What drives replacement cost in Fort Worth
A straightforward condenser-only replacement, keeping the existing furnace or air handler and ductwork, typically runs $4,500 to $7,900 in the Fort Worth metro. A full split system replacement, including a new furnace and air handler alongside the condenser, runs $6,500 to $12,000 depending on tonnage, SEER2 rating, and brand.
Homes in older neighborhoods like Fairmount, Arlington Heights, and parts of Ridglea often need ductwork resizing or sealing alongside equipment replacement, since original ducts were sized for smaller, less efficient systems decades ago. Skipping that step to save money upfront often means the new high-efficiency equipment underperforms.
Heat pumps and the refrigerant transition
Heat pump installs or conversions typically run $7,000 to $14,000 in Fort Worth, with the higher end reflecting homes converting from gas furnace heat to an all-electric heat pump system, which usually requires electrical panel work in addition to the HVAC equipment itself. Given Fort Worth's relatively mild winters paired with a long, intense cooling season, a heat pump can make sense for many homeowners, though very cold snaps may still call for backup heat strips.
New residential AC and heat pump equipment sold in Texas is increasingly shifting from R-410A to R-454B under the federal refrigerant phasedown timeline, and contractors need updated tools and certification to install and service it safely. Ask any contractor proposing new equipment which refrigerant it uses and whether their installation crew is currently certified for it.
Permits and inspections for a replacement
Replacing a condenser, furnace, or air handler, or changing equipment type such as adding a heat pump, requires a mechanical permit inside Fort Worth city limits, filed through the city's Accela Citizen Access portal, with a final inspection required to close the permit 1. The Development Services Permits page also offers the Permit Assist tool to confirm exactly which permit applies to your project before you apply 2.
Get this in writing from your contractor: who is pulling the permit, the exact equipment model and refrigerant type, and the anticipated inspection timeline. Homes outside city limits near Benbrook, Aledo, or unincorporated Tarrant County may have a different permitting authority, so confirm jurisdiction before signing.
Choosing equipment and a contractor
Get two or three written estimates before committing to a full replacement, and make sure each one lists the same equipment specs, SEER2 rating, refrigerant type, and warranty terms so you are comparing apples to apples. Confirm the contractor's Texas ACR license and class through TDLR's license search tool before signing anything 3 4.

Common questions
How much does a full HVAC replacement cost in Fort Worth?
A full split system replacement, including a new furnace and air handler, typically runs $6,500 to $12,000 in the Fort Worth metro, while heat pump installs and conversions run $7,000 to $14,000.
Do I need a permit to replace my HVAC system in Fort Worth?
Yes. Replacing a condenser, furnace, or air handler, or changing equipment type inside Fort Worth city limits requires a mechanical permit filed through the city's Accela Citizen Access portal, plus a final inspection.
Is a heat pump a good fit for Fort Worth?
Heat pumps work well for many Fort Worth homes given the relatively mild winters and long cooling season, though very cold snaps can require backup electric heat strips. A licensed contractor should run a load calculation before recommending one for your home.
What is R-454B and why does it matter for a new system?
R-454B is the refrigerant replacing R-410A under the federal phasedown, and most new HVAC equipment sold in Fort Worth now uses it. Confirm your installer is certified to handle it before signing a contract.
How do I check a Fort Worth HVAC installer's license before a big job?
Search the contractor's license number on TDLR's verification tool at tdlr.texas.gov/verify.htm and confirm it is an active Air Conditioning and Refrigeration Contractor (ACR) license matching the company name.
