I'm very happy with my new high efficiency furnace and power vent water heater. Of the three quotes that I got before the install, Brantworth was the only company that was knowledgeable enough to inform me that I would need an upgraded water heater if I installed a new furnace because my old water heater would not be able to safely vent to the chimney on its own without the furnace connected. On installation day, they arrived around 8:30 am and got right to work. It was a big job for a very small area but they did an excellent job and I'm very happy with how it all went. The installers were very hard working, polite and courteous. I would definitely recommend this company for any heating and cooling needs.
