From boilers, chillers, cooling towers, fan coils, heat pumps, domestic hot water, make-up air units, pumps, risers, and building automation systems, this episode breaks down the major systems that condo boards and property managers need to understand.

Andy and Anthony explain why preventative maintenance matters, what happens when buildings delay repairs, why chillers and boilers need seasonal service, and how small issues can turn into major failures when they are ignored.

They also discuss the difference between preventative maintenance contracts and comprehensive contracts, what managers should look for when walking through a mechanical room, why clean mechanical rooms matter, and how plumbing failures and riser leaks can create major damage throughout a building.
