Get matched with top furnace / forced air heating system install or replace pros in Denver, CO

"Don was excellent. He performed a very thorough inspection of my system and clearly explained all his findings. My furnace is 20 years old, and despite finding many smaller issues he was not pushy about replacing the entire thing. He just gave an honest assessment of the condition. Don correctly found the issue with the blower (bad controller board) and fixed the cause of the failure (plugged drain pipe, causing water damage). After replacing the board the furnace is back up and running. I'll be giving them a call when it is time to replace the furnace."

"Very professional. They did an annual service check on my furnace. While doing so, they found that my filter was wrong and could have caused major damage to the furnace. They were able to find me the correct filter in a timely manner. I'll be calling them whenever something is wrong or I need another furnace cleaning/check."

"Bryan, the technician was really good. He explained what he was doing and why. He was able to diagnose and repair the problem quickly. He also took the time to explain how a number of the components work and what I could do to keep the furnace in good order between maintenance intervals. I highly recommend Behold Heating and Cooling."

"Late on a Friday night my furnace stopped working. I called Dale and he walked me through the furnace and diagnosed my problem over the phone. He was spot on with the diagnosis, and I got a new fuse and the furnace started working again. Dale is very professional and wants to help."

"My furnace stopped working and my house was at 56à ° After I posted on Nextdoor looking for a recommendation,Tony reached out to me and offered to come take a look. He came right away, knew exactly what he was doing, determined the issue, ordered the part and had me back up and running with glorious heat in no time! Being that my house is 20 years old and has the original furnace and A/C unit I wanted to get an estimate of what it might cost me to replace both. . He gave me what I believe to be a very fair price and I WILL proceed to have this service done in the spring when I have the funds. I will also be the first person to highly recommend Tony for anyone needing the services he can provide. Heâ  s a rock star in my eyes!!"

"Called got a appointment right away came out checked all my heating needs explained everything about my furnace. Highly recommend this company I give them a five star and the service man that came out was excellent I give him five stars he's the best and very caring and does excellent job."

"Habib is seriously the most thorough professional we have ever had! He expertly explained the new AC/furnace system to us so we knew precisely how the system worked, before he installed anything. He was so considerate and enthusiastic and he loves helping his customers. Our A/C unit worked so well and I know our brand new furnace will be great this winter. If I could give him 10 stars I would because he was so knowledgeable and conscientious!"

"Arrived on time and did an excellent job of Heating system maintenance."

"The repair was made.  Sean, the service tech was courteous and professional and obviously knew what he was doing. He replaced the circuit board which took less than 1/2 hour and for that I was charged $597.00. Thinking that the circuit board was pricey (Sean, the service tech indicated so), I thought the repair bill of $597 was reasonable.  Only after calling some stores (the next day) and finding out a circuit board cost $125 did I realize I got ripped off. Controlling Systems labor charge for 1/2 hour work amounted to $472. I called the owner/guy in charge to request a refund for part of the labor charge. (I really didn't expect to receive anything) Not only did this person(whose name I wished I remembered, I would state it here) not want to hear my complaint, he hung up on me because he knew he ripped me off. He was rude and didn't want to hear my complaint. He obviously didn't want to hear anything I had to say, only stating that I agreed to the repair charge beforehand. To that he's correct, I did agree to the charge but when I asked Sean what was the cost of the circuit board, he said  $250-300. Now I know parts are marked up when purchased through a company such as CS but I still believe this company took advantage of me. ( and probably hundreds of others out there). Controlling Systems did not provide parts cost, labor costs, etc in their estimate which they used to (I had used them 3 years ago, but I won't ever use them again) Future potential customers take heed: I WOULD ALWAYS REQUEST THE ESTIMATE REPAIR BILL BE BROKEN DOWN to parts cost, labor cost, etc. And if they tell you they can't provide that, that's a good sign you're being overcharged.
Normally I am careful about negotiating and reading the fine print, etc. but this day I was distracted and the temperature was in the teens. I wanted the furnace fixed and I didn't have time to get estimates. Also if I hadn't  used Controlling Systems I would have been charged the $100 diagnostic(service) charge. Lastly, Sean intially quoted me $700. When I told him I was going to get other estimates, he lowered the estimate to $597.
