Controlling Systems Furnace, Air Conditioning, Electrical, Solar Service and Repair - Denver, Colorado

Sharon A.

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.

I wasn’t sure if I was going to leave a review or not, but I will be doing business with Controlling Systems again in the future, so I’m hoping this positive review helps keep them around. I’ve had HVAC and plumbing work done in the past through other companies and decided to try a new vendor for my most recent project: a heat pump water heater install and removal of a gas water heater.

I began by doing a bit of research and reached out to five different companies. Controlling Systems was the first company to get back to me, leaving me with an initial impression of their professionalism from their timely communication. I’m not sure if winter is a slow time for the industry or not, but I met with a consultant for a quote within the week. Chris P did a great job showing me various options along with their various rebates and incentives. The best part of the entire interaction was that he didn’t pressure me into the install. I’ve had consultants be overly pushy in the past and that’s a red flag for me and to start looking elsewhere. So I decided why not, and proceeded to schedule the install.

A week passes and the install day has arrived. To my pleasant surprise, there are 3 trucks and a whole team to work on the removal, electrical, and install of the water heater. This completely shattered my expectations set by previous contractors as I was use to seeing 2-3 crew members at most from other companies. They were quick and efficient with their work and I had a new water heater by the end of the day and 10 days after I began my initial research. I’m very impressed and hope to continue doing business with Controlling Systems for the foreseeable future.

These guys are amazing at what they do. Punctual, efficient, knowledgeable, and personable, always willing to teach and explain every step of the process. We have relied on Controlling Systems for a number of our home improvements / routine maintenance over the last few years and each time are thoroughly impressed with their work. Jim, Elijah, and Rudy came this time and expertly and expeditiously installed a heat pump + furnace. Pricing was fair and CS took care of applying for all the relevant rebates which made the process so smooth. Cannot recommend Controlling Systems enough!

Gemini, Elijah and crew did a great job installing a new water heater for us recently. They helped identify rebates we qualified for, explained the new features of our appliance, and answered our questions. Plus, they literally whistled while they worked - I
appreciate quality service completed by friendly & fun workers. Thanks!

Called Controlling Systems this morning when my furnace would not fire. They sent a technician, Chuck, over and he arrived about 3 hours later, and he was even 30 minutes early. He checked out my furnace and identified the problem quickly. He checked to see if it was available and what it would cost. The part was available and he could pick it up and install it later today. He was back in a couple hours, installed the controller and had my furnace running again. It was less than 8 hours from when I called until he had my furnace heating my home again. Controlling Systems was great to work with today and I even signed up for the annual maintenance program they offer.

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.

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.
