We all know how St Charles and St. Louis get hot during the summer! And what do they say? The humidity definitely makes it worse! Fortunately, there are plenty of things you can do to reduce the humidity in your home.

How to Lower Humidity Levels in the Home

The folks over at Everyday Workbench go over how to reduce your home humidity, prevent mold, and make your home more comfortable in the summer.

Home Humidity Hot Spots

Feeling humidity is often the first sign. The Environmental Protection Agency reports that humidity can lead to mildew and mold. You could go out and buy a hygrometer at a hardware store to get an official humidity reading, but really you can just look for simple signs of condensation on mirrors or windows – the first sign of mold or mildew. Your first task is to locate problem areas, then eliminate those issues. Here is a list of the most common places to check:

HVAC Maintenance

If you check your HVAC unit, you can find your condenser coil. Check to make sure it isn’t dirty and blocked. Check and change your air filter. Remember, having a clean and efficient running system is a great way to try to prevent illness and have better indoor air quality. No Problem Heating & Cooling offers a regular maintenance plan for your HVAC system.

Too Many Plants

We know, we know. You love the jungle in your house! It really is the best feeling when you can bring a little bit of the country life into your home. The problem is: plants retain water as humidity. Lots of plants means lots of moisture.

Proper Bathroom Ventilation

The bathroom is a big hot spot for humidity. Using the shower and tub is the easy culprit. Check the caulking around the tub, shower stall, and windows. Making sure you have a good seal will help reduce drafts and moisture. Adding a exhaust fan will also help eliminate extra humidity in the room as fast as possible.

Windows and Doors

Something as simple as a poorly fitted floor can lead to air leak and increased humidity in the home. Check all exterior doors and windows for proper weather stripping and caulking. It is a good idea to review these points in your home every spring and fall.

Roofing and Basement

These areas can be common sources for increased humidity levels in your home. The smallest roof leak can lead to pooling water, mold growth, and structural damage to your home. Crawl spaces and basements are easily top spots for humidity culprits as well. The proper sealing of a basement can either make or break the fight against home humidity.

Home Humidity Solutions

We are going to tackle the solutions. Remember you cannot ever get rid of humidity 100%. It’s just not possible and you don’t want to. It is finding the balance of just the right humidity that is comfortable and healthy. These are ways that during these hot summers in St Charles that we can slow high humidity down.

Make Necessary Repairs

Ensuring your home remains sealed and well-maintained is crucial for maintaining proper humidity levels, energy efficiency, comfort, and structural integrity. Regular inspections and necessary repairs play a pivotal role in this process. Addressing issues like damaged weather stripping, cracked caulk, or gaps around doors and windows can prevent drafts, moisture infiltration, and pests from entering your home. Repairing leaks in the roof, siding, or foundation preserves the building’s structural integrity and prevents water damage. Routine maintenance of your HVAC system, including sealing ductwork, enhances insulation and minimizes energy wastage. By proactively making these repairs, you’ll maintain a comfortable, energy-efficient, and secure home environment while potentially saving on utility bills and costly future repairs.

Circulated Air

Make sure your home has good air circulation. Get those ceiling fans or portable fans moving. If you have ventilation fans in the bathroom or the kitchen, use them after showering or while cooking. If the weather is good and your family doesn’t suffer from allergies, open windows and doors and let the air blow right through the house.

Add a Ductless Mini Split

Sometimes adding a ductless mini-split can tie up two loose ends at once. Mini-split AC systems can also effectively manage home humidity by employing features like dehumidification mode, continuous operation, zoned cooling, and variable speed compressors. These systems can remove excess moisture from the air, maintain consistent indoor humidity levels, and prevent overcooling. They’re energy-efficient, and as long as you pick the right size and give the regular maintenance, they’ll keep your home comfy and dry.

Add a Portable or Whole-House Dehumidifier

Depending on the humidity pain points in your home, you could consider installing either a portable or whole-house dehumidifier. Portable dehumidifiers can be bought almost anywhere and are perfect for resolving humidity issues in a single room or basement corner. If you have humidity concerns in multiple rooms, you might consider an air purification system or whole-house dehumidifier incorporated into your HVAC system by professionals like No Problem Heating and Cooling.

We had a major repair needed and they came quickly and gave their opinion and our options for repairs needed. After reviewing the bids we had from other competitors, we chose No problem Heating and Cooling to replace our HVAC system in our home. The installation was done in a timely manner and everything was professional throughout the entire process. The details for our new efficient unit was explained and all of our questions answered. I recommend No Problem Heating and Cooling for any major or minor repairs needed.

 Trustindex verifies that the original source of the review is Google. We had a great experience with No Problem Heating and Cooling! My AC went out, and they were able to get me scheduled quickly after I called. They came out, figured out what was wrong, and explained my options without being pushy about selling me anything. I ended up repairing my current AC but when it’s time to replace it, I’ll definitely be calling No Problem again. They also told me about their air purification systems, and with my allergies, I decided to have one installed. I’m really looking forward to having cleaner air in the house. Thanks for everything! Great service, honest recommendations, and super easy to work with. I definitely recommend No Problem!

 Trustindex verifies that the original source of the review is Google. Casey and Donna both worked so hard to get our air conditioner working and back to normal.  I cannot tell you how much it meant to my husband and I.  When Casey walked into our home, it was almost 90 degrees, and thanks to both of them - less than 12 hours later - it was a perfect temperature.  Even while experiencing a heat wave, our air conditioner works perfectly! THANKS TO DONNA for arranging his crazy busy schedule to fit us in as an emergency and THANKS TO CASEY, for his knowledge and expertise on how to fix the problem in less than an hour.  I WILL ALWAYS YOUS NPM HEATING & COOLING LLC, and will recommend them to all of our family and friends.  I can't tell you how grateful we are.  Thanks again.  Laura Ray
