NATE - Certified

Heating & Air Conditioning in Fort Lupton, CO — Permitted by the City, Not Weld County

McCormick Heating & Cooling sends NATE- and EPA-certified technicians into Fort Lupton homes every week. Work covers the older blocks of Lupton Village and Fulton Village to the newer filings at Vista Meadows, Lancaster Crossing, and Sweetgrass Meadows. 

At 4,914 feet, Fort Lupton's heating season runs to roughly 6,113 heating degree days a year (NOAA weather station, Brighton 3 SE, 9.8 miles south). That is a serious workload for any furnace, and it lands hardest on this city's housing stock, which is the oldest anywhere we serve.

What HVAC Services Does McCormick Provide in Fort Lupton?

McCormick provides residential heating services throughout Fort Lupton, including furnace repair, furnace installation and replacement, and furnace tune-up and maintenance, plus emergency furnace repair when a January failure can't wait for business hours.

On the cooling side, we repair, replace, and maintain central air conditioning systems across the city, where summer highs push past 90°F. Homes draw their power from United Power, the member-owned electric cooperative headquartered in nearby Brighton rather than an investor-owned utility.

Why Do Fort Lupton's Older Homes Need Different Heating Work?

Fort Lupton's median home was built in 1980. Nearly half of the city's homes (49.8%) predate 1980, a full 12.5% were built in 1939 or earlier, and only 9.5% date from 2010 or later. In practical terms, that changes what a furnace visit looks like.

Furnaces in homes this age have worked through decades of long, hard winters, and that wear shows up in ways newer neighborhoods just haven't seen yet. The most serious is a cracked heat exchanger, the part that keeps combustion fumes separated from the air blowing into your home. It's one of the main reasons an older furnace gets replaced rather than repaired.

Older homes also have a hidden venting issue that newer ones don't. Many were built with a single chimney flue shared by the furnace and the water heater. When the furnace gets upgraded to a modern high-efficiency model, it vents out the side of the house instead, and the water heater is left using a chimney that's now too big for it alone. The exhaust rises too slowly, moisture builds up inside the chimney, and fumes can even drift back into the house instead of going up and out.

In Lupton Village and Fulton Village, the older core of the city, we check for exactly this on every furnace replacement. It's a conversation a Fort Lupton homeowner needs to have that the owner of a 2015-built house simply doesn't.

Who Permits a Furnace Replacement in Fort Lupton?

The City of Fort Lupton Building Department. Not Weld County. Weld County only issues building permits for unincorporated areas. Inside city limits, jurisdiction belongs to the City, which issues its own over-the-counter furnace replacement/repair permit. It's an easy detail to miss for a contractor who doesn't regularly work in Fort Lupton, and the consequences fall on the homeowner. Assuming county jurisdiction either delays your project while the paperwork gets rerouted, or worse, the permit gets skipped entirely. An unpermitted furnace replacement is a problem that surfaces at inspection, at an insurance claim, or at resale, long after the contractor is gone.

Fort Lupton enforces the full 2024 I-code family, including the International Mechanical Code and International Fuel Gas Code. When McCormick replaces a furnace in Fort Lupton, the permit goes through the City Building Department and the installation is built to the code edition the City's own inspectors will check it against.

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!
