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!

Warning Signs It’s Time for AC Replacement in Marion

Your air conditioner provides clear signals when replacement makes more sense than another repair.

These warning signs tell you it’s time to consider new air conditioning installation in Marion.

Repeat service visits get expensive fast, and they never solve the real problem. Aging cooling systems break in cascading ways – fix one part and another fails shortly after. You’re essentially renting a broken system instead of owning reliable equipment. Installing new air conditioning in Marion stops this money drain and gives you dependable performance throughout South Coast summers.

Hot zones in certain rooms while others feel fine means your system’s lost its ability to distribute cooled air properly. These temperature variations waste energy and make portions of your home unpleasant to occupy during summer heat. Throughout Marion properties, uneven performance typically signals equipment that can’t keep up anymore. Professional air conditioning installation in Marion restores consistent comfort to all living spaces.

Cooling systems generally function well for 12 to 18 years before natural decline sets in. Past this threshold, reliability drops and operating costs climb as aging components struggle. Modern units deliver far superior efficiency compared to equipment built over a decade ago. When your AC reaches 15 years, replacement through air conditioning installation in Marion typically proves more economical than continued maintenance of outdated technology.

Notice your electric costs increasing steadily despite no changes in AC usage? Declining efficiency causes this gradual upward trend. Worn components force your system to work harder while accomplishing less, driving up consumption month after month. New air conditioning installation in Marion reduces energy use substantially while providing better cooling performance for your Plymouth County home.
