What Houston Air & Heating is
Two things: a phone number that answers at any hour, and a website that explains heating and cooling problems in plain words.
Dominion Digital Group operates Houston Air & Heating under that name as a d/b/a. When you call, an automated assistant asks what you need, asks briefly what is going on with your heating or air conditioning, and hands your call to an HVAC company in the Houston area that is independent and locally owned. If that company cannot pick up, your name, number, area and problem are passed along so it can call you back.
That is the whole service. The company you reach does the inspecting, the quoting and the work, and you pay that company directly.
What it is not
It is not a contractor. It does not employ technicians, own vehicles or hold a Texas heating and air conditioning license, and it never diagnoses, repairs, installs, services, quotes or schedules anything. It does not vouch for the companies it connects you with. This site never describes them as insured, certified or rated, because the line does not check those things. What it does do is show you how to check the one thing Texas law requires of them: a state Air Conditioning and Refrigeration contractor license, issued by TDLR (the Texas Department of Licensing and Regulation).
You may have known this site by a different name. The name now matches the web address, houstonairandheating.com, so that what you search for, what you type and what you see all line up.
Why one free line helps
Finding heating and air help in a hurry usually means scrolling past ads, calling companies that do not serve your side of town, and leaving messages. The line is built to shorten that.
It costs you nothing
Calling and being transferred are free. The line never bills you, and you pay only for work you agree to with the company.
It answers around the clock
The automated assistant picks up at every hour, every day of the year, nights, weekends and holidays included.
One number for heat and air
AC, gas furnace, heat pump or rooftop unit, at home or at a business, anywhere across greater Houston. You do not need a different number for winter.
A live transfer, not a list
You are put through to a local company that already has a short summary of your problem, instead of being handed a list of names to work through yourself.
What the guides on this site are for
Most of this website is not about the line at all. It is about heating and cooling in the Houston area: why Gulf Coast humidity keeps drain lines and coils busy, what a long summer does to a compressor, how heat pumps and furnaces cope with the occasional hard freeze, what a fair repair quote looks like, and when replacing a system makes more sense than repairing it. There are pages for each service, for common problems such as an AC that runs without cooling or leaks water, and for towns across Harris, Fort Bend, Montgomery, Brazoria and Galveston counties.
The aim is simple. Whoever you end up hiring, through this line or not, you should know enough to describe the problem, ask good questions and recognize a straight answer.
How the pages are researched
Each page is written for its own topic and checked against public sources before it goes up: the National Weather Service office for Houston and Galveston for climate and storm history, the Texas Department of Licensing and Regulation for licensing rules, the City of Houston and suburban city websites for permits, the area's electric and gas utilities, and federal agencies for equipment and safety information. Every page lists its sources at the bottom with links, so you can read the original yourself. When a fact cannot be confirmed, it is left out.
The site follows a few fixed rules. It does not publish prices as if they were the line's prices; cost guides cite published ranges and say that real quotes vary. It does not name or rank HVAC companies. It does not give instructions for refrigerant, electrical or gas work, which belong to a licensed technician; it only describes safe checks such as the thermostat, the air filter and a single breaker reset.
Who the line is for
Homeowners and renters with a system that has stopped working or is about to, people shopping for a replacement who want to talk to a local company, landlords and property managers, and small businesses with rooftop or split systems. If you already have a company you trust, call them. The line is for when you do not, or when they cannot be reached.
Start with the services overview, read how the call works, or browse the service areas. Questions not covered here may be answered on the FAQ page.
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.
About this line: Houston Air & Heating is a free phone line, not an HVAC contractor. It answers your call and connects you with an independent local heating and air conditioning company, which inspects, quotes and does the work, and which you pay directly. Companies may pay a referral fee. You never pay the line. Read how the line works.
