Today I came to Gary’s Okotoks home to perform the annual family plan ac tune up and inspection. The furnace is 18 years old and the ac system is 15 years old. The water heater that serves the domestic hot water and under slab heating in the basement was just replaced and is working well at this time. Family plan ac tune up and inspection: Upon Ac inspection and service I tested temperature drop, relative humidity, air flow, motor and fan, compressor, capacitor, contactor, evaporator and condensing coils, refrigerant levels, and general system operation. The 18 year old furnace is in fair condition however the exhaust / inducing motor is leaking condensate. The motor and condensate pan should be replaced. The furnace and duct work is very dirty and needs to be cleaned. The inside ac evaporator coil has mold on it and there is no air purification device. The mold can contribute to extensive health issues when breathed in. An air purifier is highly recommended. The external ac system
