Jennings Heating & Air Conditioning

Jennings Heating & Air Conditioning runs as a family-owned HVAC outfit based right in Hopkins County, Texas, with Sulphur Springs as home base. Ernst Jennings stays hands-on as the owner-operator and has kept the business going strong for more than ten years across East Texas, including Cooper and the surrounding towns. They hold the state HVAC license and stay open seven days a week from eight in the morning until seven at night. Homeowners call them for seasonal tune-ups and the kind of sudden breakdowns that hit during the worst heat or cold. Ernst answers messages himself and often rolls out with the crew instead of sending strangers.

The crew handles full AC replacements, same-day repairs on units that quit overnight, and regular maintenance contracts that keep systems running through Texas summers. Ashley Alexander reached Ernst after hours and got a next-day visit where he fixed one unit on the spot and flagged the older one for replacement. John Weber had them install two complete house units and keeps them on for ongoing service because Ernst shows up quick and knows the equipment. Tricia Griffin called at seven in the morning with no cooling and had a tech at the door by eight-thirty. Alissa Morton has renewed her three-year plan after six years because the visits stay on schedule and the work holds up without surprises.

Customers keep giving top marks because the work quality stays high, response times beat what bigger outfits promise, prices stay fair with no hidden fees, and communication comes straight from Ernst without runaround. Reviewers mention the honesty on older equipment decisions and the follow-up after installs that feels like the way things used to get done. That steady reliability across hundreds of jobs in Hopkins County adds up to the kind of reputation that does not need extra talk. DIRT Score 5.0 from 170 reviews on Finds.

“An absolute lifesaver! I contacted Ernest after business hours, and he responded promptly. He showed up the very next day to inspect our two AC units. He was able to fix one issue right on the spot and correctly identified that our second, older unit needed to be replaced. ​He ordered the replacement immediately and had our entire system back up and running in less than 48 hours. His crew was professional, polite, and efficient. They did a fantastic job from start to finish. We will definitely be using them again in the future. Thanks for all your help—it was a pleasure doing business with you! If you need a reliable fast service call Ernest and his crew. He will do his best to get you fixed up and running. A 5 star review just isn't enough.”

“We’ve trusted Jennings Heat & Air since we bought our home six years ago, and there’s a reason we just renewed our three-year service plan with them. Mr. Jennings runs a business built on reliability, honesty, and true professionalism. They’re always on time, always efficient, and I love that they send before-and-after photos so we can see exactly what was done during each visit. It’s rare to find a company that cares this much about quality and customer service. If you’re looking for a local HVAC team you can count on year after year, Jennings Heat & Air is it. We are proud to support their business!”

“Awesome experience! Called at 7am with AC issues and a tech was at my house by 8:30am. Fast, friendly, trustworthy tech! I will be calling for any future AC/Heat needs! Thanks Jennings!!!”

“Ernst responded to an urgent request on a weekend and promptly provided outstanding service. He is a professional with outstanding expertise and efficiency with very fair pricing. I signed up for his seasonal maintenance program based on that experience. I look forward to the security that Ernst Jennings Heat and AC will provide.”
