Dehumidifiers

Dehumidifiers are systems designed to remove excess moisture from indoor air, helping maintain a healthier, more comfortable home environment. In Massachusetts, where humidity can lead to mold and air quality issues, our whole-home dehumidifiers offer an effective solution to protect your family and property year-round.

Whole-Home Dehumidifier Benefits for Massachusetts Homes

With unpredictable weather and coastal humidity levels, Massachusetts homeowners often deal with damp indoor air. A whole-home dehumidifier works silently through your home’s ventilation system to balance humidity levels in every room. Unlike portable units, it doesn’t just treat one space — it improves the air throughout your entire home.

More Comfortable, More Breathable Air

Clammy air and sticky surfaces are common with high indoor humidity. Whole-home systems offer a consistent solution.

  • Keeps humidity levels between 30%–50%, the ideal range for comfort
  • Reduces allergens like mold, mildew, and dust mites
  • Helps air conditioners work more efficiently and reduces energy costs

Long-Term Protection for Your Property

Moisture isn't just uncomfortable — it causes damage. A whole-home dehumidifier helps prevent:

  • Warping of hardwood floors and furniture
  • Mold growth in basements, attics, and crawl spaces
  • Peeling paint and bubbling drywall
"According to the EPA, indoor humidity above 60% can cause mold growth in less than 48 hours — even in newly built homes."

Installing a whole-home system ensures long-term comfort and protects one of your biggest investments — your home.

Dehumidifier Installation: What to Expect and Why It Matters

Choosing the right dehumidifier installation process is key to getting the most out of your system. It’s not a plug-and-play appliance — it integrates directly into your home’s ductwork, ensuring optimal airflow and efficiency.

Finding the Best Fit for Your Home

When installing the best dehumidifier for whole house, here’s what matters most:

  1. Proper sizing based on your home’s square footage and layout
  2. Location of existing HVAC components for seamless integration
  3. Type of controls or smart settings available for ease of use

Cleaner Air, Healthier Family

A professionally installed unit improves indoor air quality (IAQ) every day. Benefits of IAQ solutions include:

  • Fewer asthma and allergy flare-ups
  • Fresher-smelling air, even during humid summers
  • Peace of mind knowing your home is dry and safe

If you’re unsure about your home’s moisture levels, you can learn more about humidity recommendations from the Environmental Protection Agency. With the right system in place, you'll enjoy cleaner air and a healthier home all year long.

What Local Homeowners Are Saying

See how SumZero has helped local homeowners stay comfortable year-round with energy-efficient heat pump solutions.

It would be hard to overstate how helpful and flexible SumZero has been. We had to deal with a nightmare H.O.A. filled with busybody people who didn't even know what a heat pump is but were sure they didn't want us to have one. SumZero literally met with the H.O.A. and gave a little presentation. The key to understanding this company is that they are actual real environmentalists and not just business-people trying to make money. They just literally want to move people off of fossil fuel-based systems. It took well over a year, but we finally got our unit installed and SumZero did a fantastic job. They were creative and flexible in moving the unit to our attic, which gave us a new closet when the old gas system was pulled out. They even followed the H.O.A.'s ridiculous and absurd rules about everything outside being totally hidden, even if it was behind a fence.

The Sum Zero team was exceptional- starting with Paul Jameson who was prompt in response, knowledgable and great communication. We got 4 other bids on the job and Sum Zero easily rose to the top. The installation crew were very professional, came on time and asked questions to ensure they were satisfying all our needs. Following the installation, we had a few additional questions about the thermostat- they actually came to the house the next day to walk us through everything again to ensure we were happy. They even submitted the paperwork for MassSave rebates. Any time we call, they deliver. Customer First attitude. Highly recommend.

Paul and his crew did an amazing job on our heating system. When it was not exactly what we had agreed upon after installation, he had his team return and make the adjustments. The next day. Fast and at no charge. He provided quick, friendly and helpful service in an industry not know for timely quality. Thanks to Paul and the guys for a job well done.
