Allergies & Asthma: Your Home’s HVAC System Can Help You Breathe Easier

Posted On May 20th, 2019 by Omnispear Developers

Do you remember last spring - the spring of 2018 - when so many of us here in Central Illinois were slammed by a sudden attack of the sniffles? A cold, snowy winter lasted into April and when the thaw finally came - so did the pollen and hay fever. The Herald & Review over in Decatur even wrote an article about it, headlined THE BIG SNEEZE.

Hey, Champaign County, let’s not go through that again. Allergic reactions and the potential for asthma attacks are serious health concerns. We can’t help the weather, of course, but homeowners can drastically lower the risk of bad seasonal allergies by ensuring their family breathes clean air from high-quality, well-maintained HVAC systems - particularly the “ventilation” part.

A few simple preventive measures with your home’s HVAC unit can eliminate many of Central Illinois’ most common household allergens - dust and house dust mites, grass and tree pollen, pet dander and fur, mold and fungus spores, etc. - so your family can breathe easier all spring and summer.

Keep your HVAC system clean. Sniffle-starters like dust, dirt, dander and pollen collect on your home’s surfaces, ride along air currents and build up inside HVAC ductwork. If you like breathing clean air, as we all should, a little spring cleaning goes a long way.

  • Change the HVAC filter at the recommended frequency (usually every six weeks) and use a filter with a MERV score of at least 8 to remove microscopic particles. If your HVAC unit has a permanent filter, have it professionally cleaned.
  • Remove dust from air intake vents and floor registers.
  • Hire a licensed professional HVAC contractor to clean dirt out of the ducts.

Keep indoor humidity low. High moisture content in the air attracts a host of allergens, especially dust mites, according to an article published by ACHR News entitled “Allergies, Asthma and the Role of HVAC” citing research presented at the 2001 IAQ (Indoor Air Quality) Conference. Dehumidification reduces water vapor levels, thereby avoiding environments conducive to mites, molds and fungi and preventing triggers for allergies and asthma.

Keep pollinating plants, trees and bushes away from the outside A/C condenser. Air conditioning technology works by literally changing (heating or cooling) outdoor air and moving that changed (conditioned) air indoors. If the air entering your home is carrying pollen, it could eventually circulate around the house and cause allergic symptoms. Maintain a sizable buffer around the exterior condenser tank so your home can breathe clean air too.

Keep your HVAC system up-to-date on its maintenance schedule. This is our top HVAC tip for springtime air purification and allergy prevention. Professional maintenance performed on your home’s ventilation system - in which we clean ductwork, check for leaks, improve airflow and ensure optimum A/C operating efficiency - is arguably the most effective way to keep allergies and asthma at bay.
