Ken Reister purchased Steel-T Heating in 1989 and grew it into a full-service home contractor serving Englewood, Centennial, Littleton, Lakewood and Highlands Ranch. Today, we're the only home service company in Colorado to earn a place in the Carrier Hall of Fame.
We've won the Carrier President's Award eleven times — 2014 through 2022, and again in 2024 and 2025. But the only award that matters is the one a homeowner gives us by calling back the next time something breaks.
Here's what Denver neighbors said this season.
"Beyond amazing. My technician Nick was the friendliest, most informative and caring technician you could ever ask for. He went above and beyond — all in an effort to keep my equipment running longer and utility bills lower. Steel-T and Nick will be my go-to forever for any HVAC needs!"
"Our family has used Steel T for over 20 years at 4 houses. They are the best! Always professional, prompt, and knowledgeable. Whether it is the process of getting the quote, or the last little instruction on the thermostat, they are all great. Thank you Steel T!"
"This was my first experience with Steel T and they did not disappoint! The technician (Jose) was prompt, courteous and professional and quickly diagnosed and repaired my heating system. I won't hesitate to call them again if I do!"
Same-day service across Englewood, Centennial, Littleton, Lakewood and Highlands Ranch. If your furnace quit overnight or your AC died on the hottest weekend of the year, we have a 24/7 emergency line for HVAC.
