Benefits of Furnace Replacement in Boston

Replacing your furnace is a big decision to make.

Thankfully, it comes with plenty of benefits that provide you with long-term comfort and convenience. Here’s what you gain with a new system:

As soon as temperatures start to drop and you switch from cooling to heating, you deserve to feel the comfort that comes with even, consistent warmth. A new furnace will make sure you get exactly that, season after season!

When your old furnace begins to fail, breakdowns often happen at the worst possible time. A new system gives you dependable performance you can count on all winter long, reducing the risk of unexpected repairs and stress.

Older furnaces can circulate dust, allergens, and other particles throughout your home. A new, properly installed furnace improves filtration and airflow, helping you and your family breathe cleaner, healthier air every day.

New furnaces are designed with advanced efficiency features that use less energy to produce the same level of warmth. That means lower monthly utility bills and greater comfort without the added cost.

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.

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 Tell When to Replace Your Furnace

Boston’s long winters require a high-quality furnace, and GEM is here to make sure you always have one you can trust.

Most furnaces last around two decades; beyond that, replacement offers better efficiency, reliability, and safety.

If your furnace seems to break down every season, replacing it could be more cost-effective than constant fixes.

As furnaces age, they lose efficiency and use more energy to maintain comfortable temperatures.

Cold spots throughout your home often indicate that your system is struggling to distribute heat properly.
