Completed maintenance on Central furnace and both mini splits. I cleaned units and washed filters for the mini splits. I changed out the air filter for the central furnace. All systems are working within manufacturer specifications. I did talk with customer about when to clean the filters on the mini split heads and when to change the filter on the furnace. Due to the remodel going on, I recommended checking it every two weeks. After the remodel is done, we talked about having a duct cleaning and blower will clean complete to get all the remodel dust out of the system.
