Every once in a while, you may see a trail of insects marching along an indoor windowsill or catch a rat scampering around in the attic. If rodents and other pests can get inside your home, then you bet they can burrow their way through your HVAC equipment—especially heating and cooling equipment that’s not properly maintained.

Feces, urine and other debris from pests are quick to clog air filters, making the air smell bad and resulting in poor indoor air quality. This can lead to health problems for everyone in your household. What’s more, some pests can damage HVAC components and home structures with their teeth and claws. Repairs will cost you time and money, and headaches are inevitable. Here are some tips for how to pest-proof residential HVAC systems in Oregon City, OR:

  • Seal leaky ducts: While leaky ducts may be a reason for high energy bills year-round, they also let in pests. Even the slightest opening can be an entry point for pests to get into HVAC equipment or the walls of house, so be sure to inspect your ductwork and seal any gaps, cracks or holes you can reach. If you suspect you have a number of leaks in your ductwork, consider hiring a professional duct sealing service.
  • Take control of moisture: Because some bugs and insects are attracted to moist areas, make sure to take control of any dampness inside your home and around heating and cooling equipment. This includes heavy condensation, puddles, steady water drips and spills.
  • Install vent screens: Does your home have external air vents? If the answer is yes, take the time to cover them with pest-proof aluminum wire mesh—the air vents are a vital part of your HVAC system and cannot be sealed shut. These screens, when properly installed and in good condition, act as a barrier, denying pests access to your HVAC equipment.
  • Spray often: All sorts of pests will try to get inside your home or your HVAC unit in search of food, water or shelter. To keep pests away, spray the perimeter of your house and around outdoor HVAC equipment twice a year. Consult a professional if the problem is recurring or located inside your home or ducts.
  • Inspect regularly: It’s important that homeowners perform their own seasonal or monthly HVAC inspections to ensure all heating and cooling equipment is free of pests or evidence of pest-related damage. Keep an eye out for the signs of a pest infestation, such as droppings, urine, dead critters and property damage.
  • Call a professional: Your HVAC maintenance appointment will consist of more than a simple equipment check. Your technician will clean and clear the space around the unit and take a close look at potential problem areas and be able to identify signs of a pest infestation.
