I am very pleased with ALex's service. He is knowledgeable and polite.
The technician arrived. He came in and diagnosed the problem with my ductless system. He was able to get my system functioning, even though he didn’t have the pot needed to be replaced so temporarily we can run the system as it is he did he did his job by diagnosing the issue and doing a temporary fix?
I called GEM for a weekend, short notice pipe repair, and everyone was great from Hendry who I spoke to on the phone, to the two technicians Alec and Danny. They worked quickly, communicated clearly, and worked with me to come up with a solution I was happy with the price and result of. I would definitely call them in the future when things pop up.
Can’t say enough good things about Gem Plumbing and Thomas in particular. I easily got a came day appointment, Thomas the tech was here in the agreed upon window, provided 2 alternative estimates and once we selected, he completed the job right away – no need to make another appointment and come back another day. Great work, and even better service!
Chris A diagnosed my tankless water heater problem and repaired it quickly and efficiently. He answered all my questions with clear answers and was very helpful in alleviating any of my concerns. He gave excellent service!

William and Mark were excellent! They explained everything that they were doing and included us through the whole process. Would recommend them highly.
Very prompt and professional service!
The service provided by Mark and his partner was incredible. They took the time to explain all details of the situation and even helped make a call to a remediation company. They cleaned up after themselves and were very easy to discuss the repair process with.
Always a pleasure, professional expert service. Solving any problem simple or difficult!
Came even late at night to make sure we had working air conditioning
The team that installed the unit (Luis Herrera Mezquita Et al) was very professional and explained things thoroughly. I would highly recommend them.
Great customer service and understanding with us, and answered all our questions.

Thank you GEM
Was very impressed with Gems
Tech who was able to repair our AC units during our first real heat wave.
Hope to do business with Gem at our new home soon
Thomas from GEM came out today for my annual air-conditioning service, and I couldn’t be more impressed. He performed a thorough inspection, topped off all the necessary fluids, checked and adjusted my filters, and made sure everything was running smoothly and efficiently.

What really went above and beyond was that he noticed a hornets’ nest growing next to my air-conditioning unit and took care of it for me on the spot. That was something I hadn’t even realized needed attention, and it saved me from a potentially unpleasant surprise later on!

Thomas was professional, knowledgeable, and incredibly helpful throughout the entire visit. It’s rare to find someone who pays such close attention to the details and takes such pride in their work. GEM is fortunate to have him on their team. Thank you, Thomas, for the outstanding service!
Technicians were highly qualified. Very knowledgeable and professional. Respectful towards me and my home. Completed installation with in timeframe and cleaned up the areas they worked in. My issue is with whoever issued the system’s equipment. After 6 hours of working the technicians discovered they had been given the wrong system until! Resulting in them having to return for another 6 hour work day! This resulted in an additional day of inconvenience for myself and my family. No one from the Gem administration/management team has contacted me to apologize or offer reconciliation. I am happy with the product and the performance of the technical staff. But not with the treatment from management.
We had a tree branch fall and take out all of our electric equipment. GEM answered immediately and got someone out quickly. Mike Alberto got the job done quickly and explained everything as he went along. Great job!
