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.

Shoutout to GEM Plumbing! They came out to fix my well pump, which turned out to be just a bad breaker. While they were here, I mentioned my mini-split air conditioner wasn't working. Even though it wasn't what they were hired for, they jumped right in to help. Turns out, the disconnect switch was installed upside down! They flipped it right-side up, and boom—AC is back on. That is what you call going above and beyond! 🙌🛠️

Repair person John was very professional and he found the problem in the time he was here. Gem was able to schedule me the same day that I called.
I live in an old building where there are multiple obstacles to consider when installing new bathroom fixtures. Nathan, a master plumber at GEM found a successful solution in a most creative and timely way. Nathan and his associate Kevin were very respectful of my home and left no dirt or garbage behind, just a job well done.

Had a leaking T&P relief valve on my water heater. Called GEM, they came out just a few hours later, replaced the valve with a new one, and they could not have been nicer or more professional. Very satisfied and grateful for their speed and knowledge. Would absolutely call on them again. I did not pay anything because I am under warranty.

We needed a new furnace. They sent someone out the next day to provide an Estimate. The price seemed reasonable and the discounts made it even better so I booked them to complete the job. I received a call later the same day and had the furnace installed the following day by Ethan and Kevin. The following Monday, my furnace would not fire. After evaluating the situation it was found that we needed to relocate our exhaust pipe. Ethan and Kevin were sent to do the job. The original installation was done in less than a day and assessing and relocating the exhaust pipe was done in a few hours. I am happy with the service.

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; individual 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.
