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.

The service was good.Aiden was very good. It’s just they said they were on there way 2hrs and30 min they finally arrived. Waited all afternoon
The 2 service men were on time, assessed the problem, diagnosed the issue, came up with a plan and offered several solutions for fixing our mini split. They took pictures, tried clearing out mice debris , attempted to get the outside machine to work ( apex 2 hours) Alas a no go, so we decided to scrap it and go with baseboard heater for the room over the garage. Up front information and pricing , no nonsense. Affable techs and so far great service.

I was thoroughly impressed with the superb HVAC maintenance service I received from David Santiago and trainee, Kevin today! Before David and Kevin arrived I was very disappointed with having had my original service date rescheduled to what I thought were spurious reasons? In fact David and Kevin arrived after the designated rescheduled date and time today. GEM's communication was excellent throughout and their people seemed genuine and concerned. When David and Kevin arrived it turned the whole situation around. They could not have been more professional and knowledgable! I am now firmly committed to GEM and their Home Comfort maintenance program.

We just had our heating system replaced. We went from forced hot water system to a central heating and air conditioning system done by GEM plumbing and heating company We had Omar and Michael work in our home for 5 days they installed all the ductwork, the furnace and the condenser. These guys were very professional, kind, clean and informative throughout the whole install every day they explaind what they did and what is the expectation for the next day. Today was the last day they walked me through the whole system, how to change the filter how to operate the new thermostat and what to look for when things are not working properly. I say thank you to the whole team from planing to done, all went great to expectations

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.
