The various components of your HVAC system wear out over time. In addition, there have been a lot of advances in this area with equipment that is more energy efficient, as these systems draw a lot of electricity and gas to heat and cool the house. If your units are nearing the end of their life or are extremely inefficient in heating or cooling the home, it is probably time to replace the key components. The major components typically include the furnace and the air conditioning units.
Depending on the size of your home, you may have a singular set furnace and air conditioning units, but if you have a larger home, you might two or three sets of units. You might also need to budget for replacing your ductwork if the home is older.
