Furnace Repair & Installation
A 1980s furnace in Arapahoe Highlands or Willow Creek usually fails as short cycling or cold air, and we repair ignition faults or replace units that keep breaking down.

Centennial Heating and Cooling for Aging Systems
Centennial is a southeast metro city built mostly in the 1970s to the 1990s, and its housing shows it. Two-story homes with mature trees fill Willow Creek, Cherry Knolls, and Southglenn. Systems in these homes are often original or on their second replacement, and ductwork from the original build decides how evenly they heat and cool.
Centennial sits higher than Denver, and its weather shows it. Winters in Centennial run colder than Denver's, storms drop snow fast over Willow Creek and Southglenn, and summer afternoons bring heat followed by thunderstorms. Heating systems need to handle cold snaps, and cooling systems need to handle hot afternoons and hail-season storms.
Centennial Services From Furnaces to ERVs
Centennial is mostly 1970s to 1990s subdivisions with original systems aging out under mature trees, so the twelve services below lean on replacement judgment, uneven-heat fixes, and tune-ups that keep old equipment honest.
Boiler Repair & Installation
When a Centennial radiator stays cold while the boiler runs, the fault is usually a stuck valve or trapped air, and we track it down.
Learn more →Heat Pump Installation & Repair
A heat pump suits Centennial shoulder seasons, and we install and repair units for Cherry Knolls and Heritage Greens homes with attention to defrost and airflow.
Learn more →AC Repair & Installation
Mature trees shade Centennial lots unevenly, so some rooms bake while others stay cool, and we trace warm air, frozen lines, and odd cycling to airflow, charge, or controls.
Learn more →Ductless Mini-Split Services
A finished basement or a garage conversion in Gleneagles gets heating and cooling from a mini-split, with no ductwork to run.
Learn more →Evaporative Cooler Services
A swamp cooler in Centennial cools on dry air, and we swap mineral-caked pads and fix pumps before the first hot week.
Learn more →Indoor Air Quality
Shade and tree cover keep some Centennial rooms damp while winter air dries the rest, so humidifiers, filters, and ventilation even things out.
Learn more →Maintenance & Tune-Ups
A yearly tune-up keeps a Centennial furnace and AC ready for hot summers and cold snaps.
Learn more →Commercial HVAC
Offices and shops near the Streets at Southglenn run rooftop units and split systems, and we keep them heating and cooling through every season.
Learn more →Emergency HVAC Repair
A Centennial furnace that quits on a cold night gets a technician on the way when you call us.
Learn more →Radiant & Hydronic Heating
Radiant heat under a Smoky Hill bathroom floor or a Knolls addition warms evenly, and we repair cold loops and install new ones.
Learn more →ERV Installation
A Centennial home sealed for winter traps stale air inside, and an ERV swaps it for fresh air while holding onto heat.
Learn more →Centennial Aging Systems and Shaded Lots
Original systems aging out. A 1970s to 1990s Centennial home often runs a furnace or AC that has served for decades, and failures show up as short cycling, cold air, or a unit that will not start. We repair those faults and replace systems that keep breaking down.
Mature trees, shaded lots, uneven heat. Big trees shade some rooms and leave others in full sun, so one side of the house runs warm while the other runs cold. We test airflow and balance supply so heat and cooling reach every room.
Higher altitude, thinner air. At 5,722 feet above the Denver metro, gas furnaces and boilers in Centennial burn in thinner air than at lower elevations. That means careful setup, venting, and combustion checks keep a Willow Creek or Southglenn system running safely and steadily.
Hot summers, hard-working AC. A long hot afternoon over Centennial's tree-lined subdivisions pushes a Willow Creek or Southglenn AC unit hard, and a low refrigerant charge or a dirty coil shows up as warm air or a frozen line. We find the cause and restore cooling from Willow Creek to Southglenn.
Dry air in winter. Winter heating dries indoor air in a Centennial home, and that shows up as static cling, cracked wood floors, and scratchy throats in the 1970s subdivisions. Whole-home humidifiers add moisture back and protect Centennial wood floors and furniture.
Cold snaps and hail-season storms hit Willow Creek and Southglenn fast, so read the Centennial forecast from the National Weather Service forecast office in Boulder, and for rooms that run damp under mature trees while winter air dries the rest, the EPA indoor air quality pages cover how to balance damp rooms and dry winter air indoors.
Centennial FAQs for Homeowners
Yes. We serve Arapahoe Highlands, Willow Creek, Southglenn, Cherry Knolls, Heritage Greens, Gleneagles, Smoky Hill, and The Knolls, along with the rest of Centennial. Tell us your neighborhood when you call so we can plan the visit.
We check how often your Centennial furnace has needed repair, how well it heats your Willow Creek or Cherry Knolls home, and whether parts are still available. If a Centennial furnace keeps breaking down or heats unevenly, a new furnace sized for your Willow Creek or Southglenn home usually serves you better than another repair.
Mature trees shade some rooms and leave others in full sun, and ductwork from the original build may favor one side. We test airflow and balance supply so heat and cooling reach every room.
Yes. A modern cold-climate heat pump heats a Centennial home through winters at 5,722 feet and cools it through thunderstorm-season summers too. We match the size to the house, whether a 1970s two-story in Willow Creek or a Cherry Knolls home under mature trees, and we check defrost cycles, airflow, and refrigerant charge so output holds on cold nights.
Yes, when the air stays dry. Centennial low humidity lets a swamp cooler cool a Willow Creek or Cherry Knolls home on most summer days, though mineral buildup on pads is the usual complaint. We replace pads crusted with mineral buildup and fix pumps and water lines, and when monsoon humidity arrives, a refrigerated AC takes over the cooling.
Change the filter, clear vents and returns, and have the furnace checked before the first cold snap hits Willow Creek and Southglenn. We inspect burners, ignition, safety controls, and airflow, and we flag worn parts before a cold night in Willow Creek or Southglenn tests them.
