Another company put in the biggest furnace that could fit in my basement (one for a home twice the size of mine), and of course there were problems. It kept breaking down, and even though it had a 10 year warranty, the other company charged me for the repair..which wouldn't have been necessary had the furnace been the proper size. Enter my heroes, 4 Seasons heating and air. While installing my a/c system, they asked me why I had such a large furnace, which wouldn't work well in a home my size. Aha! that's why it kept breaking down! They were incensed to find the other company was charging me for the frequent repairs (un named, they are out of business now), I was told it should have been free. They recommended changing my duct work, which alleviated the problem somewhat, and the next 3 times it broke down, it was fixed for free. They recommended waiting until the warranty expired to replace it so I could have the latest model, which is what we did. They handle the yearly maintenance on my a/c and furnace, and I find them to be honest and very responsive with fair prices.

Left a mess behind after they finish their work. How did effective compressor and they try to charge me a fortune to replace it under warranty. Had the ducks insulated and they covered up all the damper levers

4 Seasons installed a mini-split and replaced a ceiling fan in our master bedroom on the third floor. The work was somewhat more involved than anticipated but was done at the quoted price (which was reasonable). The workers were efficient and thorough and kept all areas clean. Very pleased!
