When we think of the risks that pests pose to our homes, most often, our concern is that they will contaminate food or destroy wooden support structures. However, HVAC contractors know that they can also threaten your heating and air conditioning systems. The guide below explains the impact they can have, signs of their presence, and steps you can take.

What Pests Can Damage Your HVAC & How?

Mice

When trying to navigate around your home, these rodents often take advantage of the air duct system. In addition to leaving behind dirt and droppings, mice are notorious for gnawing at wires, insulation, and other vital HVAC components, which can cause the system to malfunction and create a fire hazard.

Roaches 

These bugs thrive in cool, dark spaces, such as air ducts. Though they don't typically damage your HVAC unit directly, they can affect the quality of the air that blows out with their excrement. 

Ants 

There's still debate over why ants are attracted to electrical equipment. Some studies suggest that the electrical circuits' heat attracts them, while others claim they like the sensation of the magnetic field in live wires. Regardless, an army of ants can build nests inside your HVAC unit, which can cause it to short-circuit.

What Steps Can You Take to Prevent This?

In addition to sealing cracks and gaps around the exterior of your home, keeping all food in sealed containers can eliminate one of the most compelling reasons pests would decide to take up residence on your property. 

Beyond this, you should arrange for an HVAC contractor to perform an inspection twice a year—usually in the fall and spring. Not only can a technician help prepare your system for the upcoming cold or warm season, but this is when pests are most active. These professionals will examine your unit for signs of damage—whether it is due to regular wear or is pest-related. If they spot droppings or teeth marks, they will inform you so that you can arrange for pest control. They can also clean out your system or install an air purifier to boost air quality.
