AC Repair FAQs

How fast can you respond when my AC stops cooling?

Same-day in most cases. We answer the phone 24/7 across the Denver metro and can usually reach your home within 2-4 hours during emergencies. During peak summer heat events response can run slightly longer.

Will I need a new AC unit if it's blowing warm air?

Probably not. The most common causes are low refrigerant, a failed capacitor, or a frozen coil from a dirty filter — all repairs, not replacements. We diagnose first and only recommend replacement when the math actually supports it.

How much does AC repair typically cost in Denver?

Common AC repairs run $150-$600 depending on the part. Capacitors and contactors are on the low end; refrigerant leaks and compressor work are higher. You get a flat-rate price before we start — no hourly surprises.

Do you charge a service call fee?

Yes — a small diagnostic fee covers the trip and first-hour evaluation. We always tell you the fee on the phone before heading out, and if you proceed with the recommended repair we waive most of it.
