Auto AC & Heater Repair in Simi Valley

If your car AC isn't blowing cold air, it's often due to low refrigerant levels from a leak in hoses, seals, or the compressor, which prevents proper cooling in your auto AC & heating system. Other common culprits include a faulty compressor clutch that won't engage, a dirty condenser clogged with debris blocking heat release, or a clogged cabin air filter restricting airflow. Electrical issues like blown fuses or bad sensors can also stop the system. At Perry's Quality Auto Repair in Simi Valley, CA, our ASE Certified technicians use specialized tools to diagnose refrigerant pressure, detect leaks with UV dye, and check components like the evaporator and blower motor. We repair or recharge as needed, backed by our 2-Year/24,000-Mile warranty. Stop sweating and come in for a diagnostic to get cool air flowing again.

A refrigerant leak in your auto AC & heating system is the top cause of warm air from vents, as low levels mean the evaporator can't absorb cabin heat effectively. Look for oily residue around AC hoses, O-rings, condenser, or compressor shaft seal; hissing sounds; or the compressor cycling on and off rapidly. Ice on lines or poor cooling performance are other signs. Simply recharging without fixing the leak lets moisture in, damaging the compressor. Perry's ASE Certified techs in Simi Valley perform pressure tests, electronic leak detection, and UV dye checks to pinpoint issues in the expansion valve, drier, or fittings. We seal leaks, flush the system if needed, and recharge precisely. All backed by our 2-Year/24,000-Mile warranty. Have it inspected today to avoid bigger repairs.

Your auto AC & heating compressor's failure stops refrigerant circulation, leaving you with no cold air. Common symptoms include the clutch not engaging (no click or spin when AC is on), grinding or squealing noises from the front of the engine, warm air despite full refrigerant, or visible leaks at the shaft seal. Overheating from low oil or debris can seize it. Don't ignore—failing compressors spread metal shavings, contaminating the condenser, evaporator, and lines. At Perry's Quality Auto Repair, our family-owned shop since 2000 uses diagnostic gauges and scopes to confirm clutch, electrical, or internal issues. We replace with quality parts, flush the system, and recharge, all warrantied 2-Year/24,000-Miles. Come in for a quick check to restore reliable cooling.

Weak airflow from your auto AC & heating vents often stems from a clogged cabin air filter trapping dust and debris, reducing blower efficiency. A failing blower motor, faulty resistor, or blocked evaporator drain can also limit air. Dirty condenser fins from road grime restrict overall system performance. These issues make cooling feel inadequate, especially in Simi Valley heat. Perry's ASE techs inspect and replace the cabin filter (easy maintenance), test blower speeds, clean the condenser, and clear evaporator blockages. We ensure strong flow through hoses and ducts. Repairs come with our 2-Year/24,000-Mile warranty. Check your filter first, but schedule a diagnostic for full system health and crisp, powerful cool air.
