Furnace repair in Kirby, TX typically runs $150 – $700 depending on the part that failed, and most no-heat calls can be diagnosed and fixed in a single visit. That’s the honest range you should expect from any reputable shop, and it’s what Dalton Heating & Air puts in writing before we touch a single component. If your furnace is down in Kirby, call (361) 306-9515 and you’ll get a live person, not a voicemail queue.

Why Dalton Heating & Air Is Kirby’s Preferred Furnace Repair Company
Kirby homeowners call us because we show up inside the stated window and we put the price in writing before any work begins. That’s not a marketing line. It’s the Garrison Code, the operating standard every Dalton technician follows since the company was founded in 2003. Kirby residents have told us the same story for years: a furnace guy showed up three hours late, quoted one number on the phone, then tried to double it at the door. We don’t work that way.
Marco Benitez leads our team under The Garrison Standard, which means every repair includes a written guarantee for a full year. If the repair fails inside that window, we return at no charge. That’s the 365-Day Done Right Promise, and it applies to every furnace repair we complete in Kirby. Our technicians are background-checked, uniformed, and factory-trained to service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. When you book a call, you’ll know exactly who’s coming to your door.
Heating Repair in Kirby
Heating Repair in Kirby means diagnosing a no-heat or low-heat condition on a forced-air furnace and getting it running safely again, usually the same day. Kirby’s older homes present a specific pattern: many were built with undersized return-air pathways, and when those ducts choke airflow, the furnace works harder than it should. That strain shows up as blower motor failures, cracked heat exchangers, and short-cycling. We start every heating repair with a static pressure test before quoting any work, because in Kirby, the airflow reading often tells us more than the furnace itself does.
Static Pressure and Airflow Diagnosis
A heating repair that skips static pressure testing is guessing. In Kirby’s mid-century ranch homes, we regularly see total external static pressure above 0.8 inches of water column, which is well outside the manufacturer’s spec. The furnace is not the only problem: the ductwork is strangling it. When we find that, we explain what the reading means and give you a repair plan that addresses the furnace first and the airflow second, with prices for both.
Same-Day No-Heat Service
When your furnace quits during a cold snap in Kirby, you don’t have a week to wait. We dispatch same-day for genuine no-heat calls across Kirby, and our techs arrive with common parts on the truck: ignitors, flame sensors, pressure switches, gas valves, limit switches, and blower motors. Most heating repairs in Kirby run $150 – $700 in parts and labor, and you’ll approve the written price before we start.
Boiler Repair in Kirby
Boiler Repair in Kirby is less common than forced-air furnace work, but plenty of older homes in neighborhoods like the ones off Old Seguin Road still run hydronic heating. A boiler that loses pressure, short-cycles, or stops producing heat is a different animal than a furnace: the loop is filled with water, the heat exchanger runs hotter, and a failed circulator pump can mimic a low-water cutoff problem. Like furnace repair, boiler repair in Kirby generally falls in the $150 – $700 range depending on the component.
Circulator Pumps and Zone Valves
A boiler that makes heat but won’t push it through the house usually has a stuck circulator pump or a failed zone valve. We test amperage draw on the circulator, check the relay, and inspect the zone valve’s end switch before quoting the repair. No guesswork.
Pressure and Expansion Tank Checks
Kirby’s older boiler systems often have expansion tanks that have waterlogged over decades. That drives pressure spikes and can trip the relief valve. We test the tank, check the fill valve and pressure-reducing valve, and give you a written price to replace what’s failed.
Trusted Brands We Service in Kirby
Dalton Heating & Air repairs furnaces and boilers from every major residential manufacturer, and our Kirby trucks carry parts for Goodman, Rheem, York, and Daikin systems, along with five other factory brands. That matters when your home has a 20-year-old Goodman furnace and the supply house nearest Kirby doesn’t stock the inducer motor until Thursday. We keep local parts availability high so Kirby customers get faster turnarounds. Factory training on all nine brands means we’re not learning on your dime.
Common Furnace Repair Problems We See in Kirby Homes
- Cracked heat exchangers: Kirby’s 1950s – 1980s furnace closets often have undersized return-air pathways, and years of operating against high static pressure cause metal fatigue. A cracked heat exchanger is a carbon monoxide risk, so we test with a combustion analyzer before we condemn or repair anything.
- Blower motor failures that look like ignition problems: A furnace that fires the burners but never pushes warm air through the registers is often a dying blower motor, not a control board or ignitor. We confirm with an amp-draw test before quoting the repair.
- Flame sensor and ignitor faults from dusty closet retrofits: Many Kirby homes had the furnace closet enclosed as part of a remodel without adding make-up air. The burners pull combustion air from the living space, and that pulls in lint and dust that coats the flame sensor.
- High-limit trips from static pressure: When return air is restricted, the furnace overheats and the high-limit switch shuts it down. The furnace short-cycles, then restarts, then shuts down again. The fix is an airflow correction, not a new limit switch.

FAQs About Furnace Repair in Kirby
Check the return-air side of your system first, because Kirby’s mid-century homes frequently have undersized return pathways that raise static pressure and trip the high-limit switch. A dirty filter makes it worse, so replace that before calling. If the short-cycling continues, call (361) 306-9515 and ask for a static pressure test along with the diagnostic. We include that on no-heat calls in Kirby, because airflow is usually the original problem.
A cracked heat exchanger usually shows up as a furnace that runs, shuts down early, or sets off a carbon monoxide detector, but a visual crack is often invisible without a combustion analyzer. We test flue gases and carbon monoxide levels on every furnace repair in Kirby. If the exchanger is cracked on a furnace older than 15 years, the repair rarely makes sense: the part cost and labor often exceed half the price of a properly sized replacement. We’ll show you the numbers either way and let you decide.
A load calculation tells you whether your furnace is sized right for your actual house, not for a rule of thumb. In Kirby, many older homes had furnaces installed before tight ducts and added insulation changed the heat load. We recently serviced a 1970s ranch near Kirby Middle School where the load calculation showed the existing furnace was oversized, which explained why the blower motor failed and the heat exchanger cracked. The load calc changed the math: replacing with a correctly matched system made more sense than repairing a unit that was the wrong size from the start.
SEER2 is the updated efficiency rating for cooling, and it applies to the heat pump side of a new system, not the gas furnace burner itself. What matters for your Kirby heating bill is the furnace’s AFUE rating: a 95% AFUE furnace sends 95 cents of every gas dollar into your ductwork, where a 70% AFUE unit wastes 30 cents. If you’re replacing an old furnace in Kirby, a higher AFUE and a matched coil sized from a load calculation will cut your actual winter gas use. We show you the expected operating cost difference before you sign anything.
We service both. Boiler repair in Kirby is a smaller part of our call volume, but our techs handle hydronic systems, circulator pumps, zone valves, expansion tanks, and pressure controls. If your older Kirby home heats with radiators or baseboards and the system won’t hold pressure or push heat, call (361) 306-9515 and ask for a boiler diagnostic. The price range is the same as furnace repair: $150 – $700.
