"Chris was very polite. He was punctual and gave me plenty of notice of when he would be here. He installed two huge ductless heat a/c units. He was very knowledgeable and gave me options for different units. I saw him measure at least twice and used a level to ensure everything was level. I loved his attention to detail. He seems extremely trustworthy. I felt very comfortable with him. I will recommend him to anyone I know who needs this type of work."

"Myron contacted us within 15 minutes of us submitting our information on Home Advisor and got on the job of figuring out what was going on with our 17 year old 2.5 ton HVAC unit. As a Professional Engineer with over 35 years experience in HVAC I found Myron to be very knowledgeable and honest about what my options were for getting my AC system up and running. Unfortunately we needed to replace our furnace, evaporator and condensing unit and Myron recommended the Run Tru by Trane at a very competitive price and we had his folks install the system. They showed up on time to install the system and did their work in a very professional manner. They left the job site cleaner than it was before they came. Overall we are very happy with the results and will call Myron when our other unit needs to be replaced."
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.
