In this world where it's so difficult to get even the most basic service, what a fantastic surprise to get same day service and have my AC back up and running immediately. My second experience with this company and I 100% recommend them!

Miller installed our system 3 years ago and we've used their preventative maintenance program. Fantastic folks and service. Scot came out today for the annual PM check. Great representative for the company. Punctual, courteous, and knowledgeable. Thorough inspection of the 2 systems and cleaned each system thoroughly. Great folks and highly recommend them to anyone

I would like to take a moment out to recognize a great company in Port St. Joe, Miller Heating and Air. From the moment I called, I was met with an upbeat young lady that answered my questions, gave me a quote, since I was not an emergency she scheduled me one week out and made my call the first. Everything went as described and I had the privilege o Sr. Tech Scott and his outstanding young asst. Brett.

Both were extremely pleasant, helpful and hard working. They answered all of my questions and finished in a timely manner. Well done Miller Heating and Air.a family business you can trust in.

These days it's so hard to get what you pay for and what you expect. Miller Heating and Air is one in a million. Fast courteous service at a price you can afford. Not only did they show up quickly and fix the problem but he was so nice and even removed his shoes when he came in the house. Thank you! It's so nice to know people like you.
