Another hot weekend, another AC failure after working with Controlled Systems. Now $9-10K in and this has to be the 4th or 5th time the AC has failed. Every time they come out, it's another $1-2K. The problem never gets fixed. Last time they left after "fixing" the AC they let me know that the heat would now not be working. What?! Now it's scorching hot and nothing works. I will finally write this off to a terrible referral and move on. They also have no website, Yelp so....what does that tell you?

I used Controlled Systems for installation of our AC in 2017. Within a week of the install, there was a leak in the garage since the vent for condensation opened into our garage and the installers didn't pay attention to it. The company came and installed a makeshift pipe that empties into our garden from the garage, but we have another leak now, and I called them up and their response oh you didn't hire us for servicing. Will not recommend them ever. Services: A/C system dismantlement, Installation

Controlled Systems installed our heating system 10 years ago, added AC 6 years ago, and have kept both running in good condition the entire time. Vince was insightful and persistent about analyzing and repair a couple of intermittent issues. (Intermittent problems are the hardest to fix, whether HVAC, automotive, or computers. Services: HVAC system repair, HVAC system maintenance, Heating system installation, Install thermostat, Install AC

Controlled Systems is the ONLY provider you should call for HVAC service. The team is highly responsive and considerate. The management team led by Mike and Dawn was invaluable this winter. My tenants heating went out 3 days before Christmas and the Controlled Systems' team worked on Christmas eve to get my repairs in motion. Controlled Systems provided the most competitive pricing quote and was the most knowledgeable about our antiquated systems - AND how to cost effectively replace and repair my HVAC. In addition, the team takes extra precaution to be safe and sanitary which is extremely important during COVID times and vital for my tenants that have a new baby at home. Service: HVAC system maintenance
