While not always, you may notice an abnormal noise coming from the system, your heating or cooling system running non-stop, or warm air/cool air coming from the vents during the opposite season.   Abnormally high utility bills are also a common indicator.

Problems can be caused by a number of different factors.  The most common include:

  • Normal wear and tear associated with age.  As your heating & cooling system is nearing the end of its life cycle you may see an increase in maintenance bills.  This is a good indication that it is time to replace your system.
  • A failed part due to any number of reasons.  Routine maintenance on your heating & cooling system can sometimes head off these types of problems.  You can catch them before they become major problems.
  • Improper or poor maintenance.  Lack of maintenance also decreases the efficiency of your system and makes it more costly to run.
