Everyone is familiar with the old adage “An ounce of prevention is worth a pound of cure.” This is especially true when it comes to the maintenance of expensive household systems like heating, cooling, and plumbing. It is easy to take these basic conveniences for granted, until a breakdown occurs and you are left without heat or air conditioning when you need them most. Worse yet is a plumbing failure. Problems that require the dreaded call to the plumber always seem to happen after hours, on a holiday, or with a house full of guests. HVAC and plumbing system failures are not only inconvenient, they can be costly.
