Completed home care inspection. The system is two years old. The furnace is a Rheem gas furnace 4 ton. The AC coil is a Rheem 3 1/2 ton. Inside of the furnace was clean. The filter was dirty, but we changed it. The outside unit has minimum debris on the inside and on the coils. There is the number one breakdown of all systems, the cleaner it is the more efficient it will be. The system does not have UV protection. Upon presenting the options to the customer, they only approved changing the filter. The filter is a April air model 210 or 213.
