Customers say: Quality work
"I liked that John explained everything to me and gave me choices in the level of service the job required. I had a small issue with the radio controlled fan installed, but they came back the very next day and adjusted the system in 5 minutes. They always left the site clean and took boxes and old equipment with them. Excellent Service!"

"Promptly returned email regarding service request, on Saturday. Responded same day to repair 2Ton Geo unit (Waterfurnace). Extremely knowable on geo-thermal systems, the repairs were made in timely manner at a fair price, my only regret on this geo unit is I should have had Continental install the system in the first place, it’s seems very likely I would not be haveing the maintenance issues."

"Excellent mini split installation and service from start to finish. The team was professional, respectful, and very knowledgeable. The energy report was extremely helpful and led to insulation improvements that provided real energy-efficient benefits and cost saving credits. Everything was clearly explained, and the work was done neatly and on time. I highly recommend them."

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.
