How Do I Go About Pest Proofing?

Pest proofing your HVAC system can prevent many unwanted headaches. Keeping pests out and protecting your HVAC components is a must. But how do you go about pest proofing your system?

1. Seal your ducts
Your duct system can be a major point of access for unwanted critters. Gaps, cracks and larger disconnections will create opportunities for pests to get into your unit and your home. They can also cause damage to your ductwork and indoor air pollution with dander and droppings left behind. If you already have a pest invasion, trapping is a better option than poison. Using poison can cause the pest to die and decay in your duct system. Once the invasion is under control and cleanup is complete, seal off any and all gaps in your ductwork. This should be done professionally.

2. Install flue and vent covers
If you have a furnace, then you have a flue. It expels byproducts of combustion, and protects you from getting carbon monoxide poisoning. Chipmunks and birds in particular like to enter the flue pipes. They can perish there and block the combustion byproducts from exiting through the flue, which could lead to carbon monoxide poisoning. A flue cover is a very important step towards pest proofing your system.

Fresh air intakes and other exterior exhaust vents also need to be covered to prevent infestation. These areas are an ideal nesting location for pests. Additionally, these covers also keep rain water out of your vents. Just be sure to secure them tightly.

3. Protect your condenser
Your condenser unit, located outside, is also vulnerable to pests. Keep the area around the condenser clear of brush and debris to deter pests from making nests. They can damage the unit by chewing, scratching or even urinating. Clean the exterior of the unit as well as surrounding area with warm water and mild soap. You can also use a pet repellant to deter animals from coming near the unit and you don’t risk pesticide exposure.
