"BC HVAC Services was fantastic to work with. Had heating issue and was spot on with diagnosing the issues. While keeping the old furnace running which was challenging he swiftly ordered a new unit to minimize the time potentially with no heat during the winter. Grateful to Benny and his team for managing this so promptly and professionally. Due to the age of both heating and central air, both units were replaced at a great price. I would highly recommend BC HVAC Services for all your heating and cooling needs."

"Kevin & Dave, hope I have names correct, worked hard and very professionally to replace my boiler on some of the coldest days. Work started at 0800 and went well past 2 a.m. without taking any breaks. I came to think of the mechanics as my buddies as they were so easy to talk to and willing to answer all questions. I love my new boiler and was also able to turn the heat up in the house as my new boiler is 95% efficient. Their office was very helpful, informing me of every step of the way of boiler installation. All plumbing associated with the old boiler had to be removed and replaced to fit my new tank less boiler. I enjoyed having them here and have invited them to come swimming this summer!!"

"Excellent to work with, hired them for a fireplace and furnace certification prior to selling my condo. They were thorough, punctual, pleasant, and extremely helpful with replacing a small part after something stopped working the second time they tested the furnace."

FAQs for furnace / forced air heating system install or replace projects in Freehold, NJ

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.
