Andres came to replace a small part that was preventing us from getting hot water quickly. Response time was very quick, he was very professional calling before he arrived and arriving at the beginning of the stated window. He kept our house clean and made sure that everything was satisfactory prior to leaving. Overall there is nothing that could have been handled better from start to finish

Chris was outstanding throughout the mini split estimate and installation process. He was thorough, extremely knowledgeable, and took the time to properly size each room for the appropriate system. He clearly explained the difference between the available models and was very helpful in making sure we received all rebates and incentives available. We really appreciated his professionalism and attention to detail. The install was completed quicker than we expected. The technicians were again quite knowledgeable, thorough, and completed the work in a professional manner. We are very happy with Controlling Systems and would recommend them to anyone wanting a job very well done!

Controlling Systems just finished the installation of a new Mitsubishi Heat Pump system in my home. The process from inspection, quote and installation went smother than the last few remodel projects we have undertaken.

All of their employees were extremely courteous, knowledgeable, and very professional in the completion of the project. I would absolutely hire them again and recommend them for your next project.

We recently had a steam humidifier and UV air scrubber installed, and we couldn’t be happier with the experience from start to finish. The team is professional, knowledgeable, and respectful of our home. They took the time to explain how both systems work, answered all of our questions and made sure everything was installed cleanly and efficiently. We’ve already noticed a big improvement in our indoor air quality - the humidity levels feel much more comfortable and the air feels fresher overall. The installation was seamless and they left the work area spotless. Highly recommend this company to anyone looking to improve their homes comfort and air quality. Five stars all the way.

We have a MiniSplit heat pump system that caused us nothing but trouble in the 2 years we have had it. The original installer was of no help in getting the problem resolved. I tried 3 other HVAC companies in an effort to solve the problems, but they could not provide definitive solutions. In desperation, I called Controlling Systems. Their first technician knew we had problems he could not solve so he escalated the problem to their most senior technician. After a thorough analysis he found several problems including some that were not at all obvious. He mapped out a repair plan, gave me a detailed estimate of the cost and I approved the work. They were able to correct the botched installation over a 2-day period and now the system works perfectly. I highly recommend Controlling Systems and they now have a new loyal customer.

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!

I've been a customer for many years, and have always had excellent repair service for my old HVAC system. When it was time to replace it, I knew I could trust Controlling Systems with the job. Rory and Rudy expertly assessed what we would need and made sure that when Elijah and Brandon came to install the new system, it went smoothly. Everything was explained thoroughly and they made sure that all of our questions were answered. I look forward to many more years of working with this company.

Our church used Controlling Systems to install air conditioning. We talked to several companies. Controlling Systems wasn’t the cheapest but they were far and away the most professional. Elijah and Brandon were very reliable and expert technicians and the service was excellent. They answered our questions, came up with workable, economical solutions when they encountered problems and returned calls promptly. We feel that everyone went above and beyond to make the project successful. We’re very happy.
