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
- 01 A/C compressor command, clutch operation, and related electrical controls
- 02 Refrigerant pressure behavior and leak testing at accessible components
- 03 Blower motor, resistor, fuses, relays, and cabin airflow
- 04 Blend-door and mode-door operation when heat or vent direction is incorrect
- 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.
