Install new 80% furnace with AMS furnace of equal size and blower capacity. Includes transitions to ducting and vent connections. Arrived onsite removed existing furnace. Installed new furnace secured it to the ducting. Sealed up all of the joints properly. Hard piped the gas line into the furnace. Redid the venting with the correct 4 inch venting. Connected the ducting with S and drive. Hooked up the line voltage and low voltage. Installed the new thermostat and programmed it correctly. Confirmed the operation of the furnace. Checked for co at nearest register. Thank you for choosing CPI Plumbing and Heating Inc.
