New central AC, swamp cooler conversions and high-efficiency upgrades for Boulder homes, with a written proposal first.
A new AC in Boulder has to handle bright high-altitude sun and hot, dry afternoons. Historic homes near downtown, mid-century homes in south Boulder, and a significant number of rental properties. Boulder has some of the most ambitious local climate and electrification goals in Colorado, which shapes how many owners think about their next system. Every project starts with a free estimate that looks at your ducts, returns and the rooms that never cool, then we recommend equipment that fits.
Many Boulder homes were built with little or no AC, so cooling projects are often first-time installs where a heat pump can do double duty.
The right AC starts with the right numbers. We measure the home, check return air, and choose between single-stage, two-stage and variable-speed equipment based on comfort and noise goals. Installation includes matched components, proper evacuation, measured refrigerant charge, permits where required and a walk-through.
Denver-area cooling loads are mostly dry heat rather than humidity, and at about 5,400 feet the sun is intense. That changes equipment settings and airflow targets, and we set them for Boulder conditions rather than generic defaults.
| Service | Typical range |
|---|---|
| Central AC on an existing furnace and ductwork, 2 to 3 ton | $6,000 to $9,000 |
| High-efficiency two-stage or variable-speed AC | $9,000 to $14,000 |
| Swamp cooler to central AC conversion | $7,500 to $14,000+ |
| First-time AC requiring new ductwork | $12,000 to $20,000+ |
Typical range, exact quote after free estimate. Consider a heat pump too: qualifying systems may be eligible for Xcel Energy and Colorado incentives.
