A new HVAC system delivers more consistent temperatures from room to room and better humidity control throughout your home. Many systems also offer advanced filtration options that help reduce allergens, dust, and airborne pollutants.

Conducted troubleshooting of Rannai combi boiler. Tech was knowledgeable and thorough. Explained everything.
Tech was prompt, informative and competent—-well done. When making appointment I requested ball park figure for general servicing. Was told a tech would contact me with that information—- that didn’t happen and I was blind-sided relative to service costs.
Walter and Anthony arrived to install my new washlet toilet (bidet) and it was Completed in no time. A great new addition to my guest bathroom with the excellent service that GEM Always provides!
serviced our split system in a competent and efficient manner
Very professional and knowledgeable
Jacob and his partner were great, professional, friendly took the time to show me how to shut the system off if I needed to in an emergency and tagged it for me.
Brain and partner were very Informative and explained what he was going to do , both were friendly
Upon turning on the water in a seasonal property, a dramatic, high-impact plumbing emergency was there to greet me!  I made a few calls – Gem Plumbing was quick to respond, and quite compassionate with their handling my excited concern.   Very shortly after as announced (time of arrival, name of tech. and photo) – Aaron P arrived in his van like one of the super heroes from the Saturday morning cartoons I used to watch.  Yet, I digress.  Aaron was clean, well dressed (for the job) and quite congenial.  Of course, the news that Aaron delivered was unfortunate (for me) and not what I wanted to hear – however – I could tell with Aaron's presence that everything would be ok in the end.  Aaron clearly has great mastery of his skilled profession.  Beyond that- Aaron was courteous, engaging, respectful, and unfazed by the mess he walked into.  So – as I sit here composing this accolade, Aaron is working on the last part of this multifaceted cluster of a plumbing problem.  I must say – the work is pricy – but – for one:  I couldn't do it, and for two:  I KNOW – I am FULLY confident that all of the issues will be resolved by the time Aaron gets back in his van and drives away.

I am NOT amused with my Higher Power's sense of humor today, but I am glad help was just a phone call away.  Thank Aaron – super-hero!

PS – unfortunately ***** I can't give a higher rating than 5 stars.
Just had a plumber out to check my pipes to ensure there were no issues and it was covered under my plan so it Didn’t cost me any out-of-pocket money. Great job as always.
The visit was for an HVAC check per our maintenance contract. Anthony did a great job. He was on time, on point, kind and courteous. He answered my questions and went out of his way to get the job done. Thank you Gem for sending Anthony our way. Thank you Anthony. You are an asset to Gem Plumbing.

Tyler was most helpful and knew what our service required . I also purchased a service contract.
Jordan did a great job. My wife called Gem Plumbing & Heating this morning and Jordan was at our home by the end of the day. The office kept us up to date on Jordan’s schedule so we were assured he was on his way.
Great tech. Very professional, efficient and expert in his advice. Just a great representative for Gem. Couldn’t be happier with the service.
When a tree came down on our power lines over Memorial Day, Steve responded and immediately put us at ease during a very difficult time. Our family is currently navigating a significant loss, and dealing with this unexpected situation felt overwhelming. Steve was compassionate, professional, and incredibly respectful throughout the entire process. He took the time to explain what needed to be done, answered our questions, and worked quickly to restore everything safely. His patience, understanding, and genuine care meant more to us than he probably realizes. We are truly thankful for his help and exceptional service. Thank you, Steve, for going above and beyond when we needed it most.
Steve came out on Memorial Day after a tree fell onto our electric lines, and we truly couldn’t have asked for a better person for the job. My family recently suffered an incredible loss and we honestly were not prepared to handle something like this on top of everything else. Steve was not only professional and knowledgeable, but incredibly understanding and patient with us during such a stressful time. He explained everything clearly, worked efficiently, and made us feel like we were in good hands the entire time. People like Steve are rare, and we’re beyond grateful for his kindness and help when we needed it most. Thank you Steve!
Christopher did an excellent job repairing our central air conditioning system. We were his last stop on what I’m sure was a long and busy day in May. He had to get into our attic through a small ceiling hatch in the dark and there was no complaint or negativity. He got the system up and running quickly and had a great attitude.
Christopher Cennamo checked my AC System. He explained things I was unaware of! I was extremely happy with him!!! Thank you Christopher!!!
He was prompt, honest, very thorough and extremely pleasant. I will hire him again in a heartbeat. I just did not get the invoice in my email as promised and the HVAC is not working again after a week -87 degrees in the house again. May need to replace and not repair something.
Technician explains work well and seems very competent. The inability to know, even within hours, his schedule is a substantial problem.
Great job by Nicholas!
Experienced and solution oriented, great work on a complicated set of systems!
Great service !

Is It Time to Replace Your HVAC System? Watch for These Common Signs

When your HVAC system starts to struggle, your comfort and energy bills often pay the price. Knowing the warning signs can help you plan ahead and avoid a sudden breakdown at the worst possible time.

Most HVAC systems are designed to last around 10–15 years with proper maintenance. If yours is reaching that range, a replacement may be more cost-effective than continuing to invest in repairs.

Occasional repairs are normal, but repeated service calls can quickly become expensive and frustrating. If you’re fixing your cooling or heating system every season, it may be time to consider upgrading to a more reliable solution.

An aging or inefficient system has to work harder to heat and cool your home, which can drive up your utility costs. A new high-efficiency system installed by GEM can help lower monthly energy expenses.

Hot and cold spots, weak airflow, or a system that constantly runs are signs it’s no longer performing at its best. Replacing your equipment can restore consistent comfort and give you better control over your indoor environment.


Start Your HVAC Replacement with a Team You Can Trust

When your HVAC system can’t keep up, you deserve a solution that’s efficient, dependable, and built to last.

Schedule your HVAC replacement consultation with GEM today to take the first step toward improved comfort and lower energy costs. Our team makes your HVAC replacement simple and stress-free from start to finish.
