Humidifiers & Dehumidifiers

Whole-home humidity equipment pulls moisture out in July and puts it back in January, so 72 degrees actually feels like 72 degrees.

Humidifiers & Dehumidifiers in Loganville, GA

Whole-home humidifiers and dehumidifiers keep the moisture in your air at a healthy, comfortable level, adding it back during dry winter months and pulling it out during sticky Georgia summers. Keep Smiling Plumbing, Electric, Heating and Cooling has served Loganville homes since 1985, and humidity control is one of the most noticeable comfort upgrades we offer through our HVAC services. We’ll measure whether your home is too dry, too damp, or both depending on the season, recommend a system that fits, and give you written pricing upfront.

what’s covered

What Are Whole-Home Humidifiers and Dehumidifiers?

Both are installed as part of your HVAC system, so they treat the air throughout your entire home instead of a single room. A whole-home dehumidifier pulls excess moisture out of the air and drains it away automatically, which helps on humid days when your air conditioner alone can’t keep up. A whole-home humidifier adds moisture to the air as it moves through your ductwork, which is especially helpful when your furnace or heat pump is drying out the house all winter. Both are controlled by a humidistat, which works like a thermostat for moisture. It keeps your home in the target range on its own, usually between 30 and 50 percent relative humidity, so you never have to think about it.

Signs Your Home’s Humidity Is Off Balance

  • A clammy, sticky feeling indoors even when the AC is running
  • Musty smells, mildew spots, or condensation on windows and vents
  • Dry skin, cracked lips, and frequent static shocks every winter
  • Wood floors, trim, or furniture that crack or separate during dry months
  • Allergy or sinus symptoms that flare up during certain seasons
  • Portable humidifiers or dehumidifiers that need constant emptying or refilling

Benefits of Whole-Home Humidity Control

Humidity has a bigger effect on how your home feels than most people realize. Too much of it makes 74 degrees feel muggy and gives mold and dust mites a place to thrive. Too little dries out your skin and sinuses and leaves you getting zapped every time you touch a doorknob. Once your humidity is balanced, the whole house simply feels better, and you’ll often find you can set the thermostat a little higher in summer and a little lower in winter without giving up comfort:

  • A cooler, crisper feel in summer without cranking the thermostat down and running up the bill
  • Less risk of mold, mildew, and dust mites, which all thrive in damp air
  • Relief from dry skin, scratchy throats, and static shocks during heating season
  • Protection for hardwood floors, trim, cabinets, furniture, and musical instruments
  • No more hauling, emptying, or refilling portable units from room to room

How to Choose the Right Humidity Control System

The right solution starts with figuring out whether your home is too humid, too dry, or both, depending on the season. Here’s how the main options compare:

  • Whole-home dehumidifiers: best for homes that feel sticky in summer, have musty odors, or have damp crawlspaces or basements
  • Bypass humidifiers: a simple, budget-friendly option that uses your furnace’s airflow to add moisture
  • Fan-powered humidifiers: add more moisture than bypass models and work well in larger homes
  • Steam humidifiers: offer the most precise control and work even when the furnace isn’t running

Many Loganville homes benefit from both a dehumidifier for summer and a humidifier for winter. Your technician will measure your home’s humidity levels and talk through options at a few price points, so you can choose what makes sense for your family.

Portable Units or a Whole-Home System?

Portable humidifiers and dehumidifiers can help in a single room, but they’re noisy, take up space, and need to be emptied or refilled constantly. A whole-home system works through your ductwork, covers every room, and drains or refills automatically. If you’re already managing more than one portable unit, a whole-home system is usually the easier and more effective long-term choice.

Common Humidity Problems in Loganville Homes

Loganville’s climate swings between two extremes. Long, muggy summers load the air with moisture, while months of winter heating dry it out. Spring and fall bring humid days that aren’t hot enough for the AC to run long, so moisture lingers indoors with nothing to remove it. These are the humidity issues we see most often:

  • Air conditioners that cool the house but still leave it feeling damp
  • Musty odors and mildew in crawlspaces and basements
  • Condensation and mold forming around windows and AC supply vents
  • Dry, static-heavy air when the furnace or heat pump runs all winter
  • Hardwood floors and trim that swell in summer and gap in winter

Humidity Control Throughout Loganville

Here are some of the neighborhoods where we help homeowners get comfortable:

Humidifier and Dehumidifier Costs and Financing

The cost depends on the type of equipment, the size of your home, and the drain, water, or electrical connections the installation requires. Steam humidifiers and whole-home dehumidifiers generally cost more than bypass humidifiers, but they also do more. We’ll provide a written price before starting any work. To make larger upgrades more manageable, financing through Service Finance and Chowder is available. Keep Smiling Club members also get annual heating and cooling tune-ups and 10% off repairs.

Humidifiers and Dehumidifiers in Loganville FAQs

Indoor air can contain dust, allergens, pet dander, mold spores, and pollutants. Improving filtration and air cleaning helps reduce odors, allergens, and airborne contaminants throughout your home.
For many homes, yes. Better filtration and air cleaning can reduce dust, pollen, and pet dander. We can assess your home and recommend the right solutions.
Most repairs include a one-year labor warranty unless noted otherwise, with coverage up to 12 years in some cases. Parts and equipment include at least a one-year warranty, with up to 12 years on select systems.
Yes. We offer financing options for larger repairs and replacements, including promotions like 0% APR for 60 months with equal payments, plus rebates on qualifying equipment. Ask us about current offers when you schedule.
It does, but only while it’s running. On mild, humid days in spring and fall, or in homes with an oversized AC, the system may not run long enough to pull out enough moisture. A whole-home dehumidifier handles humidity on its own, regardless of how much cooling you need.
Most homes are comfortable and healthy between 30 and 50 percent relative humidity. Levels above 60 percent encourage mold and dust mites, while very dry air can irritate skin and sinuses. Dry air can also damage wood floors and furniture over time.
Yes. Whole-home humidifiers connect to your home’s water supply so they can add moisture automatically without being refilled. Many also need a drain connection. Our team can handle both during installation.
It can if humidity is set too high for too long. That’s why whole-home humidifiers use a humidistat to keep moisture within a healthy range. We’ll set it for your home and show you how to adjust it as the seasons change.
Yes, and many Loganville homes benefit from both. The dehumidifier handles muggy summer months and damp shoulder seasons, while the humidifier adds moisture back when winter heating dries out the air. Each runs only when it’s needed.
Most whole-home humidifiers need a new water panel or pad about once a year, and dehumidifiers need periodic filter changes and drain checks. Keeping up with this simple maintenance helps the equipment work efficiently and last longer. We can take care of it during your regular HVAC tune-ups.
