The Lennox website indicates this company is one of its dealers. So I thought that I could purchase a pressure switch for my Lennox furnace. I went their office and gave them the model of my Lennox furnace and the part I wanted, but was told that they don't sell parts over the counter and need to a $ 99 diagnosis of my furnace before selling the pressure switch to me. This is what a dealer does? Very disappointing!

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 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 AC 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

Weve used Control Tech for years and have never been disappointed. Theyve always gone out of their way to do things right and make sure we are satisfied. They are also very professional and reasonably priced. This service was- as always- professional, helpful, and a good experience.

Been using Control Tech for years. They maintained my previous system so well. That I hired them to install the last one. They stand behind their products. Family company and local. They have told me when I needed to do things and when they could wait. You wont find that from most folks anymore. Planning on using them when I replace my next HVAC units.

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.
