What to Do When Your Home Feels Too Humid Inside

Although your home needs a certain amount of moisture in the air for health and comfort, too much humidity can be damaging. In fact, high levels can lead to various issues if left untreated such as allergies, mold and rot. Frankly, rot can cause excess damage to your furniture and even the home’s structure. Typical signs of too much moisture include a sauna like feeling when you enter a room, a musty odor, mold in the bathroom, condensation on the windows and water stains on ceilings and walls.


Conferring to the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), the best humidity for humans is a range between 30 to 60 percent. In fact, the ASHRAE states that humidity above 60 percent can contribute to mold and various diseases. Moreover, people who have problems with allergies, asthma and other respiratory disorders should not allow the humidity to exceed 50 percent. Likewise, many home builders and experts recommend humidity levels for a house range between 35 to 50 percent.

Measuring Humidity Levels

Fortunately, you can change the humidity levels in your home at minimal cost. One of the best ways to check humidity levels in your home is with a hygrometer. The device can easily and accurately calculate relative humidity. As well, a hygrometer can monitor the humidity levels in your home. If you find that the humidity levels are too high, there are various actions you can take to remedy the problem.


Look for Moisture Sources

Excess humidity can be caused by a variety of sources. Prime examples include improper ventilation, a damp and moist basement, wrong sized heating and cooling system, a leaky roof or even too many plants.

First, start with the easiest jobs. For instance, lay down a moisture barrier in the basement to prevent moisture, fix all leaks in the roof and check to see if your heating and cooling system is the proper size for your home. Other sources that can create excess moisture are poorly ventilated clothes dryers and minimal fans in the bathroom and kitchen.

Lastly, if the moisture issue continues, hire an HVAC specialist, such as those at Apollo Heating & Air Conditioning, to check your heating and air conditioner system. A professional can make sure that you have the right size system for the square footage of your home.


Sometimes, getting rid of excess humidity can be very challenging. For instance, certain lifestyles like an apartment make it difficult to control the atmosphere. In fact, many variables may be out of your control like the age of the building, heating sources and other tenets’ standards of living. The best solution in this case is a dehumidifier. The device can help reduce the moisture by pulling some water out of the air. Generally, portable dehumidifiers can be found in most department or hardware stores. However, if you own your own home it is recommended that you contact an HVAC specialist to install a specific appliance like a heat pump dehumidifier.

Other Remedies

Other remedies for high humidity include improving drainage like redirecting runoff from gutters, install an air exchange such as fans in the crawlspace, use your bathroom exhaust fan, inspect the drywall for damage and caulk the windows and doors where there are signs of moisture damage.

Hopefully, the above advice has been helpful in helping you to solve the humidity problems that you may be experiencing in your home.
