Customer Testimonials

Dear Alan,
Mrs. Walker Testimonial
Thank You So Much for making the purchase of my new Lennox heat and air system, so easy. It was the best experience, of making a major investment, I have ever had. Your office ladies are wonderful. Always pleasant and you can hear the smile in their voices when they speak with you. What nice phone people they are. Now, the installers... Wow! They worked so hard on the installation of the units. The first day, they never even left for lunch. The second day, I bought and made sure they ate. They answered all my questions and explained everything, so even I could understand it. They were so knowledgeable and it was a great feeling having them in my home.

The only one left; is you Alan. What a gentleman you are. You were so wonderful to deal with. It was so nice of you to stop by and make me feel like I was your only customer and special. I now know why my son thinks so much of you. Alan, you and your staff are fabulous! Thank You for all you did.

Most Sincerely,

Betty Sue Walker, Indianapolis, IN

Hi Clay,
Mr. Dafforn testimonial Control Tech
Thanks for your message last week. The whole system is very nice, and it's all programmed for our wake/sleep times (since we work at home, we really don't need the leave/return settings).

Curtis and Brian did a REALLY nice job with the install, explaining things, and making sure we were happy and informed the whole time. I hope the survey that we returned reflects that. We'd recommend Control Tech to anyone.

Thanks again. Hope to talk to you soon. 

 -Erik Dafforn, Carmel, IN

"Control Tech services our heating and air conditioning units. We have a contract with them to come out twice a year for check ups. We have two systems that they service both of.  Their technician, David, that comes out is just great. He is very professional and friendly.
I babysit for my grandson and while he was sleeping, David worked very quietly around him which I appreciated. I will continue to use them."  - Steve C., Indianapolis, IN

"Control Tech worked on my furnace and A/C in the Spring and Fall. No complaints, they have been exceptional. They are very high quality service." Barbara W. Carmel, Indiana

"Control Tech installed a humidifier for me.  I feel that they were creative with the installation because I don't have a drain. They did good work and I recommended them to a neighbor."
A Hewlett, Brownsburg, IN

"Control Tech has been taking care of my HVAC for, maybe 30 years, at my west side house and, now, my NE side condo. Most of the time its been servicing our maintenance contract, but they have also done more major repairs of heater and air conditioning unit. Over the years I've dealt with many different techs and without exception would say they were knowledgeable and helpful. I got a kick out of this most recent one who tried his best to find my cost savings, discounts, coupons, etc. Always polite. Scrupulous about wearing boot coverings when entering the house." - R. Dickinson, Indianapolis, IN

"These guys are great - every time! I purchased the Fall/Spring package for my new home. The Control Tech technician wore his blue booties in the house, was right on time and in no rush to leave until all questions were answered. I asked him to explain the system to me (especially the humidifier, the filters). He told me how to clean the filters and how frequently, explained how the humidifier worked and showed me how to use the dial upstairs. He also provided hints for improving heat levels upstairs in my old home. He cleaned the filters thoroughly and explained the duct work in my basement, even showing me how to open and shut the flow between rooms using little levers on the duct work. He told me someone purchased an expensive and efficient heating system years ago (the one I currently have) and that the original duct work was impressive in its quality. He stayed over an hour on task. At my old home (currently a rental unit they also serviced this Fall), I've called Control Tech in the middle of the night on two occasions when the heat has gone out and they've shown up immediately. I'm always impressed with their price and quality! I've recommended them since Alan first opened his business a long time ago." - A Hudson Zionsville, IN

"I received the Control Tech fall furnace maintenance for a one year maintenance deal I bought. They changed filters and checked all working parts in furnace. Also changed humidifier filter. The Control Tech repairman actually called day before appointment and was in area and asked to come over which was fine since I was home. He was very polite and wore shoe coverings as he has to go in and out. He did all the general fall furnace maintenance and even spoke to my husband on the phone, as he has some questions. As he was leaving he recommended that we leave the blower in the "on " position all of the time as it would heat and cool our home more effectively. We have lived here for 5 years and have had an ongoing problem keeping the upper and lower floors and appropriate temperature in our 3 story home. This was good to know!" Rich T, Zionsville, IN

"Control Tech came to our house and installed a new air conditioning unit.
They were great and we were pleased with them. They were professional and they got the
job done in a timely manner. They went above and beyond. I would recommend them."
Gary G Zionsville, IN

"Control Tech added venting & exhaust fan vent in basement, added natural gas line for outside patio. Crew did a great job. Jim came and gave an estimate. I added some items after estimate, and felt the additional work was reasonably priced. Also signed up for maintenance plan maintenance was performed on time and efficiently. Will hire again." Stewart I, Westfield IN

"Control Tech came out for their three times Scheduled Maintenance Precision Tune-Up and
Safety Check. I would definitely recommend their Scheduled Maintenance Agreements. I've had to call them before when my furnace wasn't working in the wintertime. They'd give me advice over the phone. They're so professional, and always remove their shoes. I cannot say
enough about them. They are always great. Ryan was the service tech out here the last
time." LORI B, Carmel Indiana

"Control Tech came and did a cleaning and check-up in Spring and Fall. They fixed a heating and cooling problem as well. They were very professional. Their office people were accommodating and they call you back. They really seemed to know what they were doing. It was a pleasant experience." Cindy B,  Indianapolis, IN

"I just wanted to write a note to thank Control Tech for providing such excellent service. I just moved into a 30 year old home and have been having trouble with the furnace. I've called for service three times in less than 3 months and your service technicians and phone operators have been so wonderful. I so appreciate how helpful and knowledgeable everyone has been. I always dread having to have service because I feel like I'm going to be taken advantage of, but your people have never made me feel that way. It isn't often when I feel like businesses are on my side. I appreciate the professionalism that I have been shown and I will absolutely recommend Control Tech to everyone!" - Jenny G. - Zionsville, IN

"Our five ton air conditioner was replaced by Control Tech with a new unit. The work was performed in a timely manner and was very professional. I would recommend Control Tech.  In addition, I recieved a competing quote which was $2,400 higher." - David G. - Carmel, IN

"Overall, it was a good investment and a great experience have Jeremy and Joshua replace our heat pump and all the components. What we will remember most are the two representatives that performed such an excellent job and showed such maturity and professional behavior for such young men. Both my wife and I have extensive supervisory and managerial experience and were very impressed by their work ethics. The two young men were very competent in what they had to do; displayed very good team work and performed high quality work. My wife and I appreciate their friendly and polite behavior which left a very favorable impression. We would recommend Control Tech very highly." - Humberto A. - Zionsville, IN

"Not only was our service from Control Tech great when we invested in central air and replaced our furnace, but our gas bills have decreased $44.00 per month, saving us $528.00 per year. Over the next few years, the units will have paid for themselves. We are extremely pleased with the increase in efficiency that we are getting from our 100 year old home and would highly recommend Control Tech to anyone for their heating and cooling needs."
- Mark & Courtney Z. - Indianapolis, IN

"After using two or three other heating and air conditioning companies over the years and getting average or poor service - I am relieved to now have Control Tech taking care of my aging heat pump.  They are fairly priced, on time, polite, and the work is always expertly done the first time.  I am also a Maintenance Agreement customer and find this to be the best way to go." - Dave P. - Carmel IN
