High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace are the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
Has another company told you that your furnace has a cracked heat exchanger? The heat exchanger is the heart of your furnace. Its failure can result in a dangerous situation for your home and the best solution is usually a new furnace. Because of these issues, Bonney takes this situation very seriously. We will offer you proof of the cracked heat exchanger in the form of a picture from our video inspection camera or a report from our exhaust gas analyzer, before we make our recommendation.

Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs (Photo 3). A blown fuse is a sign of a failing part inside the condensing unit. So don’t just replace it and think you’ve solved the problem. Instead, replace the parts we show here. Then install new fuses and fire up the unit. If it blows again, call a pro—you’ve got more serious issues.
I just finished fixing some skylights on my parent's house. They had the bubble type that started leaking after the roof was resurfaced. After investigating it carefully, it became apparent that when the roof was resurfaced, the edges of the skylight were covered with a sealant. (To help prevent leaks perhaps?)The problem was that this coating sealed up the weep slots along the perimeter of the aluminum frame. These slots are key to proper operation of the skylight. The skylight dome isn't sealed to the aluminum frame. The frame is designed with channels that direct any water that manages to flow between the bubble and the frame back out through weep holes.Make sure those weep holes are clear! They can be blocked by dirt, ice, or a well-intentioned roofer.

I have a 90% efficient forced air gas furnace and when it was installed 4 years ago the guy didn't hook up a fresh air intake pipe allowing the furnace to draw in air from the hallway(slab home). My question is there are two holes for intake and I need to know if I should use one for the intake and block off the other or does it require two pipes? There is already a 2 exhaust leading outside thru wall.
