Praise for Controlling Systems

“Great service, fair price, friendly techs…”

Very professional and polite. Did a great job.

Thank you for stopping by to replace the thermostat. I really like the touch screen. So easy to use. So far I am very pleased with the installation. Controlling Systems Inc. did a great job for me. Thanks to all the crew. Lou put out a bunch of effort.”

I would be more than happy to act as a referral at any time! I’ve had 3 other companies out and they don’t come anywhere close to yours!

I called Controlling Systems and I was assisted immediately. I talked to `Dave Bell and made an appointment for a house inspection and estimate. Dave came over , checked our house made some measurements, We discussed our options and he took the time to explain the differences . He left us with some brochures and a proposal to consider, he also recommened that I checkout the Carrier Web site. I read and learned. We made a deal over the phone and the system was installed by a extremely nice,clean, professional crew.

When we got home from work one afternoon, it was 64 degrees in the house, and we noticed the furnace was blowing cold air. We called Contorolling Systems at 4:30. Greg arrived about an hour later, and had the problem fixed within 30 minutes (he had the part right in the truck). The part that ignites had just worn out. We really appreciated the all-inclusive pricing (rather than parts and labor seperately) and the fact that he taught my husband how to do some basic cleaning to prevent additional problems down the road. We really appreciated the prompt service, knowledgable and friendly technician and were impressed with the service overall.

When the furnace went out on one of my rentals my “previous” contractor gave me an astronomical price for a replacement. I’ve dealt with this company for over 10 years. When I mentioned my problem to a friend he was quick to recommend your company. He’s referred a couple other friends to you as well. Your bid was much lower than the other one for the same furnace and your crew only took half a day to install the new one-two days sooner than the other guys. Seeing as how I was paying for the tenant’s substitute housing this was a real savings for me. Grant & Kevin are excellent technicians: leaving no mess and going over the new furnace with me. My entire experience with Controlling Systems has been a very positive one. Thanks for being so Customer Friendly.
