That’s where we come in—with efficient, honest service that gets your AC or heat working the way it should.
Your Vehicle’s Climate Control System Matters
Your car’s heating and cooling system does more than keep you comfortable. It also affects safety, visibility, and engine performance. If your AC or heater isn’t working properly, it could be a sign of deeper issues that shouldn’t be ignored.
Signs your system needs service:
-
AC blowing warm or inconsistent air
-
Heater takes too long to warm up
-
Musty or moldy smells from vents
-
Loud noises when AC or heat is running
-
Windows fogging up due to poor defrost function
-
Cabin not cooling or heating evenly
-
Clicking, hissing, or rattling sounds under the dash
If you’ve noticed any of these, it’s time to stop by Arthur’s Automotive. We’ll find the source of the problem and fix it right—the first time.

What Happens During an Auto AC Recharge?
A common issue we see in Portland is vehicles that blow lukewarm air when the AC is on. In most cases, this means it’s time for an auto AC recharge. Over time, refrigerant naturally escapes or degrades, reducing your AC’s ability to cool the cabin.
Here’s what we do during a recharge:
-
Evacuate old refrigerant and moisture from the system
-
Perform a vacuum leak test to check for leaks
-
Refill with the correct amount and type of refrigerant
-
Check AC pressure, temperature, and airflow performance
-
Inspect AC compressor, belts, and sensors
Recharging your system can restore full cooling power and help prevent premature compressor failure or expensive repairs down the line.
Understanding Auto Heat Service
On the other end of the spectrum, Portland’s winters mean you need a fully functional heater. A failing heating system can be more than uncomfortable—it can be dangerous if your windows won’t defrost properly.
Common issues we fix with auto heat service:
-
Failing thermostats that prevent proper engine warming
-
Heater core blockages or leaks
-
Blower motor malfunctions
-
Faulty blend doors or actuators
-
Weak or no airflow from vents
-
Electrical or control system problems
Don’t wait until you’re driving in the cold without heat—let us keep your car cozy when the temperature drops.
Common Questions About AC & Heat Repair in Portland
How often should I get my AC system checked?
At least once a year. Even if it seems fine, small leaks or performance drops can become bigger issues over time.
What if my AC works sometimes but not always?
That’s often a sign of a failing compressor, a sensor issue, or a refrigerant imbalance. We’ll run a full diagnostic to pinpoint it.
Why does my car smell when I turn on the heat or AC?
You may have mold buildup in your system or a clogged cabin filter. We can clean the system and replace filters as needed.
Is it safe to recharge my AC at home with a DIY kit?
Not really. Overcharging or using the wrong refrigerant can damage your system. It’s best left to professionals with the right tools.
Can a bad heater affect my defrost system?
Yes. The defrost relies on warm air being directed toward the windshield. A faulty heater means poor visibility and longer warm-up times.
What refrigerant does my car use?
Most modern vehicles use R-134a or the newer R-1234yf. We service both and always follow manufacturer specifications.
