Furnaces
We install Trane modulating and variable-speed furnaces because they keep temperatures steady, stay quiet, and integrate cleanly with the ductwork we care about. The right furnace heats efficiently and keeps rooms comfortable when the temperature swings.
What it is
A Trane furnace paired with proper ductwork delivers even heat and quiet operation. We focus on modulating or two-stage variable-speed furnaces because they match the load, keep fans slow, and avoid the blasts that oversized units create.
Who it is for
- Homes looking to replace an aging single-stage furnace with a quieter, more efficient option
- Projects that want clean duct transitions and proper air balancing
- Owners planning for future heat pump or dual-fuel integration

Furnace FAQ
Why Trane furnaces?
We lead with Trane modulating and variable-speed furnaces because they stay quiet, match load in real time, and come with strong parts support. They are a natural fit for Boulder County homes.
How long does an install take?
Most furnace swaps take one day. If we are replacing flues, moving duct trunks, or running new gas/electrical we will map that out in advance, but typical installs finish within a single day.
What is the price range?
Gas furnace installs in Boulder County start around $8,500. Combined AC and furnace or cold-climate heat pump and furnace systems start higher because they include both heating and cooling equipment.
Do you offer maintenance or repairs?
Yes. We tune, commission, and service all the furnaces we install, and we can diagnose most other systems as well. Annual maintenance keeps warranties healthy and airflow dialed in.
Are HVAC repairs guaranteed?
