Why Your HVAC Unit Matters For Your Allergies

by Kaitlin KrullJune 19, 2018

If you suffer from allergies, you probably already know that any number of environmental factors can contribute to allergic reactions and flare-ups. While there are generally more allergens floating around outside your home, they can also be present indoors in the form of dust, dander, mold, and other microscopic airborne substances. Keeping your home as allergen-free as possible is therefore essential if you have allergies. Thankfully, modern HVAC systems contain several features that help to filter and purify the air inside your home so you don’t have to worry. These are just a few of the reasons why your HVAC unit matters for your allergies.

Air Purification

Allergies from airborne particles are extremely common, with nearly 50 million Americans suffering from nasal allergies. Most nasal allergy sufferers react to dust, pet dander, pollen, and mold spores, so keeping their homes free from all of these can be a complicated process.

However, most HVAC units are now equipped with filters and air purification systems that work together to eliminate the presence of allergens in the air inside a home. From filters installed in the air intakes and furnace systems of your HVAC unit to advanced ductwork that removes particles from the air before it enters the rooms of your home, there are several options to choose from at a variety of price points.

By speaking with an HVAC professional about your options and costs, you can decide whether you want to incorporate a whole-house air purifying system into your existing unit or opt for several standalone units to improve the air quality in your home.

Consistent Humidity Levels

Because some allergies can be exacerbated by inconsistent humidity levels, keeping your home properly humidified will help you to feel as healthy as possible and prevent flare-ups. If you live in a hot area and need to run your air conditioning unit frequently, the air inside your home may become too dry and cause your allergies to flare up. Likewise, if your home is too humid, mold and mildew can build up and trigger allergies (as well as being detrimental to everyone’s health).

While the optimum humidity for your home depends on a variety of factors, including the outdoor temperature, you should generally aim for a humidity level of between 35 and 50% according to the experts at hvac.com. Newer HVAC systems with more advanced functions often come equipped with built-in humidifiers and can regulate humidity levels automatically or to your exact specifications. If your HVAC unit does not have these capabilities, you can still control the humidity in your home with a standalone humidifier or dehumidifier depending on your needs and preferences.

How to Make the Most of Your HVAC Unit

Many allergy sufferers feel that being indoors is often better for their bodies than being outside. To keep the environment inside your home as healthy as possible, there are several things you can do to improve the air purification and humidity components of your HVAC system. These include:

  • Regularly cleaning your ducts and filters
  • Having your unit serviced annually
  • Choosing high-quality filters for your HVAC unit and replacing them seasonally (or referring to instructions as they vary depending on the type of filter you choose to use)
  • If necessary, upgrading to a system that has built-in purification and air handling systems – otherwise, using your existing unit in conjunction with purifiers and humidifiers to keep allergens at bay

After the first few months, you will get the hang of your new HVAC maintenance routine and find the air quality in your home to be better than ever. Most of these jobs are simple enough to complete yourself, but you can always call your local HVAC professional for guidance or help. Although the costs of new and upgraded HVAC units can seem daunting, remember that you deserve to feel healthy in your home and therefore you shouldn’t feel bad about making yourself a priority by choosing the best HVAC unit and accessories for you.
