, failed compressor, or electrical fault can all feel similar from the driver seat.

Many A/C and heating repairs can be completed on-site after diagnosis. Repairs requiring refrigerant recovery, evacuation, major HVAC-box disassembly, or specialized equipment may require shop service.
