Expert Dehumidifier Installation and Maintenance
When the air in your home feels heavy and damp, it isn't just uncomfortable—it can lead to mold growth and structural damage. The certified technicians at Active Heating are ready to restore balance to your home with professional dehumidification solutions. We stand behind our work, ensuring your indoor environment remains dry, healthy, and energy-efficient.

Common Signs Your
Home Has High
Humidity
Excess moisture often manifests in ways you can see and smell. If you notice these issues, your AC alone may not be enough to control the humidity:
Do your windows fog up often?
Does your home feel sticky or clammy?
Do you notice musty or moldy odors?
Are there damp spots on walls or ceilings?
Do you see mold or mildew in bathrooms or basements?
AC runs a lot but still feel uncomfortable?

We Service All
De-Humidification Systems
Whether you need to control moisture in a basement or throughout the entire house, our experienced technicians know how to install and maintain the right system for your needs.
Benefits of a Whole-Home De-Humidifier
At Active Heating we have technologies that will kill pathogens like SARS-CoV-1 and seasonal flu in the air inside your home and on the surfaces you and your children touch. Check out the variety of indoor air quality products we offer below!

Consistent Moisture Levels
Whole-home humidifiers are installed in the ducts near your HVAC system. Moisture is added to the air as it is pumped through the vents throughout your home.

Automatically Drained
Whole-home humidifiers are connected directly to your water supply, so there’s no need to continually fill that cumbersome reservoir.

No Bacteria Growth
Our contractor-grade canister will keep mold and mildew from growing and becoming airborne unlike portable humidifiers.

Energy Efficient
Works in conjunction with your HVAC system to only run when it’s running, saving energy and conserving water.

Backed By A Warranty
Our whole-home humidification systems are backed by our contractor-grade warranty for parts!

Protect Your Investment
Using a humidifier will help your wood floors and furniture last for ages.

Control Allergens
Humid air reduces the movement of airborne particles, meaning less dust and allergens, as well as the movement of viruses and bacteria.

Home Comfort
Humid air feels warmer so you can comfortably set your thermostat 2-3 degrees cooler, along with reducing static electricity and helping prevent itchy skin, chapped lips and dry throat!
