Tech arrived to problem call for upstairs system. Upstairs system is approximately 25 years old and services upstairs. Downstairs unit was only looked at to verify it was operational out of request for homeowner. Inspected indoor unit. Gas furnace was on, verifying thermostat. Furnace burners were on but no fan movement. Pulled fan cover and found motor extremely hot to the touch. Motor is seized, capacitor has failed as well. Spoke to distributors concerning fan motor, and motor is not being made and obsolete. Manufacture offers no replacement other than going elsewhere with a universal motor. Checked standing pressures for system and found system to be low on standing pressures. It is highly recommended that entire upstairs system be considered for replacement. Customer agreed to have install supervisor out today to discuss replacement options. Turned unit off at power switch. Made notice of flood protection and operations. System is NOT operational at techs departure. Thank you f
