I arrived for a blue member fall maintenance on two system. I Inspected the upstairs system and checked all electrical components and filter to be in good condition. I found some growth in the system and cleaned with rags and cleaner. I then inspected the downstairs system and found the system to be in the same condition as the upstairs system. I then inspected the heat pumps and found them to be running properly. I recommend to install UV lights in the auto keep the systems clean. The homeowner wants to hand cleaning the air handler monthly on their own.
