Have you started to notice higher levels of humidity outdoors? The humidity always spikes around this time of year because warm air has the capacity to hold more water than cool air. Coming off of the winter dryness, this may seem like a relief. However, when your indoor humidity begins rising to excessive heights, it can impact your health and the health of your home. What does indoor humidity mean for you and what can you do about it? The experts at Newcomb and Company are here with insight.

Why Does Home Humidity Matter?

While some humidity is necessary for keeping your skin healthy and the air fresh, too much moisture can spell trouble for you and your home. You might first notice the irritation that high home humidity can provide. The moisture and heat can make your home feel uncomfortable. Upon closer look, this could be the least of your concerns when it comes to home humidity.

One of the primary concerns of humidity is the potential health risks it poses. This moisture can become a breeding ground for mold and bacteria, leading to poor air indoor quality and other health concerns. These concerns also extend to your home. Over time, mold and bacteria growth can cause rot and even structural damage. This may also make your home more difficult to sell when it is time to move.

Why is the Air Inside of My Home Humid?

When your air conditioning system cools the warm and humid outdoor air, it releases all of the extra water it was carrying. This transition can produce up to 20 gallons of water each day, which is caught by your drain pan and released outdoors by your condensate line. If your air conditioning system is leaking or broken, this extra water may get stuck indoors. This could be an issue with your drain pan, your drain line, your evaporator coil, or another component of your system.


The Department of Energy suggests that the best way to save money on your HVAC energy usage is to set your air conditioning system to the highest comfortable temperature. However, if your system is set too high, it will not convert to cool, comfortable air or release the excess moisture entering your home. The same goes for broken air conditioning systems. Without the cooling effects of your air conditioner, your indoor air humidity will remain unaffected.


Humidity in your home may be let in by unwanted ventilation. If your air conditioning system is working perfectly, cracks and broken seals in your home could still let the humid outdoor air inside. Not only will this lead to higher humidity in your home, but it will also strain your AC system and lead to higher monthly electricity bills.


If you have a leaky pipe, a broken fixture, or another plumbing problem, it could be leaving extra standing water in your home. Not only could this cause water damage, high water bills, and plumbing concerns, but it could also be creating harmful levels of humidity. This compounded concern makes it essential to call a plumber at the first signs of a leak. A professional can help you identify and fix the source of the problem before the damage spreads.


Many of your daily activities could be releasing humidity in your homes. For example, cooking, hot showers, running the kettle, watering your plants, and hanging clothes to dry inside can all release moisture. These are not activities you have to give up because of the humidity they cause, but it is important to remain aware of the moisture in your home and take measures to prevent it.

Your home’s humidity may be sourced to one or more of these problems. Identifying and caring for your home as early as possible can minimize the damage done and the cost of any needed repairs.
