Common Houston HVAC emergencies
Call Now — (844) 582-179524/7 dispatch · Houston-area network
AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. The most common cause is electrical (capacitor, contactor) or refrigerant — both require a technician.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building immediately and call 911 first.
Water dripping from vent or air handler
Water from a ceiling vent · pooling near the indoor air handler · drain pan overflowing. The #1 cause in humid Houston summers is a clogged condensate drain line — clearing it requires working around the evaporator coil and is a technician task.

Houston's hot-humid climate & your HVAC
This is a strongly cooling-dominated Zone 2A (Hot-Humid) climate — AC runs 8–10 months of the year and humidity management is a year-round design consideration. Federal SEER2 14.3 (Southeast Region) minimum applies to new equipment.

HVAC in Houston, TX: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Texas licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Houston George Bush Intercontinental Airport (KIAH) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00012960), Houston records an annual mean temperature of 70.5°F, approximately 3,287.7 annual cooling degree days against only 1,266.1 heating degree days, and a striking 51.84 inches of annual precipitation. The 2.6:1 CDD-to-HDD ratio and sub-inch annual snowfall define Houston as a strongly cooling-dominated Zone 2A hot-humid climate where the AC system runs 8–10 months of the year and high dew points make dehumidification a year-round design consideration rather than a summer-only concern.
U.S. Census ACS 2022 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Houston city, Texas) report 916,536 occupied housing units — one of the largest municipal housing stocks in the country — with a median year built of 1981. Heating-fuel distribution contradicts the typical “Texas means gas” assumption: 64.5% electricity (591,293 units) dominates, with only 33.2% utility natural gas (304,650 units). The electric-heat dominance reflects Houston’s short heating season (just 1,266 HDD per year) and the prevalence of heat-pump systems that serve both the heating and cooling loads from a single piece of outdoor equipment. For 600,000+ Houston homes, the heat pump isn’t an upgrade — it’s already the status quo.
Texas Dept. of Licensing & Regulation
Every HVAC contractor working in Houston must hold a current Air Conditioning and Refrigeration (ACR) Contractor license issued by the Texas Department of Licensing and Regulation (TDLR). The licensing program is governed by Texas Occupations Code Chapter 1302 (the Air Conditioning and Refrigeration Contractors Law) and Texas Administrative Code Title 16 Chapter 75 (the implementing administrative rules). Texas ACR licenses are issued in two classes distinguished by permitted equipment size — residential/light-commercial contractors typically hold one class and large-commercial contractors hold the other. Verifying a contractor’s active TDLR license before authorizing work is the baseline due-diligence step for every Houston homeowner; TDLR publishes a public license-lookup tool at tdlr.texas.gov.
DSIRE Database (NCSU + DOE)
Houston’s electricity distribution is handled by CenterPoint Energy (the Transmission and Distribution Utility), but retail electricity service is provided by a Retail Electric Provider (REP) chosen by the consumer under the Texas deregulated market. That means residential HVAC rebates in Houston are typically administered by your chosen REP, not by CenterPoint directly. The most reliable way to see current rebate dollar amounts is the ENERGY STAR Rebate Finder (EPA) filtered to your Houston ZIP code, or the DSIRE database for Texas residential incentives. Permit fees for residential mechanical work are set by the Houston Permitting Center (Mechanical Section, 832.394.8850); contact the center directly for the current fee schedule as amounts are updated periodically. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21) — the local incentives above remain active for 2026.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). State HEAR rebates and utility programs remain in effect. See our HVAC financing options for what's still available.
