Trusted HVAC Service in Firestone

Firestone is one of the fastest-growing towns in the Carbon Valley. It had about 1,900 residents in 2000, more than 10,000 by 2010 and over 16,000 by 2020, with housing units climbing from about 3,500 to more than 5,600 in the 2010s alone. That means most homes in town were built by production builders in the last 25 years, and their heating and cooling systems are arriving at predictable milestones together.

Homes from the 2000s building boom now have furnaces and air conditioners around 20 years old, and established neighborhoods such as Saddleback, St. Vrain Ranch, Oak Meadows and Mountain Shadows are where we expect to see that wear first. Some AC systems installed before 2010 still use R-22 refrigerant, which is no longer produced, so a major leak on one of those units is a replace-or-repair decision. Newer neighborhoods such as Barefoot Lakes, which opened in 2016, have high-efficiency condensing furnaces whose most common problems involve condensate drains and PVC venting rather than worn parts.

Builder information for Barefoot Lakes lists Black Hills Energy for natural gas and United Power for electricity, so check those utilities for rebates if you're replacing equipment. The Town of Firestone Building Division issues permits, including a single residential permit category that covers replacing an AC, a furnace or both. We test combustion and carbon monoxide on every furnace call.
