What is a Dehumidifier?

A dehumidifier is an appliance that removes moisture from the air. So what are the signs that you need a dehumidifier? The experts at Chaves Heating & Air Conditioning can help.

There are a Number of Things That can Indicate You Need a Dehumidifier:

Condensation on Your Windows or Doors

You will see water beading or fog/vapor on the glass of your windows. This moisture will eventually rot the wood and will also allow mold to grow.

Mold Spots on Your Ceiling or the Corners of Your Walls

Moisture rises so you will often see evidence of mold or the beginning of mold up around where the walls meet the ceiling.

Musty odor

A must odor is another indicator that there is too much moisture in your house. Often these smells will come from a basement, crawl space, laundry room, entrances or garages. Musty or moldy smelling towels and bedding will let you know that your laundry room is one place where moisture is too heavy.

Reoccurring Spring Water Run-off

A lot of homes have reoccurring spring water run-off. This results in a damp basement where you will see white or grey water level marks.

Blistering Paint or Peeling Wallpaper

When there is excess moisture in the air it can penetrate the wall. It then turns to steam and will cause your paint and wallpaper to lose adhesion. This will then result in bubbles or peels.

Creaky doors/windows/floors

As wood absorbs moisture it expands, this causes joints, screws and the structural frame of your house to loosen.

Any or all of these things can be evidence of too much moisture in your home. New homes and remodeled homes have better insulation than ever before. This cuts your energy costs overall, but it also creates less air flow and therefore traps humidity. So while you are saving money on gas/oil/electricity you may be creating another problem for yourself that, when left unchecked, can lead to costly repairs.
