How can you tell when it is time for HVAC replacement? There are many telltale signs that your furnace or air conditioner is on its last leg. If the thought has already crossed your mind, you have probably noticed at least one or two of these signs. Check out this list of sure-fire hints that it’s time to replace your home HVAC unit:

  • Your furnace or air conditioner has started making strange noises when it runs. Squealing, knocking and other new sounds emitting from HVAC equipment is usually a sign that a total system breakdown is imminent.
  • Your HVAC system runs a lot but doesn’t seem to maintain a steady temperature. When certain components begin to wear out or corrode, air conditioner and furnace performance suffer. This will also drive your utility bills through the roof.
  • Your furnace or air conditioner is more than a decade old. It’s important to know that many modern HVAC systems last longer than that. However, this long lifespan is possible only with regular inspections and maintenance. Few homeowners follow through with yearly appointments.
