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 work on a variety of household electrical needs. Service techs were professional, friendly, and all work done to high standards!
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.
Excellent service with clear explanation. On time, friendly professional communication. Issues resolved with creativity!
Cory was very knowledgeable and respectful.
The technical aspects of the job he explained so I could understand.

I had a great experience with my recent HVAC appointment. David the technician was punctual, polite, and very thorough while performing the annual maintenance of both our heating and cooling systems. He explained what was doing, reviewed the results of the tests that were done and provided estimates for potential future component replacement.

Hands down the best service, communication is top notch. My Ac and furnace needed to be replaced and I must say Alecs Reyes and team were amazing, polite and professional and informative every step of the way. I highly recommend Gem.

Efficient professional and quick service excellent!! Thank you Eric
Devontay Vaz and his colleague did an excellent job servicing our scheduled maintenance on our Heating and Cooling Mini Split system which is part of our Maintenance Plan. They took the time to explain the process from start to finish. They also made sure to explain the future unit maintenance after the summer season, which we found VERY helpful. We have been members of Gem Heating and Plumbing for years now. As always, the technicians were polite, professional, and knowledgeable about their work. With life being busy, Gem always call us as a reminder to make these scheduled appointments. Thank you, Gem Plumbing!!

Frequently Asked Questions

Why isn’t my air conditioner blowing cold air?

This could be caused by anything from low refrigerant and dirty filters to mechanical issues or electrical faults. A professional inspection is the best way to find and fix the problem quickly.

Why does my AC keep turning on and off?

Frequent cycling, or “short cycling,” often indicates an issue with airflow, thermostat calibration, or system sizing. It’s important to address this early to prevent damage and higher energy bills.

What should I do if my AC stops working suddenly?

Check your thermostat settings, air filter, and circuit breaker first. If the issue isn’t obvious, contact GEM for fast, reliable service—we offer same-day repairs to restore your comfort.

Why is my air conditioner making strange noises?

Unusual sounds like banging, buzzing, or rattling typically mean something inside your unit is loose or worn out. Have it checked right away to prevent further damage or system failure.

How long does an AC repair usually take?

Most repairs can be completed in just a few hours, depending on the issue. GEM’s fully stocked trucks and experienced technicians allow us to complete most fixes in a single visit.
