Frequently Asked Questions

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.
