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. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
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 right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Water dripping from vent or air handler
Water from a ceiling vent · pooling near the indoor air handler · drain pan overflowing. Typical causes of condensate overflow include a clogged or dislodged drain line, a cracked or corroded drain pan, a failed condensate pump, and a dirty filter that lets the coil freeze (ACCA). Turn the thermostat off to limit water damage and call a technician.

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 high dew points make dehumidification a year-round design consideration rather than a summer-only concern.
U.S. Census ACS 2023 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 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). Houston’s short heating season (about 1,266 HDD per year) keeps heating loads small. Electric heat in the Census tables includes both heat pumps and electric-resistance systems.
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. CenterPoint itself offers residential HVAC incentives: per its heating and cooling incentives page, incentives “start at $200 and may increase, depending on your installation,” cover central A/C, heat pump and mini-split systems rated 15.2 SEER2 or higher, and are applied directly to the installation invoice when you work with a participating contractor. To compare other current rebates, use 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 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). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
