Do You Need a Dehumidifier? 5 Signs Your Home Has Too Much Moisture

By Aztil –

Image for Do You Need a Dehumidifier? 5 Signs Your Home Has Too Much Moisture

Are you wondering if you need a home dehumidifier? Florida’s average humidity is 75%, making it one of the most humid places in the US. While we love the sun, sea, and beautiful wetlands, all that humidity is not quite so glorious inside your home.

Just the right amount of moisture is good for your skin and respiratory system. But too much, and suddenly, things get muggy. The ideal temperature inside your home is 30% to 50%. If it is any higher, you may have issues like discomfort and mold growth. ACs can remove some humidity, but there are definitely clear signs that your home would benefit from a purpose-built dehumidifier added to your HVAC system.

The right dehumidifier can enhance the comfort and safety of your home.  Here are the five signs that a dehumidifier will vastly improve your home environment.

1. Persistent Condensation on Windows and Glass

Water clings to cold glass. If your AC has cooled the inside of your windows and you see droplets or fog on the inside of the glass, this means there’s a ton of excess water hanging in the air. Your home’s humidity is likely too high. Excess moisture can seep into the walls and furniture, potentially causing long-term water damage or creating a welcoming environment for mold growth.

A dehumidifier removes excess moisture from the air, keeping windows clear and surfaces safe from moisture damage.

 

2. Musty Odors That Won’t Go Away

Musty odors are a sign of mold and mildew growth. Mold and mildew are tiny fungi that love to grow in moist places. While they are more likely to appear in damp areas like the bathroom or unattended laundry, high humidity can create damp spaces all over the house. You will notice a pervasive musty odor, even if you can’t visibly see the mold.

A home dehumidifier maintains a balanced humidity level, helping keep your home dry enough to discourage mold and mildew growth. This solution both ensures a safer living environment (mold spores can be dangerous) and gets rid of that musty smell.

 

3. Visible Mold or Mildew Growth

Mold likes to grow in out-of-the-way places. But in a damp home, it can grow even in highly visible locations like your walls and ceiling, on your furniture, or in storage areas. Visible mold or mildew is a strong indicator that the moisture levels in your home are out of control. Mold not only damages your home, but the spores it releases pose a serious health risk to your family.

A whole-home dehumidifier can be installed as part of your HVAC system to ensure lower humidity levels throughout the home. Often, this ensures a humidity level below 50%, making it harder for mold and mildew to find a moist place to grow.

 

4. Increased Allergy or Asthma Symptoms

Mold is an allergen that releases spores. If you have been experiencing allergy or asthma symptoms inside your house – especially if they are worst first thing in the morning after breathing the air all night, then mold may be growing in your walls due to excess humidity. If your bedroom feels humid and smells musty, it might even be in your mattress.

By reducing the moisture in the air with a dehumidifier, you can limit the potential for mold and allergen presence in your home. This improves air quality and can alleviate allergies and asthma symptoms.

 

5. Warped Wood or Peeling Paint

Too much humidity is also not suitable for the house itself. Too much moisture will warp wood, causing it to swell out of shape as the wood absorbs moisture. Paint may also soften and detach from surfaces, and wallpaper may peel in high humidity. If you notice warping or peeling along your walls and other home features, the moisture is likely to blame.

A dehumidifier protects your home from water damage and humidity-related decay by keeping humidity levels low. This preserves your woodwork, paint, and wallpaper, keeping everything the way it should be.

 

Why Invest in a Home Dehumidifier?

A dehumidifier is more than just a bonus piece that you can add to your HVAC. In Florida, a whole-home dehumidifier is a key player in ensuring a comfortable, healthy, and long-lasting home.

  • Prevent Moisture Damage – reducing humidity in the air prevents moisture from invading and damaging your home and furniture.
  • Prevent Mold Growth – A low-humidity environment is less likely to foster mold growth.
  • Improve Air Quality – The right amount of moisture in the air ensures better indoor comfort and air quality.
  • Enhance Energy Efficiency – Your HVAC system runs more efficiently in balanced humidity, resulting in lower energy bills.
  • Long-Term Savings – Prevent repairs and excess energy use.

I wanted to commend Dana Dussualt for his hard work at rectifying a substantial issue that I had with my HVAC system. It did require multiple visits but he stuck with it and figured out the issue and did get it resolved. Dana spent hours in the attic in the middle of summer working on getting this fixed. He is both a very hard worker and a pleasant individual. Dana is a credit to your company. In addition, the office staff worked with me in getting these repairs done by insuring we would get service on the date promised. Having no air conditioning in the summer is not a great experience. I have been an Aztil customer for many years.

Yesterday no ac!! Yikes. Dana was the technician who did not leave our house until he discovered and fixed the problem. Believe me, he missed dinner and this was a Friday night. Couldn’t be happier. Dana was so professional and knowledgeable. So happy we bought from Aztil and have a service contract with them. If you ever think it’s not worth having the service contract in case of emergency, when you have no ac and it’s sweltering outside, you will be so happy you made a smart decision! Thank you Dana and Aztil.

Ramon Serpa is the best! He performed the maintenance check on my A/C and when I told him about my husband’s allergy problems, he suggested UV lights which would improve the air quality.

Response from the owner:Hi Susan, thank you for your kind words! We're so glad to hear that Ramon did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
I've been using Aztil for over 20 years across 4 homes in Florida. From general services to complete A/C replacements, I wouldn't trust anyone else. My recent service in Port St. Lucie with Nico was excellent and he was very helpful in going over all of my HVAC system and answered a few questions I had.
I highly recommend Aztil for any HVAC issues or general maintenance.
Response from the owner:Hi Ralph, thank you for your kind words! We're so glad to hear that Niko did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
I cannot speak highly enough of our super kind technician, Randy, who came out to assess our AC today. Randy took the time to walk us through photos of the issues in our AC and offered to take care of it ASAP as he already had the parts in his truck - LOVE the preparedness! Aztil Air Conditioning is superior and we will request Randy on a go forward basis.

UPDATE 6/17/25 - Exceptional Service from True Professionals - Highly Recommend!

We recently had our ducts cleaned and sealed, plus our dryer vent serviced by Jordan and Hero from Aztil Air Conditioning, and I cannot say enough good things about their work. From the moment they arrived, these two demonstrated exactly what professional service should look like.

What impressed us most was their commitment to education - they took the time to walk both my husband and me through every step of the process, explaining not just what they were doing, but why it mattered for our home's efficiency and air quality. It's rare to find technicians who are so patient and thorough in their explanations.

Beyond their technical expertise, Jordan and Hero showed genuine respect for our home and our comfort level throughout the entire job. They worked with care and consideration, treating our space as if it were their own. As homeowners, we've all had those experiences where workers leave you feeling uneasy - this was the complete opposite. We felt completely at ease having them in our home.

Their professionalism, kindness, and attention to detail set them apart in an industry where those qualities aren't always guaranteed. If you're looking for HVAC services you can trust, don't hesitate to call Aztil Air Conditioning. Jordan and Hero will take excellent care of you and your home.

Five stars - we'll definitely be calling them for any future needs!
Response from the owner:Thank you Jessica for your positive feedback. I'm glad you were happy with the support we provided. Please keep us in mind for any HVAC needs.
