What “no AC” actually means in a Central Valley summer
A dead AC system in a 108°F Fresno afternoon isn’t an inconvenience — it’s a real health risk, especially for kids, elderly household members, and pets. Heat-related illness can set in within hours in a home with no cooling. That’s why a no-cool call gets treated differently than a routine repair.
Priority dispatch
No-cool calls jump the queue ahead of routine maintenance and non-urgent repairs. Most calls get a tech out same-day, often within a few hours.
Roof-mounted units, roofing expertise
Most Fresno AC units sit on the roof, not the ground. We’re the rare HVAC company that also employs licensed roofers — so nobody’s guessing about the deck your unit sits on.
Real diagnostics, not a guess
Our diagnostic-first approach finds the actual failure — capacitor, refrigerant leak, compressor, electrical — documented on video before any repair begins.
While you’re waiting for the tech
Check the basics first
Confirm the thermostat has power and is set to cool, and check your breaker panel for a tripped switch — it’s a five-minute check that occasionally solves it before we even arrive.
Call and describe the symptoms
Warm air from vents, unit not turning on at all, unusual noise, or water pooling — tell us exactly what’s happening so we bring the right parts on the first visit.
We diagnose on-site, on video
A licensed technician runs a full system check and shows you the actual problem before quoting a repair — flat-rate pricing in writing, no surprise add-ons.
The only Fresno HVAC company that’s also a licensed roofer
Most Fresno AC units sit on the roof, which means most HVAC-only companies are guessing when it comes to the roof penetrations, flashing, and mounting your system depends on. Grandmark is different — we’re GAF Master Elite roofers and BOSCH authorized HVAC technicians under one company. When we service a roof-mounted unit, the seal around it gets handled by someone who actually roofs for a living, not caulked by a tech on his way out the door.
What Fresno homeowners say about emergency service
4.8 stars across 1,200+ verified Google reviews — Fresno, Clovis, Madera, Sanger, Selma, and surrounding Fresno County cities.
Tony and his partner did an incredible job and completed the work in a timely manner. They found an issue created by another company that could’ve set my home on fire.
Three companies gave me quotes without even looking at the system. Grandmark ran a diagnostic and found the real issue. Saved me over $2,000 and my AC has been perfect ever since.
AC went out on a Saturday in July. Grandmark came out same day, diagnosed it on video, and had it fixed within two hours. Every other company told me the earliest was Tuesday.
We’ll respond in 20 minutes or less
Tell us your AC is completely down and we’ll prioritize your call. During business hours, that’s typically within 20 minutes; during peak summer season, we extend to 24/7 emergency dispatch.
No-cool emergency FAQ
How fast can you get here if my AC is completely dead?
No-cool calls get priority dispatch ahead of routine maintenance. Most calls are handled same-day, often within a few hours during business hours. During peak summer season, we extend to 24/7 emergency dispatch for no-cool situations.
What usually causes a complete AC failure?
The most common causes are a failed capacitor, a tripped breaker or electrical issue, a refrigerant leak causing the compressor to shut down for protection, or a failed contactor. We diagnose the actual cause on-site rather than guessing.
Is it dangerous to be without AC in a Fresno summer?
Yes, particularly for children, elderly household members, and pets. Indoor temperatures can climb dangerously fast without cooling during a 105-110°F day. If anyone in your home is at heightened risk, treat a no-cool situation as urgent and call immediately.
What does emergency AC repair cost?
Our $89 diagnostic visit is credited in full toward your repair. Typical repair costs run $180-$650 depending on the part and complexity, with a flat-rate quote in writing before any work begins — no emergency surcharge games.
Why does Grandmark handle roof-mounted units differently?
Most Fresno AC units are roof-mounted, but most HVAC companies aren’t roofers and don’t fully understand the roof penetrations and flashing their equipment depends on. Grandmark is GAF Master Elite certified as roofers and BOSCH authorized as HVAC technicians — the same company handles both, so nothing gets missed at the seam between the two trades.
