“Controlling Systems installed a tankless water heater in our home a year ago. We have loved this unit but we started having a few issues. Bailey came over to diagnose the problem. He was able to identify that it was due to a manufacturer’s defect. He worked with the manufacturer and was able to get the part overnighted. He returned to our home the next day and fixed the issue. Bailey was friendly, respectful, professional and skilled in his craft. He also made sure to protect our floors as he came in and out of the house and cleaned up any mess made during the repair. I would highly recommend Controlling Systems for all your HVAC needs!”

“We could not be happier with Controlling Systems and our heat pump repair process. They were incredibly responsive, informative, easy to work with, one of the best quotes we received, and true to their word. Controlling Systems will be our go-to for any other related services that we need.”

“I have used this company across multiple residents. I have used them for install of AC units and swamp coolers. I have also used them to maintain the units I purchased. They have always been customer focused, friendly, and cost competitive.”

“An HVAC company that does what they promise, in reasonable time, for market-reasonable cost? With pleasant humans throughout the process?? Unheard of. Until I hired Controlling Systems to replace my 14-year buggy radiant home heating and on-demand hot water system. Seven of the contractors who looked at my mess earned a spot on the spreadsheet comparing contenders. Some said stupid salesy-desperate things like, “ours is the only high-efficiency unit on the market,” and, “only ours is the top model.” Ich. Bailey’s deep knowledge and clear, straightforward communication earned my trust, and then he followed through! Over the years I’ve paid a LOT of HVAC guys to not fix the prior system, or clearly recommend actual replacement options, featuring the outcomes I could expect, especially concerning heating the cold spots in the house. What a breath of fresh (warm!) air: with Gus’ smiling assistance, Bailey expertly installed a new unit, which runs economically, quietly, and I can trust, reliably for many years to come. 10 stars!”

“Best service call I’ve ever received!! Showed up super fast, within an hour of me calling. Bailey was excellent, super professional, super polite and very knowledgeable and actually showed me how my furnace worked! Super helpful! He came in and actually fix the furnace quickly ! Very happy with your company and with Bailey and I guarantee I’ll be calling again with any other problems in the future. Highly recommend your company! Thank you so much!”

“Roman and John replaced a central a/c unit and water heater. Great experience from initial evaluation to estimate to install process. I rehired Controlling Systems after they did an extensive furnace/ductwork replacement project and installed a new central a/c system in my previous home. Their teams are courteous, efficient and very skilled. Five star service”
