ALWAYS Polite, professional, friendly
I would highly recommend this company.
Two installers were sent the day of installation. They were both courteous and professional! They arrived on time and immediately dismantled the old system and prepared the space for the new system! They were very efficient and worked well together as a team. Following the completion of their work, they ran the furnace and explained the functions of the thermostat in great detail!
I want to thank both Gemini and Roman for their attention to detail, answering our endless questions, and removing all remnants of their work! I would highly recommend this company and these two employees!
Very professional
Very professional! Have used Controlling Systems for the past few years for swamp cooler start up and shut down. This time the installed a Halo water system. So far very happy with the system and continue to use their team for future needs!
Recommend Controlling Systems
The two men that came out to install my AC/Furnace did an excellent job. They were on time, they were courteous, and always kept me in the loop as to what they were doing. Before leaving my home, they tested everything and made sure to walk me through how everything worked. I would highly recommend Controlling Systems to anyone in need of HVAC. Thank you!

Great Job! I have a hot water/boiler heat system that gave us a mind bending problem! Not always easy to fix residential repair people that know what they are doing.

From the moment I called to set up my appointment to the in-person visit to winterize my swamp cooler, I received outstanding service. The technicians showed up on time, were totally respectful of our home, answered all my questions, and were very friendly. I thought the service was priced very fairly and that I got a great value.
