Bring a sheet of duct board, programmable thermostat, horizontal drain pan, two forms of water safety, will need to move existing Apco to the new air handler.
Bad board caused a fault in relays as well causing heat strips to stay energized and fan on continuously. The system is old, full of mold and runs on refrigerant being phased out by the EPA in 2020. Recommend replacing the system. The model number of current carrier air handler is NFCX4800C1 and serial is L995162224. Customer will think over options and call us back
Replacing board and 2 sequencers.air handler working properly. New board and heat strips installed. During testing noticed outdoor unit not running. Outdoor heat pump off on low pressure due to completely empty of refrigerant. Fins of outdoor coil corroded and leaking. System will not hold a charge due to the size of the leak. System is r-22 refrigerant and will be unavailable Jan 2020 due to EPA regulations. If heat pump is replaced the evaporator coil upstairs will also have to be replaced do to the pressure difference and the inability to flush r-22 out of the coil. All new systems use 410a refrigerant. The two options to fix the situation are to replace the heat pump and the upstairs coil or replace the entire system which is the recommended action because of the warranty and efficiency difference. Heat is operating solely on emergency heat and the outdoor unit will remain inoperable until it is replaced.
Heating Repair: Guest house upstairs system heat was staying on. Diagnosed problem with control board and high voltage strip heat sequencers. Gave 3 options to replace bad parts in existing air handler or the entire system. Service call price will be dropped with an installation
