"Called Sam on Friday for quote for water heater replacement. Said he could do Monday afternoon or Tuesday morning. Received call Monday morning to see if he could come on over to do replacement, what a pleasant surprise! Sam arrived shortly after with water heater we discussed & all supplies needed , no running around to pickup stuff. Job completed in timely manner. Old unit hauled off and job site all cleaned. That’s a big deal to me. Will not hesitate to recommend Liberty to friends & relatives ! Thanks Sam , Dave & Roxanne"

"Glen was great. He explained everything he was doing as I watched so I could learn how to drain the water heater myself. He checked the pressure in all the faucets & cleaned up afterwards. I’d definitely hire Hosack again...and request Glen."

"I cannot say enough wonderful things about this amazing company! My daughter and I had been without a furnace for over 6 years. We used space heaters in the bedrooms, bathroom and kitchen, but the rest of the house stayed cold. Along with that, I had a constant fear of an electrical fire resulting from the units, because last year a young mother and her baby died in a house fire down the street from us, most likely caused from a space heater. When Schraer came to our home that offered to install gas furnace free off charge that was just sitting in their shop! We are truly Blessed and Grateful for their kindness and generosity! There are good people out there in the world, and the owners and employees of Schraer Heating and Cooling are some of best!"

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.
