Before online reviews and digital service calls shaped the heating, ventilation and air conditioning industry, North Texas businesses were built the old-fashioned way: through relationships, reputation and word of mouth.
That legacy remains at the center of Coventry & Gattis Air Conditioning, a Grapevine-based residential HVAC company with roots over five decades old.
The history of Coventry & Gattis AC
The story begins in 1971, when the Gattis family founded Gattis Heating and Air Conditioning in Grapevine. In 1978, Paul Coventry entered the industry, learning the trade and gaining experience to establish his own company, Coventry Air.
For decades, both businesses became familiar names in the community. Then, after Tommy Gattis passed away in 1999, the companies eventually came together, officially forming Coventry & Gattis in 2005.
Today, the company is owned by brothers Chris and Nick Wellborn from Grapevine, who took over in 2017 after meeting Paul Coventry.
Built on trust
What drew the Wellborn brothers in was not just the business but its values.
“Paul was particular about who he wanted to sell the business to,” Chris said. “The chemistry and values had to align, and that was the case with us.”
Those values still shape the company’s identity today.
The Wellborn brothers came from management backgrounds outside the HVAC industry—Chris managed a Daltile branch, while Nick managed a Sherwin-Williams store. They said the transition into home services felt natural because the business centered on something they believed mattered: trust.
A no-pressure approach
That idea repeatedly surfaces in the company’s approach to residential air conditioning service, repair and replacement in Grapevine and surrounding North Texas communities.
Technicians are trained to prioritize homeowners’ concerns over upselling.
In the HVAC industry, homeowners face long lists of problems or expensive recommendations. Coventry & Gattis emphasizes communication and transparency, walking customers through issues step by step and asking permission before proceeding.
“Homeowners are always in control,” Chris said.
That approach has become important in an industry where some customers enter service calls skeptical or worried about being pressured into costly repairs.
Instead of overwhelming customers, technicians focus on explaining what matters most, showing homeowners what they see, and allowing them to make informed decisions at their pace.
What they offer
Coventry & Gattis exclusively serves residential customers and offers HVAC services for North Texas homeowners, including:
- Air conditioning repair and replacement
- Heating system service and installation
- Seasonal HVAC tune-ups
- Indoor air quality solutions
- Preventive maintenance services
The company’s visible entry point for new customers is its $99 HVAC tune-up offer, which includes a future service credit for homeowners who schedule before the promotional deadline.
The standard they maintain
Beyond promotions or equipment, the company’s reputation is built on consistency—showing up, communicating clearly and treating customers fairly.
The Wellborn brothers continue to hold regular internal meetings focused on the company’s core values and customer experience. Much of that philosophy traces back to the Gattis family and Paul Coventry, whom they describe as guided by integrity and doing the right thing.
Coventry & Gattis reflects Grapevine’s evolution: a longtime local business that has changed ownership and grown while holding onto its community roots.
