Fresno Summer Is Coming When Your HVAC Fails, Every Hour Matters — We Dispatch In Real Time.
Most Fresno HVAC companies book 2–5 days out in peak season. Grandmark’s emergency crews are dispatched from our Fresno office within 60 minutes of your call and on-site within 2 hours in most cases — 24 hours a day, 7 days a week, holidays included. No call centers. No “we’ll get back to you tomorrow.” Real techs. Real trucks. Now.
Six Situations That Can’t Wait For A Monday Morning Appointment
Not every HVAC issue is an emergency — but these six need immediate attention. If any of them apply to you right now, call (559) 245-1485 and we’ll have a licensed tech dispatched within the hour.
Complete AC System Failure — No Cooling
System runs but produces no cool air, or won’t turn on at all. Most common causes: failed capacitor, failed contactor, compressor failure, or complete refrigerant loss.
AC Running Constantly — Home Won’t Cool Down
System runs all day but can’t reach the set temperature — common in Fresno and Bakersfield when temps exceed 110°F. Causes include low refrigerant, dirty condenser coil, or an undersized system pushed past its capacity.
Ice Forming On The AC Unit
Ice on the evaporator coil or refrigerant lines signals low refrigerant or restricted airflow. Turn the system off immediately — running a frozen system damages the compressor rapidly.
AC Tripping The Circuit Breaker Repeatedly
A system that trips the breaker when it tries to start has an electrical fault — usually a failed capacitor, a failing compressor drawing excess amperage, or a wiring issue. Do not keep resetting the breaker. Each reset attempt risks damaging the compressor further.
Furnace Not Producing Heat
Furnace failures include igniter failure, gas valve issues, flame sensor fouling, and heat exchanger cracks. Carbon monoxide safety is assessed on every furnace emergency call.
Carbon Monoxide Concern — Furnace
If your CO detector has alarmed or you smell gas near your furnace — leave the building immediately and call 911 first. Once the building is cleared, call Grandmark. A cracked heat exchanger is a life-safety issue. We assess every furnace emergency call for CO risk as standard procedure.
Four Reasons Fresno Homeowners Call Grandmark First.
These are the reasons our Fresno customers call us back — and send their neighbors.
5 California Offices · Dispatched Same Day
We dispatch licensed technicians from 5 California offices covering Fresno, Sacramento, Bakersfield, Modesto, and Visalia. Your call is routed to the nearest office with a real tech on standby — not a call center that schedules you for Monday.
Parts On Every Truck — Most Fixed Same Visit
Common failure parts — capacitors, contactors, igniters, flame sensors, blower motors, control boards — are stocked on every truck. 85% of emergency HVAC repairs in California are completed on the first visit.
Carbon Monoxide Safety On Every Furnace Call
A cracked heat exchanger can allow carbon monoxide into living spaces — a life-safety issue with no symptoms until it’s too late. We assess CO risk on every furnace emergency call as standard procedure. Not optional. Not an add-on.

“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.”
Carlos V.

★★★★★
“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.”
Maria T.

★★★★★
“They replaced our AC and sealed the ducts at the same time. Didn’t know that was even possible with one company. House is cooler than it’s been in years and I have video proof of every step.”
