Both service calls to my house were with Nick, and I can't say enough good things about him. He's professional, courteous, communicative, and thorough.

great guy! vaery talented and professional
Joseph (Junior) from GEM Plumbing & Heating came out to do a check on our HVAC system for this season. He was very thorough, knowledgeable, and honest. Our system is in great shape after 16 years. Thank you Joe!!! We were on a contract plan, which was very reasonable, so we paid nothing at the time of service.
Our tech was Joseph (junior), Incredible experience came out the same day.Billed me for the service. Exceptional diagnostics, developed a number of options to fix the problem. We called four other places.First three never showed one showed and walked away, without figuring anything out. Our A/C has been out for 6 wks waiting for people to not show up. YOU ABSOLUTELY MUST CALL GEM FIRST
GEM responded very quickly. I was out of state when my tenant called stating the A/c system wasn't working. I called GEM to see if they would be willing to help me. I didn't have an account with them but they were more than willing to assist me with my broken A/C system.
Nick the technician was very knowledgeable and worked with me while I was out of state and with my tenants. He articulated very well, explaining all the issues, what the repair process would involve and the cost. There were no surprises. My tenants informed me that Nick was terrific !
Nick got the system up and running. Overall, it was a very positive experience and I would highly recommend GEM to anyone.
Great service. Timely response and got the job done. It’s on the pricey side but that’s expected given their quick response time. Joe was particularly good and have had him out twice on our property. Thanks!
From beginning to end the experience was amazing. It started with my man Walter who calmly with humor explained the process and my guys Ben and his partner who took cared of me and my family. They were professional and very knowledgeable about the process. Their patience when not finding my well was welcome. Awesome job
Thank you
The people are nice, punctual, pleasant.
And best of all great prices. I'm very happy with the service.
I was very impressed with Dory . He was extremely knowledgeable and very helpful.
Awesome service and friendly guys.

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.
