There are five main questions that need to be considered when deciding to either replace or repair your heating and cooling system:

  1. How old is your system? If your system is more than ten years old, it may be wiser to invest in new, higher efficiency equipment, which could cut your energy costs by up to 40%.
  2. What is the efficiency level of your current system?
  3. What was the efficiency when the system was new? Unfortunately, replacing parts of your old system will not improve the efficiency. If the energy savings of using a higher efficiency system will cover all or part of the cost of investing in new equipment, you should seriously consider replacement of the old system.
  4. What is the overall condition of your system? If your system is in solid condition, it could be wiser to simply repair it. But if your system breaks down often, you should consider replacing it. Consider the 50% Rule.
  5. The 50% Rule- If the cost of repair vs. replacement of your system is less than half of its value and you haven’t been suffering the financial burden of frequent service calls to keep your system up and running, repair may be easier on your checkbook . Ask your technician to calculate the efficiency and energy usage of your system to help make a determination.
