HVAC Maintenance
Regular HVAC maintenance prevents breakdowns, extends system lifespan, and improves energy efficiency. Our technicians perform comprehensive safety checks, precision tune-ups, and priority service for plan members. Clients receive discounted repair rates and year-round reliability, with benefits exceeding the cost of standalone service calls.
Residential Plumbing
We handle emergency and routine plumbing services including pipe bursts, water heater repairs, drain clearing, and fixture installations. Our team provides upfront estimates, uses top-of-the-line equipment, and guarantees honest service with no hidden fees for Indianapolis homeowners.
Ductless Systems
Ductless mini-split systems offer zoned temperature control for homes without traditional ductwork. Ideal for room additions, garages, and isolated spaces, these energy-efficient systems feature quiet operation, flexible installation, and eco-friendly technology with wall-mounted indoor units and outdoor compressors.

Our indoor air quality solutions address allergens, mold, and pollutants through air purifiers, UV lights, and high-efficiency HVAC systems. Soldamist treatments eliminate bacteria and viruses, while programmable thermostats automate cleaner air management for healthier home environments.

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. Services: Heating system installation, AC installation

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 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 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.

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.

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 won't find that from most folks anymore. Planning on using them when I replace my next HVAC units.
