Air Conditioning
Delivering reliable comfort from the scorching Front Range summers to the frigid High Country winters. Our expertise spans the full spectrum of cooling solutions: residential and light-commercial split systems, energy-efficient ductless mini-splits perfect for older homes and remodels without existing ductwork, rooftop package units, variable-refrigerant-flow (VRF) systems, large-scale water-cooled and air-cooled chillers for commercial buildings, cooling towers, and comprehensive preventative maintenance programs that keep systems running efficiently at 9,000 feet just as well as they do in Denver.
Moving forward
The HVAC industry is undergoing a major refrigerant phase-out driven by global environmental regulations to reduce climate impact. R-22 (Freon), a hydrochlorofluorocarbon (HCFC) with high ozone-depleting potential, was completely phased out of production and import in the United States by January 1, 2020—making repairs on older R-22 systems increasingly expensive as reclaimed refrigerant becomes scarce. Its replacement, R-410A (Puron), has zero ozone depletion but a high global warming potential (GWP of 2,088), is now being phased down under the EPA’s AIM Act and new 2025 efficiency standards. Starting January 1, 2025, new residential and light-commercial air conditioners and heat pumps can no longer use R-410A and must transition to lower-GWP A2L refrigerants such as R-32 (GWP 675) or R-454B (GWP 466). These modern refrigerants cut climate impact by 70–78% while maintaining or improving system efficiency, though they are mildly flammable and require updated safety standards, sensors, and technician training. The shift is already here—protecting both the planet and your future comfort.
Common issues
About 80% of the “no cooling” service calls we run in Colorado boil down to three simple, preventable issues: a clogged air filter choking off airflow, dirt-caked evaporator coils in the furnace or air handler turning your system into an ice block, or grimy outdoor condenser coils that can’t reject heat in 95-degree weather. The fourth most common culprit? A failed run capacitor—usually a $20–$40 part that leaves the compressor or fan motor dead in its tracks. These aren’t mysterious breakdowns; they’re almost always the result of skipped maintenance in our dusty, dry climate. A quick filter change, annual coil cleaning, and capacitor check can save you hundreds in service fees and keep your system from an early grave. Regular tune-ups aren’t optional here—they’re the difference between a cool house and an expensive surprises.
