System is operating properly at this time and refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions however due to age of equipment multiple part failure is possible at anytime. Training rom system is fully functional and operating within manufacturer specifications at this time, refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions.
DCM2 complete; Heat; (12) F12242 and (2) F20201 replaced. Systems are fully functional. All components are operating within manufacturers specifications. Gas pressure and temperature rise are within design parameters. Refrigerant pressure and temperature are appropriate for indoor and outdoor conditions. Heat checklist attached.
Arrived to replace old single wall flu vent with Double Wall flue vent Photo attached
DCM2: AC complete, checked (3) 16x25x4 filters. Both systems are fully functional however not operating within manufacturer specifications due to indoor capacitor on basement system being out of tolerance and outdoor capacitor on main floor system being out of tolerance. Refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions. Photos and maintenance checklist attached.
DCM2: A/C complete, replaced (2) 16x25x1 and (1) 16x25x4 filters. Both systems are fully functional and operating within manufacturer specifications at this time. Refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions. Temp split 17* main floor and 16* upstairs. Noticed flue vent rusted out recommend replacing both flue vents due to hole in one and other starting to form rust. Recommend replacing with double wall instead of single wall to better insulate flue.

Main floor system is extremely low on R22 refrigerant. Saturation temp in indoor coil is 6*. Superheat is 64* Factory charge on unit is 10 lbs with an additional 3 lbs to account for line length and evaporator. Homeowner request quote to replace coils. Furnace is 7 years old and may be compatible with some cooling equipment.
