"I highly recommend this company!!! This is someone who knows their stuff and is willing to go the extra mile to really get the job done! Our heating oil ran out while we were away and we came back to a freezing house and an odd puddle of water coming out of the heater. Thanks to Desmond, we were able to get the heater back up and running properly within a day!! Excellent customer service and very professional! I have used them before and will definitely be using them again!!!"

"It went well. Not sure how many years it's been but Dave continues to solve the many riddles around our boiler (house circa 1930). This time was not so bad but I simply don't call anyone else PERIOD. Waste of time when you can work with a savant. Just as an FYI - he's pretty much done my entire basement from PEX to a water filtration system."

"Speer Air just completed a complete overhaul of my existing HVAC including an upgrade of part of our system. The entire experience from initial sales visit to completion was great. Throughout the installation, the team was friendly, always available to answer a question, clean and respectful of my 3 young children (making sure nothing was left behind or any debris that could hurt them). System is operational and very satisfied. Highly recommend them."

FAQs for furnace / forced air heating system install or replace projects in Randolph, 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.
