Commercial furnace repair services throughout Dallas-Fort Worth for office buildings, warehouses, retail centers, and industrial facilities. We repair gas furnaces in rooftop package units, standalone heating equipment, and industrial unit heaters, keeping commercial spaces warm during Texas cold snaps.
Most commercial buildings in the Metroplex use natural gas furnaces, either integrated into rooftop HVAC units or as standalone heating systems. These furnaces run trouble-free for years, but when something breaks during a January freeze or February ice storm, buildings lose heat fast. Ignition failures, cracked heat exchangers, gas valve problems, and blower motor issues show up at the worst possible times. Our technicians respond quickly with the diagnostic tools and parts inventory to complete most repairs on the first visit.
We service all major commercial furnace brands including Trane, Carrier, Lennox, York, Goodman, and Rheem. Our trucks stock common parts like ignitors, flame sensors, gas valves, blower motors, and control boards so we don’t waste time ordering components while your building stays cold. For larger industrial furnaces and make-up air units, we coordinate parts delivery and schedule repairs to minimize downtime.
Furnace problems don’t always announce themselves clearly. A building that’s heating unevenly might have a stuck zone damper or failing thermostat rather than a furnace issue. A rooftop unit that short-cycles could have a dirty flame sensor, bad pressure switch, or blocked flue. We diagnose the root cause rather than throwing parts at symptoms. As part of our comprehensive commercial heating repair services, we troubleshoot the entire heating system, furnace, controls, distribution, and ventilation, to find what’s really wrong.
A furnace failure at a North Dallas office building on a 20-degree morning affects everyone in the building. Employees can’t work comfortably. Tenants complain. Pipes risk freezing. You need heat restored now, not tomorrow. Our emergency repair service runs 24/7 because commercial furnace problems don’t wait for convenient business hours.
We dispatch technicians from across the Metroplex, Dallas, Plano, Fort Worth, Irving, Richardson, Frisco. That means faster response whether you’re managing a building along the Dallas North Tollway, an industrial facility near DFW Airport, or a retail center in Las Colinas. Our service vans carry combustion analyzers, multimeters, manometers for gas pressure testing, and an inventory of parts that fail most often on commercial furnaces.
Common furnace repairs include ignition system failures (hot surface ignitors and pilot assemblies), flame sensor cleaning or replacement, gas valve repairs, pressure switch problems, cracked heat exchangers, blower motor and capacitor replacement, limit switch failures, and control board issues. We also diagnose and repair furnace-related problems like blocked flue vents, condensate drain clogs, thermostat malfunctions, and sequencer failures on electric furnaces.
Our technicians perform combustion analysis during every furnace repair to verify an appropriate air-fuel mixture and ensure safe operation. A furnace that’s running but producing carbon monoxide or burning inefficiently creates safety risks and higher gas bills. We measure flue gases, verify draft, inspect flame appearance, and adjust combustion as needed.
Quick furnace repairs get your heat back on. Smart repairs extend the life of your equipment and prevent future breakdowns. When we service a commercial furnace, we look beyond the immediate problem. A failed ignitor might be the symptom, but heavy cycling from an oversized system or dirty filters could be the real cause.
Heat exchangers crack from thermal stress, corrosion, or poor combustion. A small crack can usually be detected during inspection before it becomes a safety issue requiring complete furnace replacement. We perform visual inspections, check for flame roll-out, and look for rust or corrosion patterns that signal developing problems. Catching these issues early saves thousands compared to emergency replacements.
Gas furnaces that burn efficiently cost less to operate. A furnace with a dirty burner assembly or improper gas pressure wastes fuel and produces less heat. During repairs, we clean burners, verify proper gas pressure and manifold settings, check orifices for blockages, and calibrate limit controls. These steps restore efficiency and reduce operating costs.
Blower motors and bearings wear over time. A motor drawing high amperage or making unusual noise will fail soon. We check motor condition during every service call and recommend bearing lubrication or motor replacement before complete failure leaves your building without heat. Belts get inspected for cracks and proper tension. Filters get checked because a clogged filter causes more furnace failures than any other single issue.
TTI, Inc. Testimonial
Furnace failures during cold weather create emergencies. The same problems caught during scheduled maintenance get fixed before they affect building comfort. Fall furnace inspections, before the first freeze, identify weak ignitors, dirty flame sensors, worn blower bearings, and gas valve issues while there’s still time to order parts and schedule repairs during normal business hours.
Our maintenance contracts include comprehensive furnace inspections twice a year. Technicians test ignition systems and flame sensors, inspect heat exchangers for cracks or corrosion, verify proper gas pressure and combustion efficiency, check and adjust burner flames, test limit switches and safety controls, lubricate blower motors and bearings, inspect and replace filters, verify proper venting and draft, clean burner assemblies, and calibrate thermostats and zone controls.
Buildings with planned maintenance experience fewer emergency calls. Equipment lasts longer because problems get caught early. Energy costs stay lower because furnaces run at peak efficiency. When something breaks unexpectedly, maintenance contract customers receive priority scheduling.
Most property management companies in Dallas, Plano, Richardson, Irving, Fort Worth, and Frisco offer maintenance contracts that cover their entire building portfolios. One contract, one point of contact, consistent service standards across all properties. Scheduled service visits occur before the heating season begins, not during a cold snap when every HVAC contractor in the Metroplex is already handling emergency calls.
Kahn Mechanical provides commercial furnace repair across the entire Dallas-Fort Worth Metroplex. We service buildings in Dallas County, Collin County, Tarrant County, and Denton County, from downtown high-rises to suburban office parks, from industrial warehouses near I-20 to retail centers along the President George Bush Turnpike.
Our technicians work daily along major commercial corridors including Highway 75 through Richardson and Plano, the I-635 loop around North Dallas, the Sam Rayburn Tollway through Collin County, and the I-30 corridor between Dallas and Fort Worth. We handle furnace repairs in the Telecom Corridor, Las Colinas Urban Center, Galleria Dallas area, Medical District, and throughout the corporate campuses in Frisco and North Dallas.
We service all commercial property types, office buildings, industrial facilities, warehouses and distribution centers, retail stores and shopping centers, restaurants, medical offices, schools and churches, municipal buildings, and multi-tenant properties. Each building type has different heating requirements. An office needs quiet, even heat. A warehouse needs economical heating that covers large square footage. A restaurant needs supplemental heat that doesn’t interfere with kitchen equipment.
Gas furnaces in rooftop units, standalone furnaces in mechanical rooms, industrial unit heaters in warehouses, infrared heaters in manufacturing facilities, make-up air units for commercial kitchens, we repair them all. Whether you manage one building or oversee facilities across multiple DFW locations, Kahn Mechanical delivers the same quality service and technical expertise on every call. Contact us at (214) 831-5551 when your commercial furnace needs repair, or schedule preventive maintenance before the next cold front arrives.
