Scheduled visits, priority response between visits, a written condition report per unit and fixed labour rates for the contract year.
Is a compressor replacement guaranteed?
Yes. Replacements are done with a system flush and new drier, and both part and workmanship are warranted, provided the original cause of failure is corrected.
