Your vehicle’s HVAC system relies on a complex, pressurized mixture of refrigerant gas (Freon) and specialized oils. When your A/C stops blowing cold, it usually means that highly pressurized gas has leaked out of a cracked hose, failing seal, or a damaged compressor.
Buying a cheap “DIY A/C recharge can” from an auto parts store can actually over-pressurize and permanently destroy your A/C compressor. At Auto Star Service Center, we use professional, computerized evacuation and recovery machines to pull out old refrigerant, test your entire system for micro-leaks using UV dyes, and refill it to the exact manufacturer specifications.

Expert Climate Control Solutions
A/C systems don't "use up" freon—if you are low, you have a leak. We use advanced UV dye and pressure tests to find the exact source of the leak, repair it, and professionally recharge the system.
Your car's heater runs off the hot engine coolant. If your heater is blowing cold air, you likely have a clogged heater core, a bad engine thermostat, or dangerously low engine coolant.
Is your air blowing out of the floor vents when you set it to defrost the windshield? This points to a broken blend door actuator. We repair the intricate flaps and blower motors hidden inside your dashboard.
Symptoms of a
Failing HVAC System
Aside from the obvious lack of cold or hot air, look out for these subtle signs that your car's climate control system requires immediate mechanic attention.
If you turn on your heater and smell a sweet, syrupy odor, or if your windshield instantly fogs up with a greasy film on the inside, your heater core is leaking engine coolant directly into your cabin.
A foul, gym-sock or mildew smell when you turn on the A/C usually indicates mold/bacteria growing on your A/C evaporator core, or a severely clogged cabin air filter that needs immediate replacement.
If the fan is set to high but barely any air comes out, or if you hear a loud whining/whirring noise from behind the glovebox, your blower motor is failing or the blower motor resistor has burnt out.

Heating & A/C FAQ
Common climate control questions from our Graham and Puyallup customers.
The most common reason an A/C system blows hot air is a refrigerant (Freon) leak. The system is sealed, so if it's low, there is a leak somewhere—usually a cracked O-ring, damaged hose, or punctured condenser. Other causes include a failed A/C compressor, a broken blend door actuator (the flap that mixes hot/cold air), or an electrical relay issue.
Technically, never. A vehicle's air conditioning system is a closed, sealed loop. It does not burn or consume refrigerant over time like a car consumes oil. If your A/C needs a recharge, it means you have a physical leak that must be diagnosed and repaired before refilling the system, otherwise the new gas will just leak out again.
Your car's heater generates heat by routing hot engine coolant through a small radiator under your dashboard called the "heater core." If the heater blows cold, you may have dangerously low engine coolant (which can cause your engine to overheat), a stuck engine thermostat, a clogged heater core, or a broken blower motor. Have a mechanic check it immediately to prevent engine damage.
Yes! The cabin air filter is responsible for cleaning the air that blows through your A/C and heating vents before you breathe it in. It traps dust, pollen, exhaust fumes, and mold. If left unchanged, it becomes severely clogged, which dramatically reduces the airflow from your vents, puts extreme strain on your blower motor (causing it to fail prematurely), and causes musty odors inside the car.
