A call goes faster when you can name the problem in a sentence. This page gathers every HVAC service in Houston, TX that the line takes calls about, with what each one covers and a link to its full page.
Houston Air & Heating never visits your home. Phone (832) 662-4107, let the automated assistant know if it is a heating or a cooling problem, which part of the area you are in and what you are seeing, and it hands your call to a locally owned, independent company that does the work. Those companies handle HVAC repair services in Houston, TX and the suburbs around it, and they set their own prices. Use the descriptions below to pick the right words, or skip straight to the table that matches symptoms to pages.

Cooling services
In a city where summer afternoons sit in the mid 90s for weeks, cooling problems are the most urgent ones. Cooling work splits into four kinds of visit.
AC repair
A system that blows warm, short cycles (turns on and off every few minutes), freezes up or will not start. A careful technician tests before replacing anything: electrical readings on the capacitor and contactor, refrigerant pressures, airflow and the condensate drain. See AC repair in Houston.
Air conditioning repair, part by part
If you want to understand the parts that wear out in Gulf Coast humidity, from coils to blower motors, and how each repair is done, the air conditioning repair page covers them one at a time.
Emergency and after-hours AC repair
For a house that is heating up overnight, an older relative or a baby at home, or a system that quit after a storm knocked out power. The line answers at any hour; what the company charges for a night or weekend visit is up to the company, so ask. See emergency AC repair.
AC installation and replacement
A new system should be sized by a load calculation of your house, not by the size of the old unit. A complete quote names the equipment model numbers, the efficiency rating, what happens to the ductwork and who pulls the permit. Inside Houston city limits, the Houston Permitting Center requires a mechanical permit for installing or replacing a condensing unit, followed by a city inspection. See AC installation in Houston.
Heating services
Houston homes heat in two main ways: a gas furnace, usually in the attic or a closet, or electric heat, either a heat pump or resistance heat strips in the air handler. They fail differently, so they have separate pages.
Furnace repair
A gas furnace that clicks but will not light, lights and shuts off, or fills the house with a burning smell on its first run of the season. Burners, gas valves and flue venting are technician work only. See furnace repair in Houston.
Heating repair: heat pumps and electric heat
A heat pump that blows cool air in heat mode, runs on emergency or auxiliary heat all night, or ices over and never defrosts. See heating repair.
Smell gas? Leave the house without flipping switches, then call 911 and the gas utility's leak line from a safe distance. If a carbon monoxide alarm sounds, get everyone outside and call 911.
Maintenance and commercial systems
HVAC tune-up and maintenance
A spring cooling check and a fall heating check catch weak parts, dirty coils and slow drains before they turn into a breakdown. The tune-up page explains how often to book one, and is a tune-up worth it weighs the evidence.
Commercial HVAC
Rooftop package units, split systems in offices and shops, and the cooling a restaurant kitchen needs. Commercial work is a different scale, and Texas license classes reflect it. See commercial HVAC in Houston.
Every service page
The same services as cards, if you would rather browse.
AC Repair in Houston
Warm air, a unit that hums but will not start, ice on the lines or a tripped breaker. How a careful diagnosis works in Houston heat and what to ask before you approve a repair.
Air Conditioning Repair
The parts of a central air system that wear out in Gulf Coast heat and humidity, what each repair involves, and when a repair stops making sense.
Emergency AC Repair (24/7)
No cooling at night, on a weekend or during a heat wave or power outage. What to do while you wait and who is most at risk.
AC Installation and Replacement
Why a load calculation matters more than the brand, what a complete replacement quote lists, and permits in Houston.
Furnace Repair
Gas furnace not lighting, short cycling or smelling hot on the first cold front. Gas and carbon monoxide safety first, then what a technician checks.
Heating Repair (Heat Pumps and Electric Heat)
Heat pumps blowing cool air, aux heat running all night, electric heat strips that quit. How Houston homes heat and what goes wrong before a freeze.
HVAC Tune-Up and Maintenance
How often to service an AC and furnace on the Gulf Coast, when to book it, and the filter and drain habits that matter most in humid heat.
Commercial HVAC
Rooftop units, offices, shops and restaurants. How commercial AC repair differs from residential and what to ask a commercial contractor.
Guides that go with these services
Before you approve a big repair or a new system, these answer the questions most people have: what things cost, whether to repair or replace, and how to pick a company.
How Much Does AC Repair Cost?
Published cost ranges for common AC repairs, what pushes a Houston bill up or down, and how to read a quote.
Repair or Replace Your AC or Furnace?
Age, repair cost, refrigerant and efficiency: a plain way to weigh fixing an old system against replacing it.
Is an HVAC Tune-Up Worth It?
What the evidence says about yearly maintenance, who gains the most from it and when you can skip it.

What the line does not take calls about
The same phone number also handles Houston roofing and pressure washing calls, which is why the assistant asks what you need first. On this site, though, the subject is heating and cooling only. These jobs belong to other trades:
- Plumbing, including water heaters, drains and gas piping to appliances. The water heater guide explains who to call.
- Electrical work beyond the HVAC equipment itself, such as panel upgrades or new circuits.
- Duct cleaning sold as a separate service. Duct repair and sealing that is part of an HVAC job is a question for the HVAC company.
- Roofing and pressure washing are not covered on this site.
- Appliance repair: refrigerators, washers, dryers and ovens.
Before you approve any work
The companies you reach are independent businesses. You decide whether to hire them, and you are free to get a second quote. Ask for the diagnosis in plain words, the price in writing and the company's Texas license number.
Verify the license before work begins. Texas requires anyone contracting to do air conditioning, refrigeration or heating work to hold an Air Conditioning and Refrigeration (ACR) Contractor license from the Texas Department of Licensing and Regulation (TDLR). Ask the company for its ACR license number, then confirm it on the TDLR license search (opens in a new tab). The line does not check this for you.
- Dial the numberAn automated assistant picks up (832) 662-4107 at any hour and asks what you need help with.
- Say what is wrongTell it whether the trouble is cooling or heating, where in the Houston area you are, and what the system is doing.
- Reach a local companyYour call is transferred to an independent, locally owned HVAC company, which gets a short summary of your problem before it answers.
- Work it out with themThat company inspects, quotes, repairs and bills you directly. If nobody can pick up, your name, number and problem are passed on for a call back.
