Came out for no heat call on 2013 Amana AC/80% Furnace. Upon inspection found bad low pressure switch for furnace. Spoke about possibly looking into replacing equipment due to system being out of warranty, customer not interested. For current system recommended replacing pressure switch (part comes with high and low pressure switches together), blower cleaning, wet switch and Blue Tube UV Light. Customer approved pressure switch only. Called Daikin they will have part available tomorrow afternoon. Scheduled repair for tomorrow 2/6/26 2-5pm window. Came back out with new dual pressure switches and all new tubing. Installed and verified normal operations for low and high stage heating. System working properly at this time. Also changed out 20x25x1 filter 5% Military Discount (not a Home Care member)
