AC Installation Cost in Carrollton, TX (2026)
For most Carrollton homeowners replacing a central air conditioner in 2026, the installed cost runs between $7,000 and $13,000 for an AC-only swap using existing ductwork, and $13,000 to $21,000 for a full system that includes a new furnace and air handler. Those ranges have widened slightly from prior years because of the industry-wide shift to R-454B refrigerant, which added roughly $500 to $1,000 to equipment costs across the board. Before you schedule estimates, it helps to understand what drives the spread and which local contractors are worth calling.

What You Can Expect to Pay in 2026
Price Ranges by Scope of Work
AC-only replacement — outdoor condenser, indoor evaporator coil, refrigerant, and labor on existing ductwork — typically lands between $7,000 and $13,000 installed in the Carrollton area. Sizing matters: a 2.5-ton unit runs roughly $4,800 to $7,500 fully installed, while a 3-ton system is closer to $5,200 to $8,500. If your home is larger or you are moving up an equipment tier for better efficiency, expect to be in the upper half of those ranges. A full system replacement covering the AC, furnace, and air handler together runs $13,000 to $21,000, depending on home square footage, equipment brand, and whether any electrical or ductwork upgrades are required. If your ductwork needs replacement, budget an additional $3,000 to $8,000 on top of the system cost. All figures are estimates; get multiple written quotes to find where your specific home lands.
Incentives and Tax Credit Update
What Is and Is Not Available in 2026
The federal Section 25C energy efficiency tax credit, which had allowed homeowners to claim up to $600 on qualifying HVAC equipment, expired on December 31, 2025, and is not available for systems purchased in 2026 as of this writing. That is a meaningful change from recent years, so do not factor it into your budget unless you have confirmed a legislative update. One rebate that is still active: Oncor’s Home Energy Efficiency program offers $400 to $600 back on qualifying high-efficiency equipment, with the program open January through November. Ask your contractor whether the system they are quoting qualifies, and request documentation you can submit directly to Oncor. Carrollton falls within Oncor’s service territory, so most homeowners here are eligible to apply.
Best for Upfront Pricing and Long-Term Warranty Protection
Varsity Zone HVAC
The single issue that generates the most frustration among Carrollton homeowners after an AC installation is discovering what a warranty actually covers when something breaks three or four years later. Most contractors in this market back their labor for one to two years. After that window closes, the equipment manufacturer may replace a failed part under a 10-year parts warranty, but the homeowner still pays full labor rates to have a technician install it — often $300 to $600 or more for a compressor swap. That gap between a covered part and an uncovered repair bill is where a lot of warranty surprises live.
Varsity Zone HVAC covers both parts and labor for 10 years, which eliminates that exposure entirely. They also offer free upfront quotes without requiring a two-hour in-home sales presentation before giving you a number — a process that remains common in this market and that most homeowners would rather skip. Varsity Zone is a Trane Comfort Specialist, offers financing, and uses online scheduling. They are based in Frisco and serve Carrollton, Plano, The Colony, Little Elm, Prosper, Celina, and Aubrey. Reach them at (972) 402-6948.
Best for Fast Local Response and Full-Service Coverage
LEX Air Conditioning and Heating
LEX has been serving Carrollton and the surrounding DFW area since its founding in 2004, with roots going back to 1990. They are a Trane Comfort Specialist and employ NATE-certified technicians, which is a meaningful credential — NATE certification requires passing standardized exams on HVAC installation and service. Their advertised 20 to 30 minute response times for service calls make them a reasonable choice when a system fails mid-summer and you cannot wait. They are also BBB Accredited and handle plumbing and electrical in addition to HVAC, which can simplify coordination if your installation requires panel or gas line work.
Best for Established Local History
Quigley Heating & Air
Quigley has been working in the Carrollton market since 1945, which means they have been installing and servicing systems through every major equipment transition the industry has seen. For homeowners who weight contractor longevity heavily, that track record is difficult to match. They are licensed, bonded, and insured, and their service menu covers ductless mini-splits, heat pumps, duct cleaning, and whole-home humidity control in addition to standard central AC. North Texas humidity in July and August is not subtle, and whole-home humidity management is an underrated component of comfort in older Carrollton neighborhoods.
A Note on Permitting in Carrollton
Carrollton requires a mechanical permit for AC system replacements, and the contractor you hire is responsible for pulling it. Before signing any contract, confirm that the permit is included in the quoted price and that the contractor will schedule the required city inspection. Hiring an unlicensed contractor to avoid permit costs is a short-term savings that can create real problems at resale. Under Texas law, HVAC contractors must hold a license issued by the Texas Department of Licensing and Regulation (TDLR), carry insurance, and have at least four years of relevant experience within the past six years. Verify any contractor’s TDLR license number before work begins.
Frequently Asked Questions
How much does a new AC system cost in Carrollton, TX in 2026?
For an AC-only replacement using existing ductwork, most Carrollton homeowners should budget $7,000 to $13,000 installed. A full system replacement including the furnace and air handler typically runs $13,000 to $21,000. These are estimates; your final cost depends on home size, equipment tier, and whether ductwork or electrical upgrades are needed.
Is the federal HVAC tax credit available in 2026?
No. The Section 25C tax credit expired at the end of 2025 and is not currently available for 2026 purchases. Carrollton homeowners can still apply for Oncor’s rebate program, which offers $400 to $600 on qualifying high-efficiency equipment through November.
What questions should I ask before hiring an HVAC contractor in Carrollton?
Ask for the contractor’s TDLR license number and verify it online, confirm the permit is included in the quoted price, and ask specifically how many years of labor the warranty covers — not just parts. A parts-only warranty after year two can still result in significant out-of-pocket costs when a repair is needed.
Does Varsity Zone HVAC serve The Colony?
Yes. Varsity Zone serves The Colony along with Carrollton, Plano, Frisco, Little Elm, Prosper, Celina, and Aubrey. Homeowners in The Colony can reach them at (972) 402-6948 or schedule online.
Why does the R-454B refrigerant transition matter for my 2026 installation?
The industry-wide shift from R-410A to R-454B refrigerant, which took effect for new equipment in 2025, increased unit manufacturing costs. That increase has been passed through to consumers, adding roughly $500 to $1,000 to typical installed prices compared to a system purchased before the transition. Any new central AC system installed in 2026 will use the newer refrigerant, so this cost is already baked into current quotes.
