Why Too Much or Too Little Humidity is Bad for Your Home

February 6, 2020


As HVAC technicians, we want you to know your indoor air quality is important for the well-being of everyone in the household. When you have too much or too little humidity in your home, it can cause problems like respiratory issues or mold growth. The Environmental Protection Agency (EPA) recommends a baseline between 30 and 50 percent humidity for the best indoor air quality.

Why Too Much or Too Little Humidity is Bad for Your Home

What Happens When The Humidity Is Too High?

If you notice condensation on the insides of your windows or damp areas on the walls, then it’s likely your house has too much humidity. This can occur due to a variety of issues like poor ventilation, lack of insulation or damp conditions. Appliances like dryers and dishwashers contribute to excess moisture in the air as well as cooking items on the stove. Taking a hot shower is a major contributor to the humid conditions too. When you have high humidity in your home, it can cause structural damage over time. The dampness makes the perfect environment for mold and bacteria to grow in your HVAC unit, and that can cause long-term health problems like allergies and asthma.

What Happens When The Humidity Is Too Low?

You may think that a dry environment would be beneficial to your health. However, when the internal moisture is too low, it can cause an array of health issues. The problems can range from chapped lips, sore throat, dry skin, itchy eyes and can lead to upper respiratory illnesses. Low humidity evaporates the moisture in your body and can make you feel cold. It can also dry out your furniture, wall coverings and hardwood floors. If you have low humidity in your home, then you may notice that you also have a lot of static electricity. An HVAC professional can work with you to help resolve these problems for a more comfortable home.

How Can These Problems Be Resolved?

If your home suffers from too much moisture, then a whole house dehumidifier could be the answer. This type of dehumidifier will regulate the temperature and humidity in the dwelling, and pull moisture out of the air to create clean air. By removing the water from the indoor air, your home will be protected from the spread of bacteria, mold and fungi. For homes that need more moisture, then a humidifier may help balance out the lack of humidity. When you use a whole house humidifier, your indoor air quality will be more comfortable.

Living in an excessively dry environment is hard on the body and on your furniture, so talk to an HVAC professional about the benefits of this unit. Contact the experts at Master Mechanical today for more information on improving your indoor air quality.

Proof We’re the Best HVAC Company Straight From Our Customers

  • Didn’t Push a Furnace Replacement
    Taylor D.
    Tom, the owner was awesome. He came out immediately when our furnace went out and completed a challenging fix. When I asked if I should replace the furnace he said no. Honest and did outstanding work. Furnace is quieter and seems to be running better than when we moved in!
  • Highly Recommended for AC Replacement
    Jeremiah D.
    Tom came over and thoroughly discussed my options. We discussed at length the pros and cons of the most expensive and least expensive options, and came up with a fair price for the products I chose. The crew showed up on time and finished the same day, and was easy to deal with. The new furnace heats my house so much better than the old one. I would definitely use Master Mechanical again. And I have. I’ve now replaced multiple furnaces and AC units using Tom and his crew at Master Mechanical, and would use them again.
  • Quick AC Fix During a Power Surge
    Jim P.
    Master Mechanical responded quickly when our AC failed following a power surge. They quickly diagnosed the problem, and responded patiently to my uninformed consumer questions. Once the team arrived to complete the repair work, they were professional and again, knowledgeable. Prices were fair, and they followed up with me after work was completed. Overall a great company!
  • Last Minute AC Repair
    Rupal P.
    Master Mechanical is an amazing company! I called last minute (per my friend's recommendation) since my ac broke yesterday. Victor was friendly, fast and explained everything and he ended up fixing my issue---thank you! Highly recommend Services A/C system repair.
  • Two Great HVAC Experiences
    Bill L.
    Did an excellent job on two repairs. The first was an emergency call for a furnace repair when it was 4 degrees F outside. They showed up on time, diagnosed the problem, went for parts, repaired the furnace all in about an hours time. The second repair was for the whole house humidifier attached to the furnace. It was a minor issue and corrected in less than 40 minutes. Everything is working great. My experience with their work is excellent.
