Marissa Hols

“We’ve used Hern three times now and are so happy with the service (an annual service, maintenance, and an upgrade to our system)! They were professional and have the best customer service! The prices are competitive and Scott took the time to explain how to make little tweaks with our unit to help it run more efficiently! Andrea in the office is so helpful and we will be customers for as long as we are in Florida!”

Jim McNaull

“My old AC unit failed mid-summer and the pro's from Hern Heating and Air were able to help quickly with a great new RUUD heat pump and air handler that are far more efficient. Thier tech Scott, did a fantastic job and left everything clean and working perfectly. He even followed up to make sure that everything was going well a week after. Great service and a fair price. Our home has never been so comfortable or our electric bill so low! Sincere thanks to Scott and Hern Heating and Air.”

Melinda Coffman

“Excellent customer service and outstanding craftsmanship. Prompt and courteous with attention to every detail. No areas of improvement which is absolutely refreshing in today's society. I would absolutely recommend Hern Construction & Heating and Air without reservation. The quality they provide is only surpassed by their customer service.”

Amanda Beamer

“We recently discovered my daughter is severely allergic to dust and mold. The staff at Hern HVAC showed genuine concern for her health during and after installation of our new unit and duct work. I would recommend them over and over again!!! They were punctual and the job took exactly the length of time they quoted us. They were meticulous about cleaning up and removal.”
