Today I arrived and met with Tom & his wife. I completed the fall evaluation of the homes HVAC system. I turned on heating and tested all functions of performance and tested the safeties. System performs well and is safe. I also washed the outdoor unit using water and treated the electrical compartment using electrical insecticide. I gave customer bacteria prevention options and at this time they are considering HH14C. Please email my estimate to them, they will talk over more seriously and call in with approval. Upon departure the system is left in cooling mode set to 76 currently 74 inside.
