Leicester, MA Water Heater Replacement

We did a maintenance request for our heating system. Christian and Joie were very pleasant and gave us the results based on their analysis of the system. They arrived within the time frame and completed the process in about 30 minutes.

Showed up when expected. So kind and courteous and explained everything to me that would need to be done for my plumbing issue. Would highly recommend GEM.

Erickson was great! Explained conditions of units and recommendations for upkeep!

The service was good.Aiden was very good. It’s just they said they were on there way 2hrs and30 min they finally arrived. Waited all afternoon

The 2 service men were on time, assessed the problem, diagnosed the issue, came up with a plan and offered several solutions for fixing our mini split. They took pictures, tried clearing out mice debris , attempted to get the outside machine to work ( apex 2 hours) Alas a no go, so we decided to scrap it and go with baseboard heater for the room over the garage. Up front information and pricing , no nonsense. Affable techs and so far great service.

I would recommend Nathan and GEM in the event of a plumbing emergency and or issue

No repair was performed at this time I had to pay a diagnostic fee.

Eaven though I was very specific what toilet I wanted they put the wrong one in.

Absolutely incredible and fast service from Nicole T! Our upstairs toilet began leaking Saturday night and by noon on Monday we had a new toilet! Nicole was super informative and walked us through our different options every step of the way. She made an otherwise stressful situation so much easier!

I had a great experience with Gem Plumbing and Heating. It was great starting from the initial phone conversation and continued with Brian Ciaschini. Brian was an excellent electrician, he was cordial, informative and helpful. Brian made sure everything was working perfectly! I would recommend them and I will use them again.

Friendly, efficient working time, knowledgable!

Excellent as always

Exceptional service! Knowledgeable, and they left with giving me a lot of insight on boilers and options we had. They left and we felt much better.

Exceptional service from GEM. Douglass is absolutely the best !!! … will use them again. Thank You!

Workers were polite and knowledgeable. They diagnosed the problem right away. And we're able to repair it same day.

Rainey was excellent . He explained why my system failed and explained what a new system would cost . We agreed to replace our furnace which was 24 years old . Rainey and Pedro showed up at 8 and before 4 I had a new furnace installed and the old one hauled away .Easily explained all the process , he was excellent

the price put me in sticker shock …..but the work was exceptional. they did a great job and explained to me what they did.

Seemed very knowledgeable and very informative. Friendly service as well.

I was thoroughly impressed with the superb HVAC maintenance service I received from David Santiago and trainee, Kevin today! Before David and Kevin arrived I was very disappointed with having had my original service date rescheduled to what I thought were spurious reasons? In fact David and Kevin arrived after the designated rescheduled date and time today. GEM's communication was excellent throughout and their people seemed genuine and concerned. When David and Kevin arrived it turned the whole situation around. They could not have been more professional and knowledgable! I am now firmly committed to GEM and their Home Comfort maintenance program.

Professional, informative, and reliable!

We just had our heating system replaced. We went from forced hot water system to a central heating and air conditioning system done by GEM plumbing and heating company We had Omar and Michael work in our home for 5 days they installed all the ductwork, the furnace and the condenser. These guys were very professional, kind, clean and informative throughout the whole install every day they explaind what they did and what is the expectation for the next day. Today was the last day they walked me through the whole system, how to change the filter how to operate the new thermostat and what to look for when things are not working properly. I say thank you to the whole team from planing to done, all went great to expectations

Erickson was great. Efficient, friendly and through. Very professional
