Most HVAC systems work by exchanging your house’s air with the air outdoors and you want to keep any pests out of your HVAC system. Holes in the exterior of your house for vents could mean possible openings where insects and other household pests can find their way inside.

However, you can reduce the risk of critters invading your house through the heating or cooling ducts with a few common-sense steps, including:

• Don’t let water pool near your outdoor air conditioner. Pests seek out water. Redirect the water away from the house. • Cover duct entrances. A mesh screen or louver can help close your ducts off to invaders while still allowing free air flow. • Keep your ductwork maintained. Gaps in ducts are potential entry points. Look for cracks or worn duct tape and replace or repair as necessary. • Control vermin or insects. Regular pest spraying can help keep problems away, particularly home defense sprays that are applied directly to your house around vulnerable areas to discourage invaders.

Regular professional maintenance of your system can also help identify problem spots where pests might get in.
