New Hampshire residents can experience a large portion of the year indoors with windows closed due to weather. Especially during winter, where things like colds, stuffy noses, and watery eyes are just a fact of life. But have you ever wondered what causes these issues in the first place? It may come as a surprise to you that on average your home’s indoor air quality can be two to five times worse than outdoors. This is even more concerning when you discover that as a whole, Americans spend 84% of their time indoors, whether it be at home or in an office according to the EPA.

This is why Heritage Home Service has been educating our customers on indoor air quality (IAQ) for protecting you and your family’s health year-round.

Indoor Air Quality Services in New Hampshire

A home’s indoor air quality is affected by numerous factors, but one major contributor is your home’s air exchange rate or ability to circulate clean air into the home. On average, American homes exchange the air four to five times per hour with windows open, and only one to two times per hour with the windows closed. This can be even less depending on how well your home’s ventilation was designed when it was built. With many of our homes built well before the turn of the century, good air ventilation was not a common consideration.

To compound this, living in the Northeast means many months out of the year require us to keep windows and doors closed to conserve energy. The building up of airborne contaminants indoors are what can lead to things such as the increased likelihood of colds, seasonal allergies, asthma irritation, and more. Having clean indoor air can help alleviate these symptoms, especially for vulnerable family members.

Good indoor air quality is often referred to as an “intangible”, something you just have to experience to understand the benefits of. However, there are true measurable impacts on how a good IAQ system can improve the lives of those living in your home.

By installing the proper IAQ device, you can alleviate or virtually eliminate the following:

  • Seasonal allergies
  • Asthma symptoms
  • Cold/flu virus exposure
  • Mold formation
  • Dry air

And much more

The most important thing is having the knowledge to understand your current air quality and what the correct treatment is. By choosing Heritage, our IAQ experts will go over your needs and help you customize a solution that’s perfect for your home.

Heritage offers the following services:

  • Whole home air filtration (ERV or HRV systems)
  • UV light purification
  • Electrostatic air purification
  • Ionic air purification
  • Whole home humidification
  • Whole home dehumidification

Our fully licensed team of HVAC professionals can help replace or service any of your existing whole home IAQ equipment as well.

The first step is to track your air quality conditions and how they affect you. Off-the-shelf monitors are available which can detect certain pollutants such as carbon dioxide levels or off-gassing from formaldehyde. Another, more obvious way is to keep a record of how you feel in your home during the months when windows and doors need to be closed. Feelings of excessive drowsiness, aggravated asthma, headaches, and frequent colds or illness can all be signs of poor indoor air quality.

Consulting an IAQ professional about these experiences can help identify a system that can help alleviate these problems. Portable filtration and dehumidification devices are also available to homeowners and will often be sufficient for smaller spaces, but their applications are limited and typically do not exchange air quick enough to cover an entire home.
