Heating & A/C…Day 10

Mark from American Air and his crew were back yesterday plumbing natural gas lines and finishing up the installation of the furnace and central air conditioner. The first photo below shows the furnace assembly with the air conditioning lines plumbed to the evaporator coil and the condensation lines run to the floor drain. They were pulling a vacuum on the system as I visited around noon and planned to have cool air in the house by the time they left yesterday afternoon!

Mark spent most of his morning working on a natural gas distribution system attached to the side of the furnace assembly. The manifold he built distributes natural gas to 7 different devices in the house including the furnace, the cooktop, two fireplaces, the dryer(s), and the forced air heater in the garage. The goal is to have an easily accessible gas distribution manifold that includes clearly labeled lines and valves. The length of some of the gas lines and the number of (possible) appliances requires dividing the house into three separately regulated “zones” (two inside…one for the garage).
