When your office or shop has no heat on a 28° morning, your team can't work and your customers don't show up. We service commercial heating across Mabank, Cedar Creek Lake Area, and the full DFW metroplex — rooftop heating sections, commercial gas furnaces, electric heat strips, unit heaters, tube heaters, and combination heating-cooling units. Every commercial heating call includes a full combustion analysis with a calibrated flue gas analyzer — documented in a written report for your insurance carrier, landlord, or OSHA-related requirements. Same prioritized commercial response as our AC service, with COI and W-9 available on request.
Commercial Heating Pricing — Honest Ranges
Commercial heating pricing varies by equipment size, complexity, and rooftop access. Typical Mabank / DFW ranges:
- Commercial heating diagnostic (with combustion analysis): $149-$219 (includes flue gas analyzer test and written CO report)
- Hot-surface igniter replacement (RTU): $340-$580
- Flame sensor cleaning / replacement: $220-$380
- Gas valve replacement (commercial): $680-$1,400 depending on BTU input and configuration
- Inducer motor replacement (RTU): $780-$1,400
- Commercial blower motor replacement: $580-$1,400 depending on HP and belt-drive vs direct-drive
- Control board / ignition control: $580-$1,200
- Heat exchanger replacement (commercial): $3,400-$8,200 — often replace-unit-instead decision on 12+ year old RTUs

- Emergency after-hours dispatch: +$50 diagnostic premium during freeze events
Commercial Heating Equipment We Service
- Rooftop unit heating sections — gas-fired and electric (Carrier, Trane, Lennox, York, Rheem, Daikin, AAON)
- Commercial gas furnaces — 80% AFUE through 95%+ AFUE condensing
- Electric heat strips and duct heaters — 5kW through 45kW capacity
- Heat pumps with backup heat — both electric strip and dual-fuel gas backup configurations
- Make-up air units with heating — restaurant kitchens, manufacturing, paint booths
- Tube heaters and radiant heaters — warehouses, garages, service bays, aircraft hangars
- Unit heaters — hanging warehouse/shop heaters, gas-fired and electric
- Boiler-fed hydronic systems — limited scope; we handle air-side maintenance, refer boiler work to specialized commercial boiler contractors
Combustion Safety — Why It Matters More in Commercial
Commercial gas heating creates significantly higher CO risk than residential:
- Larger BTU loads mean larger potential CO release from a single failure — commercial furnaces run 200,000-800,000 BTU vs residential 60,000-100,000
- Frequently older equipment — commercial equipment gets deferred maintenance more often than residential; 20-year-old commercial furnaces are common
- Complex venting — long horizontal runs, shared flues, forced-draft complications increase backdraft risk
- Higher occupancy — CO exposure affects more people simultaneously; liability risk is much higher
- Employees can't leave when they feel symptoms — workers stay through headaches thinking it's just the workday
Every commercial heating call we run gets a full combustion analysis with a calibrated flue gas analyzer. We measure CO in the flue gas, CO in supply air at multiple points, temperature rise, oxygen levels, and combustion efficiency. Written report handed to you at the end of the visit — useful for insurance, landlord/property management, and OSHA-related requirements.
Freeze-Event Emergency Response for Commercial
During freeze events, commercial no-heat calls get prioritized because revenue loss compounds by the hour:
- Restaurants: lost meal service AND health code risk (walk-in cooler doors freezing shut, dish sanitizer temp violations) — priority dispatch
- Medical / dental: patient safety and treatment continuity — priority dispatch
- Warehouses / distribution: product freeze damage risk (paint, chemicals, temperature-sensitive inventory) — priority dispatch
- Multi-tenant office buildings: tenant complaints multiply fast; property manager notification helpful for coordinated response
- Retail: customers don't shop cold stores; priority based on operating hours and current staffing
Membership contract customers get front-of-line commercial dispatch during freeze events. See commercial preventive maintenance contracts.
Same-Day Commercial Heating Repair — Mabank, Cedar Creek Lake & DFW
Searching "commercial heating repair near me"? We dispatch same-day for most commercial heating repair calls across our entire service area — Mabank, Gun Barrel City, Seven Points, Kemp, Tool, Athens, Kaufman, and the full Dallas–Fort Worth metroplex including Plano, Frisco, Allen, McKinney, Arlington, Mesquite, Garland, and Rockwall. A real human answers the line 24/7 — usually Eric, Brad, or a senior tech, never a call center. Whether you searched for "commercial heating repair", "commercial heating repair", "HVAC contractor near me", or "best HVAC company [your city] TX", we cover it — veteran-owned, locally operated, never acquired by private equity.
Brand-Name HVAC Equipment We Service
We service every major HVAC brand on the market across our Mabank and DFW service area: Trane, Carrier, Lennox, Goodman, Rheem, Amana, York, Bryant, American Standard, Heil, Daikin, Mitsubishi. Whether your existing equipment is 5 years old or 20, whether it's a high-end inverter system or a builder-grade base model, we approach the work the same way — honest diagnostic, flat-rate written quote, repair or install done right the first time.
Don't see your equipment brand listed? Call anyway. The HVAC industry only has a handful of core compressor and heat-exchanger manufacturers behind the dozens of consumer-facing labels — if it's a residential or light-commercial system, we likely service it.
Frequently Asked Questions
Can you respond same-day during a freeze for a commercial no-heat call?
Yes. Cold-weather no-heat calls in commercial spaces get priority dispatch — your business is losing revenue every hour you're closed, and pipe-freeze/health-code risks compound fast. We route the closest tech, not next-in-queue, during freeze events. Response times: 90-120 minutes in Mabank/Cedar Creek Lake, 2-4 hours across DFW depending on conditions.
Do you provide CO testing reports for commercial customers?
Yes — every commercial heating service includes documented combustion analysis with a calibrated flue gas analyzer. Written report covers CO in flue gas, CO in supply air, temperature rise, oxygen levels, and combustion efficiency. Useful for landlord requirements, insurance carriers, OSHA-related documentation, and Health Department inspections (especially restaurants).
How much does commercial heating repair cost?
Depends on equipment size and failure type. Commercial heating diagnostic (with combustion analysis) $149-$219. Common repairs: igniter $340-$580, flame sensor $220-$380, gas valve $680-$1,400, inducer motor $780-$1,400, control board $580-$1,200, blower motor $580-$1,400. Heat exchanger replacement $3,400-$8,200 (often replace-unit-instead on 12+ year old RTUs). All quoted flat-rate in writing before work begins.
What commercial heating brands do you service?
All major commercial brands: Carrier, Trane, Lennox, York/JCI, Rheem, Daikin, AAON, Bard for rooftop package units. Commercial gas furnaces from same brands plus Modine, Reznor for unit heaters and tube heaters. Make-up air units from Captive-Aire, Greenheck, Loren Cook, PennBarry. We stock common parts for RTUs in the 3-10 ton range.
Can you bill the property owner or landlord for commercial heating repairs?
Yes, with signed authorization from either the tenant or property owner. We're set up to invoice property management companies (Insite, JLL, CBRE, local managers) and provide W-9s, COIs, and any accounting documentation needed. Some landlords prefer we bill the tenant with a landlord-approved repair authorization cap — we handle that too.
Do you handle tube heaters and unit heaters in warehouses?
Yes — we service Modine, Reznor, Sterling, and other common warehouse unit heater brands. Ceiling-mounted tube heaters, hanging gas unit heaters, and infrared radiant heaters are all in scope. Warehouse heater work requires ladder access above 10 feet — we come equipped with proper access equipment and OSHA fall protection.
What if we suspect a CO leak in our commercial building?
Treat as a life-safety emergency. Evacuate all occupants immediately, call 911 if anyone shows symptoms (headache, dizziness, nausea, confusion), then call the gas utility (Atmos: 866-322-8667), then call us. Once emergency responders clear the building, we perform a full combustion analysis, inspect all gas-fired equipment, and provide written documentation of findings and repairs. See our CO alarm emergency guide.
