Whole-Home Dehumidifiers in Annapolis, Arnold & Edgewater, MD
Chesapeake humidity is relentless — whole-home dehumidification keeps it out of your house.
Dehumidifiers
Waterfront and low-lying homes across Annapolis, Edgewater and Arnold fight high humidity for months at a time. A whole-home dehumidifier removes far more moisture than your AC alone and prevents the mold and musty odors that follow.
Air conditioning removes some moisture, but on mild, damp days it doesn't run long enough to dehumidify effectively. That's exactly when dedicated dehumidification earns its keep.
Target indoor humidity in summer is 45–55%. Above 60%, mold growth and dust mite populations increase sharply.
We size and install units for homes throughout Anne Arundel County, including waterfront properties along the South and Magothy Rivers.

Reviews
What Our Customers Say
“Very professional service, installed A/C unit when my old AC died. He understood my situation and scheduled it promptly. Followed COVID protocol which was a big concern for me. Pricing was very reasonable. Highly recommended.”
“Sunil arrived at the agreed upon time. He was very thorough in his search for the cause of my HVAC failure. He presented an estimate prior to performing the necessary repair with a commitment to revisit with me, if it turned out to be more, prior to performing any additional work. He showed me the problem and provided an explanation as to the cause of the failure. After the repair he inspected the rest of the unit and provided an assessment on the performance of the other components. I highly recommend Proactive Htg and AC for HVAC service and repairs. Professional and reasonable!”
