What Is the Average HVAC Installation Cost for a New System?

The average HVAC installation cost for a new system varies and is confirmed only after an in-home assessment. Most price differences come from matching equipment to your home’s needs, the scope of work, and the efficiency level you choose. Our local team serves the Denver metro and often works in Thornton homes.

Key factors that push costs up or down:

• System type: central AC, heat pump, furnace, or ductless mini-split.
• Capacity and efficiency needed for your home’s size and comfort goals.
• Ductwork condition or new duct runs.
• Installation complexity: equipment location, thermostat upgrades, and old equipment removal.
