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.

Steven and Diego arrived to check out our system and were able to get everything up and running. They were professionally, efficient and friendly. GEM Plumbing employees are always top notch!
Two technicians came to assess my minisplit which has been leaking. They spent a lot of time working hard to find an answer which unfortunately ended in needing a follow up appointment with a handyman through GEM, to resolve an issue with my unit. But while the techs were here they really tried very hard to resolve the issue. I give them an A for effort.
New resident needing plumber to improve drainage of bathroom sinks and stop leaky faucets. As first plumber I called did not call me back, I called Gem for help. William and Mark were sent to provide service within 2 hours. Problems corrected after thorough discussion of options and pricing for each. Selected the replacement option for leaking faucets, which resulted in spending more money than anticipated, but they selected good looking faucets from supplier and returned to install them. I elected to enter into a one year contract to secure HVAC service for the year, eliminating the dispatch fee. I am pleased with the new well functioning faucets. Good communication with technicians and office representative, Melissa.
They were both great. They explained everything very well.
The best. Great communication, clear pricing, does the whole job and doesn't leave until everything is handled. I have referred them to several people because trustworthy people are hard to find
Very professional and knowledgeable on what needs to be done
Did a great job
The crew.
Was very respectful of my property and worked very efficiently. The clean up after the work was accomplished was impeccable. I highly recommend them without reservation.
Very responsive to my off-hours request for heating repair on a holiday weekend; technician resolved problem. Communication was very good (updates about arrival time, etc.).
John P replaced a capacitor on my AC unit and got it working again. He had to get onto the roof to reach it which is not easy. I asked John a lot of questions about AC and heating units and he is very knowledgeable and helpful
If I could give Douglas 6 stars, I would. He is knowledgeable, and really cares. Did a great job and made recommendations. Not his first time here and always detail oriented.
Anthony Pena was great, he did great work, very fast on fixing our 1 year old water heater union valve and was very nice
Highly recommended 5 stars all day

Thanks, guys!
Needed an install of a faucet and toilet. The team arrived on time and was able to provide me an overview of what needed to be done and transparency with the pricing. Wrapped it up in a shirt while and looks great!
Great service. On time and reasonably priced. Came out to double check on an issue that was still unresolved at no charge.
I got Steve and his colleague from GEM Plumbing to work on my heat pump. I would highly suggest them. They were very patient with all of the explanations of what was wrong and made sure I understood everything. They also gave me a rundown on changing air filters and educated me on all of the necessary information. Overall, I had a pleasant experience. The entire process, including diagnostics and problem resolution, took less than two hours.
James called explaining he was at our cottage for AC maintenance and checking on our new system.
Quick, easy, efficient and clean and Courteous.
Brody and his assistant did an amazing job fixing out central air. Both were friendly and super knowledgeable. GEM got us a small day appointment. If your looking for a company that has your back, look no further.
Davontay did an amazing job going through my A/C system and Nest thermostat to make sure it is properly running. He was very thorough and explained things clearly

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.
