Performed comprehensive tune-up on McQuay heat pump system. Inspected electrical connections and verified proper operation of the unit in heating mode. Cleaned condenser coils and filter, checked for water leaks, and confirmed proper voltage at control box. Noted existing thermostat lacks C-wire required for WiFi thermostat upgrade - would require either new wiring or installation of adapter module. Also inspected electric baseboard heating system, which is functioning normally. Unit is operating within specifications.
