About Us

Serving You Since 1975

Established in 1975, Glenn Aire Company has been serving Hood and the surrounding counties for over 50 years. 2025 marks our 50th year in business. In that time we have mastered expertise in a variety of system types including air conditioning, heat pumps systems, geothermal heat pump systems, light commercial systems, home automation, and air filtration. Our slogan is “Exceeding Expectations in Comfort and Efficiency,” and the primary purpose of the company is to design, engineer, install, service, and maintain residential and light commercial air conditioning systems.

While we are a local Trane Comfort Specialist dealer, we service all brands of heating and air conditioning equipment and will give you free estimates on system change outs without any high pressure sales tactics.

Glenn Aire Company owner, Jeff McKenzie, has been in the air conditioning business for over 32 years; his experience spans all aspects of the residential and commercial HVAC field. Previous to taking over Glenn Aire Company, Jeff worked for the Trane Company for 10 years, and for the last 6 years was a Territory Manager for the southern area of Texas Trane out of Dallas/Ft. Worth.

 

Jeff’s son, Matt McKenzie, came to Glenn Aire Company in March 2008. Before joining his father, Matt attended Austin College in Sherman, TX, worked for Advent Air Conditioning Company in Lewisville, TX, and was in the United States Air Force. Bringing Matt on board demonstrates our commitment to customers and the community that we hope to be here for many years.

Our Roots

Glenn Aire Company was established in 1975 as a sole proprietorship by Glenn D. Cornelius in Granbury, Hood County, Texas. The business has operated uninterrupted under the same, original name. In 2005, after 30 years, Glenn decided to retire and turned over the helm to Jeff McKenzie.

While the primary purpose of this company is to design, engineer, install, service, and maintain residential and light commercial air conditioning systems, we have expertise in a variety of system types including air conditioning systems, heat pump systems, geothermal heat pump systems, light commercial systems, home automation, and air filtration. Our technicians are trained, fully licensed and we hire NATE (North American Technical Excellence) certified technicians to insure your system will be comfortable and energy efficient when installed, repaired, or replaced. We rely heavily on our many years of experience—having installed over 10,000 systems—and continue to seek training and understanding in the latest technology.

Best of Hood County

Glenn Aire Company has received many national awards and is recognized as an Independent Trane Comfort Specialist dealer. On a local level, we were named Best of Hood County Runner Up in Air Conditioning and Heating in 2012, 2013 and 2014. We pride ourselves in our customer relationships and customer service. We have never had any consumer litigation filed against us, nor have we ever operated under protection of bankruptcy laws.

We maintain not only all required licenses (TACLA24048E) and certifications to operate in this industry, but we go a step further by hiring NATE (North American Technical Excellence) certified technicians. We are fully insured through The Hartford Insurance Company.

Glenn Aire Company thanks you for the opportunity to come out and give you a free in-home proposal or to service your equipment. We look forward to working with you now and in the future.
