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

Mini-Split Installation That Exceeded Expectations

Gwen Anderson

Jake is amazing! We reached out to get a quote for a mini-split system to cool our server room, and Jake exceeded our expectations. He recommended a more cost-effective solution that has provided us with incredible results. His out-of-the-box thinking and thoughtfulness are so impressive. I had six other HVAC companies provide quotes, but Jake was the only one who made sustainable and well-considered suggestions. The office staff is also super friendly and helpful!
Came Right on Time for Our

Dominique Haffery

We just had Master Mechanical service our AC units before it gets too hot! This way we know they are operating efficiently! I used to be scared to pay money for these things but it truly saves money in the long run! Master Mechanical was able to come out quickly, give me a shorter window then most companies do in this trade, came right on time, communicated the whole way! They are professional and experts at their craft! Highly recommend!!!
A Great Company for Complicated HVAC Problems

Eric Williams

Jake did an excellent job helping me solve a complex problem that no one else could help with - I needed a new thermostat installed for a unique 120V water chiller AC system, and all other HVAC companies refused to work on it. Jake was on time, friendly, informative, and had it done in less than an hour. Highly recommended!
Saved $1000 With a Second Opinion on AC Repair

Kris

I’m glad I called Master Mechanical for a second opinion. They saved me $1000 over the quote for the same repair from another HVAC company. They were professional on time and fixed my unit same day. They also weren’t pushing upsales. They did let me know my options, but unlike the other company, Master Mechanical didn’t try using scare tactics to get me to buy additional services. Master Mechanical will be my first choice going forward and I’ve already recommended their services to family members as well.
Repaired My Boiler Instead of Pushing an Unnecessary Replacement

Kathleen Ferraro

I am so grateful to Master Mechanical for repairing my old boiler. Danny Chee is very knowledgeable and was able to figure out the problems and repair them. Plus he is a very nice, polite person. He made sure everything was working correctly before leaving, even after 5:00. The people on the phone, Paul and a woman whose name I can't recall, are professional and helpful. I received texts and emails confirming appointments and letting me know when Danny was on his way. They could have sold me a new boiler but instead fixed the old one at a fraction of the cost. I highly recommend them and will continue to rely on them in the future.
