When was the last time you did a thorough checkup on your heating and cooling equipment? Do you know when it’s time to call an air conditioning contractor? Your air conditioner may seem like it’s working perfectly. The temperature in your home can be entirely comfortable, but what you don’t feel is the increasing amount of energy your air conditioner is sucking up due to its old age. Like your computer, your heating and cooling equipment will become less efficient over time. It may look as good as the day you installed it, but on the inside things are slowing down and expiring. The reality is, replacing air conditioning equipment that is 15 years or older, will likely result in significant energy savings.
