From consultation to installation, the Control Tech team did an excellent job! During consultation, Matt Butler answered our questions and provided us with several opinions and options. He was very knowledgeable and professional. His communication was great and he was very responsive through phone and email. The installation team (Doug and Doug) showed up on time on the installation days. They did a great job of answering our questions and always kept us updated on their progress. They were professional and did a great job of preparing the area and cleaning up after they were finished. Their expertise in installation did not go unnoticed. The cost of the products/installation was reasonable and what we budgeted for. I would highly recommend Control Tech!

I feel like I do not share good reviews enough and am always quick to review when we receive bad service. I wanted to be sure to give the people at Control Tech a good review. Our heat went out back in February when I was about 3 days away from my due date with our first child. It was freezing cold outside and we needed heat stat. Control Tech was able to get us in the next day and got our heat running that night. Then when the heat wave came in June we found our A/C was not cooling properly, we had to go through the weekend with a hot house but they were able to come out the Monday I called to get it fixed for us. We now have a happy household and everyone is sleeping more comfortably including out almost 4 month old. So happy with our choice to have our 20 year old HVAC replaced by Control Tech and would HIGHLY RECOMMEND. Thank you!

I have used Control tech for all of my heating and A/C maintenance since moving to Zionsville, and have not been disappointed. When a new system was needed I chose them over other known companies and received amazing deals. Customer service has always been great and never an issue to get any needs attended to quickly. I have had great experiences with Jeremy on the sales team, and every tech has been courteous and professional when visiting for maintenance. I would recommend this company 100%

I have used Control Tech for a few years now. They are very responsive and professional. They affordably installed a new system at one home and have done checkups at the new home. Once they came out to do a scheduled check up for my unit and the technician discovered a gas leak from my water heater, then fixed it. I couldn't thank that tech enough. Great service. 10 out of 10. Would recommend.

Control Tech is an honest, professional company. They truly stand behind their product and services. Responsive and timely, I would not use any other company for my HVAC needs.

I used ControlTech back in 2015 to install a new furnace and A/C unit. Since then, I have been using their 3/year service program for the system. I find their technicians to be knowledgeable, professional, and on-time. I have had a few minor issues with the system and they have resolved during the regular service call. I also find their plan to be a good value for ensuring my system operates properly.
