What brings Pomona homeowners to this job
- There is a boom or rumble when the heat kicks on Delayed ignition from dirty burners or a gas pressure problem
- The thermostat says heat but nothing turns on at all Thermostat wiring, a tripped breaker, a blown fuse on the board, or a door safety switch
- The furnace blows but the air is cold Ignition failure, flame sensor fouling, or a gas valve not opening
What we check on the unit
Common culprits are the igniter, flame sensor, pressure switch, inducer motor, limit switch, gas valve, and control board. A dirty flame sensor will light the burners and drop them seconds later, which homeowners usually describe as the heater teasing them. We also check filters, return airflow, and duct static, because a starved furnace overheats and trips its limit again and again. On attic and package equipment we inspect the flue, condensate path, and blower wheel while we are up there.
How we decide repair is the right call
We weigh the age of the furnace, the cost of the failed part, and the condition of the heat exchanger and blower. A ten year old unit with a bad igniter is a straightforward repair. A furnace with a cracked heat exchanger is a safety problem and gets shut down, not patched. If the same part has failed twice, we look upstream for the real cause, usually airflow or a wiring fault. You get both options in plain language before we touch anything.

What Pomona requires, and what it may pay back
Power here comes from Southern California Edison, gas from SoCalGas.
SCE residential efficiency rebates and SoCalGas residential rebates are the programmes worth checking. Terms move, so confirm the current ones with the utility and we will point you at the paperwork.
California Title 24, Part 6 applies to a changeout here, which normally means a permit, with HERS verification and CF2R/CF3R registration on most changeouts. City of Pomona Building and Safety Division handles them.
The federal 25C Energy Efficient Home Improvement Credit applies to qualifying equipment, and the efficiency tier it requires is worth checking before you choose a system.

My gas furnace lights then shuts off after a few seconds. What is wrong?
Usually a dirty or failing flame sensor, sometimes a flue or pressure switch problem. The furnace proves flame, loses the signal, and closes the gas valve on purpose. It is a repair visit, not a homeowner fix.
Should I keep resetting the breaker to get heat?
No. Resetting once is reasonable. If it trips again, stop and call us. Repeated trips mean a motor, board, or wiring fault that gets worse and can become a fire risk.
How soon can you get to my house in Pomona?
Most Pomona calls get a same-day or next-day slot, and during July and August heat runs we prioritise homes with no cooling at all, especially where there are older residents or infants. Call us with your cross streets and the make of your outdoor unit if you know it, and we will give you an honest arrival window instead of a vague all-day one. If your thermostat is blank, check the breaker and the batteries before we arrive, since that sometimes solves it outright.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That tells us whether to bring parts for a cooling fault or a heating fault.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and coil, refrigerant pressures, and the outdoor unit. You get told what failed and why, in plain words, before anything is replaced.
- Step 3
Repair and verify
We make the repair, then run the system and measure the results at the vents. If a part needs ordering, we say so and give you a realistic window instead of a vague promise.

Why homeowners call us
- Built for real valley heatWe work in areas where afternoons sit above 110 degrees and systems run for months without a break. That shapes how we size repairs, check capacitors and contactors, and judge whether a compressor is genuinely done.
- Attic and package unitsPlenty of homes across the region run attic air handlers or rooftop package units instead of a garage furnace and a side-yard condenser. We are used to the access, the duct runs, and the drain issues those setups bring.
- Dust and debris we expectAg dust, cottonwood fluff and grass clippings pack condenser coils and starve a system of airflow. We clean what we find and show you the difference, rather than adding refrigerant to a unit that just could not breathe.
- Heating too, not only ACFurnace repair, heat pump faults and no-heat calls get the same attention as summer work. Ignition problems, cracked or failing components and short cycling all get diagnosed before we recommend anything larger.

- Straight answersWhen a replacement beats a repair, we tell you, sometimes before we roll a truck.
