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 job๐Ÿ‘ 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 GEMโ€™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.

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!

How to Know When You Need a New Furnace Installed

Sometimes, it’s easy to tell you need a new furnace. Other times, though, you may need to look a bit harder to understand if your furnace is at the end of its lifespan.

Your energy bills and your furnace’s efficiency are directly related. As your furnace struggles to efficiently produce heat, it will use more energy to maintain your desired temperature, causing your utility costs to climb month after month. This is often one of the first signs that your heating system in Boston is nearing the end of its lifespan.

Most furnaces last between 15 and 20 years, depending on maintenance and usage. Once your system reaches that age, it begins to lose efficiency and reliability, often requiring frequent repairs. A new furnace installation can improve performance, lower costs, and give you peace of mind for years to come. Whether you’re running a gas furnace or oil furnace in Boston, upgrading to a modern system pays off.

If your furnace constantly turns on and off in short bursts, it’s working harder than it should to maintain your home’s temperature. This frequent cycling not only wastes energy but also puts extra strain on internal components, leading to faster wear and tear. For many Boston homes, short cycling signals it’s time for a new furnace installation.

A furnace that refuses to start is one of the clearest signs that something serious is wrong. While minor issues like a thermostat malfunction or tripped breaker can sometimes be the cause, an aging or failing system may be beyond repair. When you need furnace installation in Boston, GEM is here to help.

We Install All Types of Furnaces in Boston

GEM is here to help your home stay at the right temperature all summer long, no matter what type of system you count on to do so.

Hereโ€™s a look at the types of air conditioners we install:

Gas furnaces are one of the most popular and efficient heating solutions for New England homes. They deliver consistent warmth, quick heat, and lower long-term operating costs compared to other fuel types. GEM installs high-efficiency gas furnaces with advanced features like variable-speed blowers and modulating burners for optimal comfort and energy savings.

For homes without natural gas access, oil furnaces provide powerful, reliable heat even on the coldest days. GEMโ€™s technicians are experienced in both traditional and high-efficiency oil systems and can help you upgrade to a cleaner, more efficient unit that meets todayโ€™s energy standards.

Electric furnaces are a clean, safe, and dependable option for homes that prefer or require all-electric systems. Theyโ€™re simple to maintain and offer steady performance, especially when paired with efficient insulation and modern thermostats. GEMโ€™s experts can guide you through system selection and installation to ensure your home stays cozy without wasted energy.

Looking to make your home more sustainable? GEM offers solar-assisted heating options that harness renewable energy to supplement your furnaceโ€™s power. By integrating solar technology, homeowners can reduce their carbon footprint and utility bills while maintaining reliable comfort through the winter.

GEM is here for all your heating needs in New England. We also work on:

  • Horizontal Furnaces: For smaller spaces, horizontal furnaces are installed on their side, perfect for attics, crawl spaces, or tight basements.
