Improve Indoor Air Quality with HVAC

Updated: May 9, 2022

Indoor air quality is on top of mind for many homeowners around the U.S. and around the world right now. With airborne particulates being particularly concerning these days, along with allergens in the air, it’s important that your home be as comfortable and safe as possible.

HVAC can be used to increase energy efficient heating and air conditioning - as well as provide air filtration.

Even if you do not have a functioning filtration system in your ventilation shafts, there are simple solutions for improving indoor air quality with your HVAC system.

How Your HVAC System Effects Indoor Air Quality

There are a few ways that your heating, ventilation, and air conditioning system helps to improve your indoor air quality.

Air conditioning

Not only does air conditioning recirculate air throughout your home, but it also pulls in external air. Because your system filters everything from particulates created by local fires or additional moisture caused by fog, this system is a vital part of your indoor air quality regulation.


Home ventilation consists of a system of exhaust and intake vents that creates a healthy airflow throughout your home. Bringing in external air and venting recycled, indoor air is a vital part of creating a healthy flow. Blocking any internal vents can reduce air flow, causing air to stagnate and reducing your indoor air quality.

Air filters

Many homeowners have added additional air filters to their HVAC systems. Any air filtration will improve your indoor air quality, and more filters can help to block specific particulates, such as allergens, from entering your home.

Your entire HVAC system works together to improve your indoor air quality. Every element of the system serves a purpose. If you plan to update your HVAC system, be sure to consult with the experts here at SF Green Construction. We are here to talk with you about your specific HVAC need - and to provide you with the best, most cost-effective system available.

Four Solutions for Improving Indoor Air Quality

As established above, your indoor air quality is dependent on your HVAC system and the structural elements of your home which contribute to ventilation. Here are additional solutions to help you improve indoor air quality and increase your comfort when you are at home.

1. Get your HVAC system cleaned and maintained

Your HVAC system moves air throughout the house. If a portion of it is faulty, installed incorrectly, or growing mold spores, then your indoor air quality will suffer. The best way to prevent HVAC issues is to perform regular cleaning and maintenance on your existing system - and any new HVAC units that you have installed.

2. Upgrade your system to ensure the filtration fits your need

Many systems allow for upgraded filtration, additional air filters, HEPA filters, and more. Get in touch with our team of experts to clarify the type of filtration you need and we will work with you to build the HVAC system that fits your needs.

3. Regularly clean or change your air filters

One common HVAC issue that many homeowners encounter is dirty air filters. Your filters are supposed to get dirty, that is their function. But once they are clogged with dirt and particulates, they stop working. Prevent this by regularly cleaning or changing your air filters.

4. Reduce mold-producing condensation

You can support your HVAC system by installing double pane windows and doors. If you have single panes, condensation will form almost daily due to temperature differentials, which can lead to the production of mold spores in your home. Installation of double panes can help to prevent this issue.
