Most people are aware of the need to service their vehicles on a regular basis with oil changes, spark plugs etc. but we often fail to give our heating and A/C units regular maintenance. We regularly adjust our thermostats expecting the system to cool or heat the house efficiently though we rarely if ever have the unit serviced. Most of us have no idea that our systems may be running on their last leg and we often find out at the worst times as they tend to breakdown right in the middle of winter or summer when we need them the most. Did you know a unit that is low on refrigerant, if ran in the winter, can cause your electric bill to soar through the roof? Some benefits of maintaining your system include: cleaner air in your home, less breakdowns during the year, and a longer equipment life span.
