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 PVCโ€”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.
Nateโ€™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 hadnโ€™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 donโ€™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!

Signs Your Portsmouth Home Needs a New AC

Even the best air conditioners don’t last forever. If your system is struggling to keep up during Portsmouth’s humid summers, it may be time to consider a replacement.

Knowing the warning signs early can save you from costly repairs and uncomfortable days without cooling. Here’s when we recommend considering a new AC installation.

When your system turns on and begins a new cycle, you may hear a gentle hum. That’s normal and doesn’t signal issues. When you start noticing grinding, rattling, or musty smells in your Portsmouth home, though, it’s often a sign that something isn’t working as it should. Properties near Mount Hope Bay and the Sakonnet River face higher humidity that can accelerate mold growth inside units. These issues can point to worn components, poor airflow, or even mold inside the unit. If your AC is getting noisier with each cycle, especially in Common Fence Point or Island Park where moisture levels run higher, it’s likely time to consider replacing it with a newer, quieter, and more efficient model.

Hot and cold spots in your home often signal that your AC is no longer distributing air evenly. Whether it’s too warm upstairs in your Portsmouth colonial or too cold in your living room, uneven temperatures mean your system may be nearing the end of its lifespan. Aquidneck Island’s mix of historic homes and newer construction makes this problem especially common as aging systems struggle to push cooled air to upper floors. When certain rooms feel warmer than others or your system runs nonstop without keeping up in Portsmouth, it’s a clear sign your air conditioner is losing efficiency. Over time, this leads to higher energy bills and reduced comfort, making a new AC installation the best long-term solution.

Most air conditioners last about 12 years with proper maintenance. Systems in Portsmouth’s coastal environment often wear out even faster due to salt air exposure that accelerates corrosion. As they age, they naturally become less effective and efficient. Modern systems are built with advanced technology that improves cooling performance while using less power. Replacing an outdated unit in Portsmouth not only enhances comfort and efficiency but also gives you the reliability and peace of mind that comes with a brand-new, warranty-backed system.

If your electric bills are climbing even though your usage hasn’t changed, your system could be losing efficiency in Portsmouth’s humid climate. Older units have to work harder to maintain comfortable temperatures, especially during Rhode Island’s humid summer stretches when the air feels heavy and sticky near the bay. New air conditioning systems are designed to operate far more efficiently, using less energy to deliver better cooling performance. Upgrading your AC in Portsmouth can significantly lower monthly utility bills while providing more consistent comfort and peace of mind for years to come.

Cooling System Options for Portsmouth Homes

Every home in Portsmouth is unique, and GEM offers a range of energy-efficient cooling systems to fit your space, comfort goals, and budget.

No matter which system you choose, you’ll get expert guidance, professional installation, and lasting reliability from Rhode Island’s most trusted HVAC team.

Ideal for whole-home comfort, central air systems keep every room evenly cool and comfortable. GEM installs high-efficiency central air conditioners that integrate seamlessly with your existing ductwork, helping you enjoy quiet operation, lower energy bills, and consistent performance. For reliable air conditioning in Portsmouth, they’re perfect for the area’s colonials and single-family homes, delivering reliable cooling throughout your entire space.

Looking for both heating and cooling in one efficient system? Heat pumps are a smart, eco-friendly choice for Rhode Island’s climate. They move heat in and out of your home rather than generating it, offering year-round comfort and significant energy savings. As a Rhode Island Energy partner, GEM helps you access available rebates and incentives to make upgrading more affordable.

For homes without existing ductwork or rooms that never seem to stay cool, ductless mini-splits provide a flexible solution. These sleek, wall-mounted units let you control the temperature in individual rooms, giving you comfort where you need it most. They’re perfect for Portsmouth homes with finished attics, sunrooms, or additions where running new ducts isn’t practical.
