"I was able to get a same-day appointment, and Abraham showed up right on time. He took a look at the system and confirmed that the furnace was running as expected, and he didn’t find evidence of a cracked heat exchanger. I was hoping for a definitive answer as to why the air wasn’t flowing out of several of my vents, but he was only able to confirm that it wasn’t due to the furnace itself. I may have clogged or separated ductwork behind the walls, but he wasn’t able to diagnose/confirm. At least I know the furnace itself isn’t the source."

"Affordable Heating and Cooling did an amazing job installing my new split system on New Years Eve!! Dave the owner, was in constant communication with me from start to finish and was meticulous with all aspects of the project. They were very neat and cleaned everything back to the way it looked before the project began. A pleasure to work with and he even gave me a bunch of free advise about other aspects of my nearly 100 year old heating system. They will be my first call if I have any other heating or cooling needs!"

"These guys are great. They came to assess the situation (problems with our oil furnace) and thoroughly reviewed options. We went with them for a furnace replacement, as well as a heat pump to replace our standard a/c units. They came in much cheaper than the two other companies we consulted (one of which we had used for almost 50 years (since the house was new). We're thoroughly happy with our new HVAC setup, and even the fancy Nest thermostat. Highly recommended!"

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"Joe checked out my AC system in the spring and advised a system recharge when temps were higher. Didn't bill me until work was all done a few months later. Stand up guy. Good work."

"Jorge and his team responded to my request for central A/C repair on the very day I called him... and just as the heat wave struck our area! Jorge and his team were highly professional and fixed the problem immediately. He was available for follow-up and extremely responsive to any questions or concerns that we had. The unit is fixed and functioning perfectly now. I recommend Jorge Montes without hesitation whatsoever. He is prompt, reliable, capable and extremely professional."

"We finished our basement last year. At that time we upgraded our existing furnace so that we can heat both main floor and basement. Another HVAC contractor (not Bell Heating) performed this task and added two zone dampers for the two floors. After this work was complete, the main floor was always overheated. Since the original heating contractor refused to fix this problem, I contacted Bell Heating. George from Bell Heating explained that the zone damper for the main floor is stuck at open position blowing hot air all the time. The original zone damper was in a very difficult to reach position above a corridor and there were gas and drainage pipes surrounding it. George and his supervisor worked very hard to cut ductwork to extract the old zone damper and patched the hole. They ordered a new one to replace it. When the new one arrived, they placed the new zone damper in a position which can be easily accessed. This work involved repeated visits from Bell because the damper was not a size that is readily available in market. Now everything is working fine and main floor heating is again controlled by the thermostat as it should be. I am very pleased with Bell heating for fixing this problem."

FAQs for furnace / forced air heating system install or replace projects in Thornwood, NY

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.
