Your Sunday chore list has plenty on it–pluck the weeds in the garden, power wash the porch, etc., but while you tend to the miscellaneous books and crannies of your home, your HVAC system and plumbing are slowly breaking down.
We call it wear and tear–damage that accrues over time as a result of use. Your car gains miles, your floors get scuffs and scrapes, and your home systems slowly lose steam. Your whole home needs a little TLC, and this is why.
