Worcester, MA Water Heater Replacement

Showed up right as scheduled and expedited repairs immediately!!!! Tech was extremely knowledgeable, efficient and awesome! 5 Stahs all around!

Nick was extremely helpful and honest. I hope Nick will assist during GEMs next visit.

They just came for an estimate but they were on time, very friendly and respectful. They answered all my questions. I didn’t pay for the estimate but I had to put something at the bottom. Thank you

Aiden Bradley-Main of GEM HVAC was a consummate professional. He communicated clearly, instilled confidence, and got the job done well. He gets my highest recommendation.

Efficient, on time, good diagnosticians, affable staff… but costly!

David Salvatore was prompt, professional, and pleasant. He diagnosed my air conditioning issue and solved it quickly on the same day!

GEM staff rxceedrd my expectations in ensuring that we were "completely" satisfied with their work. I am extremely satisfied with both their communication as well as their work. Job well done GEM!!!

Douglas was friendly, polite and knowledgeable. He made a few suggestions for my hvac and was going to email some updated parts I should consider to add and install. I have not yet received the email. Overall he did a good job.

Great having GEM here for Installation of heating system – From start to finish : With Tim and Rob making the plans, with Jacob and Eric and Gennarro taking care of all the plumbing and figuring things out in our old house – very professional, got the job done in a helpful and timely and efficient way: helping me feel ready this year well ahead of the heating season, Thank you Gem!

Abraham was very professional and finished the job same day even after encountering some obstacles to do it. He answered all my questions and was very helpful

Nicole Tradd was fantastic today. I had a leak in a copper pipe (on a Sat) and Nicole came out to house and had everything fixed in no time at all. Very satisfied with her work. Thank you.

Service was quick and complete and very fairly priced.

Great communicator. Knowledgeable.

Aaron Neal was very professional and thorough. He diagnosed the problem, explained it to us, and followed with ordering the part to return and install. I highly recommend Aaron for his knowledge and customer service.
He worked in the job from 8 – 10 pm to restore our air conditioning during the recent heat wave.

Excellent service in every respect: starting with the salesperson, Peter Dallas; Sean, the installation coordinator; and, of course, the installers Joe & Cristar!!
Pete was extremely professional, friendly, understanding and very flexible when negotiating the final price.
After 28 years of using a Lennox central heating and air conditioning system, we decided was time to get new systems and we went with Carrier this time, a highly respected brand too backed by GEM Plumbing as a certified provider. Both the sales process and the speed of the installation were incredibly efficient. We spoke with Peter on a Tuesday morning , and by 3:00 p.m. on Friday of same week the installation was complete. We were lucky enough to have Joe Medeiros and Cristar Fig from GEM as our technicians!
Let me tell you, this duo is exceptional! They are very young but possess extensive knowledge and a fantastic attitude. I was truly impressed by their technical work and their courtesy. These two technicians are a great asset to GEM and WE would love them to be recognized! We are very happy at home; the air conditioning system works wonderfully! And We can’t wait to use this coming winter our new furnace too!
Thanks to Peter, Sean, Joe, and Cristar for their amazing job!!
Sincerely
Mary

ALecs Reyes was the best!!! Extremely knowledgeable and professional. He turned our terrible experience with our last contractor into a positive outcome . I will add that he was a fantastic mentor to the helper he brought along today. ALecs is the kind of employee every business owner searches for….Good luck in your career at Gem Alec’s!!!

Great service and very personable rep. I am very happy that I contacted GEM.

Nicole was great. Super nice, super helpful and quick. I wish I was as effusive about the exorbitant prices that GEM charges.

Super great people and service!

We had been struggling to find a plumber for a month! GEM was available and took us in immediately when others were ignoring our calls! We now have hot water again. I can shower in peace.

Richard was on schedule and very honest and transparent regarding the failed part and freely answered questions about the HVAC system overall.

Update!
July 2026 — I just had Tim F from GEM ground my 21' above ground pool. Service was quick & excellent as usual! Highly recommend GEM electricians, plumbing & HVAC! They're fantastic!

June 2026 — Just had John P from GEM provide maintenance on my central AC unit. He was fantastic! Explained everything and performed his work efficiently with great communication andcrespect for my home! He was just great! I appreciate being able to get an appt so quickly with GEM. It's so helpful to be able to schedule appointments around my availability and as a FT worker who commutes via rail, I value that scheduling flexibility. Their work is exceptional. I highly recommend GEM!

The GEM plumbers were fantastic. They hooked up a new spigot and a back flow preventer for the drip irrigation system I will have installed soon. They explained everything, they were fast and respected my home during the job. I highly recommend GEM for your next plumbing repair or upgrade.
Today Nicole from GEM extended the pipe and added a female adapter for the irrigation system. She was speedy and fantastic!

Timely, helpful, and knowledgable! Took time to explain things thoroughly

Bob was on time, did a good job and was very helpful.

Problem was taken care of, and further service was recommended for our consideration. Nick was friendly and explained things really well. Overall would highly recommend thank you.
