Steel T Heating & Air Conditioning
In 1989 Ken Reister purchased Steel-T Heating as it was facing bankruptcy. He had a plan and a dream and knew that the company had promise and with hard work and the right people he could turn things around. By 1991 he had bought out both partners and the company had made a turn and was on the road to success.

His belief that if you provide the customer with superior service they will reward you with continued business proved to be correct and the poor reputation established by prior ownership quickly changed. By the mid 1990's Steel-T had established them selves as an industry leader in the residential new construction market.

Steve from Steel-T came out to replace a gas valve on my furnace. After examine and testing the gas valve he determined that it didn’t need replacing. He could have done the replacement and charged me for it but showed his honesty and integrity by not doing that. He explained things in detail while here. His professionalism, honesty, and competence was very impressive! I will use Steel-T in the future and will request Steve if possible,

I have had the pleasure to use Steel-T on two occasions now. Today I was visited by Josh and Steve. Josh was also the tech that visited me about two years ago. I can't commend these two enough. They are two of the most professional individuals that I have ever had the pleasure to have in my home. They were timely, polite, respectful and just great individuals. With the customer service these guys provided, I can't imagine ever using another company besides Steel-T. Thank you both for the excellent service and experience!

I really appreciate the quality and professional effort of Steel T when they installed a new Carrier furnace in my house this week. I was impressed with the efficiency and speed in which their team disassembled the old system and installed the new furnace and had it up and running by the afternoon. I have worked in commercial HVAC control systems and would highly recommend Steel T.

We've used Steel-T for years. Unfortunately, I made the dumb decision to go with someone else because of speed. They attempted to troubleshoot our issue, but ended up telling us we needed a new unit ($6,000+). We went back to Steel-T for a 2nd opinion, and the tech (Joe) found the root cause in less than an hour and had us up and running the same night.
Highly recommend Steel-T.

Very pleased with our experience using Steel-T. They were always up front with the type of equipment and what we would be receiving with our new furnace and AC install. Technicians were prompt, efficient and kept the premises clean during the install. After the install, the tech thoroughly went over the new system components and how to operate it. Highly recommend and will use Steel T again.

The installers David and Abi were very professional, courteous and thorough in their work. They put in a long days work and cleaned up completely when finished. The operating instructions they reviewed were complete and thorough. The equipment is running flawlessly and we are very pleased with the equipment, the installation and the service. We highly recommend Steel T.

These guys did a great job working on my furnace yesterday. Called them about installing a humidifier which they gave me a good price on the part and installation, but they also discovered that I had a small gas leak which they instructed me to contact excel to investigate further. Excel came out verified that I did in fact have a gas leak and turned off my furnace until it could be fixed. Called back Steel T and explained the issue and they were able to come back to my house within 30 minutes to fix the furnace and get it turned back on so the kids wouldn't get cold. Additionally, since

Dishonest!!! We called Steel T this weekend when our AC unit went out. I asked them what they charged to come out. $69. I said ok. A repairman came as promised and told us it would be $79 for a diagnostic fee. We were NOT told of this charge when we asked for service. So, just to recap: walk in door $69, look at u it for 5 minutes $79! Our unit is under warranty and the guy said we needed a new coil.. etc... he said the part alone costs $400 and that is covered under our warranty. Then he proceeds to tell us that with all the labor it would cost us $1200 to fix! Said it would take 4-6 hours!

The quality of Steel T technicians varies wildly. Some were incredibly knowledgeable and professional. Others...not so much. One installed a filter backwards (the next Steel T technician noticed the mistake). One broke our humidifier by overtightening and cracking a part. One ordered the wrong part which delayed our repair by weeks, and Steel T accused us of ordering the wrong part when we weren't even part of the conversation. For the prices they charged, we expected better and more consistent service. We have switched to a different service company.

I called Steel T for an A/C inspection and service based on their radio advertisements and a generally positive ratings online. This was not an emergecy call, so we scheduled a regular business-hours visit several days in the future. I was told to expect a $70 trip charge, and after inspection they would discuss the repair cost with me.

Their technician arrived within the appointment window, and was professional and appeared to be generally competent. He conducted an inspection of the A/C system, and a cleaning of the external unit (15 minutes washing the cooling fins). The total time was about

Sister in law recommended Steel T heating and A/C because the thermostat stopped working. They came the same day we called for service. They called 10 min out to let me know when they would arrive. Two very professional men arrived and fixed problem in less than ten minutes. Asked if system had filter and they took me to it and how to change it. Brought a new filter in and changed it for us. Very reasonable price with very professional workers who gave me a lot of extra pointers on keeping system running great.
Thanks Steel T you will be highly recommended

These guys are very slow to respond to any repair work or warranty work in a timely manner. I would suggest going with a company who has better service.

Steel T is great. We had another heating company that incorrectly installed a water heater for us, and Steel T was there the same day to fix the problem. They also helped us with our dispute with the other company.

They also recently installed a new heater in my old rental house in Denver. Great job, great communication, timely and perfect.

I arranged with Steel T to have their two-season maintenance package. Shawn was scheduled to come today, and as requested he called a half hour before arriving. He spent over three hours here, taking apart the furnace and thoroughly cleaning the blower and other parts. I have pets, so there was a lot of cat/dog hair and dander. He was wonderful, explaining in detail what he was doing and afterward listing all the performance results on the job sheet/receipt. It was very impressive. He answered any questions I had and I will be sure to ask for Shawn to be the one to return in the fall when it&apos
