"When you consider their price, factor in the labor and parts warranty. This is included in the price! My elite boiler came with a 12 year parts and labor warranty. All I could get anywhere else was a 5 year parts warranty from manufacturer. When I compared them to my normal HVAC, horizon was a better value. Top notch company. Additionally, any add-ons were already added. (Chimney liner, old boiler removal, etc.) Very pleased and will use them again. Oh and did I mention they worked from 7:30am till 10:15pm to get the job done? I was told it would take a week to install by others!"
