Types Of Dehumidifiers

The Best Dehumidifiers Installed Throughout Greater Astoria and the North Coast

What is a dehumidifier and how does it work?

Dehumidification is often part of an overall strategy to improve a home’s energy efficiency, indoor air quality and durability. Removing moisture from "damp" air in a basement or crawl space can help insulation function more effectively while also helping to prevent mold, wood rot and metal corrosion.

A dehumidifier works according to the principle that air's ability to hold moisture (humidity) diminishes as air temperature drops. This principle explains why an ice-cold glass of water “sweats” moisture on a hot day.

In a dehumidifier, a fan blows humid air across a metal coil assembly that is filled with cold refrigerant –the same compound that is used in air conditioners and refrigerators. When the air meets the cold coil surface, water condenses out of the air and drips off the coils onto a reservoir that’s built into the dehumidifier.

Top-quality dehumidifiers provide the best value

Like refrigerators and air conditioning units, some dehumidifiers are better than others. Most of the standard models available through appliance dealers don’t have the capacity or durability for reliable long-term performance in basements and crawl spaces. Fortunately, P&L Johnson Mechanical, Inc has access to top-performing dehumidifiers that easily outperform other models, and are specifically designed to handle the high-moisture, lower-temperature environment of basements and crawl spaces.

One of our exclusive models can dry a 2500sq. ft. basement with an 8-ft. ceiling up to 275% more efficiently than similarly sized models. This dehumidifier has features than engineers admire and homeowners appreciate, and is an ENERGY STAR® Rated product. It's self-draining, so there’s no need to worry about emptying the reservoir. A built-in humidistat allows you to set a desired humidity level. The unit will turn off automatically when a preset humidity level is reached. A high-quality (MERV-11) air filter has been incorporated into the unit, enabling the unit to remove dust and allergens from the air in addition to providing dehumidification.

If you have a crawl space with moisture problems, we also offer sealing and waterproofing products and a low-profile dehumidifier that's just as impressive but is designed to fit in tighter spaces.
