When do I choose replacement over repair for either my heating or cooling system?
Having your heating system serviced regularly will ensure it is running at peak efficiency. If one of the main parts of the natural gas furnace fails and it is costly to repair, you may be better off buying a new system, particularly if the furnace is older (i.e., has a pilot light). With a more efficient system, installation costs could be recovered within as little as three to five years.
Regular servicing of your air-conditioner could well extend its life. Again, if repairs are costly, upgrading to a newer, quieter, more energy efficient system may be the better answer and will save you money in the long run. Remember, though, that due to global concerns about ozone-depletion, chlorine-based refrigerants are being phased-out and will become less available in the future, so the cost to service an air-conditioner with such a refrigerant may rise dramatically. You might consider going to an air conditioner that has a more environmentally sound, energy efficient and cost saving refrigerant.
