FAQs

  • Humidifiers and Dehumidifier Services in New Hampshire

    How Humidifiers and Dehumidifiers Work

    Whole home humidity control systems should not be confused with other equipment like air conditioners or air filtration systems. Here’s a quick breakdown of the two types of systems available to homeowners:

    • Humidifiers: Whole home humidifiers are dedicated systems that add humidity (moisture) to the air through the use of existing ductwork from your furnace, or by use of a ductless steam system. You’ll want a humidifier if you find yourself cranking your heating system up no matter what the thermostat reads, or deal with the aggravation of dry/itchy skin and static electricity. Low humidity can also cause damage to sensitive wood furniture and musical instruments.
    • Dehumidifiers: While it’s true that air conditioners do remove humidity from your indoor air as an essential part of keeping you comfortable, they are not dedicated air drying systems. Likewise, while a dehumidifier acts similar to an air conditioning system by passing air over a cold refrigerant coil to capture condensation; it is designed to handle moisture removal much more effectively. If you deal with mold build-up, feelings of being muggy or clammy even when the air is cool, or just general discomfort while indoors, a whole home dehumidifier may be right for you.

    Regardless of what you need, both devices can be controlled by their own type of specialized control called a humidistat. This allows you to read the indoor humidity and automatically set it to the level you find most comfortable, just like your thermostat.

  • Why Do New Hampshire Homes Need Humidifiers or Dehumidifiers?

    Depending on your surroundings (such as elevation, nearby water sources, sunlight exposure, etc.), your seasonal humidity levels can fluctuate, and it may not always be when you expect. Humidity in New Hampshire tends to drop in the colder months, with spikes of high humidity in the summer, however, if you already have an air conditioning system such as ductless or central AC, your unit actually removes moisture from the air when cooling. In fact, many homes may experience high humidity indoors during the winter when their heat is running and windows and doors are closed.

    This can be due to things such as poor ventilation when taking showers or cooking or using appliances such as the dryer and dishwasher. Cold surfaces such as windows will tend to sweat from the inside, and you may even notice mold build up in areas. This is all an indication that you have a high indoor humidity problem.

    On the other hand, if you frequently deal with dry skin, static electricity, and generally feeling cold no matter how high you set your thermostat, you likely have an absence of moisture in the air and could benefit from a humidifier.

Good morning. I recently had service done at my house. I would just like to say a few words about the two electricians who came for that service call. Bryce was the best! They were polite and professional. They diagnosed the issue using a great deal of skill and expertise. They kept me informed every step of the way, and I am more than satisfied with my results! I really have nothing but wonderful things to say about you and your company. I will only use you in the future, and will heartily recommend your company to others. Thank you so much and have a great day!

William was exceptional and knowledgeable. We are in the process of selling our home and purchasing a new home. He walked us through the issues with our current plumbing problem. He also provided us with invaluable information on our new home which has a septic system. I would definitely recommend William to anyone looking for plumbing needs.

called Heritage Home Services expecting a repair and maybe a mild headache. Instead, they showed up on time, knew exactly what they were doing, and somehow made home maintenance feel less painful than assembling IKEA furniture. The technician was professional, friendly, and explained everything in a way that didn’t require an engineering degree. The work was done quickly, cleanly, and without any surprise drama—which, if you’re a homeowner, you know is basically a miracle. My house is happier, my stress level is lower, and I’m pretty sure even my thermostat is smiling. If home service companies had a Hall of Fame, Heritage Home Services would have a plaque near the entrance. Highly recommend them to anyone who enjoys competent service, fair treatment, and not having to watch YouTube tutorials to fix everything themselves.

Ryan O’Connor of Heritage Home Service did a marvelous job installing a smart leak detector on my cold water line. It required some “creative” piping. When he was done, the site was immaculate.
