How to install central air conditioning yourself?

If the system need a b-vent (double-wall) flue, it must be cut in and installed now, so the space required below does not get included in ductwork. Double-wall flue pipe needs a minimum 1" clearance to combustibles. Which means all penetrations through the roof and flooring should be overcut to allow for this requirement. After that a sheet metal firestop must be fashioned to suspend the flue, make sure appropriate clearance, and secure the overcut holes. Flat sheet metal with a round hole matching the flue diameter is useful. Harsh in complete.

• Diy Hvac: Set your indoor gear.

Our example home has a centrally located mechanical space in basement. Very first put the furnace/air handler (AHU) in place allowing area for the return atmosphere fall becoming set up using one side and/or other of this device. In case the system could have main air-conditioning, the evaporator coil will then be set in addition to the AHU. The do-it-yourselfer a cased coil is the better approach to get. A cased coil is also more straightforward to access the coil inside for future maintenance. An uncased coil has to be constructed into the supply plenum ensuring that all-air diverts up through the coil, and tight sealed penetrations must be given to the refrigeration lines. Serviceability (cleansing) of an uncased coil is hard, at the best.

• Do-it-yourself Hvac: Prepare and put in the offer plenum

The is a larger, more square duct which sits in addition to the AHU or evap. coil. The utmost effective end is sealed with an-end cap. Our example residence needs a rectangular trunkline attached to the front side of this plenum and another attached to the rear associated with plenum. Cut-off the plenum therefore it is 1" down from roof. On the ground, cut-in and connect the toward front and back of plenum. The take-offs might have an , which is a flange that bends over in the plenum. Enhance the plenum up set up and connect with self-tapping screws.
