Taking the Sticky Out of Summer

Brick Street Plumbing Heat & Air offers whole-house dehumidifier installation in Leesburg, VA, connecting a dedicated dehumidifier to your ductwork or setting it up to dry a basement or crawlspace. Our technicians assess where the moisture is coming from, size the unit to the space, and place and drain it correctly, so you are not emptying buckets or living with that damp, clammy feeling all summer. If your home feels humid even with the AC running, call us to talk it through.

Northern Virginia summers are hot and humid, and Loudoun County homes with finished basements, slab-level rooms or crawlspaces often hold onto that moisture well after the weather breaks. Too much humidity encourages mold and mildew, makes rooms feel warmer than the thermostat says, and can warp wood floors and trim over time. A whole-house dehumidifier controls moisture across the home and runs quietly out of sight. We install them in Leesburg, across Northern Virginia, and in nearby Maryland and West Virginia towns.

WHY THE AC IS NOT ENOUGH

Your Air Conditioner Removes Some Moisture, Not All

An air conditioner pulls water out of the air as a side effect of cooling, but it only does that while it runs. On mild, muggy days the AC barely runs, and an oversized system cools the house quickly and shuts off before it has dried the air. Basements are another gap, since they stay cool and rarely call for cooling at all. A whole-house dehumidifier works on humidity directly, on its own control, whether or not the house needs cooling. If your AC is short cycling, leaking or not dehumidifying the way it used to, that may be a separate issue worth an AC repair visit before adding equipment.

SIGNS OF EXCESS HUMIDITY

Clues Your Home Is Holding Too Much Moisture

Most people notice the smell first.

Musty Basement Smell

That earthy odor usually means mold or mildew is growing somewhere damp, often on stored boxes, drywall or carpet.

Condensation on Windows

Fogging or water beads on the inside of windows and cold pipes point to moist indoor air.

A Clammy, Sticky Feel

Rooms feel warm and heavy even at a normal thermostat setting, so people turn the AC down further.

Mildew Spots

Dark speckles on bathroom ceilings, closet walls or the backs of furniture placed against exterior walls.

Swelling Wood

Doors that stick in summer, cupping floorboards and warped trim all respond to moisture in the air.

CHOOSING A UNIT

What We Weigh Before Recommending One

Getting the right dehumidifier starts with the size of the space, since capacity has to match the area being dried. We look at how humid the house actually runs and whether there is visible mold or mildew to deal with. Energy efficiency matters because the unit may run for long stretches in summer. We also consider maintenance and access: the filter needs regular changing, so the unit should sit where you or a technician can reach it. Whole-house units can tie into the existing ductwork or serve a basement or crawlspace on their own.

INSTALLATION

Placement, Drainage and Controls

A dehumidifier pulls gallons of water out of the air, and that water has to go somewhere. Because our technicians are dual-certified in plumbing and HVAC, we route the condensate to a floor drain, a sump pump pit or a condensate pump, and mount a wall control so you can set the humidity level you want. Pairing the dehumidifier with a whole-house air purifier handles both moisture and airborne particles. Browse our full list of HVAC services for related work.

Frequently asked questions

What humidity level should a home in Northern Virginia stay at?

Aim for a moderate level, below the point where the air feels sticky and above the point where it feels dry. Most comfort and building guidance points to keeping relative humidity at or under the midpoint of the scale in summer. Above that, mold, mildew and dust mites thrive. Too low, especially in winter, and skin and wood dry out. An inexpensive hygrometer shows where your house sits, and a whole-house dehumidifier lets you set a target and hold it.

Is a whole-house dehumidifier better than a portable one for a basement?

For a finished or frequently used basement, usually yes. Portable units have small tanks that fill quickly, need emptying, and often cannot keep up with a large space. A whole-house or basement-rated unit has more capacity, drains on its own through a hose or pump, and runs on a wall control. A portable unit can still work for a small room or occasional use.

Where does the water from a whole-house dehumidifier go?

It drains continuously through a hose or pipe, so there is no bucket to empty. The usual routes are a nearby floor drain, the sump pit, or a small condensate pump that lifts the water to a drain or outside. We set up the drain line as part of the installation and make sure it runs downhill or through a pump so water does not back up into the unit.

Can a whole-house dehumidifier help with mold in my Leesburg home?

It helps prevent mold by keeping humidity too low for it to grow easily, which is the main long-term fix in damp basements and crawlspaces. It does not remove mold that is already established, so existing growth needs cleaning or removal. It also will not fix a leak or groundwater problem. We can check whether a plumbing leak or drainage issue is feeding the moisture.

How much maintenance does a whole-house dehumidifier need?

Not much. The main task is changing or cleaning the air filter on the schedule the manufacturer sets, often a few times a year. The coil and drain line should be checked periodically so dust and slime do not build up. We can look at the dehumidifier during regular HVAC maintenance visits so it gets attention along with the rest of the system.
