"Ali was very easy to contact and talk to. He clearly explained the different steps, potential issues and associated cost. Talked me away from switching the whole system to the new refrigerant. Great overall! Made it very easy (we usually do not like interacting with contractors)."

"Professional,prompt and attentive. The previous company installed low quality parts and I continued to have problems. Surefire installed what appears to be good quality parts and my heating system is still working. I would definitely use them again and would also recommend to my family and friends. They are also reliable and prompt. They gave me a window period between 8-10 and they arrived at my house at 10:00. Many companies will have you waiting all day but not Surefire. I want to thank them for a job well-done."

"This company went above and beyond to get the heat back on at our horse farm. Bill kept us informed and was there when he said he would be. They are extremely professional. I liked his company so much, that we hired him to do a complete a/c and heat pump in our recently purchased Sag Harbor house."

"He was excellent. He added 3 dedicated lines from my kitchen appliances to the panel bringing everything up to code. He also suggested a line for my bedroom vanity where I gave heated hair tools. He put in extra outlets for me. His prices can’t be beat and he recommended things he felt I could benefit from. He was clean and fast. He had two other men with him (if think one of them was his son) and everyone was friendly and professional. All done within hours. So glad I now have a reliable electrician!"

"Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

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