The folks at Carmine's always do a great job๐Ÿ‘ Tim is a great plumber, explains things, and provides options.
Very professional service. They came the same day and solved the problem quickly and completely. I would definitely use Gem again if I needed plumbing work.
I called GEM because I wanted my ductless ACโ€™s checked to see if they needed any service. Christopher Cennamo came and examined both units and said they were functioning properly but needed a cleaning to remove mold and dirt. The large unit is at the top of a stairwell so access requires a tall ladder. Christopher made the appointment to return to do the cleaning and also to determine why the larger unit was tilting off the wall. He returned today and determined that the larger unitโ€™s mounting bracket was only attached to drywall and not a wooden stud. He and Brody Lott secured the mounting bracket to a stud, ensuring the unit is now securely on the wall. A thorough cleaning of both units was completed including removal of a mouse nest. Christopher told me how to use steel wool in the outside pipe cover to prevent mice from entering which I promptly did. Christopher Cennamo was very professional, thorough, knowledgeable and explained everything. The cleaning was expensive but worth it. Plus he didnโ€™t charge extra to repair the faulty mounting issue because GEM had done the initial install and not done it properly. I highly recommend Christopher Cennamo for any of your heating and cooling jobs.
Took some time to get here but, The awesome technicians, were friendly and work hard to minimize costs and make sure the customer is satisfied. Surely a company you can count on.
Excellent service
Paul was knowledgeable, very friendly and described the repair process, in detail, to my satisfaction
Technicians did a fantastic job, neat, quick and clean
Overpriced for a 90 minute job
Eric and his co worker were on time, provided great service and took the time to explain the work required. Highly recommend for your plumbing and water filtration repairs and maintenance needs. Exceeded expectations.
Jordan was awesome! He came on time and was very friendly and helpful.
Brandon is my all time favorite! Canโ€™t say enough, and Max is such a great kid and so pleasant! They both are great! Good workers! Blessings to both of them ๐Ÿ’™
Brandon and Max did a wonderful job today and as always, very polite and professional in the way they go about their job.
The technicians did a great job, very knowledgeable, courteous, explain what they were doing in detail, and very respectful. Definitely deserve 5 stars!!
He showed up on time, very polite and professional. Gave full and understandable explanation of what the problem and scheduled the fix for the next morning. While it was super expensive, it seems on par with others in the area for what needed to be done.
A very thorough and professional job. David Salvatore demonstrated great expertise when answering all my questions.
The best company I have ever dealt with congratulations on being the best Adam Baron
Richard came to my home to check my heater for a diagnosis. He was very friendly and knowledgeable. He took the time to explain what was going on and answered all my questions. Thank you Richard
Very professional, cleaned up after each day, seamless process
Great experience from start to finish. The mini split system and tankless hot water heater were installed professionally, and everything works perfectly. The team provided excellent service and had a quick, responsive communication throughout. Highly recommend.
Mason did an excellent job replacing my hot water heater. He was knowledgeable, professional, and personable. I was extremely happy with his service.
Anthony P did an excellent job. Very professional and respectful. Went above and beyond the call of duty for sure. Thanks
I would again highly recommend Gem!
Douglas and Christopher came installed new insulation on the outside lines, cleaned the whole system And removed mold from the units and added a UV light Air scrubber in the attic. Nice job done by all.
Eric did a great job testing our water and suggesting appropriate solutions to our problems
Brian installed electric outlets and replaced light fixtures. Took the time to do it right and pointed out any difficulties with a proposal for the way to oroceed
Great Service!
First time using Carmineโ€™s or any home service and they were great. We first got a free estimate and were able to ask questions and get reliable answers on the water heater . Would totally use in the future.
Joseph from GEM did an excellent job with our semi annual HVAC maintenance. He explained exactly what he did and was thorough & efficient. Additionally he was friendly & professional. We are very satisfied with GEM overall.
So far, GEM Plumbing & Heating has been very helpful to us. We've had the maintenance membership for a little more than a year, and they come twice a year to service our heat pump, minisplits and tankless water heater. We're happy with their service, and their technicians are usually very friendly, respectful and patience with us, taking time to explain maintenance aspects of our equipment, as well as, giving us usage and maintenance tips.
UPDATE: it's been three years of the maintenance service and again, nothing but praises for GEM. Keep up the goo work!
