GEM: Your Local Johnston Furnace Installation Company

Johnston sits at higher elevation than Providence, and that means colder overnight lows and different heating demands than properties closer to sea level.

The Route 6 corridor through town sees plenty of traffic but not much foot traffic – this is residential Rhode Island where homes are spread out and heating systems work hard all winter. GEM’s technicians have worked in Providence County for decades.

We know which furnaces hold up through 15 Rhode Island winters and which ones don’t. We account for your property’s elevation, insulation, and layout when we size equipment – not just square footage from a tax card.

Excellent service in every respect: starting with the salesperson, Peter Dallas; Sean, the installation coordinator; and, of course, the installers Joe & Cristar!!
Pete was extremely professional, friendly, understanding and very flexible when negotiating the final price.
After 28 years of using a Lennox central heating and air conditioning system, we decided was time to get new systems and we went with Carrier this time, a highly respected brand too backed by GEM Plumbing as a certified provider. Both the sales process and the speed of the installation were incredibly efficient. We spoke with Peter on a Tuesday morning , and by 3:00 p.m. on Friday of same week the installation was complete. We were lucky enough to have Joe Medeiros and Cristar Fig from GEM as our technicians!
Let me tell you, this duo is exceptional! They are very young but possess extensive knowledge and a fantastic attitude. I was truly impressed by their technical work and their courtesy. These two technicians are a great asset to GEM and WE would love them to be recognized! We are very happy at home; the air conditioning system works wonderfully! And We can’t wait to use this coming winter our new furnace too!
Thanks to Peter, Sean, Joe, and Cristar for their amazing job!!

How to Know When You Need a New Furnace Installed

Your furnace won’t last forever, and recognizing when replacement makes sense can prevent sudden breakdowns and higher energy costs.

Here are the key factors our team considers when helping decide if you need a new heating system:

If your furnace needs frequent service visits or keeps breaking down throughout the heating season, you’re likely spending more on repairs than the system is worth. Instead of continuing to patch an aging unit, invest in a new furnace for reliable comfort and long-term savings.

When some rooms stay warm while others remain cold, your furnace may no longer be distributing heat properly. This often happens when the blower motor weakens or internal components wear out, signaling that replacement is the smarter choice. When you need furnace installation in Johnston, GEM is here to help.

If your energy bills continue climbing even though your heating habits haven’t changed, your furnace is probably losing efficiency. Older systems must work harder to generate the same amount of heat, wasting energy and increasing costs. A modern, high-efficiency furnace can dramatically reduce those monthly expenses.

Most heating systems last around 15 to 20 years with regular maintenance. If yours is approaching that age, start exploring replacement options before it fails during a frigid Johnston winter. If your heating system in Johnston is nearing the end of its expected lifespan, upgrading now prevents emergency situations later.

We Install All Types of Furnaces in Johnston

Every home has different heating requirements, and at GEM, we install a complete range of furnace types to match your home’s layout, energy source, and efficiency goals.

Our licensed HVAC technicians will help you choose the best system for your space, budget, and long-term comfort. Here’s a look at the types of furnaces we install in Johnston:

Gas furnaces are among the most popular and efficient heating options throughout Rhode Island. They run on natural gas to deliver steady, powerful heat, making them a smart choice for homes with gas service. GEM installs gas furnaces in Johnston that provide reliable performance and help lower your monthly energy bills, even during the coldest winter nights.

For homes without access to natural gas lines, oil furnaces offer a proven, dependable heating solution. These systems generate strong, consistent warmth and handle New England winters with ease. GEM installs high-efficiency oil furnaces in Johnston designed to maximize heat output while minimizing fuel consumption, giving you reliable comfort throughout the heating season.

Electric furnaces deliver clean, quiet heat without requiring gas connections or oil storage tanks. They’re an excellent option for smaller homes or properties where electricity is the primary energy source. GEM installs and services electric furnaces that provide even, comfortable warmth with minimal maintenance requirements.

If reducing your environmental footprint while cutting heating costs appeals to you, solar-assisted furnaces combine renewable energy with traditional heating methods. These systems use solar panels to capture energy from the sun, supplementing your furnace’s power needs. GEM can help design and install solar-supported heating solutions that deliver sustainable comfort year-round.

Don’t see your preferred furnace type listed here? GEM also installs horizontal, upflow, and downflow furnaces to suit your Johnston home’s specific configuration and installation needs.

  • Horizontal Furnaces: For smaller spaces, horizontal furnaces are installed on their side, perfect for attics, crawl spaces, or tight basements.
  • Downflow Furnaces: Suitable for attics or other high placements, downflow models pull in air from above, distributing it downwards.
  • Horizontal Furnaces: For smaller spaces, horizontal furnaces are installed on their side, perfect for attics, crawl spaces, or tight basements.

Furnace Installation FAQs

What are the signs I need a new furnace?

Common signs include frequent breakdowns, rising energy bills, uneven heating throughout your home, and a system that’s 15 to 20 years old. If you’re experiencing any of these issues, it’s worth having GEM assess whether repair or replacement makes more sense.

How much can I save with a high-efficiency furnace?

High-efficiency furnaces can reduce your heating costs by 20% to 40% compared to older models. The exact savings depend on your home’s size, insulation, and how much you currently spend on heating. GEM can help you calculate potential savings based on your specific situation.

What size furnace do I need for my Johnston home?

Furnace size depends on your home’s square footage, insulation levels, window quality, and ceiling height. Our technicians perform detailed calculations to determine the right capacity, ensuring your system heats efficiently without cycling too frequently or wasting energy.

Can GEM install my new furnace quickly if my old one breaks down?

Yes. GEM offers same-day service throughout Johnston and can often complete emergency furnace installations within 24 hours to get your heat restored as quickly as possible.

Do I need to replace my thermostat when I get a new furnace?

Not always, but upgrading to a programmable or smart thermostat alongside your new furnace can improve comfort and efficiency. GEM can assess your current thermostat and recommend whether an upgrade makes sense for your situation.
