AC Repair
AC repair cost depends on the failing part and whether the system is low on refrigerant, electrical, or mechanical. Common fixes — capacitors, contactors, fan motors, refrigerant recharges — land between $150 and $1,500 including labor, while a failed compressor runs higher.
View Houston pricing →Furnace Repair
Furnace repair cost depends on the failing part and whether the unit is gas or electric. Common fixes — flame sensors, igniters, blower motors, control boards — land between $150 and $1,800 including labor, while a cracked heat exchanger runs higher.
View Houston pricing →AC Installation
AC installation cost covers the equipment and labor to fit a new system — whether it's a like-for-like central AC replacement, a first-time install with new ductwork, or a ductless mini-split. The number swings with tonnage, SEER2 efficiency tier, and duct condition.
View Houston pricing →AC Maintenance
AC maintenance — a seasonal tune-up — keeps the system running efficiently and catches small faults before they become summer breakdowns. A single visit runs $75–$200; annual plans that bundle a spring AC and fall heating check cost a bit more.

With a median home built in 1980, many Houston AC and furnace systems are at or past their 12–15 year lifespan — a common reason replacements spike here.
HVAC cost in Houston.
Homes in Houston were built around 1980 on average — roughly 46 years ago. Because a central AC or furnace typically lasts 12–18 years, a large share of Houston systems are now at or past the point where another repair stops paying off and replacement becomes the smarter spend.
Houston sits in a Hot-humid (IECC zone 2A) climate — Summer design ~96°F at high humidity; long cooling season. Houston’s enemy isn’t just heat, it’s humidity. A variable-speed or two-stage system runs longer at lower output, which pulls far more moisture out of the air than a cheap single-stage unit that blasts cold and shuts off. Because natural gas is inexpensive here, many homes pair a high-SEER2 AC with a gas furnace rather than going all-electric heat pump. That makes system type and sizing matter more here than the sticker price alone.
Local labor rates and Texas permitting shape the final number. Based on area incomes and cost tier, Houston installs tend to land slightly above the national average — the cost table below is adjusted to match.
| Type / job | Typical Houston cost |
|---|---|
| AC repair (common fault)Capacitor, refrigerant, fan motor | $150 – $1,600+ |
| Furnace repair (common fault)Igniter, flame sensor, blower | $150 – $1,950+ |
| Central AC (replace, like-for-like)Existing ducts in good shape | $4,300 – $8,600+ |
| Heat pump (cooling + heating)Qualifies for federal & utility rebates | $5,400 – $13,000+ |
| Ductless mini-splitNo ducts; single or multi-zone | $3,200 – $8,600 |
| AC tune-up / maintenanceSeasonal service visit | $80 – $225 |
| Permit & inspectionRequired in most jurisdictions | $80 – $425 |
Installed prices including labor. Code upgrades, ductwork, and higher-tonnage or higher-SEER2 systems move the number up.
What’s different about Houston.
Generic cost pages skip the things that actually decide your price and which system fits here — local code, climate, and the money you can claim back.
Climate & cooling load
Cooling-dominant and humid — the AC runs most of the year and humidity control matters as much as raw temperature. Winters are short and mild, with cheap natural gas heat.

Recommended unit for Houston
In hot, humid Houston the priority is moisture control, so a variable-speed or two-stage AC that runs long, low cycles is the practical pick — it keeps the house from feeling clammy in a way a cheap single-stage unit can’t. With cheap gas heat, pairing that AC with a gas furnace keeps winter costs down. A heat pump also runs well in the mild winters and earns the bigger federal credit if you’d rather go all-electric.

What Houston code requires
Houston requires a mechanical permit and follows the International Residential/Mechanical Code. No seismic rules here — the details are driven by heat, humidity, and the area’s cheap natural gas:
- PermitRequired
Mechanical permit pulled by your TDLR-licensed HVAC contractor through the City of Houston permitting center.
- Manual J load calcRequired for sizing
In humid Houston an oversized unit cools the air but never wrings out the humidity — right-sizing is what keeps the house from feeling clammy.
- SEER2 minimum14.3 SEER2 (South region)
Federal South-region minimum for split-system AC; variable-speed higher-tier units handle humidity far better.
- RefrigerantR-454B / R-32 (2025+)
New systems use low-GWP refrigerant as R-410A is phased down.
- Condensate & drainSecondary drain / float switch
High humidity means heavy condensate — code expects a secondary drain or overflow float switch to prevent ceiling damage.

Money back in Houston
Houston runs on low-cost natural gas, so the rebate path depends on whether you go heat pump or AC + gas furnace:
- UtilityvariesCenterPoint Energy efficiency rebates →
Rebates for qualifying high-efficiency cooling and heat-pump equipment installed by a participating contractor.
- Federal30% of cost, up to $2,000Federal 25C — heat pump →
For a qualifying ENERGY STAR heat pump.
- Federal30% of cost, up to $600Federal 25C — central AC →
