Auto A/C & Heating Repair in Petaluma
Climate control not working? We diagnose and repair auto HVAC systems to keep you comfortable year-round.
A car that won't hold a comfortable temperature usually isn't one problem -- it's a system with a leak, a failing part, or airflow that's not moving where it should. We trace it back to the actual cause instead of just topping off refrigerant and sending you on your way.

- A/C blowing warm instead of cold
- Weak airflow from the vents, even on high

Every repair is backed by Accu-Line's NAPA Auto Care nationwide warranty.
Frequently Asked Questions
Why is my A/C blowing warm air?
Usually a refrigerant leak, though it can also be a failing compressor or a blend door issue on the heating side. We diagnose the actual cause rather than just topping off refrigerant and sending you out the door.
How often does A/C need to be recharged?
A properly sealed system shouldn't need regular recharges -- if yours needs one often, that usually points to a leak somewhere that's worth finding and fixing rather than topping off again and again.
My heater isn't warming up -- what's usually wrong?
Often low coolant, a stuck thermostat, or a failing heater core. We test the system rather than guessing at which part to replace first.
Why does my A/C smell musty when it kicks on?
Usually mold or mildew buildup in the evaporator or a dirty cabin air filter. A filter replacement often clears it up; a persistent smell can mean something further into the system.
Is a cabin air filter replacement part of a heating or A/C service?
It can be, and it's an easy thing to overlook -- a clogged cabin filter cuts airflow and can cause that musty smell. Worth mentioning if it's been a while since yours was changed.
