Fast, Reliable Furnace Repair Across Pomona
Furnace repair in Pomona typically runs $150 – $700, and most jobs are completed the same day we arrive. If your heat is out on a cold inland-valley night, you don’t need a callback window. You need a technician who shows up, diagnoses the problem, puts the price in writing, and fixes it. Dalton Heating & Air answers the phone 24/7 with a live person, and our Pomona crews arrive inside the stated window, every call. Call (361) 306-9515 when the furnace quits.
Why Dalton Heating & Air Is Pomona’s Preferred Furnace Repair Company
Pomona homeowners call us because our work comes with terms most companies won’t put in writing. The Garrison Standard, in place since 2003, means every repair gets a written price before any work starts and a written guarantee that covers the repair for a full year. If the part fails or the fix doesn’t hold, we return at no charge. No fine print, no warranty upsell. That’s the standard.
Our technicians are background-checked and uniformed, so you know who’s walking through the door before they arrive. They carry parts for Trane, Lennox, Goodman, and Rheem furnaces in the van, which means fewer follow-up trips. And when a Pomona homeowner calls at 2 a.m. with no heat, they get a person on the line, not a voicemail queue. Marco Benitez leads our team and holds every tech to The Garrison Code: show up on time, price in writing, do the job by the book, leave the site clean.
Boiler Repair in Pomona
Boiler repair in Pomona usually runs $150 – $700, depending on the failing component. Older homes in neighborhoods like Lincoln Park and the stretch of Holt Avenue built before 1970 still run hydronic heat, and when the circulator pump or expansion tank fails, you’ll hear knocking in the pipes or notice cold spots in rooms that used to heat evenly. We diagnose the exact part, quote the repair in writing, and stand behind it for a year.
If a boiler loses pressure repeatedly or the burner fires but water never gets hot, homeowners often assume the whole unit is dead. That’s rarely true. Most repairs are a single component: a failing zone valve, a waterlogged expansion tank, or a thermocouple. We show you the failed part before replacing it.
Common Pomona Boiler Failures
Circulator pump failures are common in Pomona’s older ranch homes, especially after a summer of sitting idle. Sediment buildup in the heat exchanger, which lowers efficiency and causes banging, is another frequent diagnosis. Both are repairable without replacing the boiler.
Repair or Replace a Boiler in Pomona
If your boiler is 25 years old and the heat exchanger has cracked, replacement starts to make sense. But if the unit is under 15 years old and the issue is a $200 part, repair is the clear call. We walk through the math with the actual numbers, not pressure.
Gas Furnace Repair in Pomona
Gas furnace repair in Pomona typically lands between $150 and $700. The most common call we get is a furnace that fires up, runs for a minute or two, then locks out. In Pomona’s older tract homes, that’s frequently a failing hot-surface igniter or a dirty flame sensor, both of which are straightforward fixes. But in some units from the 1990s, it’s a cracked heat exchanger, and that changes the conversation to repair-versus-replace.
Ignition and Flame Sensor Repairs
Pomona’s dry inland air and valley dust coat flame sensors faster than coastal areas. The furnace tries to fire, doesn’t sense the flame, and shuts down as a safety measure. We clean or replace the sensor, confirm the flame signal, and test multiple cycles before leaving.
Heat Exchanger Inspection Before Every Repair
Every gas furnace diagnostic at a Pomona home includes a visual inspection of the heat exchanger. A crack lets combustion gases into the home’s air supply, and that’s a safety issue, not a comfort issue. If we find a crack, we show it to you on camera and explain your options plainly.
Trusted Brands We Service in Pomona
Our technicians are factory-trained and service nine major residential HVAC brands, but on Pomona’s streets we see more Trane, Lennox, Goodman, and Rheem furnaces than anything else. That means our vans carry the igniters, flame sensors, capacitors, and gas valves for those brands, so most repairs are done on the first visit. No “we’ll order the part and call you in a week.” If you’re not sure what brand sits in your garage or attic closet, the tech will know the moment they pull the panel.
Common Furnace Repair Problems We See in Pomona Homes
- Short-cycling from an oversized furnace. Many of Pomona’s 1950s and 1960s tract homes got oversized units because a contractor sized by square footage alone. A furnace that fires, runs three minutes, and shuts off is usually too big for the space, and a load calculation tells us what should actually be there.
- Cracked heat exchangers on 1990s-era units. Furnaces that cycled hard through Pomona’s 100°F summers and cold winter nights develop metal fatigue at the exchanger seams. We scope these on every call because a crack is a carbon monoxide risk no homeowner should ignore.
- Ignition and flame-sensor failures on older Carrier, Lennox, and Goodman furnaces. Valley dust and dry winter air accelerate sensor fouling here. The fix is usually a cleaning or a $150 – $250 part replacement, not a new furnace.
- Blower motor and capacitor failures that show up as weak heat. A furnace that runs but barely pushes warm air often has a failing blower motor or run capacitor. We test the capacitor under load rather than guessing, because misdiagnosing this as a thermostat problem wastes your money.

FAQs About Furnace Repair in Pomona
It’s usually a repair. The most common causes in Pomona homes are a dirty flame sensor, a failing hot-surface igniter, or a clogged condensate line, and all three run well under $700. The exception is a cracked heat exchanger, which we scope on camera before talking replacement. Call (361) 306-9515 and we’ll tell you which one it is.
For many Pomona homes, a dual-fuel setup or a high-efficiency heat pump makes more sense than another straight gas furnace. Pomona swings from triple-digit summers to low-40s winter nights, and a heat pump handles both. Add South Coast AQMD’s NOx rules and the math often favors a heat pump on replacement. We run the load calculation and show you the numbers.
Most furnace repairs in Pomona run $150 – $700, with the final number depending on the failed part. A flame sensor or igniter is at the low end; a gas valve or blower motor is at the high end. You get the exact price in writing before any work starts. Call (361) 306-9515 for a free estimate.
That’s almost always accumulated dust burning off the heat exchanger after months of sitting idle during Pomona’s long cooling season. It should clear within 10 – 15 minutes. If the smell persists or you notice a gas odor, shut the furnace off and call us at (361) 306-9515 immediately.
Yes. The South Coast AQMD’s NOx limits mean some older furnace models can no longer be installed in Pomona, even as a direct replacement. When we quote a replacement, we only specify furnaces that meet current regional rules, and we’ll explain in plain terms what that means for your equipment choice.
Why Pomona’s Climate Changes the Repair Math
Pomona sits in the San Gabriel Valley’s inland basin, where winter nights routinely drop 15 – 20°F below coastal LA and summer days push past 100°F. That swing matters for furnaces. A unit sized for mild coastal winters works too hard in Pomona. South Coast AQMD’s NOx rules add another layer: many homeowners looking at a failing 20-year-old furnace are also looking at a compliance question. In a lot of cases, replacing a dead gas furnace with a high-efficiency heat pump or dual-fuel system pencils out better here than a straight gas swap. We run the load calculation before we ever quote a replacement, so you’re not guessing.
A couple of winters back, our tech was called to a 1960s ranch house off Towne Avenue near Ganesha Park. The Carrier gas furnace would fire, run 90 seconds, then lock out. The homeowner braced for a replacement quote. The real fault was a failing hot-surface igniter plus a cracked heat exchanger the old unit had been hiding for years. We showed the crack on camera, ran a load calculation, and walked them through repair-versus-replace with actual numbers. They replaced the furnace with a unit sized for their actual home, not the oversized unit that had been short-cycling for years.
If your furnace is acting up in Pomona, call (361) 306-9515. We’ll send a technician who shows up inside the window, diagnoses the problem on the spot, and puts every price in writing before any work begins.
