How to Keep Your HVAC System from “Bugging Out”

Summer in Southern California brings sun, fun, and…bugs. When it heats up outside, pests look for refuge inside. Although it may be tempting to just cross your fingers and hope that they don’t choose your home as their summer hideout, ignoring pest problems can have major consequences.

Many homeowners may not realize that an easy path into the heart of their home lies in the HVAC system. It is important to protect your home from pests that can cause structural damage or leave behind hazards that can negatively impact your health. Luckily, there are simple solutions to protect your HVAC system and its components from unwanted guests.

Duct, Duct…

Cracks, holes, or gaps in your duct system are an easy entry point for pests. Insects and, even mice, can squeeze through holes that are the size of a dime. In addition to damaging equipment, any droppings left behind by pests can lead to serious indoor air quality issues. If you discover any gaps or cracks in your ducts, we recommend seeking out professional services immediately. Investing in routine pest control services is a great way to prevent infestations. If you have had a recent pest infestation, you should have your ducts professionally cleaned to improve the air quality in your home.

Cover Your Vents

Pests are not above entering your home through flue pipes and exterior vents, because these cool, dark locations are ideal for building nests. Prevent pests from making themselves at home by installing vent covers on all exterior flues, intakes and exhaust pipes. Vent covers are also a great way to keep rain water out, keeping your vents/flues dry will prevent future mold issues.

Show Your Condenser Some Love

One of the best ways to protect your HVAC system is preventing pest access to the air conditioning condenser. Insects and vermin can cause significant and expensive damage to your exterior condenser by chewing or scratching the unit when they have access to it. Show your condenser some love by regularly cleaning the surrounding area and removing any debris. An easy way to wash is a mixture of mild soap and warm water to scrub the exterior of the unit. If you have a few furry friends running around, it may be beneficial to install pet repellants, which emit scents that deter. Spray the repellant on the condenser and its surroundings to deter unwanted pests from coming near your unit.
