Every year, when the weather gets colder, your HVAC system goes from being dormant for months at a time, to being used, sometimes, nonstop, depending on the climate. It is crucial to the longevity of your system that it is operating properly, one component not working correctly can impact the entire system, and cause further damage to other parts. The first thing you can do to help your HVAC system under any conditions regardless of the time of year, is to change your air conditioner filter. Your air conditioner filter is constantly absorbing all kinds of dirt and debris that can clog it, which makes it difficult to circulate the air throughout your house. Something else to take into consideration before the weather gets cold, is to look for signs of moisture. Moisture can be problematic around your vents and around your furnace, because moisture can lead to mold or mildew if left untreated. Typical signs of moisture are condensation, water droplets, and discoloration around wood, and if you see these signs, it’s time to call your HVAC professional. Another thing to do before winter is to run your furnace, and listen to see if it makes any sounds. If you hear it making any unexpected noises then it is a good idea to have your HVAC system checked out by a professional HVAC provider, and they will be able to diagnose any sounds you may hear. The most important thing you should do to prepare your HVAC system for winter is to form a good relationship with your local HVAC provider and have regular maintenance performed.
