We’ve been driving to Centennial since the Willow Creek and Foxridge subdivisions were new construction. Glen Hartman started this company in 1984, and our technicians know the 80112 corridor’s heating systems the way a farmer knows his fields. We understand the altitude derating that sea-level contractors miss, the undersized return-air chases in 1980s ranches, and the Chinook wind cycles that punish ignitors and gas valves. When your furnace quits at 2 a.m., a live person answers our phone, and we’ll be there when we say.

Our Heating & Furnace Services in Centennial
Furnace Repair
Centennial’s daily temperature swings of 40-50°F force furnaces to cycle aggressively, wearing out ignitors, gas valves, and blower motors faster than in milder climates. A typical furnace repair in Centennial runs $150-$700. We carry replacement ignitors, gas valves, and control boards for Carrier, Trane, Bryant, and American Standard systems on every truck. Most repairs are done in one visit.
Furnace Replacement
Here’s what separates Centennial from every nearby city: at 5,900 feet elevation, every new furnace must be derated approximately 4% per 1,000 feet above sea level with a high-altitude orifice kit or altitude adjustment. Install a sea-level-rated unit without this spec, and it runs rich, overheats, and fails prematurely. Neighboring cities at lower elevations don’t face this requirement with the same severity. We’ve replaced hundreds of altitude-kitted systems in the 80112 corridor, and we warranty our work with the 90-Day Done Right Promise in writing.
In a 1986 ranch off South Franklin Street in Foxridge, we found an original forced-air furnace with a cracked heat exchanger and a 3-ton A/C condenser fighting a single undersized return - the return was only sized for heating. We replaced the furnace (Rheem, altitude-kitted) and upsized the return air chase; the short-cycling compressor issue vanished. That’s the difference between a parts-swapper and a technician who reads the whole system.
Furnace Tune-Up
Our $89 Seasonal Tune-Up is built for Centennial’s punishment. We check heat exchanger integrity, combustion analysis at altitude, gas pressure with proper derating, and ignitor wear patterns. The semi-arid climate and moderately hard municipal water also mean we inspect humidifier pads and solenoids, which clog and fail faster here. A tune-up in Centennial isn’t a checklist from sea level. It’s a diagnostic for a furnace that cycles 300+ days a year.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are the most serious failure we find in Centennial’s 30-50 year old housing stock. The combination of altitude-ignored derating on older replacements and aggressive cycling from Chinook temperature swings creates thermal stress that cracks steel. We perform combustion analysis and visual inspection on every service call, and we will show you what we find. A cracked heat exchanger means replacement - no exceptions, no patch jobs. We explain why, we show you the crack, and we quote replacement with no pressure.

Trusted Brands We Service in Centennial
We train our technicians as journeymen on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Heating & Furnace in Centennial customers, we stock the most common failure parts locally - ignitors, gas valves, control boards, blower motors, and altitude-specific orifice kits. That means faster turnaround and fewer return trips. We don’t order parts from a warehouse three states away and make you wait.
Common Heating & Furnace Problems We See in Centennial Homes
- Altitude derating ignored on replacement furnaces. Older furnaces or replacements installed without high-altitude orifice kits run rich, overheat, and crack heat exchangers. We’ve found units in Willow Creek installed by out-of-market contractors with no derating at all.
- Undersized return-air chases from heating-only original ductwork. When central A/C was retrofitted onto 1980s ranches, the return was never upsized. A single return fighting a 3-ton condenser causes refrigerant short-cycling that looks like compressor failure but is really duct design. No amount of parts-swapping fixes it.
- Aggressive cycling from 40-50°F daily temperature swings and Chinook wind events. These push midwinter temps from 10°F to 65°F in hours, forcing furnaces to start, stop, start again. Ignitors and gas valves wear out prematurely. We see this pattern constantly in Foxridge and Southglenn-area homes.
- Whole-home humidifier failures from moderately hard municipal water. The semi-arid climate demands humidification, but scale buildup clogs solenoids and pads faster than homeowners expect. We check this on every tune-up.

FAQs - Heating & Furnace in Centennial
Overheating in Centennial’s older furnaces usually traces to one of three causes: altitude derating ignored on a past replacement, a cracked heat exchanger restricting airflow, or a blower motor weakened by decades of cycling against undersized returns. The 5,900-foot elevation means combustion air is thinner; without proper orifice sizing, the furnace runs too hot. Call (866) 561-3358 and we’ll diagnose it with combustion analysis - estimates are free.
At 40 years, replacement is almost always the smarter money. Original furnaces in Foxridge and Willow Creek are past design life, parts are obsolete, and efficiency ratings of 60-70% mean you’re burning dollars. A new 80-96% AFUE furnace with proper altitude derating pays back through lower gas bills and ends the repair cycle. We give straight talk about repair versus replace, never pressure. Call for a free replacement quote.
In Centennial’s 1980s ranches, an undersized return-air chase is the likely culprit. Original ductwork was engineered for heating only; when A/C was added later, the single return cannot move enough volume. The compressor short-cycles on refrigerant pressure, not electrical failure. We’ve fixed this exact issue dozens of times in the 80112 corridor by upsizing the return. No parts-swapping required - just proper duct design. Call (866) 561-3358 for diagnosis.
Yes. Rheem is one of the nine brands we train on, and we stock common Rheem ignitors, gas valves, and control boards. We also install Rheem replacements with proper high-altitude orifice kits for Centennial’s 5,900-foot elevation. Call for same-day service or a free replacement estimate.
The 40-50°F daily swings and Chinook wind events force your system to cycle far more than in stable climates. That means more ignitor and gas valve wear, more thermal expansion stress on heat exchangers, and more opportunities for combustion drift. We recommend annual tune-ups with combustion analysis, not just a filter change. Our $89 Seasonal Tune-Up is built for this exact punishment. Call to schedule.
