Your Furnace Can Be Making Your Allergies More Severe

Have you ever felt when you start your heating for the first time in the fall, you’re sniffling more frequently? While spring allergies seem to get a more severe reputation, fall allergies are still very typical and many people struggle with them. For some, fall allergies can be even worse than spring thanks to cooler weather weakening our immune systems and from starting up our equipment. This may leave you considering, can furnaces make allergies worse in Tempe, or even cause them?

While furnaces can’t lead to allergies, they could aggravate them. How? During the hotter months, dust, dander and other debris can collect in heating ducts. When the winter conditions start and we flip our heat on for the first time, all those allergens are now pushed out of the ductwork and circulate throughout our residences. Thankfully, there are things you can do to keep your furnace from worsening your allergies.

How to Keep Your Furnace from Worsening Your Allergies

  1. Change Your HVAC Filter. Frequently replacing your filters is one of the best chores you can perform to help your allergies at any time of the year. Fresh filters are better at snagging the allergens in your residence’s air, helping to keep you in better health.
  2. Freshen Up Your Air Ducts. Not only do small particles collect in your HVAC filters, but in your ventilation as well. An air duct cleaning might help reduce allergy symptoms and help your HVAC system perform more efficiently. When you call for an air duct cleaning, repair techs review and clean components including your supply/return ducts and registers, grilles and diffusers.
  3. Keep Your Furnace in Good Working Order. Quality HVAC maintenance and routine service are another great way to both strengthen your residence’s air quality and keep your system working as efficiently as possible. Prior to flipping your heat on for the first time, it tends to help to have an HVAC mechanic complete a maintenance checkup to confirm your filters and air ducts are clean and everything else is in good working order.

Allergies and continual illness can be annoying, and it can be tough to discover what’s leading to or worsening them. Here are some additional FAQs, complete with answers and ideas that can help.

Is Forced Air Harmful for Allergies?

Allergy sufferers are usually told that forced air heating may affect your allergies even more. Forced air systems can push allergens through the air, resulting in you breathing them in more regularly than if you had a radiant heating system. While it’s correct forced air systems may make your allergies worse, that is only if you avoid suitable upkeep of your heating equipment. Other than the tasks we included above, you can also:

  • Dust and vacuum your residence regularly. If there aren’t dust, dander or mold spore particles to clog your air ducts, your air system can’t carry them into the air, and you can’t inhale them. Some extra cleaning ideas include:
    • Ensure your vacuum has a HEPA filter.
    • Dust before vacuuming.
    • Clean your curtains routinely, as they are a common harbor of allergens.
    • Make sure to clean behind and under furniture.
  • Watch your residence’s moisture levels. Increased humidity levels can also result in more severe allergies. Humidity enables mold growth and dust mites. Adding a dehumidifier to your HVAC system keeps moisture levels under control and your indoor air quality much fresher.

What is the Best Furnace Filter for Allergies?

Typically, HEPA filters are the best if you or someone in your household struggles with allergies. HEPA filters are rated to remove 99.97 to 99.99% of particles, like 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 take pollutants from the air. Because of their high-efficiency filtration materials, HEPA filters are thick and can limit airflow. It’s helpful to touch base with Bob Brown Service Experts to make sure your heating and cooling system can perform right with these high efficiency filters.

Can Dusty Filters or Air Ducts Make Me Sick?

Old filters can hold on to particles and allow poor quality air to recirculate. The same goes for dusty air ducts. If you inhale these particles it can produce sneezing, coughing or other asthma-related problems, depending on your sensitivity.

It’s beneficial to swap out your HVAC filter every 30-60 days, but here are some signs you could need to more frequently:

  • It’s taking longer for your system to cool or heat your residence.
  • You notice more dust in your home.
  • Heating and cooling costs are going up with no apparent reason.
  • Your allergies are acting up.
  • Clues your air ducts require cleaning include:

  • The metal is sitting 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 starting.
  • Your home is always dusty, despite continuous cleaning.
