Paul V from Carmine’s, arrived promptly and was very professional, knowledgeable, patient and has a great demeanor. He changed the control board of my HAVAC unit, and gave me great suggestions of the usage of it. Paul is very sincere and you can see his dedication to his work. I would definitely recommend Carmines and Paul V for any of your HAVAC needs.
Friendly, explained what was being done and what to watch out for.
Great job by David
Victor is the best. He fixed our clogged pipes and came out right away
Great service ! They were on time, respectful and took care of business quickly and efficiently
Lost our well water tank, great job with replacement. While here had them replace kitchen faucet and garbage disposal also. Will use GEM from now on!
Eric and Steve are great. Got the job done fast. Cleaned up. Terrific work.
We had 2 very old direct vent gas wall heaters replaced. Evan and Steve are the best. They explained everything and did a awesome job for never putting in these Rianni heaters . Kept me informed and answered all my questions and eased my concerns . Couldn't of asked for two better guys. The electrician and his assistant were outstanding with the fact the house was
built in 1925 with older wiring . Chen and his assistant installed 2 dedicated circuit for both heaters to run on and it works out great as now my air conditioner will run on the dedicated circuit this summer. Would recommend all of them for future heating needs .
We had the bathroom one downsized to a smaller unit with no issue what so ever even with them having to remove the bigger one they had put in they were happy to accommodate the issue
They are sweet, knowledgeable and quick. Thank you guys for an excellent job done, I appreciate it.
The gem guys could not have been any nicer. We had to leave and trusted them in our home alone.
Very professional and thorough. Serviced not only my mini-split but my air conditioner and checked my furnace and changed it's filter. Very happy.
The folks at Carmine's/GEM always do a great job👍 Anthony Pena did a great job checking the gas dryer connection and valve. Made sure everything was working properly and that there were no leaks.
Joan Martinez came to my house on an emergency call when my furnace/boiler broke down at 1 am. He diagnosed the issues and unfortunately I needed a new system. GEM installed the new system over the next two days. Everyone on the crew was excellent. I signed up for GEM’s maintenance program because if I had previously it would have prolonged the life of my furnace/boiler. Today Joan Martinez returned to do routine maintenance on my mini splits. He was very thorough and made sure the units are ready for the summer season. I highly recommend and trust Joan Martinez for any job.
Brody you were terrific! So knowledgeable. Appreciate that he showed what might be needed in the future. Thanks Gem Plumbing for sending him. Thanks for coming out Steve and servicing air conditioning and cleaning splits replacing filters as well as making sure it all works. I appreciate the prompt and friendly service. Sincerely I've

Very good experience. Quality work, and professional.
David was very thorough and patient. He was determined to get us a resolution and even ensured he taught us on best practices and troubleshooting techniques.
Although, we had to drop a lot of money today. We are very appreciative of David Santiago and Colin D. David explained everything that was wrong with our system. Even tried to find a way to fix the disaster. Even though we both knew, it wasn't worth it. That's where Colin come in and broke the heart breaking news but helped us find options and worked with us. With that we are VERY thankful for you both! GEM has a life long customer. Thanks guys.
Alex did a great job and most importantly, gained the confidence of my wife. Not an insignificant accomplishment in the middle of major repairs that required shutting off water and not flushing toilets, etc. Thanks Alex!

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.
