Why Choose Texas Air Mechanical as Your Boiler & HVAC Installers

We know there are many companies in the DFW Metro area that are boiler and HVAC installers, but few have the expertise of Texas Air Mechanical. All our technicians are licensed and factory-certified. Before we provide you with a quote for a new unit, we’ll evaluate your home or facility to determine the right type and size system. We’ll then provide you several options based on your preference, needs and budget.

You’ll find that when you choose us as your HVAC installers, all work is done in accordance with not only the manufacturer’s instructions, but also local and state code. We want to ensure that your new system is properly installed so you benefit from the full factory warranty in addition to our installation guarantee.

Because we’re locally owned and operated, we truly care about our reputation. Texas Air Mechanical is A+ rated by the Better Business Bureau, and we also have countless five-star reviews from our residential and commercial customers.
