HVAC maintenance

“Technician was early with a badge on his shirt identifying him as a technician with Controlling Systems. Polite, efficient, pleasant and knowledgeable! Advised on future HVAC maintenance. I highly recommend Controlling Systems and have used them for many years and will continue to do so!!

“When I called they got me an appt very soon and were extremely nice. Our technician was Aireus and he was fantastic. He explained things to me and was able to fix the problem same day! Highly recommended Controlling Systems!”

ALWAYS Polite, professional, friendly

The heat went out at my mothers house. I called the people who installed it initially. Then called Controlling Systems. The had a technician out and it was repaired before I got a call back from the first company. Service is ALWAYS Polite, professional, friendly (big plus in my book) and efficient. Just the way I like it.

Tomoko K.

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!

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!

Service was top-quality in every respect.

Scheduled maintenance on furnace. Technician was on time, very competent and went out of his way to explain everything he was doing. He made sure the service call was covered under our maintenance contract. Service was top-quality in every respect.

Chip B.

Showed up on time

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.

Kari K.

Professional, on time, great communication.

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. Shout out to Gus and Arius for all that they did to problem solve and fix the issue. Professional, on time, great communication. I would recommend! I know I will call them in he future!
