How much does it cost to install a new AC and furnace?
Installing a new AC and furnace is priced after an in-home evaluation because equipment size, efficiency, and site conditions vary by home. The biggest driver is selecting a properly matched system that meets your comfort needs without oversizing. We assess your current setup, discuss goals, and provide a clear, line-item proposal. Our teams frequently handle replacements across the Boulder–Denver area, which helps us anticipate common layout challenges.
Key factors that change total price include:
- Ductwork repairs or modifications and airflow balancing
- Location and access for the indoor/outdoor units and line-set length
- Electrical or gas upgrades, condensate drainage, and venting needs
- Add-ons such as smart thermostats or indoor air quality equipment
We offer a free install estimate, with financing available subject to approved credit. To avoid surprises, book an on-site visit so a licensed tech can size the system and confirm any needed upgrades.
