Breathe Easier with GEM

Are you struggling with high humidity in your home? Too much moisture can make the air feel damp and heavy, leading to musty odors, foggy windows, warped flooring, and even mold growth.

Some homeowners start with portable dehumidifiers, but those small units often can’t keep up. If you’re tired of emptying buckets or still noticing moisture problems, a whole-house dehumidifier is a more reliable, long-term solution. It automatically removes extra humidity throughout your entire home, helping you maintain cleaner air.

At GEM Plumbing & Heating Services, LLC, we make installing a whole-house dehumidifier simple and stress-free. Our licensed, NATE-certified technicians will recommend the right system size and type and install equipment that integrates seamlessly with your HVAC system. With GEM, you can enjoy a healthier, more inviting home, free from moisture buildup and the problems it creates.

We had a leak in the feed tube going into our toilet. It leaked down through the ceiling into our kitchen. I called GEM and they sent technicians right out to fix the problem. The technicians arrived, assessed the problem and gave us a very reasonable quote. The technician also noticed veteran plates on my car and applied a 10% discount! They fixed the problem, noticed that the feed tubes to my sink didn't look good and corrected them as well. Both technicians were very personable and kind. They helped lower our anxiety as well. Great experience! Highly recommend GEM plumbing!

Two great gentlemen (Brandon and Maxwell) came to my house to fix a leaking faucet. They explain all the questions from me and wife. They even give nice advice about reglazing the sink. Due to the distance between the cabinet and the sink, they tried very hard to find the best possible solution for us and install a new faucet. It is a wonderful job!! Highly recommended!!
The GEM service technicians showed up promptly. They were quick and efficient with their service. They had good recommendations and were very cordial. I would call on them again.

I have already posted a 5 star review and want to post another. Four years after becoming a GEM customer, I remain totally satisfied with their service. I could name a lot of names: Nathan Campbell, Tony Rossi, Michael Hassel, Steven Gray and his partner Chase, and others who have all been incredibly responsive and totally dedicated to solving the problem at hand. I think for an organization as large as GEM they have managed to recruit and train a great group of professionals. All that matters to me is quick access to such a good group caring pros.

The service and attention to detail is excellent. They identified the problems with 2 toilets and 2 shower faucets and resolved every issue with the least amount of disruption. They even went the extra mile to identify the cause of a ceiling stain to make sure it wasn't from water. I recommend them highly for quality of work, knowledge and efficiency.

Common Signs You Need a Whole-House Dehumidifier

Many homeowners don’t realize the impact of high indoor humidity until it becomes noticeable.

Here are some common signs that your home may benefit from a whole-house dehumidifier:

Dew on windows, damp walls, or wet floors can indicate elevated humidity levels. Over time, this moisture can damage wood, paint, and furnishings.

If your home has a musty odor or visible mold in basements, closets, or bathrooms, it’s a clear warning that moisture levels are too high. Dehumidifiers help prevent mold growth and protect your home.

High humidity levels promote dust mites, mold spores, and other allergens. If family members experience frequent allergy symptoms or respiratory irritation, a dehumidifier can improve the air quality in your home.

Humidity can cause doors and windows to swell, making them difficult to open or close. Controlling moisture helps maintain smooth operation and prevents long-term damage.

Portable vs. Whole-House Dehumidifiers: What’s the Difference?

You know you need to reduce the humidity around your home, but you’re not sure what the right choice is.

Homeowners typically have two main options; invidual portable dehumidifiers and whole-home systems. Ultimately, the choice will come down to the area you want covered, as well as some other factors. Consider things like:

Portable dehumidifiers work well for single rooms or smaller spaces, while whole house systems are designed to manage moisture throughout the entire home. The square footage you want to control plays a major role in which option makes sense.

Portable dehumidifiers are simple to set up and require no permanent installation. Whole house dehumidifiers require professional installation and integration with your HVAC system, which is a bigger upfront commitment.

Portable units need regular emptying or drain management and frequent filter cleaning. Whole house systems usually require less hands-on maintenance once installed, with service handled during routine HVAC checkups.
