Oregon’s spring season has beautiful scenery, from colorful wildflowers to lush, vibrant greenery. But as flowers and trees start to bloom, they also release allergens, like pollen and mold spores. When these particles make their way into your home, they often increase sneezing, itchy eyes and congestion. Prepping your HVAC system for allergy season is one of the best ways to improve indoor air quality and stay more comfortable.
When Does Spring Allergy Season Take Place in Oregon?
Oregon’s spring allergy season usually takes place from late February through early summer. Here are the most common allergens:
- Alder tree pollen
- Birch tree pollen
- Maple tree pollen
- Oak tree pollen
- Grass pollen
- Mold spores
- Cottonwood fluff
- Juniper pollen
How Does Your HVAC System Impact Spring Allergies?
Your HVAC system is constantly circulating warm or cool air throughout your home. When it receives proper care and attention, it contributes to cleaner indoor air with fewer allergens. When neglected, it makes indoor allergies worse and living spaces very uncomfortable.
Dirty Filters
When it comes to indoor allergens, think of the HVAC system as a body and the air filter as the lungs: when it’s dirty, the HVAC system can’t breathe. This ends up causing pressure issues within the system and dirtier air quality.
Dirty Ductwork
You can think of the ductwork as the circulatory system of the HVAC system. It allows conditioned air to flow into each room evenly and efficiently. But over time, lots of dust and other allergens can collect inside the air ducts. Until you have them cleaned, these particles will mix with the air you breathe as it’s pushed into each room. If you’re having to dust or vacuum more than usual, this is a red flag for dirty ductwork. Musty odors coming from your supply vents can signal mold growth in the ducts, which is also harmful to allergies and respiratory health.
Leaky Ductwork
Leaky ductwork can be just as problematic as dirty ductwork. The gaps and cracks allow allergens to seep in and mix with the conditioned air that gets pushed into each room. Even small gaps can lead to major energy loss and worsening allergy symptoms.
Clogged Condensate Drain Lines
Your AC does much more than cool your home. It also helps keep the indoor humidity levels balanced. It does this by pulling moisture out of the air. The condensation then flows through a condensate drain line and outside of your house, where it belongs. When the line clogs from algae or dirt, this messes with the system’s ability to drain properly. The water may back up into the drain pan, resulting in damp insulation or damaged drywall. The moisture then creates the ideal conditions for mold growth, which hurts indoor allergy sensitivities.
The Best Ways to Prep Your HVAC System for Allergy Season
The steps you take today can make a big difference in your symptoms during the next spring allergy season. Some homes may need nothing more than equipment cleaning and tune-ups, while others may require certain upgrades to stay protected.
Swap Out Old Air Filters
Start spring the right way with a clean air filter. For the ultimate protection against allergens, consider using a higher MERV rating. Just make sure to check system compatibility. The higher the MERV rating, the more air resistance the filter creates. If your HVAC system isn’t compatible, the filter will end up making the allergy problem worse instead of better. Incompatible filters can also shorten the lifespan of your unit.
Wipe Down Supply and Return Vents
Do a walkthrough of the home to make sure all vents are open. Wipe them down using a damp microfiber cloth or gentle cleaning spray. Take a vacuum and suction deep inside the vent openings to remove clinging dust bunnies and hidden pet hair. This simple step boosts your air quality by making sure irritants don’t hitch a ride on the airflow.
Have Ductwork Professionally Cleaned and Sealed
Spring is a great time to get your ductwork cleaned, especially if it’s been more than a couple of years. Professionals have special-grade cleaning tools that remove deeply embedded dust, hidden pet dander and stubborn pollen buildup. With the ductwork clean, the air will circulate more freely, meaning fewer allergens and less dust settling on your furniture.
Install a Whole-Home Air Purifier
Targeted allergen protection is available with a whole-home air purifier. This type of system connects to the HVAC system, delivering cleaner air in each space through an air vent. Some versions can even eliminate certain viruses and bacteria.
Install Whole-Home Humidity Control
With proper humidity balancing, it’s much easier to keep allergy symptoms under control. We can add a whole-home humidifier or dehumidifier. Your home’s unique layout and indoor conditions determine which setup is best.
How whole-home humidity balancing improves allergy and respiratory health:
- Clears the air of pesky allergens
- Stops hidden mold before it starts
- Soothes scratchy throats and sinuses
- Keeps tiny dust mites far away
- Makes every breath feel much easier
Double-Check Thermostat Settings
During the spring in Oregon, it’s very normal to be cool in the morning and much warmer by evening. You may need to update your thermostat settings to match the temperature swings. Installing a smart thermostat with adaptive technology can automate temperature adjustments according to real-time weather conditions. Some models even come with air quality sensors that alert you to high pollen counts.
Clear Leaves From Outdoor Unit
Check the area around the outdoor part of the HVAC system. There’s a good chance winter weather created quite a mess, leaving leaves, twigs and other debris cluttered against the unit. Taking time to remove this organic buildup ensures the condenser has room to breathe. A 2-foot clearance on all sides is the goal. A condenser that operates at peak efficiency contributes to fewer indoor allergens by preventing the house from getting stuffy.
Gently Clean Indoor and Outdoor Coils
HVAC system coils do the heavy lifting for heating and cooling a home. Cleaning them regularly is crucial to making sure they complete the heat transfer process efficiently. Any type of dust or grime buildup on them will prevent the system from properly managing the temperature.
Cleaning the outdoor coils is simple:
- Shut off the system’s power
- Remove any surface debris
- Gently rinse the coils with water
- Apply approved coil cleaner
Flush and Clean the Drain Line
Keeping the drain line clean ensures condensation can flow freely from the drain pan to the outside of the home. Flushing it with distilled vinegar or warm soapy water during spring stops algae growth and prevents clogs from forming.
