What does HVAC replacement cost in Texas?
Texas is not one HVAC market. El Paso, Amarillo, Dallas and Houston have different loads, different humidity and, since February 2021, a shared reason to take the heating side seriously. Rather than publish an average that fits none of them, this page shows exactly what moves a Texas quote, then gets TDLR-licensed local contractors to price your actual house. Free, no obligation.
14.3 SEER2
minimum for a split-system AC under 45,000 Btu/h installed in Texas, which sits in DOE's Southeast region

from this date municipalities cannot charge registration fees to TDLR-licensed AC contractors, though building permit fees still apply
The process
- Tell us what you are replacing, how the house is heated and what the ducts are doing. Two minutes, no account.
- We pass your details to HVAC contractors covering your ZIP code, and to no one else.
- They quote your actual job. Compare on one scope, check the TDLR license, choose or walk away.
Texas HVAC Replacement Cost is a free introduction service operated by Ellul Solutions Ltd; we pass your details to HVAC contractors covering your ZIP code, who quote you directly. We may receive a fee from providers; you pay nothing and are under no obligation. We are not contractors and we are not affiliated with the EPA, the US Department of Energy or the Texas Department of Licensing and Regulation. Nothing here is engineering, legal or code-compliance advice: confirm permit requirements with your local building department, verify any contractor license with TDLR, and re-check refrigerant dates at epa.gov, because those rules have changed repeatedly.
What moves a Texas HVAC replacement quote, 2026
Last updated
Texas quotes are set by a cooling load that runs for most of the year, a heating requirement that the state stopped treating as optional after February 2021, and duct systems that mostly live in unconditioned attics. Add licensing and permit rules that are genuinely different from neighboring states and you get a table of drivers, not a price.
Cost-driver table, not a price table. We publish no dollar range for Texas because an honest one does not exist across a state that runs from the Panhandle to the Gulf: tonnage, equipment type, duct condition and location, electrical work, permit costs and access dominate, and they differ by hundreds of miles. The regulatory drivers below are sourced to the EPA, 10 CFR 430.32 and Texas TDLR and were checked on 2026-08-14. Take the last column with you to every quote appointment.
| Cost driver | Why it moves the price | What to ask for in writing |
|---|---|---|
| Climate zone and load | A house in Amarillo has a real heating season and a dry cooling load. A house in Houston has a huge latent load and a mild winter. El Paso is different again. The same equipment is the wrong answer in at least two of the three. | A written Manual J load calculation using your actual design conditions |
| Heating strategy after 2021 | The February 2021 winter storm changed how Texans price the heating side. Heat pump plus backup, dual fuel, or a gas furnace are different capital costs with different running costs and different behavior in a hard freeze. | The heating capacity at your design low temperature, and what the backup is |
| Duct condition and attic location | Most Texas duct runs sit in attics that reach extreme temperatures. Leakage there is not just wasted air, it is wasted capacity on the hottest day. This is where two quotes for the same house separate. | Measured duct leakage, and duct work priced as its own line |
| Equipment type and staging | Single stage, two stage, or variable speed. In humid east Texas the staging is a comfort decision as much as an efficiency one. In dry west Texas the hot-day capacity matters more. | Why this staging was chosen for your climate, in one paragraph |
| Refrigerant generation | New residential systems must use refrigerant under 700 GWP, so R-454B and R-32 are what is installed now. Pre-2025 R-410A stock may still be legally offered and should not be priced as current equipment. | Refrigerant, model numbers, and whether the unit is pre-2025 inventory |
| Efficiency floor | Texas is in DOE's Southeast region, so the installed minimum for a split AC is above the national manufacturing minimum. Buying above the floor costs more up front and pays back over a long cooling season. | Payback math using your own utility rate and your own run hours |
| Electrical work | Heat pump conversions, larger air handlers and heat strips can require a new circuit, a disconnect or a panel upgrade. It is a separate trade and often a separate permit. | Whether electrical upgrades are included or excluded |
| Licensing and permits | Work must be done under a TDLR air conditioning and refrigeration contractor license, and cities still charge building permit fees even though they can no longer charge registration fees to licensed contractors. | The TDLR license number, who pulls the permit, and the permit fee as a line item |
| Access and exclusions | Attic installs in August, tight crawl spaces, crane lifts, plus commonly excluded items such as line sets, pads, thermostats, disposal and drywall repair. | A written exclusions list, then compare bids on identical scope |
- Texas sits in the Department of Energy's Southeast region for central air conditioner standards, so a split-system air conditioner installed in Texas must meet 14.3 SEER2 under 45,000 Btu/h or 13.8 SEER2 at 45,000 Btu/h and above, against a national manufacturing minimum of 13.4 SEER2 (10 CFR 430.32(c)(5) and (c)(6)).
- A TDLR Class B environmental air conditioning endorsement covers systems up to 25 tons cooling capacity or 1.5 million Btu per hour heating output; a Class A endorsement has no size limit (Texas Department of Licensing and Regulation).
- Since September 1, 2021 Texas Occupations Code Section 1302.304 prohibits a municipality from charging registration fees to TDLR-licensed air conditioning and refrigeration contractors, but does not prevent municipalities from collecting building permit fees (TDLR ACR FAQs).

The detail
Each one cites where its numbers come from.
- Texas HVAC replacement cost: what sets your number
Why Texas HVAC quotes vary so much: climate zone, attic duct condition, heating strategy after 2021, the Southeast SEER2 floor, electrical work and permits.
- Heat pump or gas furnace in Texas after the 2021 freeze
Texas heating stopped being an afterthought in February 2021. How heat pumps, dual fuel and gas furnaces compare on capital cost, running cost and hard freeze behavior.
- R-410A, R-454B and what the change means in Texas
New US residential AC and heat pumps must use refrigerant under 700 GWP from January 2025. What that changes about repairing an older Texas system, and what it does not.
- TDLR licensing and permits for Texas HVAC work
Texas HVAC work needs a TDLR air conditioning and refrigeration license. Class A and B, the 25 ton limit, the 2021 municipal fee rule, and permits that still apply.
Frequently asked
How much does HVAC replacement cost in Texas?
There is no honest single figure across a state this size, so this site publishes cost drivers rather than an invented average. Your number comes from climate zone and load, heating strategy, duct condition in the attic, equipment type and efficiency, electrical work, permits and access. Compare three quotes on one identical scope.
What SEER2 is required in Texas?
Texas is in the Department of Energy's Southeast region, so a split-system air conditioner installed here must meet 14.3 SEER2 below 45,000 Btu/h or 13.8 SEER2 at 45,000 Btu/h and above. The national manufacturing minimum is 13.4 SEER2, and split-system heat pumps meet a national 14.3 SEER2 with 7.5 HSPF2.
Does a Texas HVAC contractor need a license?
Yes. TDLR requires contractors who install, repair or maintain air conditioning, refrigeration or heating systems to hold a TDLR license, with an environmental air conditioning endorsement in Class A (any size) or Class B (up to 25 tons cooling or 1.5 million Btu per hour heating). Ask for the license number on the written proposal.
Should I get a heat pump in Texas after the 2021 freeze?
It is worth pricing, and so is dual fuel. The useful questions are the heating capacity at your design low temperature, what the backup heat is and what it costs to run, and the changeover temperature on a dual fuel proposal. In south Texas a straight heat pump usually wins; in north Texas and the Panhandle dual fuel earns its extra cost.
Is R-410A still allowed in Texas?
Existing R-410A systems remain serviceable: EPA states components used to repair existing systems are not subject to the Technology Transitions restrictions. New residential systems must use refrigerant under 700 GWP, and a May 2026 EPA final rule allows equipment manufactured or imported before January 1, 2025 to continue being installed.
Is this quote service really free?
Yes, free to you and with no obligation to accept any quote. We pass your details only to HVAC contractors covering your ZIP code, who quote you directly. We may receive a fee from those providers, which is how the service is funded.
