We bought a furnace back in 2010. Every year we have a tuneup performed before winter. We have never had a problem or bad experience. There are so many other items in which they have to offer. We also had our duct work cleaned. We just purchased a smoke, fire, co detector which the technician had on the truck and installed in just a few minutes after performing routine maintenance on the furnace. We are so pleased with One Hour Heating's professional services. We will always recommend them to friends and family.
