Do HVAC Systems Help Alleviate Allergies?

You may be surprised to learn that HVAC systems play a more significant role in alleviating asthma and allergy symptoms than you might think.

For homeowners like yourself, an investment into additional HVAC accessories can help improve your home's air quality even more. With easy options available for optimizing the system, there are many benefits of investing in this type of technology.
 
Here are five ways to alleviate allergies with your HVAC system

1. Put a stop to indoor allergens
Indoor air pollution is a common source of allergies in the home. The most prevalent allergens found inside include pet dander, mold, dust mites, pollen, and cockroach droppings. Your HVAC system's filters can trap these substances when they become airborne but don't prevent them from affecting you, causing allergic reactions or asthma attacks. What's more, your unit may also harbor mildew and mold, which will end up in your indoor air during cooling cycles, so it's essential to maintain an annual service agreement for someone with allergies or sensitive lungs, such as those who suffer from asthma complications because this could make breathing easier!

2. Choose the best air filter for your home
A good air filter is essential for allergy sufferers, and the MERV rating can be used as a measure of effectiveness. A higher number on this scale signifies greater efficiency in trapping small particles which can trigger allergies. To find out your needs, an expert should help you make the right decisions when it comes to purchasing quality filters that will benefit you more than anything else. Studies show that particles are more easily removed when HEPA filters have a rating of 17-20. However, these high-efficiency air filtering can put stress on an HVAC system. As such, it is highly recommended to consult with your technician for help in selecting the proper filtration for your unit.

3. Air purifiers can help
The best way to stay allergy-free is by having a clean home. But if you have allergies and still suffer from them no matter what the season? Air purifiers are your solution! HEPA filters trap allergens in the air that you can't even clean up with an HVAC system alone. If someone in your family has severe asthma or allergies, this might be for you because it improves the quality of life throughout our whole house.

4. Combat humidity
Humidity levels can be a significant trigger for many people living with asthma, especially during the summer. Luckily there are ways to alleviate this and create an environment within your home that is safe and healthy for everyone, including humidifiers installed throughout the house or whole-home dehumidifier installation, which will help keep those humidity levels under control.

5. Use the latest technology to kill allergens
Combating humidity levels and preventing allergens may be the basics of home upkeep, but what if you could kill bacteria, mold, and other allergy triggers before they have a chance to spread throughout your space? UV lamps that are installed in conjunction with an HVAC system sterilize both coil as well as air. While it's a relatively expensive technology to implement for homes that suffer from poor indoor quality issues (especially those on budgets), this is perfect for households with ongoing tension about cleanliness or allergies.


The ideal types of upgrades for an aging heating/cooling unit are routine tune-ups that maintain optimal performance. Ensuring all parts such as coils have been cleaned will ensure maximum efficiency while reducing dust buildup, which could trigger allergies or asthma symptoms.
One of the best and most cost-effective ways to optimize your HVAC system is scheduled annual maintenance service. This should include having your air filters changed, as well as changing or rebuilding dirty coil fins to improve airflow and keep the system running efficiently.
