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 Home Performance shows its expertise from start to finish. Evergreen did three house projects in winter/spring/summer 2020 for me, attic insulation, crawl space under a porch insulation, and basement foam/vapor barrier. From my initial discussion with Bryan, I understood the reasons for choosing different types of insulation, the associated costs, and time estimates. Evergreen scheduled in advance, came when they said they would, and the crews were highly professional in their work and demeanor.

The Evergreen team was amazing from initial assessment and planning to the crew that came to complete the work. Our basement encapsulation is the best money we've spent on our house by far. The work was thorough and high quality. And what a wonderful group of people to work with. I highly recommend Evergreen!

Martha Bracy

Evergreen has a professional and reliable team of people who do excellent work. If you want the best of the best in the area, select Evergreen to accomplish your insulation needs.

The Evergreen Team did a fabulous job, well exceeding our expectations, In just over a week they transformed our very drafty, noisy 213 year old house into a snug, draft-free, quiet haven with warm floors! The team was prompt, did everything they said they'd do and more. We are thrilled!

Awesome company. It was a few years ago that they did the audit and then we commissioned them to do the work. We subsequently sold our house and moved to South Africa, but their level of service and expertise will live on.

Odette Brown

Evergreen did a fantastic job replacing 28 windows in our house. They were friendly, courteous, and very detail oriented. Brian did a great job planning, estimating and executing the project. Our energy use has dropped significantly since the work was done.

From beginning to end – that is from the moment Justin McEdward stepped into our home to assess our energy conservation needs until the crew left – the Evergreen Home Performance process went absolutely smoothly. Justin made a thorough inspection and took pictures with an infrared camera. His proposal described the scope of work in detail, and he explained what we could expect the proposed work to accomplish. Our proposal was forthcoming within a couple of days, and Justin was available to discuss it and answer questions.

Great team!

We had Evergreen come out to our tiny old (100+ year old) house to see what they would recommend for decreasing our carbon footprint, saving money, and increasing our comfort in the cold season. Richard and Bryan were great to work with, patiently answering our many questions and walking us through multiple options. We could only afford to tackle a few areas this year; we ended up replacing some windows and having them weatherize the entire house.

We had Evergreen energy do blow-in cellulose. I was very happy with the result. They tested with blower-door before and after. House is now MUCH warmer. Also, in the time since when I've had to open walls for various access, I've been impressed with how they got the insulation packed in everywhere. I'd use them again.

Evergreen was so helpful in securing us Efficiency Maine funding for a big attic insulation project early this winter. They did all of the paperwork, and totally guided us through a vermiculite removal process that included a payment from a trust for the procedure. I could instantly feel the second floor being so much warmer than before. The boiler does not kick on nearly as frequently since they completed the job. It was worth every penny! Brian Robinson was so thorough throughout the whole process including a full walk through after the job had been completed.

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.

Thanks Evergreen Home Performance for helping to make our home more efficient. Many thanks as well to Bryan for the initial walk through and recommendations to make our home more efficient and to Dave, Roland, and Jacob for a job that was done professionally and courteous.  We were amazed at the level of efficiency and everyday they made sure to protect our floors, carpets, and furniture. We had daily discussions with Dave about progress and what was being done and where they were at in the project.

Carol Fink

I have always been impressed by the high level of service, quality of work, and excellent follow-through provided by Evergreen Home Performance in the three projects that they completed at the Wells Reserve at Laudholm over the past several years.

I had gotten estimates from several other companies, but Evergreen was in another league entirely with their professionalism. If you want the job done correctly, I couldn't recommend this company enough.
