Heating & Air Conditioning in Loveland, CO

At 5,000 feet, Loveland is the highest-elevation city McCormick Heating & Cooling serves, and it carries the heaviest heating load anywhere we work: 6,608 heating degree days a year, roughly 22% more heating demand than Greeley just down US-34. That combination changes how a furnace should be selected here, because equipment that performs fine at lower elevations east of I-25 runs short in a Loveland January. When your system can't keep up, call (720) 217-4801.

What HVAC Services Does McCormick Provide in Loveland?

McCormick provides residential heating services and cooling service across Loveland, from Mariana Butte on the west side to Centerra / Millennium East out by I-25. If your system has stopped keeping up, furnace repair in Loveland covers what a diagnostic visit involves here. When a unit has reached the end of its life, furnace installation in Loveland explains how we size a replacement for this specific climate. We also handle furnace tune-up and maintenance, furnace repair and furnace installation and replacement across the region, and emergency furnace repair when a mid-winter failure won't wait for business hours.

Why Do Loveland Homes Need More Heating Than Most of Northern Colorado?

Loveland's annual heating load is 6,608 heating degree days (NOAA 1991–2020, station Loveland 2 N), the highest of any city in McCormick's service area, and about 22% above Greeley's 5,431. On top of that, every gas furnace loses rated output with altitude, and at 5,000 feet Loveland takes the biggest derate of anywhere we work. This means a furnace sized for Greeley will be undersized in Loveland. The nameplate BTU number on the box is not what the equipment delivers at this elevation, against this winter.

Loveland's housing stock complicates it further. The median home here was built in 1993, but that average hides a split: 34.1% of housing predates 1980, concentrated in the older core, while 38.5% is post-2000 construction in neighborhoods like Mariana Butte, Seven Lakes North, Kendall Brook, and Alford Lake. 

Those are two different equipment generations. The pre-1980 homes are often on their second or third system with duct work designed for a different furnace class, while post-2000 homes in Centerra are starting to hit first-replacement age now. A load calculation that accounts for the home's actual era and Loveland's actual climate is the difference between a system that keeps up and one that runs constantly and still falls behind.

Who Permits a Furnace Replacement in Loveland?

The City of Loveland Building Division issues the permit, through its HVAC Fast Track application. If the replacement furnace vents in PVC, as most high-efficiency condensing furnaces do, Loveland additionally requires an Exhaust Test Certification. This step regularly catches crews used to working across county lines. The city has been on the 2024 ICC family of codes since July 1, 2026, with local design criteria that include a 30-inch frost depth.

Utilities in Loveland are split between two providers: electricity comes from Loveland Water and Power, the city's own municipal utility and a Platte River Power Authority owner-city, while natural gas is served by Xcel Energy. A contractor working in Loveland needs to know they're not the same utilities a Greeley homeowner deals with.

McCormick’s came through again with Justin doing a great job for us. We had furnace and A/C maintenance done at our new house to make sure everything was working properly. A couple of issues were found and Justin had them fixed within a couple of hours. Now we have peace of mind about our HVAC system. Highly recommend McCormick’s!

CALL (720) 217-4801. Technicians are dispatched from McCormick's Greeley headquarters at 2881 S 31st Ave, west on US-34 into Loveland. Tell us your neighborhood and what the system is doing.
