Your home comfort system is a machine, and like any other machine, it demands timely maintenance and good care. The same is also true for any other piece of machinery you'd ever come across, for instance, your car which needs timely cleaning, oil change, and whatnot.
Thus, it should come as no surprise that a home comfort system also needs regular preventive maintenance. You can make the best of things by getting a local HVAC service like Blue Valley Heating and Cooling on board.
It is in the IFGC + the IBC (International fuel and gas code + International building code) code book that a mechanical device needs regular maintenance section 102.3.
