How to Protect Your HVAC Systems from Pest Infestation

Various seasons bring different challenges in form of different pests. The HVAC systems are an ideal place for several types of pests. The damp and warm environment of these systems is very inviting for pests to make them their home. However, pests in your HVAC system can mean increased utility bills, repair expenses and severe health problems. Here’s how you can prevent pests in your HVAC system.

What are the Signs of Pest Infestation?

The first step towards protecting your HVAC system from pests is to look for signs of their presence. Certain habits and natural behaviors of pests leave signs. These include scratches on the walls chewed ducts and valves, droppings, feathers etc. Once you spot such signs of pest infestation, you need to identify the type of pests and the extent of the damage caused.

 What Kind of Pests Can Harm the HVAC System?

The 5 types of pests most commonly infesting the HVAC systems are as follows:

  1. Raccoons and Squirrels – These pests can easily chew through the ductwork and vents. The holes in ducts will allow warm and cold air to escape which will cause an increase in the utility bills.
  2. Insects – Dark and cool places are ideal hideouts for these pests. They may not cause major harm but dust mites may trigger allergy attacks and cockroaches are known carriers of diseases.
  3. Rats and Mice – Since rodents like to crawl into tight spaces, they can cause severe damage to your HVAC system. These pests often chew through refrigerant lines, duct material and other components of the system which might result in expensive repairs.
  4. Snakes – They are incapable of regulating their own body temperature and hence are drawn to the heat generated in the condenser units. They can die if the fan blades start and this may damage the blades and parts of the HVAC system. Keep in mind that long grass and unkempt yards are inviting for snakes. Hence always keep the exterior areas around the building free of overgrowth and weeds so that snakes don’t invade the HVAC system as it is easily accessible with its multiple openings and vents.
  5. Birds – Their droppings can accumulate and adversely affect the quality of air circulated through the air conditioner. They can choke the filters and the particles from the dried droppings can get sucked into the fresh air circulation. These particles can cause serious health concerns such as candidiasis, histoplasmosis, E.coli infection, cryptococcosis etc. Besides birds dwelling in and around an air conditioning system can peck off the insulation which covers the pipes and the debris such as feathers, twigs from their nests can conk off the air conditioner’s compressor.
