AC & Heating Service in Irvine, CA
Irvine is the city where we've filmed more jobs than any other. Much of the housing is newer, with the furnace and coil up in the attic, and that shapes the work: tight installs, coil leaks on systems under ten years old, and furnace faults that trace back to something small.
What we see in Irvine homes
Newer homes still need replacements
One eight-year-old home had its evaporator coil leak one year and its outdoor unit the next. We replaced both.
Attic equipment with no room to work
A furnace and coil replacement took nine hours because of the clearance around the unit.
Furnace problems that start small
A high-efficiency furnace locked out because its filter hadn't been changed in two years. Another had a failed control board.
Faults left over from construction
We found a furnace flue that had been sealed off since the house was built, venting into the attic for seven or eight years, and a new-build breaker that kept tripping the AC.
Warranty claims handled for you
On a 2020 unit we filed the manufacturer claim for the owner, which saved them $900 on a new motor.

5-ton heating and cooling replacement
5-ton heating and cooling replacement in Irvine. This homeowner came to us through a neighbor we had already worked for. A referral from a past customer is the best proof that the workmanship and attention to detail hold up.
New-build AC that kept tripping the breaker
A new home in Irvine's Great Park whose AC kept tripping. The day before, the company that installed the system added a hard-start kit. It lowered the start-up current, but the breaker tripped again ten minutes after they left. With a thermal camera we found the fault was the breaker itself: one point in the panel was running over 100°F while the AC drew a normal 12 amps. We replaced it and re-terminated the wiring. After ten minutes of running, that spot read about 91°F, the same as the rest of the panel.

Eight-year-old home: leaking coil and outdoor unit replaced
This Irvine home is only eight years old, but the evaporator coil leaked last year and the outdoor unit started leaking this year, so we replaced both. The old equipment was Carrier. The brand isn't really the issue; any make can develop a leak. The attic was very tight to work in. New coil installed, ductwork reconnected, system running normally.
Furnace and coil in a near-impossible attic
One of the hardest install locations we've had. The indoor unit sat in the attic with almost no clearance around it. Once the old evaporator was out you could see oil across the whole drain pan, the sign of a refrigerant leak. Nine hours of work to get the new equipment in and connected. Everything is running normally.
Evaporator coil replacement

4-ton heating and cooling replacement
4-ton heating and cooling replacement in Irvine. The old furnace and evaporator came out and new ones went in. The old evaporator was badly corroded.
Furnace flue sealed off since the house was built
The tenant said the heater did nothing when switched on. In the attic we found the furnace's exhaust flue had been sealed off when the house was built, seven or eight years earlier. Every time the furnace ran, the combustion gases emptied into the attic, and the moisture had rotted the surrounding wood. Testing it for a few minutes was enough to feel sick. The attic was sealed from the living space, which is the only reason those gases hadn't reached the rooms. We shut off the gas and had the owner call a roofing company.
Carrier high-efficiency furnace locked out by a dirty filter
The furnace wouldn't respond at all. It had overheated and the control board had locked out. The cause was a filter that hadn't been changed in two years.
Repairing a 20-year-old furnace near UCI
Third repair of the day, in the older neighborhoods near UCI. The furnace was about 20 years old. Older equipment is simpler by design, which makes it easier to repair.
Carrier furnace with a failed control board
The second Carrier furnace we repaired in the same Irvine community that day. The control board had failed: it cut power to the heating element the moment it was applied.
Warranty motor replacement on a 2020 Carrier
A 2020 Carrier unit with a failed motor. We filed the manufacturer warranty claim for the homeowner, which saved them $900 on the new motor. A licensed contractor can file that claim for you, and you get an original factory part.
