Dealing with hot and humid weather? Finding mold or mild? High humidity can have several effects on your home and environment as well as your comfort and health. Fortunately, there are dehumidifier systems designed to complement your HVAC system that are capable of dehumidifying your entire home.

Installed to work in conjunction with your home’s heating and cooling system, the whole-house dehumidifier draws air through the return ductwork. The moist air is then pulled into the unit and cooled, which causes the moisture in the air to condense into water droplets. The drips of water fall into a collection pan or are drained directly down the drain, while the dry air is then passed over warm coils to bring it back to the desired room temperature.

What do whole house dehumidifiers do?

Whole house dehumidifiers moderate the overall humidity inside your home. They can be installed in new or existing homes and offer a solution to control moisture levels. Compared to portable units that only control the humidity in one room, whole house dehumidifiers work effectively throughout your entire home.

What are the benefits of having an HVAC dehumidifier?

  • Cooling dry air is easier than moist air, thus AC units work more efficiently.
  • Whole-house dehumidifiers require minimal maintenance.
  • Every 4% humidity you go up or down feels like 1 degree Fahrenheit
  • Every 1 degree you increase your thermostat equals 4% savings in your energy bill
  • Reduce dust mites, spiders, mold mites and creepy crawlies in your basement when you reduce your relative humidity to <50%.
  • There is  also a huge recall on portable dehumidifiers which makes the whole home 1850 more desirable.

How do I know my home needs a whole home dehumidifier?

If any of these issues occur in your residence, you should consider one of these systems:

  • Indoor humidity is higher than 50% in your home.
  • Increased condensation on your home's window panes.
  • Mold or mildew found in your home.
  • Increased amount of bugs in your home.

What conditions need the assistance of a dedicated, high-efficiency dehumidifier?

  • New home construction with low infiltration rates reduces sensible demand and air conditioning run time, resulting in less latent humidity removal when it’s needed most.
  • In the south there are many part-time, seasonal residents who are not at home in the summer months and air conditioners run less often, therefore humidity continues to build.
  • In the north, the temperature of the ground is around 54 degrees and full of moisture. In a basement, you cannot avoid high humidity. This is why most homes with a basement have a portable dehumidifier.
  • In a crawl space, wood floor joists are typically the coldest surface. This is because the interior of the home is air conditioned and the cold air temperature transfers into the structure. If the dew point is not controlled, water will form on the surface of the floor joists, over time, causing the wood to decay and lose its strength.
  • Attics can build up damaging, unhealthy levels of humidity.
