HVAC Contractors in Houston, TX

Houston is one of the most demanding HVAC markets in the United States — not just because of the heat, but because of the combination. The city's humid subtropical climate produces heat index values that regularly exceed 105°F from May through September, with overnight lows staying above 80°F during peak heat waves. AC systems in Houston run nearly year-round. They have to manage both temperature and moisture simultaneously. The result is an environment that wears out equipment faster and makes contractor selection more consequential than in almost any other US city.

This directory lists HVAC contractors serving Houston and the Greater Houston metro, including The Woodlands, Katy, Sugar Land, Pearland, Cypress, Tomball, Spring, Humble, Pasadena, and Baytown. All listings use public business information. Texas HVAC license numbers are shown where provided. Unclaimed profiles are clearly labeled — no contractor has paid to appear here.

HVAC guide for Houston

Houston HVAC planning starts with the cooling load. The National Weather Service's Houston airport climate normals document hot summers and a milder winter season. Before warm weather, test cooling and have airflow, coils, and condensate drainage checked if performance has changed. Test heat before cooler weather as well; ask for a checklist suited to the actual heater rather than assuming the home has a particular fuel or system. A replacement proposal should explain both temperature control and moisture removal, along with the condition of existing ducts.

The Houston Permitting Center's homeowner mechanical permit application identifies the mechanical/HVAC permit process. Confirm the requirements for the property and work scope, including who will obtain approval and arrange inspection. Texas requires contractors who install, repair, or maintain air-conditioning, refrigeration, or heating systems to hold a TDLR Air Conditioning and Refrigeration Contractor license. Verify the license status and that its class and endorsement cover the proposed work before hiring. Review TDLR's air-conditioning contractor information and use its license search before hiring.

CenterPoint Energy's Houston heating and cooling programs include ComfortCheck tune-ups and replacement incentives for eligible residential Houston Electric customers. Central air conditioners, heat pumps, and mini-splits can qualify for replacement incentives through participating contractors. Confirm the account, equipment, and participation requirements before ordering; the tune-up offer excludes apartments and has its own eligibility rules. Compare the written installation scope, equipment specifications, and startup testing plan before choosing a proposal.

5 Things to Check Before Hiring a Houston HVAC Contractor

1. Verify the Texas TDLR HVAC license

Texas requires contractors who install, repair, or maintain air-conditioning, refrigeration, or heating systems to hold a TDLR Air Conditioning and Refrigeration Contractor license. Verify the license status and that its class and endorsement cover the proposed work before hiring. Texas TDLR license search.

2. Ask specifically about humidity control — not just cooling

Houston's humidity is the variable that separates a good HVAC job from a bad one. An oversized system cools fast but short-cycles, leaving the air damp and uncomfortable. Proper sizing for Houston requires a Manual J load calculation that accounts for latent heat load — the moisture content of the air — not just sensible temperature. Ask your contractor explicitly how they size for humidity.

3. Confirm the condensate drain plan

Houston's humidity means AC systems pull enormous amounts of water from the air — a properly functioning system may remove 5–10 gallons per day from the home. Condensate drains are the most common maintenance failure point in Houston. Ask about drain pan material, secondary drain lines, and whether a condensate overflow safety switch will be installed.

4. Verify mechanical permit is included for replacements

Harris County and the City of Houston require mechanical permits for HVAC replacements. The licensed contractor pulls the permit — if they suggest skipping it to save time or money, that is a red flag. Unpermitted work creates problems at time of sale and can void manufacturer warranties.

5. Schedule spring maintenance in February — not April

Houston's cooling season starts earlier than most US cities, and contractors are fully booked by late March through September. A February tune-up catches issues before the heat arrives and secures faster scheduling. A system that has sat through a mild Houston winter may have dirty coils, a low refrigerant charge, or a failing capacitor that's not obvious until the first 95°F day of May.

Frequently Asked Questions — Houston HVAC

How much does AC repair cost in Houston, TX?
AC repair in Houston typically runs $150–$500 for a standard service call. The combination of heat and humidity means compressors and capacitors in Houston wear faster than national averages. Common costs: capacitor replacement $150–$350; refrigerant recharge $200–$500; compressor $1,400–$2,800. Emergency and after-hours calls carry a 25–50% surcharge. Schedule spring maintenance in February to catch issues before peak season.
What HVAC license is required in Texas?
Texas requires contractors who install, repair, or maintain air-conditioning, refrigeration, or heating systems to hold a TDLR Air Conditioning and Refrigeration Contractor license. Verify the license status and that its class and endorsement cover the proposed work before hiring.
Why does Houston HVAC maintenance matter more than in other cities?
Houston's HVAC systems handle both temperature and humidity simultaneously — the latent heat load is among the highest of any US city. Coils, condensate drains, and drain pans foul faster than almost anywhere else in the country. Skipping annual service in Houston shortens equipment life noticeably and increases the risk of indoor air quality problems from mold and moisture in the system.
When should I replace my Houston HVAC system?
Consider replacement when the system is 12–15+ years old, repairs exceed 50% of replacement cost, or it uses R-22 refrigerant (phased out 2020). Houston's near-year-round cooling demand means high-efficiency equipment pays back quickly — a 15-SEER2+ system vs. an aging 10-SEER unit can cut cooling costs 30–40% on CenterPoint Energy rates.
Is a heat pump a good choice for Houston?
Yes. Houston's mild winters (average January lows around 45°F) make heat pumps highly efficient — backup electric heat strips rarely engage. The key requirement: choose a unit rated for Houston's extreme summer ambient temperatures and confirm the contractor has experience sizing heat pumps for high-humidity climates. Moisture management is as important as temperature management in the Houston market.

HVAC in Houston — What to Know

The Greater Houston metro is home to more than 7 million people and is the fourth-largest US city proper by population. Its climate sits firmly in the hot, humid subtropical zone — Houston's summers are longer and more humid than Dallas or San Antonio, making air conditioning essential from early April through late October most years.

Check Texas contractor licensing. Texas requires contractors who install, repair, or maintain air-conditioning, refrigeration, or heating systems to hold a TDLR Air Conditioning and Refrigeration Contractor license. Verify the license status and that its class and endorsement cover the proposed work before hiring. Texas TDLR license search.

Humidity is the defining challenge. Houston's air conditioning systems carry one of the highest latent heat loads in the United States. Proper sizing requires a contractor who performs Manual J load calculations — not square-footage rules of thumb. An oversized system short-cycles, fails to dehumidify adequately, and causes elevated indoor humidity that can promote mold growth in Houston's climate.

Book before the heat arrives. Houston HVAC contractors are at peak demand from April through September. A February or early March tune-up catches issues before the heat wave season and secures faster scheduling. Waiting until the first hot spell typically means a 1–2 week wait for a non-emergency appointment.
