Frequently Asked Questions — AC Repair
Why is my AC running but not cooling?
The most common causes are low refrigerant, a dirty evaporator coil, or a failing compressor. Start with the filter — a clogged filter can restrict airflow enough to cause this. If the filter is clean, call us for a diagnostic.
Should I repair or replace my AC?
If the repair cost is more than half the cost of a new system and your unit is 10+ years old, replacement is often the better investment. We'll give you an honest answer either way — we're not going to push you into a replacement you don't need.
How long does AC repair usually take?
Most AC repairs can be completed in one visit, usually 1–3 hours depending on the issue. If a part needs to be ordered, we'll let you know the timeline upfront.
Do you service all AC brands?
Yes. We service all major residential and light commercial brands. We're also an authorized Daikin Comfort Pro dealer, so Daikin systems are a specialty.
