Check the air filter if the thermostat isn’t the culprit. In addition to preventing dust and dirt from circulating throughout your home, it also catches mold, mildew, and other contaminants. It may be impossible for air to flow if the filter is dirty.
Professionals for heat pump installation in Weirton, WV, recommend changing standard filters every one to three months and high-efficiency filters every six to twelve months.
Closed vents and ducts can also restrict airflow. Even in rooms you don’t use that often, closing vents can strain your heating system since it must work harder to heat the room you just closed.
