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.

FAQs

  • Indoor Air Quality Services in New Hampshire

    Why Does Indoor Air Quality Matter 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.

  • How Indoor Air Quality Impacts a Home

    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!

    Th 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.

  • New Hampshire Indoor Air Quality Services

    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
    • Duct Cleaning

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

  • What Can Homeowners Do to Improve Indoor Air Quality?

    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.

If You’re Sick And Tired of Being Sick And Tired, Just Call Heritage

Excellent indoor air quality is really something you have to experience in order to understand the huge difference it can make in your daily life. When so much more of our time is spent indoors, maintaining the health of you and your family is important.

Kyle came by and checked out our AC units l, did a great job very professional and knowledgeable. He even looked at my boiler set up to see about replacing it and messaged a project manager to see about coming out the same day to do a quote. Will be using these folks from now on!

This was our first time using Heritage and it was a great experience. We got an appointment promptly and Bryce and his apprentice arrived right on time. Bryce was a true professional throughout the process. He was troubleshooting a complex whole-house electrical issue for us: he approached it logically, fixed a number of things along the way, kept us updated throughout, explained the issues and our options clearly, and ultimately solved the problem. We will definitely use Heritage again.

Frequently Asked Questions

  • Why is indoor air quality important for New Hampshire homeowners?

    New Hampshire homes are sealed tightly for energy efficiency during the long heating season, which can trap pollutants like dust, pet dander, mold spores, and volatile organic compounds inside. Poor indoor air quality can aggravate allergies, asthma, and other respiratory conditions, making proper air filtration and ventilation essential.

  • What indoor air quality solutions does Heritage offer?

    Heritage offers a range of solutions including whole-home air purifiers, HEPA filtration systems, UV germicidal lights, humidifiers, dehumidifiers, and energy recovery ventilators. We assess your specific air quality concerns and recommend the best combination of products for your home.

  • How do I know if my home has poor indoor air quality?

    Signs of poor indoor air quality include persistent allergy symptoms, musty or stale odors, excessive dust buildup, condensation on windows, and family members frequently experiencing headaches or respiratory issues. Heritage can perform an assessment to identify the sources and recommend targeted solutions.

  • Can a whole-home air purifier be added to my existing HVAC system?

    Yes, most whole-home air purifiers and UV germicidal lights are designed to integrate directly into your existing HVAC ductwork. Heritage installs these systems so they work seamlessly with your furnace or air handler to clean the air every time your system runs.

  • How much does an indoor air quality system cost?

    Costs vary depending on the type of system, from a basic air purifier to a comprehensive solution with filtration, humidity control, and ventilation. Contact Heritage for a home evaluation and a personalized recommendation with transparent pricing.
