Performed single system heating maintenance on a 2024 gas furnace. The system has a 10 year labor warranty. I checked amps, capacitor, replaced the filter, flushed the drain with water only, examined the cleanliness, and tested the safeties. The system is heating to manufacture specifications. I recommend that a surge protector and air scrubber be added to the system to assist in maintaining cleanliness and to protect the components inside of the furnace. Also, I recommend a drain treatment with chemicals to prepare the drain for cooling season.
