Greeley & Weld County, Colorado

Heating and cooling, set up for 4,600 feet.

Copperfield installs, repairs and maintains furnaces, air conditioners and heat pumps for homes, and rooftop units and shop heat for businesses — adjusted for the thinner air of the high plains.

Why altitude matters

Equipment is rated at sea level. Greeley isn't.

At about 4,660 feet, every cubic foot of air carries roughly 15% less oxygen than at sea level. Gas burners, fans and coils all notice. Setting equipment up for the real conditions is part of every install and tune-up we do.

What we do

Three kinds of visit.

Repair

No heat, no cooling, strange noises, a system that runs but never catches up. Diagnosed and explained before anything is replaced.

Maintenance

Fall furnace and spring cooling tune-ups for homes; scheduled service for business equipment. Combustion checked, not guessed.

Replacement

Sized for your house or building at this altitude, installed to the manufacturer's high-altitude instructions, and explained line by line.

Questions

Good questions, plain answers.

Does altitude affect my furnace?

Yes. Greeley sits at about 4,660 feet, where the air holds roughly 15 percent less oxygen per cubic foot than at sea level. Gas burners have to be set up to the manufacturer's high-altitude instructions so they burn cleanly, and a furnace's effective output is lower than its sea-level rating.

Why is my house so dry in winter?

Cold outdoor air holds very little moisture, and Colorado air is dry to begin with. Once it is heated indoors, relative humidity can drop very low. A humidifier on the furnace, set correctly for the outdoor temperature, can help without causing condensation on windows.

Do you work on homes or businesses?

Both, equally. Furnaces, air conditioners and heat pumps for houses, and rooftop units, split systems and shop heating for offices, restaurants, shops and agricultural businesses across Greeley and Weld County.

Should I get a carbon monoxide alarm?

Yes. Colorado law requires carbon monoxide alarms near sleeping areas in homes with fuel-fired appliances or attached garages when a home is sold, remodeled or newly built, and they are worth having regardless.

Does Copperfield do coatings or painting?

No. “Coatings” is part of the name, not the trade. Copperfield is a heating, ventilation and air conditioning contractor only.
