Nationwide Home Comfort makes replacing your old HVAC system simple. The first step in changing your older HVAC equipment is to determine the appropriate capacity or output based on the size and layout of your home. Our representatives will then assess your older equipment to determine what parts need to be supplied or replaced. Some of the items may include: ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil. After these determinations are made our representative will price out your new unit and complete an energy assessment which will give you some expectations of the cost vs savings for your new equipment. A convenient installation date will then be arranged with you to install your new equipment.
