Summer is us, and that means rising temperatures and giving our air conditioners a workout.  Our air conditioners, like our homes, need preventative maintaince in order to continue to run efficiently.  At first sign of use, or damage, take care of the problem.  Most issues will not resolve themselves, contrary to what we hope.  This is good advice, and not just for your heating and cooling.  Roofs, walls, floors, all can benefit from some care so that they last long into the future.  Remember, your home is a big investment, tend to it on a regular basis.
