The single best saying for preventative maintenance is just like owning a boat: “An ounce of prevention is worth a pound of cure.” When it comes to regular maintenance the long term savings add up.
For example, replacing the air filters in a HVAC system or refrigeration system. The immediate reaction for most people is “what’s the cost” and that is the tricky question. The cost of filters and having them changed on a regular basis is a fixed cost. The more significant question is how much does the regular changing of air filters save in electrical costs and premature equipment failure? Hidden costs caused by not changing air filters regularly is allowing dirt to accumulate on the cooling coils and in turn lowering the efficiency of the equipment (higher energy costs). Ultimately if the cooling coils are allowed to become dirty they must be cleaned to restore efficiency and this is another cost above and beyond inefficiency, premature failure and equipment that is not reliable.
Ultimately, ignoring regular maintenance will cost more in emergency service calls, energy costs and part replacement. Regular maintenance will not eliminate part failure, but it will keep equipment working as efficiently as possible during its usable service life.
