What Fresno homeowners say about Grandmark HVAC
4.8 stars across 1,200+ verified Google reviews — Fresno, Clovis, Madera, Sanger, Selma, and surrounding Fresno County cities.
Had the same AC problem fixed twice by two other Fresno HVAC companies. Grandmark found the real cause on video — a slow refrigerant leak nobody had checked. One repair. No more problems.
Eric went above and beyond explaining what was wrong with my AC unit and didn’t add extra stuff to the estimate like the other company did. Fixed the issue in minutes.
Tony and his partner found an issue created by another company that could’ve set my home on fire. Incredible job, completed in a timely manner.

Questions Fresno homeowners ask before calling
See the full Fresno HVAC FAQ → for more.
How fast can you get to my Fresno home for AC repair?
Most AC repair calls are dispatched same-day, often within 60 minutes during business hours. Book by 2 PM and we typically have a tech at your door by dinner. During peak summer season, we extend to 24/7 emergency dispatch for no-cool-air situations — see no-cool emergency service.
How much does AC repair cost in Fresno?
Our $89 diagnostic visit covers the on-site inspection, full system test, and written quote — credited in full toward your repair if you move forward. Typical repair costs run $180-$650 depending on the part and complexity, with flat-rate pricing in writing before any work begins. See signs your AC is about to fail for what to watch for before it becomes an emergency.
Should I repair or replace my old AC unit?
Generally, repair makes sense if your unit is under 10 years old and the repair cost is less than 30% of replacement. Replacement often beats repair if your AC is 12+ years old, the compressor’s failed, or you’re spending more than $1,500 per season on repairs. We show you the diagnostic on video and give you both options in writing — see installation cost guide to compare.
Do you offer financing for AC replacement in Fresno?
Yes — $0 down, 0% interest for 18 months, with same-day approval and no hard credit pull. Full AC replacement starts from $89/month with 144-month terms at 4.99% APR. See full financing terms.
Are you licensed and insured in California?
Yes. Grandmark is fully licensed (CSLB #1030917), insured, and bonded. Every tech is a W-2 employee, not a subcontractor, with a passed background check. We service all major brands including Carrier, Trane, Lennox, Rheem, Goodman, York, Bryant, and American Standard.
What’s your guarantee on AC repair work?
Every AC repair is backed by our written warranty — if the fix doesn’t hold, we return and resolve it at no additional cost. Every job ends with a completion video for your records. Fix it right, or you don’t pay.
