Controlling Systems provides great service and friendly staff, highly recommend you schedule your maintenance and new installations through them! Anthony G attended us and was proffesional and knowledgeable!
My experience with controlling Systems was excellent. Jim and Elijah installed an AC unit and an attic furnace. They worked continuously for two days until completing the install. At all times they were cordial, thorough and kept me up to date with every component of the install. In addition they both spent time answering all of my questions during the install and after. Finally, I accepted proposals from several HVAC companies before choosing CS. I chose CS because their proposal was the most affordable considering everything included and also because they seemed the most knowledgeable.
I'm very happy I went with Controlling Systems for my major HVAC system overhaul! I upgraded to an electric heat pump hybrid heating/cooling system and an electric heat pump water heater. Chris was very knowledgable about all my different options, and worked with me to choose the best system for my house and my budget. He also got me all the relevant Excel rebates, saving me about $11,000 total. Elijah and his crew did a great job with the installation. Everything went smoothly and was completed much faster than I expected. I definitely recommend this company and would work with them again!
