Frequently Asked Questions

Why is my AC blowing warm air?

Common causes include low refrigerant, a dirty air filter, frozen evaporator coils, or a faulty compressor. Our technicians can diagnose the exact issue.

How much does AC repair typically cost?

AC repairs typically range from $89-$500+ depending on the issue. We provide upfront pricing before any work begins so there are no surprises.

Should I repair or replace my AC unit?

Generally, if your unit is over 10-15 years old and repairs exceed 50% of replacement cost, replacement is often more economical in the long run.

How long does an AC repair take?

Most common repairs are completed in 1-2 hours. More complex issues or those requiring parts may take longer, but we always communicate timelines clearly.
