We have AC units with 15 year warranties. They are 3 years old.
The maintenance tech today said the ac blower motors is dirty and needs cleaning and it’s $800 total to do both units. He says the warranty requires ac blower motor cleaning every 2-5 years, depending on how dirty they get. In Phoenix we use ac 8 months of the year so they get dirtier quicker. Aren’t ac systems closed units or is this really necessary maintenance?
