I performed a single heating maintenance on a 2020 heat pump system. I checked amps, capacitor, filters, electrical, cleanliness, and safeties. The system is in need of some major cleaning in the airhandler. The air handler is full of growth. This leads to poor air quality, added system stress, and odor production. Also, the evaporator coil is oxidized. This causes a reduction in efficiency because it reduces temperature transfer meaning it cost more to run the system. In these types of systems, growth is almost unavoidable. We are offering a long term solution to the growth build up with the u/v light. This light is used to sterilize the inside of the system fighting off the growth formations. I discovered that the outdoor capacitor is actively failing. This part is used to start the outdoor parts. I provided two solutions to this. One of the options is to go back with a generic capacitor with an average lifespan of 3-5 year with a 1 year part warranty or an industrial grade capacitor
