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

If you are looking to increase the IAQ of your home here in Southern and Mid Coast Maine, schedule an energy audit with the team at Evergreen Home Performance. We can put together a plan to get your home (and your family) back to health! We’ll also explain to you how Maine Efficiency Maine rebate and financing programs help make your project affordable.

Evergreen listened and produced a thoughtful evaluation, proposal and comprehensive plan for our attic and basement. They exhibited excellent workmanship, teamwork, and came back as planned after the completion of the job to test the outcomes. Their overall performance as insulation and home improvement contractors is truly outstanding and we highly recommend them.

I never leave reviews, but had a great experience with Evergreen and wanted to spread the word! In short, we worked with them to insulate our roof this winter and have noticed surprising immediate results. The constant ice dams I have wrestled with are completely gone, and the home is noticeably more comfortable. It's a little too early to tell if our oil bill is going to reduce, but I imagine we will see an impact there as well.

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 job installing windows and insulation.

I was extremely pleased with the professionalism and quality of service that I received from the Evergreen team. I met Richard to discuss options for insulation. I knew immediately that I wanted to do business with them because he did not try to over-sell extra services that I did not need. Dave was the project manager. He was not only kind, but very respectful of my home. I would highly recommend this company.

Evergreen did an amazing job insulating our historic home. Their professional staff worked hard to ensure the tough areas in the attic were covered, and clearly communicated their progress. We are seeing the results with our discounted heating bills. Thank you, Evergreen!

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.

We are so pleased with the work the team from Evergreen Home Performance did in our home. The project included encapsulation of our basement with a reinforced vapor barrier, installation of a sump pump, spray foam insulation on the walls and insulation of the heating duct work. Everyone at Evergreen was friendly and professional. The project was completed on time and in budget. Our home is much cozier and warmer since the project was completed.

I am very pleased with my experience with Evergreen Home Performance. I met several times with Richard Burbank and he was very detailed in his explanations to all of my questions. He provided me with several options for improving the insulation to our home. The team of installers were very professional and respectful of our home. They did a great job of cleaning up every day after the days work and they were also very responsive to all my questions as well as we collaborated to get our home better insulated. It was a pleasure to work with Richard and…

We had Evergreen Home Performance of Rockland come in to make our home more energy efficient, and what a TOP notch crew. Brian and his crew did an amazing job from start to finish. Very knowledgeable and professional. We would Definitely highly recommend this crew to anyone who is looking for energy efficiency in their home with a company that truly is an expert and knows how to do a quality job and truly cares about their customer.

Evergreen did everything they said they would and more. I actually don't mind going into the basement now since they sealed it. The air quality in the house is noticeably better and it's warmer in the winter. We can even store clothing down there where before, whatever was in there would mildew. Even the spider population declined! I used to vacuum so many of them from the corners of the ceilings in the house. Not any more!

The crew members from Evergreen Home Performance each made sure to greet us every day, while maintaining their distance in this time of the pandemic. Their work took a total of nine days, spread over three weeks. Even though they were working in multiple rooms of our house, as well as the basement and attic, they were unobtrusive and always cleaned up after themselves every day. The on-sight manager kept us informed of their daily schedule so we'd know which parts of the house they'd be working on.

We just finished a large project of air sealing and reinsulating our 1890s basement and attic which had been completely renovated 8 years ago but still felt cold and lacked proper energy assessment and corrections. We met with Justin in December and were very impressed with his knowledge, professionalism and communication skills and knew Evergreen was who we wanted to work with. Dave was our on hands project manager and was excellent. The office staff has been quick to respond and helpful as well when needed.
