Smithville Furnace repair Upon my arrival I performed a 6 month checkup on 1 heat pump system. Flushed and treated the water removal system, washed the condenser coil using water, cleaned and treated the electrical cabinet then verified system safety and performance. I found that bacterial growth has started to form inside the air handler and on the air circulation system. I recommend having the indoor system cleaned then treated for bacterial growth. I will email over options for cleanings and options for bacterial prevention systems plus cleanings depending on the level chosen. Left a pamphlet on the refrigerator that goes over Solaris bacterial prevention system and the benifits it offers.
