Today I came to Trudy’s Chestermere home to perform a furnace service before winter. Clearview installed the furnace, uv air purifier, electronic filter, tankless water heater, and water softener in December 2020, and installed the ac system in 2018. Furnace service: Upon tune up and inspection of the 5 year old system I tested and adjusted the gas valve, burners, gas pressure and temperature rise. Pulled and cleaned the flame sensor. Tested ignition system, inducing motor and assembly, blower motor and assembly, heat exchanger, humidifier, static pressures, tested and tightened all electrical connections, all safety switches and control board. The furnace is in excellent condition. The uv air purifier was not working. Upon inspection I found one of the power wires was disconnected. I reconnected the wire and the system is working again. The electronic filter is very dirty and needs to be replaced. The filter rack was very tight which I fixed and the filter moves easier in and out.
