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

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.

What Our Clients Think Of Us


Mike came by for an A/C maintenance check up. He came on time and was very friendly and professional.
Response from the owner:Hi Larry, thank you for taking the time to leave us such a positive review about Fabio. We are delighted to hear that he was on time and provided excellent service. We appreciate your feedback and are glad that you had a good experience. Thanks again!
Excellent service very knowledgeable Niko send him hereafter
Tino was exceptional in sevicing both of my AC its. I renewed my contract with Aztil and I look forward in having Tino service me again Thanks for great service
I had to have my air conditioning HVAC system replaced. I bought RHEEMS from them nine years ago or just shy of nine years ago and I had to have the whole thing replaced. It had a leak. The pressure was down 3 pounds and to pay $475 only because I had a contract with them otherwise it would’ve been 675 to check for the leak.. I decided to replace it cause I knew it was around the corner anyhow. They installed it the next day I couldn’t have been more pleased. It was effortless. It took them a while because we had some rain on and off and they couldn’t be on the roof, but they came at 9:30 and they left at 3 o’clock. I thought they did very well. They left my house clean as a button just exactly the way they found it. They were very polite and did everything that they were supposed to do in a very neat and tidy and timely manner.
Jorge and David were the installers today. They were timely, professional, mannerly, exceptionally clean and efficient. And Sabrina in their office went beyond in responding as the cost of new units today is sticker shock!
Nico is absolutely amazing! Very informative and an excellent technician! This is the second time we’ve had him and he’s great
Response from the owner:Hi Kathy, Thank you so much for your wonderful review! We're glad to hear that you had an excellent experience with our service. We pride ourselves on our knowledgeable staff, and it's great to know that Ramon was able to provide you with such great service. We appreciate your feedback and hope to see you again soon!
After 40 hours without A/C in August we were saved by Rafael. He was polite, professional and courteous. He is an asset to the company. On another note, the scheduling system used for after hours is quite poor and needs to be looked into. Thank goodness Jackie called us and attempted to remedy the situation.
Naraldo Bunsie did an excellent job installing my new Trane A/C! Thanks !
Michael was very knowledgeable and efficient in providing service for us today. We’d love for him to come again
Your service techs and general service has improved since the corporate take over. Raphael Curci was efficient and kept us u[p to date on the progress of the installation. The person I'd like to call out as exemplary was Nico who guided us through the process and went out of his way to help us through this time. Ultimately the air handler was faulty and it took several visits to repair it. Meanwhile the handler leaked water all over the garage ceiling ruining it and causing damage to my model trains beneath. In addition the last tech broke my cable power supply which he had no business touching. I had to call Xfinity to come as an emergency for which they charged me $150.00. I will also be sending Aztil a bill for the repair of my ceiling and any damage done to my model trains.
Dana just finished a service call. He was very professional and explained to me what he was doing and gave me tips for the future. I have been an Aztil customer for many years and people like Dana keep me coming back.
Response from the owner:Hi Don, thank you for your kind words! We're so glad to hear that Angel did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.

I recommend Aztil Air everything was done to perfection

He was fabulous! Even at installation, no one ever told me what I was supposed to be doing! You have a great asset in Michael!

I LOVE this company and Nico is hands down the number one technician on the team. The maintenance plan is worth every penny and I never have a problem getting anyone out when I need them.
