Cost of furnace and ac installation — Round Rock, TX

Last updated: September 24, 2026

What affects the price

When you are looking at the price of a new HVAC system, several variables come into play. The total depends heavily on the square footage of your home, the existing ductwork condition, and the efficiency rating of the unit you choose. Opting for advanced features like smart thermostats or high-performance air filtration will also shift the final number. If we need to modify your home’s electrical setup or gas lines to accommodate the new equipment, that adds to the labor requirements.

About this service

Replacing both units at once is often more cost-effective because the technician can integrate the systems for peak efficiency. The price depends on the fuel type of the furnace and the capacity of the AC unit. Since you are installing two major components, labor costs are consolidated. We provide exact pricing confirmed free on the call.
