Leak in kitchen. Technician was quick and professional. I’ve used gem in the past and have always had a good experience.

Nate came out first thing in the morning to help with my clogged sewer main. He was very professional and kind. He explained everything with no difficulty and offered multiple cost-tiered options. Mainly whether we would utilize a camera in the process of snaking the main. I appreciated being offered the option. We went with the camera process. So we could fully diagnose the issue, and determine if this would be a recurring problem.
We found roots growing in an old, 2-foot, cast-iron section of my main drainage pipe.
He used a blade attachment and cleared the obstruction to the best of his ability. Then left me with a quote to have the 2-foot section of cast iron replaced with PVC—which is only a small section that penetrated the foundation of my home.
I was very happy with the service, and most importantly the transparent approach which allowed me to make informed decisions.
Nate’s customer service skills were out of this world. I advise GEM Plumbing to invest in this young man.

Incredible company.
I had two whole house central AC units replaced (19 yrs old) and their team and other parts of the company (Plumbling, electrical, etc.) worked together to do an unbelieable installation in very hot conditions. My hats off to your company and we are so impressed that I contracted GEM to install a whole house 25kw generator.

I was able to schedule an appointment for the next day. The technician was great. Chris went over everything that needed to be done and explained it clearly. Very professional. He was also able to offer a discount and waived the fee for the service call. When I reviewed the bill that night, there was an error and the fee hadn’t been waived. When I called Gem the next day, they saw the error and immediately corrected it. Said the refund would be put on my credit card. Very happy with the service.

I am very happy with my well water pump service. David Chapman and his associate were professional, friendly and respectful. David showed me how to change my filter for which I am truly grateful.
It was super easy booking online The next day the dispatcher, (unfortunately I don’t know her name) called to offer an earlier appointment. She was very polite and kind.
My whole transaction was smooth and pleasant from start to finish!

How to Know When You Need a New Furnace Installed

Sometimes it’s obvious you need a new furnace, but other times the signs are harder to spot.

Your heating bills and how well your furnace runs go hand in hand. When your furnace starts losing efficiency, it uses more energy just to keep your house at the temperature you want, and your monthly costs climb. For most East Dennis homeowners, rising bills are the first sign their heating system is getting close to the end.

Most furnaces run for 15 to 20 years if you keep up with maintenance. Once yours crosses that age, it starts breaking down more often and doesn’t heat as well. Getting a new furnace installed can boost your comfort, cut your costs, and give you peace of mind for the next couple decades. Whether you’ve got a gas or oil furnace in East Dennis, upgrading to modern equipment makes sense.

If your furnace runs in short bursts, turning on and off constantly, it’s working too hard to maintain your temperature. This cycling wastes energy and wears out the parts inside faster. For a lot of East Dennis homes, when this starts happening, it’s time for a new furnace.

When your furnace won’t turn on at all, that’s one of the clearest signs something major is wrong. Sure, sometimes it’s just a thermostat issue or a tripped breaker, but if your system is old or failing, it might be past the point of repair. When you need a new furnace in East Dennis, GEM is ready to help.

We Install All Types of Furnaces in East Dennis

Every home is different. Some run on natural gas, others use oil, and some are all-electric.

No matter what your home needs, we install a full range of furnaces that deliver steady, reliable heat all winter long. Here’s what we install in East Dennis:

Gas furnaces heat up fast and run efficiently, making them one of the most reliable options out there. We install gas furnaces in East Dennis homes to keep you warm through even the coldest Cape Cod winters. These systems are energy-efficient, affordable to run, and great at keeping your whole house at a steady temperature.

If your home doesn’t have natural gas service, an oil furnace is a solid choice that delivers strong, consistent heat even when it’s freezing outside. We install high-efficiency oil furnaces built to give you maximum warmth without burning through fuel. Our techs make sure every installation is done carefully and correctly, so East Dennis homeowners get a heating system that lasts.

Electric furnaces are a smart pick if you want something safe and low-maintenance. They heat your home evenly and steadily without needing gas or oil, which works well when electricity is your main energy source. GEM installs electric furnaces that run quietly, work efficiently, and keep you comfortable all winter.

Solar furnaces tap into renewable energy to heat your home cleanly and sustainably. These systems lower your monthly energy bills and reduce your environmental impact at the same time. GEM helps East Dennis homeowners go solar with professional installation and ongoing support, giving you efficient, eco-friendly heating for years to come.

Whatever type of furnace you’ve got, GEM can help. We also install upflow, downflow, and horizontal furnaces in East Dennis.

  • Horizontal Furnaces: For smaller spaces, horizontal furnaces are installed on their side, perfect for attics, crawl spaces, or tight basements.
  • Downflow Furnaces: Suitable for attics or other high placements, downflow models pull in air from above, distributing it downwards.
  • Horizontal Furnaces: For smaller spaces, horizontal furnaces are installed on their side, perfect for attics, crawl spaces, or tight basements.
