Upgraded my 20 year old furnace to a high efficiency unit after checking out several vendors. High Efficiency wasn't the cheapest option but I opted for the Carrier brand reputation & the sales approach by Charton who was easily the best as he gave me complete confidence in how the furnace would be installed. The venting was very complicated but he detailed it perfectly. The other companies were not as specific leaving me questioning what the ceiling in my finished basement would look like. Just needed a small inconspicuous grill The installers came ready to work and completed the installation efficiently, in a timely manner and answered my questions. Cleanup afterwards was as expected. This company knows their stuff!! VERY IMPRESSED!!
