How to Fight Fall Allergies Indoors

When it comes to seasonal allergies, most people immediately think of spring. However, fall allergies affect a lot of people, and the cooler temperatures can reduce the effectiveness of your immune system, which in turn enhances the effects of allergies. To help keep our customers, neighbors and friends healthy and safe, we put together this fall allergy survival guide. 

Causes of Fall Allergies

Ragweed is the main culprit when it comes to fall allergies, and most people who suffer from spring allergies also suffer from an allergy to ragweed. Ragweed can travel for hundreds of miles through wind currents and can cause eye and lung irritation, which make going through your daily life absolutely miserable.

Mold is another air pollutant that increases as the weather begins to cool. When the temperature cools, humid clouds become damper and lead to conditions that are perfect for hosting mold. Another important factor to note is that as leaves fall and pile up, they restrict airflow and hold water, which can lead to mold growth around your home. So, if your home is surrounded by trees, it’s important that you take note of possible mold growth. 

Thankfully, there are some easy precautions to take that will help keep you healthy and manage your allergy symptoms this fall. 

Invest in Indoor Air Quality

One of the most effective ways to reduce the number of particles in your home is to invest in indoor air quality products. Air purifiers are perfect for folk who suffer from severe allergies and asthma because they cycle air through and catch the pollutants and particles in the air. 

HVAC Maintenance to Reduce Fall Allergies

You may have heard that a tune up to your HVAC unit improves performance and energy efficiency, but it also can have tremendous benefits on anyone who is suffering from fall allergies

Your heating system collects dust and other allergen particles from the air and passes them throughout your home. As the air continues to circulate, this dust and other debris move around and become trapped by the filter. As the excess dust particles and debris clog up your filter, it is unable to deliver the allergen-fighting power you need. A professional tune up cleans out your heating system so that fresher air circulates throughout your home. 

A HVAC tune up also allows for our technicians to assess your system to determine other issues that could be triggering allergy symptoms. These issues might include duct leaks that could be allowing airborne contaminants such as pollen, dust mites and dander into the duct system and the air you breathe. 

What You Can Check Yourself

There are also several things you can do on your own to boost your home’s indoor air quality as well as enhance your HVAC’s efficiency.

  • Clean your HVAC unit: Take a little time to clean the dust and dirt off of your outdoor HVAC. After a long summer, it’s likely that your outdoor AC unit is caked with dirt. 
  • Clean your ducts: If there is dust and dirt in your home and on your HVAC, it’s likely in your ductwork as well. Unfortunately, this is not a job you can do yourself. To clean and seal your ductwork, you must employ professional help.
  • Check your filters: As seasons change, it is important that you take a look at your filters and ensure that they are new. Newer filters will be better at catching the pollutants in your home’s air and ensuring they do not continue to cycle through the air.

Indoor Air Quality Products That Will Reduce Fall Allergens

Indoor air quality products help your home’s heating and air conditioning systems circulate cleaner air with fewer contaminants in your living spaces. While it’s inevitable that some outdoor allergens will make their way into your home, indoor air quality products work to pull them out of your air supply to minimize any allergy symptoms. 

Air cleaners

Install air cleaners with your heating system so that all conditioned air passes through for contaminant removal. They use advanced filtration and other processes (depending on the type of air cleaner) to eliminate contaminants up to 99.9 percent.

UV lights

UV lights destroy microorganisms inside of your HVAC unit. The lights are usually installed in your ductwork or near the AC coil to destroy mold, bacteria, fungi, mildew, mold and other viruses in your system. This not only stops the growth of mold and mildew inside your system, but also neutralizes spores circulating through your home’s air from outdoors. 


A whole house dehumidifier monitors and controls the amount of humidity in the air to keep you healthy and comfortable. This device extracts any excess moisture, reduces the stress on the AC system and prevents mold growth, which is a major allergen. 

High-efficiency filters

While a filter’s main purpose is to prevent dirt and dust accumulation inside the system to protect components, they also are able to remove contaminants from your air supply to reduce indoor allergens. When looking for a filter, you will want one with a MERV rating of 8 to 12 for maximum allergen control in your home.
