What does heat pump replacement cost in Houston?

The installed cost of a new heat pump in Houston depends on the capacity your home needs, the efficiency ratings and compressor type you choose, the backup heat and electrical work the system requires, and how much installation work your attic, ducts and line set add. A heat pump does both jobs, cooling all summer and heating in winter, so the quote covers more equipment decisions than an AC-only replacement.

This guide does not publish a current price. A national figure cannot see your attic, your electrical panel or your ductwork, and it can set the wrong expectation in either direction. Instead, it explains each factor that moves the price, which ones move it a little and which ones a lot, and what a complete written quote should include so you can compare offers fairly.

The honest answer to "what does a heat pump cost?" is: it depends on the size, efficiency and installation complexity of your system, and the only reliable number is an itemized quote written after an on-site look at your home.

If you are still deciding whether a heat pump is the right system for you at all, start with how a heat pump works in Houston's climate and our comparison of a heat pump vs. an AC with a gas furnace.

What drives the installed price of a new heat pump?

Capacity, efficiency ratings, compressor type, backup heat and the amount of installation work are the main drivers of an installed heat pump price. The table below lists the common factors and how each one tends to affect a quote.

What drives the installed price of a heat pump replacement in Greater Houston

Factor	What it means	Effect on the installed price
System size (tonnage)	Capacity, set by a load calculation for your home	Larger systems raise the price; correct sizing can lower it if the old unit was oversized
Efficiency (SEER2 and HSPF2)	Cooling and heating efficiency ratings; the federal minimum for split heat pumps is 14.3 SEER2 and 7.5 HSPF2	Each step above the minimum raises the equipment price; it can lower operating costs over time
Compressor type	Single-stage, two-stage or variable-speed	Two-stage raises the price; variable-speed can raise it sharply
Indoor unit	New air handler matched to the outdoor unit, or reuse of the existing one	A new air handler raises the price but is usually needed for a certified match
Backup heat strips	Electric resistance heat in the air handler for cold snaps and defrost	Usually small for the strips themselves; a larger heat-strip size can raise the electrical cost
Converting from AC + furnace	Switching from gas heat to a heat pump system	Can raise the price sharply if new electrical service, an air handler or gas-line capping is needed
Attic access	How hard it is to reach and work on the air handler	Tight, hot or hard-to-reach attics raise labor
Refrigerant line set	The copper lines between the indoor and outdoor units	Reusing a suitable line set is usually small; replacing a long or inaccessible one raises the price
Electrical	Disconnect, breakers and wiring for the outdoor unit and the heat strips	Usually small if existing circuits fit; panel or wiring upgrades raise it
Ductwork	Repairs, sealing, resizing or replacement	Minor sealing is usually small; replacing or redesigning ducts can raise the price sharply
Thermostat	A control that manages heat pump stages, defrost and backup heat	Usually small, but a heat pump needs a compatible thermostat
Permit, pad, removal	Mechanical permit where required, outdoor pad, recovery and haul-away of old equipment	Usually small, but each should be listed

Which Houston-specific factors change the price?

Sizing for humidity, attic air handlers, the regional efficiency standard and the refrigerant transition are the local factors that most often change a Houston heat pump quote.

Sizing for cooling and humidity first

In Houston, a heat pump spends most of its life cooling: NOAA's 1991–2020 normals for Houston Intercontinental Airport show about 3,288 cooling degree days a year against 1,266 heating degree days. The professional standard for sizing is an ACCA Manual J load calculation. An oversized heat pump cools quickly and shuts off before it removes much moisture, leaving the house clammy. Correct sizing protects comfort and can lower the equipment price.

Attic air handlers

Most Greater Houston heat pumps use an air handler in the attic. Summer attic work is slower, and the condition of the platform, drain pan and condensate line all affect the scope. A quote that assumes easy access is a different job from one that accounts for a cramped attic.

The SEER2 and HSPF2 minimums

Under the U.S. Department of Energy standards that took effect in 2023, new split-system heat pumps must meet at least 14.3 SEER2 and 7.5 HSPF2. Every quote should meet that floor; the price question is how far above it you go. Our guide to SEER2 ratings explained covers what the numbers mean.

Refrigerant: R-410A, R-32 and R-454B

Under the EPA's technology-transition rules, new residential split systems manufactured from 2025 use lower-global-warming-potential refrigerants such as R-32 and R-454B. Goodman's current residential split systems use R-32. In a final rule published May 26, 2026, the EPA removed the earlier installation deadline for qualifying R-410A equipment, so units manufactured before 2025 may still be installed until they are used up; legal challenges to that rule are pending. Ask which refrigerant a quote uses, because it affects the matched air handler and whether the line set can be reused. Some A2L installations also require a refrigerant leak-detection sensor. See the refrigerant change explained for background.

Do permits affect the cost of heat pump replacement?

A permit adds a fee and an inspection step in the cities that require one, and the fee is usually a small part of the total. This is general guidance, not legal advice; confirm the current rules with your local building department.

• The Houston Permitting Center requires a mechanical permit for HVAC alterations, including condensing-unit replacement.
• The City of Sugar Land requires a permit for HVAC repair, replacement or addition, and doubles the fee if work starts before the permit is issued.
• The cities of Katy, Pearland, Missouri City, Pasadena, Jersey Village and Humble also issue mechanical permits for HVAC work.
• In unincorporated areas such as Spring, Aldine, Cinco Ranch, Fresno and The Woodlands, no county residential mechanical permit was found; the state code standard in 16 TAC §75.100(e) still applies.

Our Greater Houston HVAC permit guide has a city-by-city table. Whatever your city, the quote should say whether a permit is included and who is responsible for it.

Are there rebates, tax credits or financing for a heat pump?

CenterPoint Energy offers incentives on qualifying high-efficiency installations through participating contractors, the federal 25C tax credit has ended, and financing is the main remaining way to spread the cost.

• CenterPoint Energy incentives: CenterPoint's residential heating and cooling program pays incentives through participating contractors, and CenterPoint says the amount may increase depending on your installation. Ask your contractor which models qualify and whether they participate. Our CenterPoint rebates guide has the details.
• Federal tax credit: The Section 25C credit, which covered qualifying heat pumps, does not apply to property placed in service after December 31, 2025. See HVAC tax credits in 2026.
• Financing: Financing is available through FTL Finance, subject to credit approval.

What makes heat pump quotes hard to compare?

Heat pump quotes are hard to compare when they describe different jobs under the same name, so the lowest total is not always the lowest price for the same work. Watch for these gaps:

• Different scope. One quote includes a new matched air handler and heat strips; another reuses the old air handler.
• A mismatched system. A new outdoor unit on an old air handler may never reach its rated SEER2 and HSPF2 and may not suit a different refrigerant. Look for an AHRI-certified matched combination.
• Unstated backup heat. The heat-strip size affects both winter comfort and the electrical work. A quote that omits it is incomplete.
• Sizing by guesswork. No load calculation often means copying the old tonnage.
• Missing line items. Line set, electrical, pad, drain work, permit and disposal can be left off a low quote and added later.
• Unclear warranty terms. Manufacturer parts coverage and installer labor coverage are separate. Ask what each covers, for how long, and whether registration is required.

What should a written heat pump quote include?

A complete written heat pump quote names the exact equipment and lists every part of the job separately. Ask for:

1. Equipment model numbers for the outdoor unit and the air handler, plus the AHRI reference number for the matched combination so you can check it in the AHRI Directory.
2. Size and ratings: tonnage, certified SEER2 and HSPF2 of the matched system, and the refrigerant.
3. Backup heat: the heat-strip size and the circuit it needs.
4. How the size was chosen: whether a Manual J load calculation was done.
5. Labor, including attic work.
6. Removal and disposal of the old equipment, including refrigerant recovery.
7. Permit: whether one is included where your city requires it.
8. Refrigerant line set: reused or replaced, and why.
9. Pad or stand for the outdoor unit.
10. Electrical: disconnect, breakers and wiring changes.
11. Thermostat: included or not, and heat pump compatible.
12. Ductwork changes, described specifically.
13. Warranty terms: parts, labor and any registration requirement.

To compare quotes apples-to-apples, line them up on those items. Where one quote includes something another does not, ask the second contractor to price it. Compare matching efficiency and compressor type before comparing totals. When the scopes match, the price difference is real.

Frequently Asked Questions

Why doesn't this guide give a current heat pump price?

An installed heat pump price depends on your home's load calculation, the equipment tier, the backup heat and the installation work, none of which a website can see. Current pricing comes from an on-site estimate.

Does a heat pump cost more to install than an AC?

A heat pump replaces both your cooling and your heating, so the scope differs from an AC-only replacement. Converting from an AC with a gas furnace can add an air handler, heat strips and electrical work. Compare complete, itemized quotes for each option rather than equipment prices alone.

What efficiency does a new heat pump need in Texas?

Under the 2023 DOE standards, new split-system heat pumps must meet at least 14.3 SEER2 and 7.5 HSPF2. Higher ratings usually raise the equipment price and can lower operating costs over time.

Can I still buy an R-410A heat pump in 2026?

Possibly. The EPA's final rule published May 26, 2026 removed the earlier installation deadline, so qualifying R-410A equipment manufactured before 2025 may still be installed until it is used up; legal challenges are pending. Newer systems use R-32 or R-454B. Ask which refrigerant any quote uses.

Is there a tax credit for a heat pump in 2026?

No. The Section 25C credit does not apply to property placed in service after December 31, 2025. CenterPoint Energy incentives may apply to qualifying equipment through participating contractors, and financing is available through FTL Finance, subject to credit approval.

Do I need a permit to replace a heat pump?

Many Greater Houston cities, including Houston, Sugar Land, Katy and Pearland, issue mechanical permits for HVAC replacement. Rules differ in unincorporated areas. This is general guidance; confirm with your local building department and check whether your quote includes the permit.
