Today I came to Shawn and Rebecca’s (mother in law) Cochrane home to perform an ac tune up and inspection. Shawn also said there is some fan noise on the out side system. Upon inspection and tune of the 7 year old system I tested temperature drop, relative humidity, air flow, motor and fan, compressor, capacitor, contactor, evaporator and condensing coils, and refrigerant levels. The the system is in relatively good condition. The furnace is from 2010 and appears in ok condition however the blower motor is over amperage and leaking oil. This will result in failure. The furnace and duct work are quite dirty as is the ac coil (see sample) and should be cleaning. The outside ac system was very loud. This was caused by a loose fan amount which I tightened and the sound is gone, should it return the bolts will need to be re tightened. The started capacitor system is rusted indicating impending failure. The compressor, fan and contactor are all working well within manufacturers specification
