How Your Furnace Can Worsen Your Allergies

Have you ever caught when you turn on your heating for the first time in the fall, you’re sniffling more than usual? While spring allergies usually get a harsher reputation, fall allergies are still very common and many people struggle with them. For some, fall allergies can be even worse than spring brisk temps affecting our immune systems and from starting up our equipment. This can leave you wondering, can furnaces make allergies worse in the U.S., or even trigger them?

While furnaces can’t lead to allergies, they can aggravate them. How? During the hotter months, dust, dander and other allergens can build up in heating ducts. When the colder conditions arrive and we turn our furnaces on for the first time, all those allergens are now distributed through the vents and circulate throughout our houses. Luckily, there are things you can do to stop your furnace from aggravating your allergies.

How to Keep Your Furnace from Affecting Your Allergies

    1. Get a New HVAC Filter. Frequently replacing your filters is one of the best chores you can do to help your allergies at any time of the year. New filters are ideal for catching the allergens in your residence’s air, helping to keep you in better health.
    1. Freshen Up Your Air Ducts. Not only do small particles collect in your HVAC filters, but in your ductwork as well. An air duct cleaning can help minimize allergy symptoms and help your HVAC system run more efficiently. When you schedule an air duct cleaning, our experts review and clean components like your supply/return ducts and registers, grilles and diffusers.
    1. Keep Your Furnace in Good Working Condition. Adequate HVAC maintenance and periodic checkups are another easy way to both enhance your house’s air quality and keep your system performing as effectively as possible. In advance of switching your furnace on for the first time, it tends to help to have an HVAC mechanic complete a maintenance examination to ensure your filters and air ducts are clean and everything else is in great condition.

Allergies and continuous illness can be frustrating, and it can be tough to learn what’s leading to or aggravating them. Here are some extra FAQs, including answers and ideas that could help.

Is Forced Air Harmful for Allergies?

Allergy sufferers are typically told that forced air heating may aggravate your allergies even more. Forced air systems can circulate allergens through the air, leading you to breathing them in more often than if you had a radiant heating system. While it’s correct forced air systems can make your allergies worse, that is only if you don’t take appropriate care of your furnace. Other than the tasks we mentioned previously, you can also:

    • Dust and vacuum your house often. If there aren’t dust, dander or mold spore particles to collect in your air ducts, your air system can’t transport them into the air, and you can’t inhale them. Some extra cleaning suggestions are:
    • Ensure your vacuum has a HEPA filter.
    • Dust in advance of vacuuming.
    • Clean your curtains periodically, as they are a typical collecto of allergens.
    • Don’t forget to clean behind and under furniture.
    • Watch your house’s moisture levels. High humidity levels can also result in more severe allergies. Humidity supports mold growth and dust mites. Adding a dehumidifier to your HVAC system keeps moisture levels balanced and your indoor air quality much healthier.

What is the Best Furnace Filter for Allergies?

Most often, HEPA filters are the best if you or someone in your family suffers from allergies. HEPA filters are rated to remove 99.97 to 99.99% of particles, including dust, pollen and dirt. These filters have a MERV rating of 17-21, depending on the brand or filter material. This rating reveals how well a filter can remove pollutants from the air. As a result of their high-efficiency filtration performance, HEPA filters are dense and can limit airflow. It’s important to touch base with Service Experts Heating, Air Conditioning & Plumbing to make sure your heating and cooling system can run right with these high efficiency filters.

Can Clogged Filters or Air Ducts Make Me Sick?

Clogged filters can harbor particles and allow poor quality air to move throughout your home. This also applies to filthy vents. If you inhale these particles it can produce sneezing, coughing or other asthma-related problems, depending on your sensitivity.

It’s recommended to swap out your HVAC filter after 30-60 days, but here are some indications you might need to more regularly:

    • It’s taking a longer amount of time for your system to cool or heat your residence.
    • You discover more dust in your house.
    • Utility expenses are going up with no obvious reason.
    • Your allergies are popping up more often.
    • Signs your air ducts need cleaning include:
    • The metal is coated in dust.
    • Filthy supply and return vents.
    • Mold in your furnace, air conditioner, heat pump or air handler.
    • Dust flowing from your vents when your HVAC system is running.
    • Your residence is often dusty, regardless of constant cleaning.
