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.

Fast response, constant communication, professional service, and fair pricing. Literally couldn’t ask for a better experience.
Tristan was very professional and knowledgable!
Got a problem with your well pump not working? Not a problem! Call Gem plumbing & heating services. Our 100’ deep well finally lived out its life and stopped working. Not a pleasant experience when suddenly you have to get water somewhere and start filling up buckets. I called on Saturday and they came by within a few hours. They checked the pressure tank first then the well. They came back Monday and installed the new pump. I couldn’t have asked for better service! They were there when I needed them!

Incredible service. Needed emergency plumbing help, she arrived and got the job done. Would highly recommend this plumber..
Scheduling was poor but the service was good.
No answer as I got no formal ask.

However, he was, on time, polite, clean, efficient and answered all my questions ( I’m a retired engineer). I would ask for him on future appropriate jobs. Be good to him. He is of great value to you.
Vincent was terrific! He was able to identify the problem that caused a flood in my basement right away and fixed it.
Moreover he is so calm and personable. Took the time to teach me and lable the shut offs and showed genuine concern.
David is awesome!
We have used Gem several times for plumbing and HVAC. They have always been courteous, professional, and thorough. We will continue to use them for any plumbing needs in the future.
The plumber arrived on time,looked at the problem,told what he would be doing to fix it.(I had a leak in the main pipe leading from the toilet to the exit pipe)That had to be replaced,the toilet drained,a new line through the wall upstairs.A perfect clean up.Christopher was polite.
Always have a positive experience with GEM plumbing and heating whenever we need them. They are prompt, professional and competent. Totally recommend their services.
Very nice people,knowledgeable.
Fixed the problem quickly.
I had a very slow leak under sink. Very professional nice service guys came same day to diagnose the problem. It turned out to be the garbage disposal. Their estimate was $700 for the labor. My other quote for same work from a licensed plumber was $350. Shame I’m out $149 for the service call. I’m still giving 5 stars because I’m sure that this company does 5 star work – but price for the labor for this particular job was twice as much as elsewhere.
Polite, professional and work was completed fast!
Always reliable and courteous service! We have relied on GEM for regular maintenance, repair services, plumbing, new HVAC installation, and even shower installation. We feel we can cou t on GEM to be there when we need them and always perform great work.
The team I had was professional & friendly. Answered any questions I had along with explaining options.
Great job Anthony

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.
