I signed up for their maintenance program. They came out in Feb 2021 and cleaned the drain pipe only for it to get clogged in 2 months again, now they want to charge me for something I feel was never really done. Knowone really verifys if items are really done they just check off things as done, make the owners feel like their receiving a service never completed. Very disappointed! I replaced my home unit with them on another property can only wait to see what troubles I have with that unit.
