FREE AC Performance Check
Not sure what's wrong with your AC? Find out at no cost.
Warm air, weak airflow, strange noises or a musty smell can all point to different problems — a low charge, a leak, a failing compressor, or an electrical fault. Guessing gets expensive.
Our AC Performance Check tells you exactly what's going on, and it's FREE.
What's included, at no charge:
- A/C system performance check
- Leak detection check
- Compressor and condenser inspection
- Electrical component check (fans, sensors)
- Cabin filter inspection
- A clear explanation of what we found and what it would cost to fix
No obligation. If a repair is needed, we'll quote it first — you decide whether to go ahead. Any parts, refrigerant or repair work are quoted separately.
Backed by a 30-Day Warranty
All AC repair work at Auto Worx is covered by a 30-day warranty. If something isn't right, bring it back.

Auto AC Repair — Common Questions
How much does auto AC repair cost in Guam?
It depends on what's wrong — a refrigerant recharge costs far less than a compressor replacement. Our AC Performance Check is free, so you'll know exactly what's needed and what it costs before committing to anything.
Is the AC check really free?
Yes. The performance check and diagnosis cost you nothing. If a repair is needed, we quote it first and you decide. Parts, refrigerant and repair work are quoted separately.
Do you warranty your AC repairs?
Yes. All AC repair work at Auto Worx is backed by a 30-day warranty. If something isn't right, bring it back and we'll take care of it.
Why is my car AC blowing warm air?
The most common causes are low refrigerant from a leak, a failing compressor, a blocked condenser, or an electrical fault in the fans or sensors. The free check tells you which.
Why does my AC smell musty?
Usually moisture and buildup on the evaporator, or a dirty cabin air filter — very common in Guam's humidity. Both are straightforward to address.
Do you service both R134a and R1234yf?
Yes. We support both refrigerant types.
