"The service techs did a great job at taking their time looking over the HVAC and duct work. They were able to to resolve the problem by making some changes to the duct work and adding some different vents into the rooms (at an additional cost, but still affordable). 5 months later and the rooms are much better. We'd hire them again in a heart beat."

"Mid Tenn Home Solutions installed a 16 gallon per minute tankless hot water heater in replacement of two, decade old hot water heaters. After receiving several bids for this project, we selected Mid Tenn Home Solutions based on their five star ratings, project cost, professionalism, promptness and willingness to start our project whenever it was most convenient for our schedules. In less than 6 hours, they removed two rusting, leaking water heaters from our attic replacing them with one of the best tankless water heater system on the market. Their extensive, professional knowledge ensured us of a job well-done while enjoying the savings of our project budget. Finally, their company standards were only exceeded by the integrity and knowledge of Rocky and Stephen. Gentlemen, thank you for making what seemed to be an overwhelming, daunting task into a one day installation success story! 5 STAR perfection!!"

"This is the 2nd house I have had Robert install an entire AC/Heater Unit in. This last unit was a 5 ton that lasted me almost 18 years - When talking w/ Robert he wanted to ensure that the size of the existing unit was accurate prior to replacement. He came over in his off time just to double check the ceiling heights and sq. footage and confirmed that we were good to go. I appreciated that level of detail versus other companies that would just "punch in an order" and worry about it later. He will not try and sell you on things you dont want or need and was great to work with to try and save me a few bucks. I remember the first house he installed an AC/Heating unit in, he said "I live in this town and will definitely see my customers in the same grocery store and restaurants and dont want people to have anything other than a positive experience doing business with me". That always stuck with me and I am happy to give him the business."
