"Ruben was awesome. Installed an A/C unit and a new furnace in 1 day. Super nice and relatable. Did great work, even dealt with my dogs barking at him everytime he came inside, haha. Cannot recommend enough. Gave us a great deal and great service. Kept in contact and kept us informed. 10/10"

"We had the folks from Tuscan Electric complete a difficult project for us yesterday. They provided a competitive estimate, scheduling was easy, and they showed up on time, and added additional man-power as required to complete the project. We replaced a main entrance foyer light, a dining room light, a ceiling fan in our great room, and the replacement of 18 recessed lights in our walkout basement w/new LED lighting. The issue was that the entry and great room replacements were needed to be completed on current devices installed at a height of 25+ foot. They had to rent a 20 foot ladder, have 3 guys to help navigate the install, the span and weight of the ladder, and a multi lift and to complete the build in the clouds. They were a terrific team, who worked well and in unison. Much thanks to Domenic, Jake, and Jim. We highly recommend..."

"Tony did a great job replacing my broken 50 gallon self venting hot water heater. It is in a difficult space to maneuver getting the old one out and the new one in. He did a great job updating what needed to be done (in my old 1910 home so there is always something!) and I feel very confident in their work. Limelight is my go to place and am so glad I found them!"

"On this project, Matt came 24hours after my call to remove an exterior AC unit sitting on a retaining wall (suddenly re-scheduled to be rebuilt the next day). A few days later he returned to reinstall the AC unit. I’ve enjoyed working with Matt since February 2020 when he replaced a broken furnace during a bitter cold snap - now he is my prefered HVAC tech. Matt is personable, a great communicator and really knows his stuff (worked 12+ years in HVAC). I’m the type of customer who wants to know why something works or doesn’t and he answers in terms I can understand. I also appreciate the tips he offers on maintenance and caring for my system. "

"The repair was made.  Sean, the service tech was courteous and professional and obviously knew what he was doing. He replaced the circuit board which took less than 1/2 hour and for that I was charged $597.00. Thinking that the circuit board was pricey (Sean, the service tech indicated so), I thought the repair bill of $597 was reasonable.  Only after calling some stores (the next day) and finding out a circuit board cost $125 did I realize I got ripped off. Controlling Systems labor charge for 1/2 hour work amounted to $472. I called the owner/guy in charge to request a refund for part of the labor charge. (I really didn't expect to receive anything) Not only did this person(whose name I wished I remembered, I would state it here) not want to hear my complaint, he hung up on me because he knew he ripped me off. He was rude and didn't want to hear my complaint. He obviously didn't want to hear anything I had to say, only stating that I agreed to the repair charge beforehand. To that he's correct, I did agree to the charge but when I asked Sean what was the cost of the circuit board, he said  $250-300. Now I know parts are marked up when purchased through a company such as CS but I still believe this company took advantage of me. ( and probably hundreds of others out there). Controlling Systems did not provide parts cost, labor costs, etc in their estimate which they used to (I had used them 3 years ago, but I won't ever use them again) Future potential customers take heed: I WOULD ALWAYS REQUEST THE ESTIMATE REPAIR BILL BE BROKEN DOWN to parts cost, labor cost, etc. And if they tell you they can't provide that, that's a good sign you're being overcharged. <br /> Normally I am careful about negotiating and reading the fine print, etc. but this day I was distracted and the temperature was in the teens. I wanted the furnace fixed and I didn't have time to get estimates. Also if I hadn't  used Controlling Systems I would have been charged the $100 diagnostic(service) charge. Lastly, Sean intially quoted me $700. When I told him I was going to get other estimates, he lowered the estimate to $597. <br />"

"I highly recommend Tyler with Bison Mechanical for any furnace or HVAC needs. He provided exceptional, professional service with a same-day response that saved me over $1,000 compared to other estimates. Tyler is remarkably honest and efficient, making what is typically an intimidating process entirely seamless. He came highly recommended to me, and I will certainly be recommending him to everyone I know."
