    Commercial Furnace & Heating Repair

    Commercial furnace, rooftop-unit, and heating repair across Northern Colorado — fast 24/7 dispatch when the heat goes out and a Colorado cold snap is on the way.

    When commercial heat fails in a Colorado winter, the clock starts immediately — staff and customers are cold, and frozen pipes become a real risk within hours. Accutemp Services provides commercial furnace and heating repair across Northern Colorado for rooftop units (RTUs), gas furnaces, unit heaters, and make-up air systems. Our technicians handle the whole heating side — heat exchangers, ignition, gas valves, and combustion tuning — with 24/7/365 emergency dispatch and a 30-day labor warranty on every repair.

    Commercial heating failures in Northern Colorado aren't a comfort inconvenience — they're an operational emergency. A restaurant, retail store, warehouse, or office that loses heat when overnight temperatures drop below zero risks frozen and burst pipes, water damage, and a forced closure on top of cold customers and staff. That's why Accutemp runs true 24/7/365 dispatch through heating season: when your furnace or rooftop unit fails, a qualified technician is on the way fast, because in a Colorado cold snap the difference between a same-hour repair and a next-day one can be a flooded building.

    We repair the full range of commercial heating equipment. Packaged rooftop units (RTUs) with gas heat — the workhorses on top of most commercial buildings; gas-fired furnaces and air handlers; suspended and tube-style unit heaters that warm warehouses, shops, and garages; and make-up air units that replace the air kitchen exhaust hoods pull out. Across all of them, the failures we diagnose most are cracked or failing heat exchangers, ignition failures (hot-surface igniters, spark systems, and flame sensors), gas valve and gas-pressure problems, failed inducer and blower motors, rollout and limit-switch trips, and control-board faults. Cracked heat exchangers in particular are a safety issue — they can leak combustion gases — so we test for them and never return unsafe equipment to service.

    Combustion tuning is where our boiler-side expertise carries over to furnaces and RTUs. Using flue-gas analyzers, we measure combustion efficiency, CO, and draft to confirm equipment is burning cleanly and safely, not just running. Proper combustion setup protects efficiency (a poorly tuned gas furnace quietly wastes fuel all winter), extends equipment life, and — most importantly — verifies the equipment is safe. We service every major commercial brand: Trane, Carrier, Lennox, York, Rheem/Ruud, Daikin, and Reznor and Modine on the unit-heater side. For aging equipment, we give an honest repair-vs-replace assessment rather than a default upsell.

    The best heating repair is the one you never need. Because commercial heating equipment sits idle all summer and then gets slammed the first cold week of fall, failures cluster exactly when demand is highest and technicians are busiest. Our preventive-maintenance programs put heating equipment through a full pre-season startup — heat exchanger inspection, ignition and flame-sensor service, gas-pressure and combustion verification, blower and belt service, and safety-control testing — so the first cold snap doesn't take your building offline. PM clients get priority emergency dispatch when they do need it.

    Our Process

    1

    Emergency Dispatch

    A commercial heating failure in a Colorado winter risks frozen pipes within hours — our 24/7/365 line dispatches a technician fast across our Northern Colorado service area

    2

    Safe Diagnosis

    We diagnose the real failure — ignition, gas valve, heat exchanger, motor, or controls — and test for cracked heat exchangers and combustion-safety issues, never returning unsafe equipment to service

    3

    Expert Repair

    Our technicians repair with manufacturer-approved procedures and quality parts, most stocked on the truck so heat is restored on the first visit whenever possible

    4

    Combustion Verification

    Before we leave, we verify combustion, draft, and safe operation with a flue-gas analyzer so the equipment runs cleanly, efficiently, and safely

    Frequently Asked Questions

    Winter heating failures are our top-priority dispatch because a Colorado cold snap can freeze and burst pipes within hours. Our 24/7/365 line gets a technician moving fast — typically on-site within 30–60 minutes across our Northern Colorado service area — and you always reach a live person, night, weekend, or holiday, with no after-hours premium.

    We service packaged rooftop units (RTUs) with gas heat, gas furnaces and air handlers, suspended and tube-style unit heaters, and make-up air units. We handle heat exchangers, ignition systems, gas valves, inducer and blower motors, and controls across every major brand — Trane, Carrier, Lennox, York, Rheem/Ruud, Daikin, and Reznor/Modine unit heaters.

    Service calls start at $145 per hour with a 1.5-hour minimum (so the floor for any visit is $217.50). Parts are billed separately at standard markup and backed by the manufacturer's parts warranty. Major work like heat-exchanger replacement is quoted in advance. We provide a transparent estimate before any work begins, and the 30-day labor warranty covers every repair.

    The heat exchanger is the metal chamber that separates combustion gases from the air blown into your building. When it cracks — from age and thermal cycling — it can leak combustion byproducts, including carbon monoxide, into the airstream. It's a genuine safety issue, so we test for cracked heat exchangers during diagnosis and PM, and we never return equipment with a compromised heat exchanger to service. Depending on age and cost, the fix is either heat-exchanger replacement or unit replacement, and we lay out the honest tradeoff.

    Short-cycling and lockouts usually trace to a dirty flame sensor, a failing hot-surface igniter, a rollout or high-limit switch tripping from restricted airflow, a gas-pressure problem, or a control-board fault. A furnace that ignites then quickly shuts down is often flame-sensor or ignition related; one that never fires is often igniter, gas valve, or safety-switch related. We diagnose the actual cause rather than resetting it and hoping it holds.

    Yes — pre-season heating startup is the single best way to avoid a first-cold-snap breakdown. Commercial heating equipment sits idle all summer and then gets slammed the first cold week, so failures cluster exactly when everyone's furnace fails at once and technicians are slammed. A fall PM visit inspects the heat exchanger, services ignition and flame sensors, verifies gas pressure and combustion, and tests safety controls, so you're not the building calling for emergency heat in a snowstorm.

    Yes. Combustion tuning with a flue-gas analyzer confirms your furnace or RTU is burning cleanly and at proper efficiency — a poorly tuned gas system quietly wastes fuel all winter. We also check airflow, filters, and controls for additional efficiency opportunities. On older, inefficient equipment we lay out the repair-vs-replace math so you can decide with real numbers.

    Yes. We dispatch from Loveland and serve Fort Collins, Greeley, Longmont, Windsor, Berthoud, Johnstown, and the surrounding Front Range. Restaurants, retail, warehouses, offices, and institutional facilities across the region rely on us for both emergency furnace repair and pre-season heating maintenance.
