Summers in Indiana are defined by high temperatures and soaring humidity. That makes our environment a breeding ground for bacteria and germs of all varieties, and they can easily infiltrate your home to cause all manner of mischief. In fact, germs and other biological contaminants can cause a lot of damage in the summer, since we keep our doors and windows locked tight to preserve the cool air generated by our air conditioners. Since HVAC systems circulate the air in your homes when they run, that means the contaminants can stay there for a long time, leading to that stagnant musty feeling in your house as well as passing colds and other illnesses between different family members.
