Replace Your Air Filter Regularly
Nobody likes breath dirty air and it isn’t healthy for you or your family. If the home was sitting on the market without owners living inside, then chances are good that those air filters haven’t been changed in a while. Dirt and dust accumulate in the filters over time, making your HVAC system less efficient overall. Fortunately, you should be able to find replacement filters at your local hardware store such as Home Depot or Lowes. For more advice on HVAC maintenance, read our tips here.
