AC not blowing cold? In the San Fernando Valley heat, you need your AC working. We diagnose and repair all car air conditioning systems.
Call (818) 500-1939When temperatures in the San Fernando Valley climb past 100 degrees, a broken car AC isn't just uncomfortable — it's unbearable. Whether your AC is blowing warm air, making strange noises, or not working at all, the problem won't fix itself. The longer you wait, the more damage can occur to the compressor and other expensive components.
At A Plus Auto Shop, we don't just top off your refrigerant and send you on your way. We perform a complete AC system diagnosis including leak detection, pressure testing, and component inspection. This way, we fix the actual problem — not just the symptom — so your AC stays cold for the long haul.
Comprehensive ac repair & recharge services for all makes and models at A Plus Auto Shop.
Low refrigerant is the most common cause of warm air from your AC. We evacuate the old refrigerant, vacuum test the system for leaks, and recharge with the correct amount and type of refrigerant specified for your vehicle — R-134a or R-1234yf.
The compressor is the heart of your AC system. When it fails, you get no cold air at all. We diagnose compressor issues — whether it's a clutch failure, internal damage, or an electrical problem — and replace it with a quality unit when needed.
Refrigerant leaks can occur at hose connections, the condenser, evaporator, or compressor seals. We use UV dye and electronic leak detectors to find even the smallest leaks and repair them so your system holds its charge.
The condenser (in front of the radiator) and evaporator (inside the dash) are heat exchangers that make your AC work. Road debris can damage the condenser, and evaporators can develop leaks over time. We repair or replace both.
If you hear your AC running but feel no air coming from the vents, the blower motor or resistor may have failed. We diagnose and replace blower motors, resistors, and blend door actuators to restore proper airflow.
AC systems rely on sensors, relays, switches, and control modules. A faulty pressure switch, bad relay, or wiring issue can prevent the compressor from engaging. We trace electrical problems to their source and repair them.
Answers to common questions about ac repair & recharge at A Plus Auto Shop.
The most common causes are low refrigerant (from a leak), a faulty compressor, a clogged expansion valve, a bad condenser, or an electrical issue preventing the compressor from engaging. A professional diagnosis will pinpoint the exact cause.
A properly sealed AC system should not need regular recharging. If your AC needs refrigerant, it means there's a leak somewhere in the system. We recommend finding and fixing the leak rather than just adding refrigerant, which will leak out again.
AC repair costs vary depending on the issue. A simple recharge is more affordable than a compressor replacement. We diagnose the problem first and provide an upfront estimate before any work begins. Call (818) 500-1939 for details.
We don't recommend DIY AC recharge kits. They can overcharge the system (damaging the compressor), introduce moisture and contaminants, and mask underlying leaks. Professional service ensures the correct refrigerant amount and identifies any problems.
