Great service and response! They came in to install a new unit for the upstairs. Not only were…read morethese guys professional, they were respectful and gave helpful tips on best practice maintenance! I was impressed with their lead guy Larry and the way he ran his small crew. They cleaned up after themselves and made sure we knew what to expect every step of the way. Just yesterday, their work was final inspected and passed with no issues. I'd recommend Mainstream to anyone who needs HVAC work done!! And ask for Larry! He is the bomb!

Their employees lack the training, skills, and company support to do their jobs. My system was recently completed and this morning it failed. The reason is it failed was it was not installed correctly. The owner will come on here and try and blame me for all the issues and you're free to figure out who's lying and who's telling the truth? And if you want to talk to me or see the horrific job they did please feel free to contact me. This company did a horrible job and has no clue what customer service means or customer satisfaction. Looks very much like they're going out of business so please do your diligence before signing a contract with Mainstream. Darryl Pater (owner of Mainstream) will respond to this and tell you this was all my fault. Believe who you will but his word is worthless and his moral compass seems broken. Frank Stewart is the only employee he has that is a man of his word and actually cares about the customer. I support small businesses wholeheartedly but this guy doesn't deserve to be in business any longer

Rod - the technician, was on time, professional, and he got straight to work. Even explained what he was doing and taught me about my specific unit. After he fixed the issue, he did more diagnostics just to make sure. There were no surprises when the bill came due. After getting gouged by some of the bigger companies in Mid TN I was very happy that they didn't try to take advantage. Will be using them again.

They did not ensure the drainage pan was in place so water damaged 2 floors, including flooding through the kitchen ceiling. No other person had access to this unit for this service or prior services. The owner acknowledged the damage and what caused it. He called and told me they would not service the house any longer and offered no compensation. They did not even offer a free service period. Nothing. The damage is in the thousands $$. The owners name is Cliff Haskins.

Bingo! Found it! The name of his company says it all! Honest? Yes. Explained things to me in a way I could understand since I have no knowledge about HVAC units. Told me options and explained his thought process behind it. My HVAC needed Freon. And it got what it needed. And now it is no longer in the 90° range inside the house. Another big perk is that he is a local from Mount Juliet. I really do like to support local businesses and this is one that I would use again if I needed. 17/10 recommend!

Dave was one of the first people to respond to my request, and came out to investigate what the issue was. I appreciated that Dave talked me through what he was doing and how the AC unit & thermostat worked so I understood some basics of why things were not functioning correctly.

He also helped us install new thermostats and everything is running smoothly now! Dave is efficient with the work and an excellent communicator. We highly recommend his HVAC services!

Nothing fancy; just clean and check the unit for the summer. That's when they came to my house and told me that my unit had over five problems, including leaking refrigerant, bad capacitors, electrical work, etc. Funny enough, their first quote was for 8k, which was to "fix these terrible problems." However, they gave me another crazier solution, to get a brand new unit, which was only 2 tons for a small house for 11k. Kid, you not. I went and got a second opinion, and as I suspected, my HVAC connections weren't the prettiest, but had no problems. The other HVAC professional also found out that they only cleaned a portion of the unit, so he installed a new disconnect, re-did my drain line, sealed my flashing, and rewashed my unit for $600 bucks. Do it at your own risk. I have never seen something like this, not even when I used to live in NY they tried to upcharge me like that.
