What Our Customers Are Saying
100% Satisfaction Guarantee
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.
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.

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 You Need a New AC System
Understanding when your air conditioner needs replacement helps you avoid emergency failures during Wellesley’s warmest weather.
Pay attention to these indicators that it’s time to consider a new air conditioning installation.
Water pooling around your indoor unit or excessive moisture in your home indicates serious drainage or refrigerant issues. These problems don’t just affect performance; they can damage your property and create conditions for mold growth. When your AC produces persistent moisture problems, the underlying issues typically worsen over time. Replacing the system with modern equipment solves the problem completely and protects your home.
When air barely flows through your vents despite the system running, something has failed within your AC. Weak airflow makes cooling ineffective and forces your system to operate continuously without achieving comfortable temperatures. This poor performance usually indicates compressor failure or ductwork problems that worsen with continued use. A new installation designed for your home’s requirements restores proper airflow and consistent comfort.
Air conditioners generally function well for 12 to 16 years before efficiency naturally declines. Once your system reaches this age range, replacement usually makes better financial sense than ongoing repairs. Today’s AC technology provides superior cooling while using significantly less energy. Installing a new system improves both comfort and efficiency while giving you equipment backed by manufacturer warranties.
Rising electric bills despite unchanged cooling habits signal declining efficiency. Aging systems consume more power to maintain comfortable temperatures, especially during peak summer conditions. Modern air conditioning systems are engineered to operate far more efficiently, using substantially less energy while delivering better cooling performance. Upgrading typically lowers monthly expenses while improving overall home comfort.
