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.

When my AC quit suddenly, Heritage came in a timely fashion and did an excellent job. The four gentlemen who helped me were professional and knowledgeable. Joe diagnosed the problem and was very thorough in explaining the cost of repair versus replacement. Bobby, Harrison and the electrician Liam did the replacement and were wonderful to work with. They explained the process carefully, answered all my questions and completed the job efficiently and quickly. I would certainly call the company again for any HVAC, plumbing or electrical needs. Thanks Heritage!

First time using Heritage, as two other plumbers I’ve used in the past gave me long lead times. Heritage answered my call personally, and scheduled me same day-amazing considering it was a Saturday! I had a leaking outdoor spigot, and given the drought, waiting a week to fix it was out of the question. The technician sent out, James Shallow, could not have been more professional, knowledgeable and personable. He showed up on time, did the job seamlessly and without issue. He spent time educating us as to how to avoid this problem in the future, and it was a genuinely pleasant experience. I will most definitely use & recommend Heritage again (request Jimmy).

Alex came to fix a water main leak at my home which was pre-manufactured in the late eighties. He found and fixed the leak quickly. After the job was complete I spoke with him about the cause because this is the third time in a year with a leak. He spent the time with me explaining the material used for piping in my place and checked the water pressure. The pressure was on the high end and we both concluded between pressure spikes and old plastic pipes. I asked for an estimate to replace all the pipes. He was able to give me an estimate on the spot and found financing with very reasonable terms. Two days later Heritage Home Services was here with two trucks and completely changed out the piping in a day. In short. This place answers the phone. Gets technician on the job quickly. Great knowledge. Cleaned thoroughly before leaving.

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!
