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.

We had a leak in the feed tube going into our toilet. It leaked down through the ceiling into our kitchen. I called GEM and they sent technicians right out to fix the problem. The technicians arrived, assessed the problem and gave us a very reasonable quote. The technician also noticed veteran plates on my car and applied a 10% discount! They fixed the problem, noticed that the feed tubes to my sink didn't look good and corrected them as well. Both technicians were very personable and kind. They helped lower our anxiety as well. Great experience! Highly recommend GEM plumbing!

Two great gentlemen (Brandon and Maxwell) came to my house to fix a leaking faucet. They explain all the questions from me and wife. They even give nice advice about reglazing the sink. Due to the distance between the cabinet and the sink, they tried very hard to find the best possible solution for us and install a new faucet. It is a wonderful job!! Highly recommended!!
The GEM service technicians showed up promptly. They were quick and efficient with their service. They had good recommendations and were very cordial. I would call on them again.

I have already posted a 5 star review and want to post another. Four years after becoming a GEM customer, I remain totally satisfied with their service. I could name a lot of names: Nathan Campbell, Tony Rossi, Michael Hassel, Steven Gray and his partner Chase, and others who have all been incredibly responsive and totally dedicated to solving the problem at hand. I think for an organization as large as GEM they have managed to recruit and train a great group of professionals. All that matters to me is quick access to such a good group caring pros.

The service and attention to detail is excellent. They identified the problems with 2 toilets and 2 shower faucets and resolved every issue with the least amount of disruption. They even went the extra mile to identify the cause of a ceiling stain to make sure it wasn't from water. I recommend them highly for quality of work, knowledge and efficiency.

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.
