Car AC repair and heating service in Gresham, OR
All About Automotive diagnoses and repairs car AC and heating systems for all makes and models. Whether your AC is blowing warm air in summer or your heater is leaving you cold in January, we find the actual cause and fix it right — not just recharge and send you on your way.
What we service
AC and heating repairs we perform
Your vehicle's AC and heating system share the same basic infrastructure: refrigerant lines, the blower motor, and the controls that decide where conditioned air goes. Problems on either the cooling or heating side often trace back to the same components. Here is what we handle:
AC recharge and leak repair
We recover the existing refrigerant, pressure-test the system to locate any leaks, repair the leak source, and recharge to the manufacturer's specification. A recharge without a leak check is a short-term fix that will leave you hot again next summer.
Compressor and condenser service
The compressor pressurizes the refrigerant; the condenser dissipates the heat. A seized compressor or a bent-fin condenser (common after a front-end impact or road debris) will kill your cooling entirely. We replace both components and flush the system when needed.
Heater core and coolant system
The heater core is a small radiator behind your dashboard that uses hot engine coolant to warm the cabin air. A leaking heater core can fog your windshield from the inside or leave a sweet-smelling film on the glass. We also service the thermostat and coolant system that feeds it.
Blend door and climate control
Blend doors control how much hot or cold air mixes before it reaches the vents. A failed blend door actuator is a common cause of temperature control that will not respond — the temperature knob turns but the air stays hot or cold regardless of the setting.
Cabin air filter
A clogged cabin air filter reduces airflow through the entire system, making your AC and heat less effective and putting extra load on the blower motor. We check and replace it as part of any HVAC inspection.
Warning signs
Signs your AC or heat needs service
Gresham summers get warm and winters get cold. These are the symptoms that tell us the climate system needs attention before you are stuck in either extreme:
- AC blows warm or lukewarm air — usually low refrigerant from a leak or a compressor that is not engaging.
- No heat or slow warm-up in winter — often a stuck-open thermostat, low coolant, or a partially blocked heater core.
- Musty or moldy smell from vents — moisture is collecting in the evaporator housing. A clogged drain line or a dirty cabin filter is usually the cause.
- Unusual noise when AC is on — a rattling or squealing when the compressor engages points to a worn compressor clutch or failing bearings.
- Windshield will not defog — if the defroster is on but the windshield fogs from the inside, suspect a leaking heater core or a blend door sending air the wrong direction.
- Moisture on the passenger floor — a heater core leak can drip coolant onto the floor mat before any other symptom appears.
Any of these symptoms are worth a quick inspection before the problem gets worse. Book a time or call us at (503) 465-2926.
Common questions
AC and heating FAQ
Why is my car AC blowing warm air in Gresham?
Warm air from a car AC usually means the system is low on refrigerant due to a leak, or the compressor is not engaging. Less common causes include a failed condenser, a clogged expansion valve, or an electrical fault in the compressor clutch circuit. A quick inspection tells us which one — do not keep adding refrigerant without finding and fixing the leak first.
How often should I recharge my car's AC?
A properly sealed AC system should not need regular recharges. If yours needs refrigerant every summer, there is a leak somewhere. Refrigerant does not get used up like fuel — it circulates in a closed loop. We find and repair the leak, then recharge to the correct spec. Topping off without fixing the leak wastes money and can harm the environment.
Why does my car heat take so long to warm up?
Slow heat-up usually means the engine coolant is not reaching normal operating temperature quickly enough — often a stuck-open thermostat. Other causes include a low coolant level, a partially blocked heater core, or a blend door that is not directing airflow correctly. A thermostat replacement is a relatively simple fix that makes a noticeable difference in winter.
How much does car AC repair cost in Gresham, OR?
Cost depends on what is wrong. A refrigerant recharge after a leak repair runs less than a compressor replacement. We give you a written estimate before any work starts. Call us at (503) 465-2926 or book online for a current price — we work on all makes and models and do not charge just to look at it without knowing what we are dealing with.
