I was called out to Kathleen’s house for a Homecare maintenance. Kathleen has lived here for about 3 years so we performed a thorough evaluation. During the evaluation we discovered the uv bulb was burnt out and it needs replaced every 3 years, the system/house can benefit from an iWave, there isn’t any return ductwork in the 3 bedrooms which would help maintain the temperature better, the heat pump is a bit dirty, and a superboost would help protect the compressor.
