HVAC Services in Greeley, CO
Greeley sits at about 4,700 feet on the eastern plains, with open wind, hot summers, and cold winters. From downtown Greeley to West Greeley, our HVAC team repairs, installs, and maintains the furnaces, boilers, heat pumps, and air conditioners Greeley homes depend on.
Greeley Heating and Cooling on the Eastern Plains
Greeley sits on the eastern plains, open to wind and weather from every direction. On the eastern plains, winter wind pushes cold air into Greeley houses, summer sun bakes the open lots, and storms sweep in with little to slow them down. That means heaters built for wind and cold, and coolers built for full sun and long, hot afternoons over open ground.
Housing in Greeley runs from late-1800s to early-1900s homes downtown to mid-century builds and new west-side subdivisions. Downtown homes often carry old ductwork, radiators, and boilers. New west-side homes run on high-efficiency furnaces, heat pumps, and AC units. White crust on faucets tells many Greeley homeowners the water is hard, and that same hard water wears on boilers and water-fed heating parts.
Greeley Repair, Installation, and Maintenance
Greeley sits at about 4,700 feet on the eastern plains, where open wind, hard water, and hot summers shape the work across the twelve services below, from downtown ductwork to West Greeley new builds.
Boiler Repair & Installation
Greeley hard water scales up boilers and clogs radiators, and we flush, repair leaks, and fix the pressure trouble it causes.

A heat pump suits Greeley shoulder seasons, and we install and repair units for Glenmere Park and Cranford homes with attention to wind and dust.
Learn more →AC Repair & Installation
Greeley AC units sit in full sun on open lots, and we repair warm air, frozen lines, and odd cycling for homes from Downtown to West Greeley.
Learn more →Ductless Mini-Split Services
A finished basement or a garage workshop in Kelly Farm gets heating and cooling from a mini-split, with no ductwork to run.
Learn more →Evaporative Cooler Services
Greeley swamp coolers run hard on dry plains air, and we keep pads, pumps, and water lines in shape.
Learn more →Indoor Air Quality
Plains dust blows into Greeley homes year-round, so filters, humidifiers, and ventilation keep indoor air cleaner and less dry.
Learn more →Maintenance & Tune-Ups
Greeley tune-ups get the furnace ready for plains storms and the AC ready for open-lot summers.
Learn more →Commercial HVAC
Downtown Greeley offices, shops, and campus-area businesses run rooftop units and split systems, and we keep them heating and cooling.
Learn more →Emergency HVAC Repair
When a Greeley furnace quits on a cold plains night, one call gets a technician on the way.
Learn more →Radiant & Hydronic Heating
Radiant heat under a Country Club West bathroom floor or a West Greeley addition warms evenly, and we repair cold loops and install new ones.
Learn more →ERV Installation
A Greeley home sealed against plains wind and dust traps stale air, and an ERV swaps it for fresh air while holding onto heat.

Plains wind finds leaks. Plains wind finds leaks in Greeley because the city sits open to wind from every direction. Cold air pushes into leaky ducts and wall gaps, and west-side homes on open lots catch the worst of it. We seal ductwork and check airflow so heat stays inside Greeley homes.
Hard water and boilers. In a downtown Greeley boiler, hard-water scale builds on the water-fed parts until you hear noise, feel slow heat, or spot a leak. We flush and service boilers and flag scale damage early, so downtown Greeley radiators keep heating evenly.
Old downtown ductwork. Late-1800s to early-1900s downtown homes often have ducts sized for a different era, so some rooms run hot while others stay cold. We test airflow, seal leaks, and rebalance supply.
Full sun on open lots. New west-side homes with young trees catch full sun, and AC units on the south side work overtime. A dirty coil or a low refrigerant charge shows up fast on a hot afternoon.
Dry air all year. Dry air is a year-round fact in Greeley, and winter heating dries it further. With plains dust blowing into homes year-round, the air feels dry and gritty at once. With plains dust blowing in year-round, a whole-home humidifier keeps Greeley indoor air comfortable and guards wood floors and furniture against the dry grit.
Open plains weather can turn fast over Downtown Greeley and the University District, so the National Weather Service forecast office in Boulder carries the Greeley forecast, and the EPA indoor air quality pages cover indoor air for homes that stay closed against plains wind and dust.

Greeley HVAC Questions, Answered
Yes. We serve Downtown Greeley, the University District, Glenmere Park, Cranford, Kelly Farm, Country Club West, St. Michael's, West Greeley, and Poudre River Ranch. Tell us your neighborhood when you call so we can plan the visit.
In Greeley, the rooms on the windward side run cold because plains wind drives cold air into leaky ducts and wall gaps. Downtown homes with ductwork from the late 1800s to early 1900s feel it worst. For those downtown homes, we seal ductwork, measure airflow, and hunt down insulation gaps until heat reaches every room and stays there.
Mineral scale is a common cause, and Greeley hard water is the reason. In late-1800s to early-1900s downtown homes, scale builds up in boilers and water-fed heating parts until it causes knocking, slow heating, and leaks. We flush and service boilers and flag scale damage before it spreads.
Yes, and they cool in summer too. Modern cold-climate heat pumps heat through Greeley winters, including cold nights on the open eastern plains. For Glenmere Park and Cranford homes we size the unit for the home, then check defrost cycles, airflow, and refrigerant charge so it holds output when the wind picks up.
Old ductwork is a common cause. Late-1800s to early-1900s homes often have ducts sized for a different era, with leaks and long runs that lose heat before it reaches the far rooms. We run an airflow check on those late-1800s ducts, seal what leaks, and rebalance the supply until the far rooms catch up.
Ahead of the first plains storm, change out the filter, clear vents and returns, and get the furnace or boiler checked. We inspect burners, ignition, safety controls, and airflow, and we flag worn parts before a cold night in West Greeley tests them.
