How Important Is Ventilation for a Healthy Home?

Back to Blog

Not only are we all waiting out a pandemic here in Maine, but the snow, ice, and brief window of daylight are forcing us all to wait it out indoors! Does this have you thinking more about your home, and the systems you use to keep your family safe, comfortable, and healthy?

Those concerned about how all this time indoors might be affecting their health may also be wondering what role ventilation plays, or should play, in a home that is considered healthy. And the answer is, an extremely important one!

Your Home Is A Trap for Pollutants

In order to understand why ventilation is important, we need to also understand how and why a home may become unhealthy in the first place. Homes can be a source of contaminants that decrease your indoor air quality (IAQ). They include:

  • Volatile organic compounds from synthetic components of furnishings (furniture, carpets, curtains)

  • Pet dander

  • Cleaning chemicals

  • Carbon monoxide and other combustion gasses

  • Mold & mildew

  • Radon (from the basement)

  • Dust

  • Wood smoke (from wood-burning appliances)

Contaminants from the outside can make their way in, too, through open windows/doors, or through the small holes and gaps that are hidden throughout the attic, basement, and around doors and windows. 

Outdoor pollutants come from a variety of sources, like:

  • Pollen

  • Street dust 

  • Car & industrial air pollution

  • Wood smoke

Once these contaminants enter the air in your home, the air intake of your heating and cooling system will recirculate them over and over again unless they are actively removed. This makes them much more likely to affect the health of you and your loved ones. 

Poor Ventilation & Your Health

Indoor air that remains contaminated can create the symptoms of seasonal illnesses, such as:

  • Coughing

  • Sneezing

  • Dry and itchy eyes

  • Sinus irritation

  • Headaches

  • Brain fog

Poor IAQ can also be concerning for those with respiratory illnesses or sensitivities, like asthma, as it is likely to exacerbate these conditions.  

Cleaning The Air 

The first thing to do when trying to improve your IAQ is to seal up your home and properly insulate it, so that you can control how many contaminants are coming in. An energy audit from Evergreen Home Performance will uncover all of the areas in need of sealing and insulating. You may also want to encapsulate your basement or crawlspace to ensure that no excess moisture is infiltrating into your home creating mold-growth conditions. 

The air filter associated with your heating and cooling system can capture some of the contaminants that enter your breathing air, but as filters clog, they become more taxing for your furnace or air conditioner. For many Maine homes, especially homes that don’t utilize central ductwork for their heating and cooling, added ventilation and filtration may be required. 

Many homes already have enough ventilation, like bathroom fans, laundry fans, and oven range hood fans. However, these fans must exhaust to the outdoors if they are to provide any benefit to the quality of your air. Unfortunately, many of these fans dump their air into the attic, only to re-circulate again.  

Whole Home Ventilation

Depending on your needs and the medical sensitivities of your family members, whole-home ventilation can offer the maximum benefits of ventilation, all year long. Whole-home ventilation systems like ERVs (energy recovery ventilators) and HRVs (heat recovery ventilators) exchange the stale indoor air for fresher outdoor air, removing contaminants from your indoor space. And some of these whole-home ventilators can even pre-condition the air for your heating and cooling system, leading to a reduction in wear and tear!

Experience the Benefits of Proper Ventilation

Sure, ventilation is essential to living in a healthy home. However, there are many other benefits you can experience when you upgrade your ventilation system, insulate, and air seal your home, such as: 

  • Stable indoor temperatures throughout the home

  • Ideal humidity levels all year

  • Reduced indoor odors

  • Reduced energy use and costs

Evergreen did a fantastic job insulating our 1930's home. The onsite team was professional, clean, and really just a joy to interact with throughout the process. A blower test at the end showed a significant decrease in air leakage. I highly recommend Evergreen.

Very easy process, start to finish.  Friendly, professional, and really know their stuff.  They made some improvements to our condo and we were very happy with how it played out.  Would definitely recommend them.

Our basement was the eyesore of the house. I wanted to make improvements, but first needed to make structural, insulating and moisture mitigation improvements. Evergreen was professional and competent in taking on a complex project of not only encapsulation and insulation of basement and crawlspace, but completed needed improvements to the structural integrity of the wood floor platform above a crawlspace and brought in a concrete contractor to pour where there was once a rotting, tiered wood platform - replacing that area with a more functional and tight tiered concrete area.

Led by Brian Robinson, the Evergreen Home Performance team just completed an insulation refit at my home. It was truly a great experience from start to finish, a period of time that was a fraction of the time that I originally anticipated due to the team's unbelievable work habits and professional knowledge of their tasks. As impressive were the communication skills and friendliness of each and every member of the team.

Very Satisfied with the work performed by Evergreen. Professional employees, high quality work done in a timely manner. My sales rep was Justin, and he was phenomenal During the initial walk around my house, he gave me great ideas for how to improve the efficiency of our home. We will consult with Evergreen for our future home projects.

They were highly recommended. I found them to be very knowledgeable and so helpful, with practical ideas. Despite my not living within their service area, they were generous with their knowledge, describing the usual solutions to correct leaks in my basement, and what the result is likely to be by following path A, B or C, and why. I was discouraged. Talking with Evergreen helped me see that my basement problems are far from insurmountable and really, fairly common in 100-year old homes. There are proven solutions.

The Evergreen crew from initial inception to installation were professional, on time, and left our place spotless. The end result was exceptional.

The team members were very professional, worked very hard, paid very close attention to detail and cleaned up meticulously every day. I really appreciated the care they took knowing the smallest details were going to make a big difference to our heating bills. Thank you!

I cant say enough about this company and the benefits that it created for our family. They are very professional and have effectively re-insulated our home. The heating bill proves the point.

We absolutely loved our experience with Evergreen. The team was incredibly kind, professional and great to work with. We're very impressed with the quality of work of the Evergreen team and how easy they made everything! Our house had barely any insulation ahead of this project and the results are amazing. Insulating the attic, walls and basement with Evergreen allowed us to tear a 50-year-old furnace, ductwork and oil tank out of the basement and now heat the home with new heat pumps. Evergreen also added 100 sq ft of clean, new storage space to the attic!

Last week, my oil company asked if we were using some other kind of fuel because our usage was so much less than they had expected We are very happy with the results; the house is much more comfortable

I would recommend Evergreen wholeheartedly because of their professionalism, their follow through, and thoughtful project planning.

Jennifer A

Evergreen is a terrific company to deal with. Polite and efficient crews, meeting deadlines and major reduction in our heat bills. They corrected a lot of issues we suffered from doing work with a shoddy building contractor. We would recommend them to anyone.

Mary Carey

We had a fantastic experience working with Evergreen to insulate our roof this winter. Everyone was extremely friendly throughout the process - the crew at our home worked hard, were approachable with questions, and the team leader even showed me around the project to point out specific areas they were working to improve.
