"Our natural gas furnace stopped working the day after Christmas. Most heating services were closed for the holidays but Ocean State was one of the few who would take the Friday afternoon call. Repair were done quickly and heat was back before it was cocktail hour. Ocean State is now our primary HVAC service provider."

"Chris was quick to respond to our request for a quote for a new furnace. We had requested quotes from several other companies and most didn't respond, call back or show up when they said they would. He was very friendly & knowledgeable. He sent us a quote the same day. We are very happy with our choice to have CMA Heating & Air install our new furnace. We would highly recommend him!"

"MTS was quick to respond to our call and evaluate our system. While they found nothing that required repair right now, they did help us understand the timeline for potentially replacing our system. My only disappointment is that I haven't received the replacement quote they said they would provide."

"I used Angi's to get bids for installing a 4-head mini-split system while undergoing a kitchen remodel. Thankfully, Angi's was a reliable referral source, and I got 6 companies bidding. Cassana wasn't the cheapest, but Phillip, the owner struck me as earnest and reliable. He made several recommendations for my house's set up, and his crew was diligent and professional. Within 3-1/2 days, I was up and running. He was great to deal with, professional, and let me know of a previously unknown incentive rebate that save me some $3,000 on the job! No worries, and a great company to dela with--I liked them much better than some of the 'big firms' with high overhead and pressured sales practices."

"Hiring Williams & Assoc. has turned out to be one of the best decisions Iâ ve ever made! From the very start, this experience was excellent! Bruce and his team were professional, kind, and helpful when describing the system we purchased and answering the hundred questions we had along the way. Their attention to detail and all of the little extras one wouldnâ t even expect to receive were provided as if it were second nature to them. And the team worked tirelessly, without stopping until the job was finished. We were happy to have them in our home. These are genuinely good people. Our old boiler was past the point of being dangerous. Smoke filled the basement every time it came on. Anyone could see that we were in an emergency position and had no choice but to replace the old system. Some companies Iâ ve dealt with in the past would have taken advantage of our situation. But not Williams! The price for our new high efficiency heating system was very â veryâ reasonable. Due to our situation, the work was started and completed almost immediately and the service was excellent! My wife and I highly recommend Williams & Associates."

FAQs for furnace / forced air heating system install or replace projects in Portsmouth, RI

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.
