Make sure your HVAC filters are always clean
Most new houses come with a central heating and cooling system that will keep them warm during winter and cool during summer. These systems usually have filters to keep dust or bacteria from flowing. So, it is important to clean or change these filters regularly, because otherwise, they can interfere with the correct functioning of the HVAC system.
The system can become inefficient if the filters and in a bad state, and this can end up costing you more. Moreover, damaged filters can end up circulating all the dust and bacteria through the air and cause negative effects on your health. If you live in a rented house or apartment, ask your landlord about its upkeep.
