Call (817) 402-2972

We’ve worked on enough houses near Southwestern Adventist University to know that Keene’s mid-century housing stock hides problems a quick part swap won’t fix. Original ductwork, undersized return plenums, and electrical panels from the Adventist community build-out often turn a simple no-heat call into a system-and-infrastructure conversation. That’s why our Furnace Repair team starts with a full diagnostic, not a guess.

Why Coldharbour Heating & Air Is Keene’s Preferred Furnace Repair Company

We’re independently owned and operated, founded in 2003 as part of the Kingswell network of HVAC businesses. Every technician who walks through your door in Keene is background-checked, uniformed, and trained to service nine major residential brands including Rheem, York, and Daikin. We don’t send a salesperson in a technician’s uniform.

Our 365-Day Done Right Promise means every repair comes with a written guarantee. If the same part or the same problem comes back inside a full year, we return and correct it at no charge. No argument, no additional trip fee. The guarantee is written down before the technician leaves, not offered as a verbal afterthought.

Phones are answered by a live person around the clock, every day of the year. No voicemail trees, no “call back during business hours” when your furnace quits on a Sunday night in January. We give you a firm arrival window, and we show up in it. That’s The Kingswell Way.

Victor Mancini leads our operation, and he’s built the company on a simple idea: say the price before the work starts, show up when promised, leave the place cleaner than you found it, put the guarantee in writing, and come back if it fails. Five values. No exceptions.

Heating Repair in Keene

Heating Repair in Keene covers furnaces, heat pumps, and the occasional wall heater still running in older university-area rentals. The job starts with a diagnostic to separate a failed ignitor from a control board, a bad gas valve from a safety switch that’s doing its job correctly. Most heating repairs in Keene fall between $150-$700, parts and labor included, and we hand you the written price before any wrench turns.

Johnson County winters don’t forgive a half-measure. After Winter Storm Uri in February 2021, we saw heat pumps and poorly insulated air handlers that were never designed for sustained sub-freezing temperatures. Emergency heat failed, control boards cracked from thermal shock, and homeowners learned the hard way that their equipment was sized for mild Texas winters that no longer guaranteed. We still get calls from Keene homeowners who want freeze-protection retrofits they didn’t need a decade ago.

Heat Exchanger Inspection and Repair

A cracked heat exchanger is the repair we refuse to patch and walk away from. Carbon monoxide risk is real, especially in Keene’s older homes where the original furnace may have been oversized for the ductwork and cycled on and off for forty years. If we find cracks, we show you with a camera, we shut the gas off, and we explain every option. No scare tactics, but no soft-pedaling either.

Ignitor and Flame Sensor Service

The hot surface ignitor in a modern furnace has no pilot light to relight. When it fails, the furnace tries to fire, gives up, and locks out. In Keene, we see this most often on systems that short-cycle because of duct pressure problems, the ignitor wearing out from excessive starts. We replace the part, but we also check why it failed.

Boiler Repair in Keene

Boiler Repair in Keene is less common than furnace work, but the older institutional buildings around Southwestern Adventist University and some of the original Adventist-community homes still run hydronic systems. The job involves circulating pumps, zone valves, expansion tanks, and the boiler itself. Most boiler repairs in Keene also fall in the $150-$700 range, though commercial-grade equipment on campus can run higher. We give you the written price before we start.

Boilers fail differently than forced-air furnaces. A leak in the loop drops pressure and triggers the safety. A failed circulating pump means the boiler runs but no heat reaches the rooms. Expansion tanks waterlog and cause pressure spikes that blow the relief valve. We carry parts for common residential boiler brands, and for the larger campus systems we coordinate with facilities staff to minimize disruption to occupied buildings.

Circulating Pump and Zone Valve Replacement

The pump is the heart of a hydronic system. When it seizes or the motor burns out, heat stops moving. Zone valves fail more often in buildings with many heating zones, like the older dormitories and classroom wings near the university. We test amperage draw, check for voltage at the valve actuator, and replace only what’s actually failed.

Pressure and Leak Diagnosis

A boiler that loses pressure has a leak somewhere in the loop, or a failed pressure-reducing valve letting water past. We pressure-test the visible piping first, then use listening equipment if the leak is in a slab or buried line. In Keene’s crawlspace and slab-on-grade construction, this can get interesting fast.

Trusted Brands We Service in Keene

Our technicians are trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common failure parts for Rheem and York systems locally, which means faster turnaround for Keene homeowners who can’t wait on a warehouse shipment. For Bryant and Daikin equipment, we maintain supplier relationships that let us source same-day or next-morning on most components. Whether your furnace is five years old or thirty, the technician who shows up can work on it.

Common Furnace Repair Problems We See in Keene Homes

• Cracked heat exchangers in aging mid-century furnaces. Keene’s original Adventist-community homes often have furnaces installed in the 1970s and 1980s that were never sized for the ductwork they serve. Decades of thermal cycling, especially after Winter Storm Uri’s sustained cold, fatigues metal until it fails. We inspect with a borescope and document everything.
• Undersized return plenums and deteriorated flex duct in crawlspaces. The original build-out used whatever duct size was cheapest, not what the furnace actually needs. High static pressure forces blower motors to pull excessive amperage, burning them out prematurely. Short-cycling follows. We measure static pressure with a manometer and show you the number.
• Electrical panels with no capacity for modern equipment. A 100-amp panel from 1965 cannot carry a variable-speed furnace, heat pump, and the rest of a modern household. We’ve seen nuisance trips that homeowners blamed on the furnace when the real problem was a panel that needed upgrading before any new equipment could run reliably.
• Control board failures after power events. Johnson County gets its share of brownouts and surge events. Older control boards lack the surge protection built into modern units, and a voltage spike can fry the board that runs the entire ignition sequence. We check for proper grounding as part of every repair.
