"Shawn performed the annual heating inspection for our furnace/oil tank. As always he was very quick, and took extra time to walk me through the piping of our different heating zone. Highly recommend Genove Oil, they are providing stellar service and with employees like Shawn you are in very good hands."

"Fantastic. Jeff is a pro. Installation went as described in both locations. He came back Immediately when I had a water gauge issue for my water meter ( installed 7 years ago) and replaced it on the spot. Jeff is professional, punctual, cleans up, old furnace removal and does great work. I’m very happy with my 2 new efficient heaters and hot water heaters! My heating costs are down substantially! I’m glad we chose Jeff."

"I found Chambers Heating and AC thru Angie's list and Stephen reached out to me the same day. We set up an appointment and Kevin came out the very next day. Kevin showed up on time and fixed our issues right away. He was kind and professional. He also gave me some tips to keep my system in tip-top shape. The price was very fair and they have gained my business. I will hire them again for future repairs and maintenance."

"Probably the best contractor I ever worked with. They delivered exactly what they promised, on time and without any hassle. They replaced my 24-year old oil furnace with a highly efficient gas boiler and water heater. Jeff and team organized everything, including permits, the timing of the oil tank and boiler removal, the delivery of the different heating system parts and plumbing supplies and the gas meter installation. They worked very efficiently and left the place cleaner than it was before. I can't stop admiring the wall with the new piece of art of engineering I have now in my expanded basement! I would highly recommend J. Griffin Heating and Plumbing to anyone looking for upgrading their current heating system."

"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"UIC was quick to respond and come up with the quote. Quote was very competitive against others. They were not so eager to do service on my old water heater though (I asked them to replace anode rods). I decided to go with them since their availability was good (2wks) and ratings on AngiesList were excellent while price was competitive. The job went well, though not without hiccups. I was expecting new boiler to be placed on the wall next to the foundation; though they built a new wall in the middle of the mechanical room, which costed me space; they said it will be 3K more to put in on the wall AFTER they arrived on the job with all the equipment and team. They refused to drain old water from my radiant heat system, saying I need a plumber to come for $290 per hour for 4 hours to drain the system and look for preexisting leaks. Had to hire some other plumber who took care of the problem for $215 in a mere hour. After the project was complete, system started to experience leaks. It was due to new drain connector that they decided to use for this project, and I was apparently first customer for it. After 3 unsuccessful attempts to fix the leak, they had to replace the connector, which addressed the issue. In addition, the system was eligible for rebate; however the rebate amount promised ended up being $450 less than actually paid; they quoted natural gas rebate though my system was on propane, which I told them upfront."

"We've used Atlantic Heating and Air Conditioning for over 10 years for regular air conditioning maintenance/service and repairs. They also do service/repairs for our heating system. Recently, they provided valuable advice that allowed us to fix a thermostat malfunction on our own, saving us cost of a visit. We've always been satisfied with this company - visits were easy to schedule, staff were knowledgeable, work performed was well done."

"Even though our furnace died (it was old) still have to commend the professional, knowledgeable and kind staff at Green Energy who not only came over immediately to render assistance but also brought us space heaters while we wait for them to install our new system. Irvin lightened the mood and answered all our questions while helping us understand the issue and pick the best next solution. Terry was awesome since day 1 and both have been great with our kid ð ¶. Thanks Irvin & Terry!! -Lisa"

FAQs for furnace / forced air heating system install or replace projects in West Medford, MA

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.

Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.

With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.

The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.

Consulting with an HVAC professional can help you determine the exact size that's right for your home.

An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.

An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
