This Is Exactly
How We Diagnose.
Meter in hand. 240V at the motor. 24V from the board. Bad ECM motor — diagnosed on camera before we quote anything. This is what every Grandmark job looks like.
“I watched the whole video before they even quoted me. I’ve never had a contractor do that. That’s the only way I’ll ever hire again.”

We’ve Seen It Before.
Same-day repair across Central Valley. We diagnose first, quote honest, and show you proof of every fix before you pay.
Low refrigerant, dirty coils, or compressor failure — the most common call we get in Fresno, Visalia, and Clovis summers. We diagnose the exact cause on video before touching anything.
Blown capacitors, tripped breakers, electrical faults — our techs find the root cause fast without guesswork. Most electrical issues resolved same day.
Banging, grinding, burning — these signals mean something is wrong. We identify and fix it before a repair becomes a full replacement. Don’t wait on this one.
An inefficient system works harder and costs you more every month. In a Central Valley summer, that adds up fast. We run an efficiency diagnostic and fix what’s causing the spike.
AC dies at 10pm in Los Banos, Tulare, or Hanford? We answer around the clock, 365 days a year. Same-day emergency service across all of Central Valley — no extra charge for after-hours calls.
Low refrigerant is a symptom, not the problem. We find the leak, fix it properly, then recharge to manufacturer spec. Topping off without fixing the leak is money wasted.
We Show You What’s Wrong
Before We Quote.
Most HVAC companies tell you what they found. Grandmark shows you on video — before a single dollar is quoted. No surprises. No overselling.
Tell us what your AC is doing. We cover all of Central Valley — Fresno, Clovis, Visalia, Tulare, Los Banos, Merced, Madera and everything in between. Emergency calls answered 24/7.
Our tech uses digital gauges and inspection cameras to find the exact issue. You watch the diagnostic on video before we say anything. No guessing, no padding.
We tell you what it actually needs. If a repair makes sense, we fix it. If replacement is smarter, we show you exactly why — on camera. No pressure either way.
Job done same day in most cases. Post-repair video sent to you before you sign off. Cold air tonight.

1,200+ Homeowners Who
Finally Got It Fixed Right
“AC went out at 9pm on a Tuesday — 104 degrees in Fresno. Called Grandmark and they had someone out by 8am the next morning. Diagnosed on video, showed me exactly what failed. Fixed same visit. Best experience I’ve had with any contractor.”
“Three companies told me I needed a full replacement. Grandmark ran their video diagnostic and found a bad capacitor — $180 fix. Sent me the video. I watched the whole thing. That honesty is rare. Won’t call anyone else.”
“Called about an emergency repair in Los Banos on a Saturday. They came out, video-diagnosed the issue, quoted me before touching anything, and had it fixed the same day. Didn’t try to upsell me once. This is the company.”
