AC-only or a complete system? Compare the same work.
These are Varsity Zone of Frisco’s installed estimates for one single-stage system. Keeping a compatible furnace is a different project from replacing heating and cooling together.

Cooling that adjusts
Illustrated roomOn a warm afternoon
A little more in tune.
An inverter changes its cooling output as demand changes. Longer operation at reduced output can help your home feel more even.

What does AC replacement cost in DFW?
Our current gas furnace + AC estimates range from $8,704.50 to $14,717.4 installed for one system, depending on size and efficiency tier. Choose your project and the number of systems you want to replace to see the relevant options. A home assessment confirms equipment sizing, installation requirements, and your final quote.
What is included in the estimate?
A complete matched gas furnace and AC system, installation, removal of your old equipment, permit and inspection, a smart thermostat, and the published 10-year parts and labor warranty. The assessment confirms the exact installation scope and applicable warranty terms.
Do I have to give you my phone number to see prices?
No. All three estimates are visible here without your name, email, or phone number. If you choose to request a home assessment, we will ask for the contact details needed to follow up.
Can I finance a new system?
Ask Varsity Zone of Frisco about current payment options. Financing is subject to credit approval and lender terms; your written quote confirms available options.
How do you know what size system I need?
You do not need to know your system size to see prices. We show ranges across our published sizes until equipment fit is confirmed at your home. Insulation, windows, layout and other conditions affect the right size; we do not size equipment from square footage alone.
