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.
The team was:

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!

FAQ
Do you provide same-day AC repair in Lexington?
Yes. GEM offers same-day air conditioning repair throughout Lexington, from homes near the Minuteman Bikeway to properties along Marrett Road.
Can you work on AC in Lexington’s historic homes?
Absolutely. Many Lexington homes date back generations, with original construction that wasn’t designed for central cooling. We’re experienced with the ductwork challenges, insulation limitations, and layout constraints that come with retrofitting AC in historic properties.
What energy rebates are available to Lexington homeowners?
As a Mass Save® partner, GEM helps Lexington residents access rebates on qualifying high-efficiency equipment and system upgrades. We handle the paperwork so you get every dollar you’re eligible for.
Why does my wooded Lexington lot stay humid?
Lexington’s mature tree canopy traps moisture, particularly in neighborhoods with heavy oak and maple coverage. If your home feels clammy even when the AC runs, you may have undersized equipment, drainage problems with your condensate line, or your system may benefit from whole-home dehumidification.
How often should Lexington homeowners schedule AC maintenance?
Annual maintenance is recommended for all Lexington homes. Systems cooling older construction or working against humidity from wooded lots benefit especially from regular professional tune-ups that keep efficiency high and catch wear before it becomes failure.
