Central air installation with existing ductwork is priced after an in‑home evaluation because total cost depends on the equipment selected and any needed updates to make it run right. The biggest driver is proper sizing; a unit matched to the home avoids short cycling and unnecessary expense.
We install and support traditional and ductless systems, handle thermostat work, and can take care of ductwork and electrical ties as needed. Our team regularly completes AC installs across the Denver metro, including homes in Commerce City. Current promotions may reduce upfront cost, including $1,500 off an AC and furnace bundle.
What typically affects your final price:
- System capacity chosen for your home
- Efficiency level you prefer
- Condition of existing ductwork and needed cleaning/repair
- Thermostat upgrade or replacement
- Any electrical work to support the unit
Schedule an in‑home assessment to get a firm, all‑in price before you decide.
