Controlling Systems

I don’t usually write reviews, but Bailey did a great job today! I reported a slight odor in my house and he was able to find and seal a small gas leak where the rigid gas line connects to the flexible gas line as it goes into the furnace. He did this just as a part of my routine furnace maintenance. Also did a great job on the maintenance. Thank you!

Bailey with Controlling systems is competent, efficient and tolerant of my overly friendly dogs!

After two weeks of being without air conditioning during the first heat wave of the summer, I was thrilled to see Roman standing at my door. He was on time, and had called to let me know he was on the way! He started right in on getting my new a/c unit installed. He was joined by Genesis and they were both friendly, and knowledgeable. When they were done Genesis gave me a tour of the new unit and explained the features and the maintenance needed. I could not have been happier. This is the second time I have used Controlling Systems, and I have been satisfied both times. What makes this company stand out is that they are smaller, and from the people in the front office to Ryan in sales to the technicians in my home, it is obvious that they take pride in doing a great job!

We had a new evaporative cooler installed on our roof and the 2 gentleman that did the work were excellent!! Gemini and Eastman kept us updated every step of the way. They were very kind, courteous, and respectful. Not only did they do a great job of installing the cooler, but they explained in detail how to run it. They also left no mess behind. They cleaned up everything, they even vacuumed up everything from the sawing and hammering. I would recommend this company with 5+ stars.

Called late afternoon and tech could come next morning. Rudy arrived at time stated and gave me a courtesy call that he was on his way to my house. My system was not cooling as normal. He checked several parts on the unit outside and found all was functioning. He cleaned the exterior filter of the unit which was quite dirty. Then checked the unit inside and tested the airflow nd thermistat. He found the AC was cooling properly. So the outside cleaning fixed my problem. This tech was thorough and honest. Didn't need any new parts and was only charged the trip charge as quote when I made the call for service. I was very pleased to have my unit working properly and given honest information. I would highly recommend this company to others.

Mike and Gemini of Control Systems arrived on-time and were very helpful walking us through each step of the installation process. They did a great job of making sure the installation looked as good as possible and kept the working area clean. If you are considering a Ductless A/C or Heating, Control Systems has the best installers and service technicians we have worked with. Highly recommended as a Diamond level Mitsubishi partner in Denver.

The team was communicative and professional throughout the process. They answered my questions, and went above and beyond to ensure the old setup in my house was up to snuff after installing my new heat pump and mini split heat pump. They were friendly and helpful and the quality is great!

As always, Controlling Systems did a great job. I had them install a central air conditioning system along with a new furnace. They are not cheap but they are reliable, professional, and honest.

I would recommend Controlling Systems. I received several bids and theirs was the most competitive, so from a value perspective they were great. The install was a bit challenged and took a long time. The head tech Roman, worked a 12+ hour day into the night to try to make sure everything was finished, all while maintaining a friendly customer service positive attitude. The other techs were also great, no complaints.

After their work was done we noticed our hot water heater was leaking. I called and got a less than helpful reaction from the receptionist, but then someone called me back (James I believe) and said they'd send someone right over. A supervisor came over and installed two new connections, free of charge. That is the sort of service you hope for when you're spending massive amounts of money on a new HVAC and it was much appreciated!

As a side note, we also had them install an automatic (measures outside temperature and adjusta automatically) bypass humidifier. The cost was a drop in the bucket and it's done an excellent job maintaining higher humidity this winter. I recommend adding one of these!

Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. We got several estimates on a new furnace, A/C, and tankless water heater, and Controlling Systems definitely came with the most competitive offer and we are so happy with the work and final outcome. The whole crew was wonderful!
