Boiler Service Near Denver CO

Excellent customer service! Both times they have come out they went above and beyond, doing little things that weren’t even part of the job. Highly recommend!

These good folks absolutely rock. Moved in to a new (to me) home, and with the bitter cold, the furnace went bonkers. They came out on NO notice, fixed it, cleaned it, adjusted everything and gave me some great maintenance advice. Chuck and Vincent were the solid service techs and the home office folks are super friendly, reassuring, and PROFESSIONAL. Fair pricing, too.

The advice they give and the work they do top-notch very very happy with the results the gentleman that came over and did the job was quick and very And he saved me quite a bit of money.

Exceptional service. Isidoro was punctual, had great communication before and during the service visit, and managed to fix my heating system within hours after I made an appointment. When I ran into another HVAC problem after business hours, he offered to return to my house in the evening and fixed the issue quickly. I highly recommend Controlling Systems to anyone in the Denver area.

I choose Controlling Systems to replace my old furnace with a heat pump and to add in air conditioning, which I did not have in my 100 year old house. Chris came by to give me details on the system they would install and to provide a very competitive estimate. He was available by phone to answer a few more questions that I had before I committed. The install took a day and a half and after a last minute decision, they also installed a whole-house humidifier. After the install, I had some issues with noises from the unit placed outside and the humidifier itself. Rudy came by and fixed these issues explaining what he did to damper the noises. He was very professional and also answered all my questions. I will definitely recommend Controlling Systems to anyone wishing to have a heat pump installed. I am now sitting very comfortably in my house, which has light humidity - perfect on a cold, dry Colorado winter day. The system is very quiet and I couldn't be happier with the result.
