How Your HVAC System Can Affect Allergies

In the South, the Spring can be the worst time of year for many. Pollen levels are at a all time high, flowers are blooming, dust is building and many other allergen triggers. When we are inside, we tend to feel the safest from them, but your HVAC system can come into play. So, how can your HVAC system affect allergies?

Filters

The first thought that may come to mind is the filters, which is absolutely correct. Dirty filters invite dust and other particles in your home. They should be changed every 1-3 months. Please read more about changing the filters in the “Air” section here. If you do not know how to change the filter, ask the technician the next time they visit. They can also give advice on which filters to choose, when to change them, and what is the correct size for your system(s). Of course better quality filters will do a better job at keeping out unnecessary and allergy-triggering particles. We have found that filters of MERV 11-13 or HEPA are best. MERV stands for Minimum Efficiency Reporting Value which is term to measure the effectiveness of a filter. HEPA stands for High-Efficiency Particulate Absorbing which is a more expensive kind of filter and does not filter gas.

Cleaning

Spring cleaning is a common phrase and practice; rightfully so. Cleaning your space can help lessen allergy symptoms and particles from getting into your body, system(s), and filters. Also, we recommend getting your system cleaned before or during this time of year to prevent build-up and lengthen your system’s lifespan.

Keeping the system clean can also be helped with an air purifier or air scrubber.

Build-Up

Speaking of build-up, as the weather gets warmer, the humidity levels rise. High humidity can lead to mildew build-up which can worsen allergy symptoms and other issues. Consider a dehumidifier or humidity control to your system. This is an easy way to change how your HVAC system can affect allergies. These implications control how much humidity stays in the space by taking in the humidity and wrapping them through the cold evaporator coils. This actions takes the liquid from the humidity and turn it into condensations which drips into drain pan then thorough the drain pipe outside.
