Main floor system is operating within manufacturer specifications and refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions. Found gas valve not closing all the way allowing gas to leak from manifold/burners. Getting 2.1 on outlet with system off. Turned system on and opened and closed gas valve continuously. Checked for gas again none leaking. Gas valve wasn’t closing all the way however now it is, unsure how long valve will remain proper before slightly opening again. Part warranty 05/2030. Found dirt starting to build up on both blower wheels probably due to recent pipe work causi
