Real feedback from homeowners and business owners who called us first.
“Our AC died at 8pm during a heat wave and First Call had a technician at the house before 10. He showed me the burned-out capacitor, quoted the price before touching anything, and we had cold air the same night. No after-hours surcharge either. — Potrero”
“Woke up to no heat with a newborn in the house. They moved us to the front of the line, found a cracked ignitor, and had the furnace running in under an hour. Honest, fast, and they actually explained what went wrong. — Potrero”
“Three companies quoted us a new system. First Call was the only one that measured airflow and did a real load calculation instead of guessing. The new unit is quieter and our summer bill dropped noticeably. — Potrero”

☎ (209) 309-1834AC not cooling, blowing warm air, leaking water, tripping the breaker or making noise? We diagnose and repair every brand of central air, heat pump and mini split.
Repair bills stacking up? We size, quote and install high-efficiency air conditioning systems with real load calculations and airflow testing — not guesswork.
No heat, cold air from the vents, a furnace that won't ignite, or a system that short cycles — we repair gas furnaces, electric heat, boilers, heat pumps and wall units.
Every gas and electric furnace brand serviced, with combustion and carbon monoxide safety testing included on every visit.
A properly installed furnace is quieter, safer and cheaper to run. We handle sizing, venting, ductwork, gas lines and permits.
Heat pumps run year-round, so they fail more often. We repair reversing valves, defrost boards, charge problems and auxiliary heat faults.
Heat waves and cold snaps don't keep business hours. Our dispatch line is staffed 24 hours a day, 7 days a week, holidays included.
Most emergency breakdowns we see were preventable. A 21-point seasonal tune-up keeps capacity high and utility bills low.
Ductless systems deliver room-by-room comfort with no duct losses — perfect for older homes, additions, ADUs and apartments.
A miswired thermostat can look exactly like a dead AC or furnace. We install, wire and program smart thermostats correctly the first time.
Leaky, dirty ducts waste up to 30% of the air you paid to heat and cool. Cleaning, sealing and filtration upgrades fix comfort problems fast.
Downtime costs money. We service rooftop package units, split systems and light commercial equipment on your schedule, including after hours.
