5 Stars 5/5

Great Product!

January 18, 2024

We bought a new system when our 2015 American Standard system failed in October. We were impressed with our furnace, but we're even MORE impressed now that we had 4 days below freezing in North Texas and our home stayed nice and warm! We felt comfortable the entire time, something we didn't get to experience last winter with our American Standard. It's much quieter and efficient, so we're recommending Lennox to our friends and family!

Excellent Furnace

I had one of these installed in my condo in 2019 and it has been amazing. It's much quieter than my previous unit and the filters are very easy to change. Highly recommend this furnace.

Excellent furnace, great value

July 26, 2023

I had eight of these furnaces installed in my apartment complex 9 years ago and I have not had a single complaint or issue with any of them. They appear to be very well made and my service man says they are easy to service and he likes them as well. Overall, I would definitely install more of these if I needed them.
