I was not a service call. It’s just a yearly check up on the air conditioner. I did not meet Thomas personally, but my wife said he was very nice man. you must’ve needed a garden hose for something. I noticed it was moved, but it was wrapped very nicely and put back where where he found it. I appreciate that. overall, we were very pleased with the service. Thank you.
Outstanding
Extremely happy
fantastic technician and service!
Great company to work with! Good communication, availability and the plumbers who came to pull a gas line were professional. Would definitely use their services again.
We received great service and happy with the results!
Tony and Kevin were great, very professional and very knowledgeable- they listened to what I thought was going on, started there and quickly solved the A/C airflow issue. In this day and age and how expensive everything seems to be it was refreshing that Tony seemed very aware of pricing and as a result of their experience and efficiency make the bill very reasonable
Aaron was knowledgeable and extremely helpful
Technicians Steve Gray and Chase were Outstanding in every detail from presentation to knowledge , expertise and commitment to resolving my problem. I am a very please customer and I just need to say Steve and Chase represent your company extremely well. I will continue to be a very loyal customer. Thank you
Xavier and Mike did an excellent job.
We were very happy with the Service! Jacob and his “understudy” showed a very professional and efficient service. Jacob seem to be very experienced, and knowledgeable, and can think outside of the box. For over 20 years every time we had the boiler serviced, louvre was recommended as a solution for the low air supply.. Jacob saw the unused 4 inch dryer duck which is already in place and with minor modification can provide more air, which I thought was a brilliant idea. Highly recommend this team to anyone!
Nicholas from GEM was very informative and fixed our problems and gave good advice. Thank you!
Generator maintenance. Excellent in all respects.
Douglas is terrific!
Orlando and Marcello are true superstars of your business! Polite, very quick at helping me fix my problem with my Plumbing. The whole process from start to finish was handled beautifully thank you so much for making a stressful situation so much easier!

Excellent service! Gem Plumbing was professional, responsive, and arrived on time. They quickly identified the issue with the roof drain pipe, clearly explained the repair, and completed the work efficiently. The quality of the workmanship was excellent, and everything was left clean when the job was finished. I would definitely recommend them to anyone looking for a reliable plumber.
