Mainstream Heating & Cooling came out due to not getting heat on my unit. It was determined my gas was not connected. They recommended i call to get it turned on. They didnt charge me anything for the simple fix. Friendly, Dependable, Reasonable and good customer service are a few reasons to give them a try. The cherry on top is the knowledge of service. I would recommend giving them a call if your in need of service.

Very personable and eager for the business. They were able to get me in the next day for a tune up and helped me find Mr B's to clean our dryer vent. Will definitely use again!

I called yesterday with an emergency and I was a first-time customer. Not only were they able to fit me in and were there within 90 minutes of me calling, the technician was very professional, very thorough, telling me what the problem was and fixing it very quickly. The price was also very reasonable. This company will be my go-to company for my HVAC and I would recommend them to anyone!

I had Mainstream out to my house yesterday to finish something that they found was wrong when they were here this summer. Not only did they do a great job, but they also were very fair on the price. Matt did a great job as usual! Thanks, Matt!!

Mainstream has been servicing our Trane unit since we had it installed some 4 years back. I've given them a 5 star then and still rate them as a 5 star service. I am a club member which I recommend from its benefits it provides and I absolutely love David from their team. He is top notch and has been to my house several times over the years for maintenance or after hours emergency calls. You cant go wrong.

We had an emergency after hours and they showed up in the middle of the night, the lovely man who came even whispered because we had a baby sleeping. Fixed the problem quickly, had reasonable pricing, and scheduled maintenance for the following day. The following day two men came and were also super friendly, explained everything that they did, and did it all in a timely manner

In this day of hard-to-find-good-help, Mainstream Heating and Cooling Service is undoubtedly the top of the line. From scheduling to work completion the Mainstream Team was courteous, thorough and very efficient. Jeremy was on time and quickly assessed the problem and made several suitable recommendations to reroute my two HVAC unit condensation lines to another more appropriate side of my house. Job was quickly completed and clean up was thorough. Great service at a fair price from a true professional. I would highly recommend Mainstream Heating and Cooling to anyone who wants good results at a reasonable price...thanks!! Russ L

Our unit was 15 years old and showing its age. I had several companies come out and give me estimates for a replacement system and decided to go with Mainstream based on their prices, equipment, warranty, and the way the initial estimate process went. No hard selling, no telling me I needed this and that, and they didn't try to add on unnecessary extra work like re-doing some of the ducts etc.
The installers showed up on time (seems to be a rarity in Clarksville) and both were professional, competent, friendly, and very patient with me looking over their shoulders from time to time and asking questions.
They did a great job with the installation, cleaned up after themselves, and now we have a much quieter system and ice cold air blowing out of the vents.
Highly recommend this company!
Edit 9/04/20 - A few days ago I came home from work and our A/C was out. I called Mainstream and they immediately sent out a tech. Jeremy troubleshot the problem to a stuck valve on the coil; unfortunately they had to order the part but they put a rush on it and it was there the next day. Was I happy about not having A/C during this heat and humidity? No, but on the other hand, I can't say enough about their excellent & prompt customer service. I'm so happy I went with this company!
