"Excellent! We did a whole house remodel in 2013 and Holtzople installed the geothermal system. Our utility costs went way down compared to our previous oil furnace and electric central air conditioning system. We then signed up for their semi-annual maintenance agreement so they send a technician out every year for a tune up and cleaning before the heating season and again before the cooling season. Big shout out to Kevin, the technician who usually performs the maintenance, for his professionalism and friendliness. For 8 years now we've been enjoying care free climate control in our home at a lower price than I ever would have imagined. I highly recommend Holtzople for their products and service and Geothermal for efficiency."

Customers say: Quality work

"I have used Freedom Comfort Services in the past installing mini-split system and now (at another house) replacing an oil furnace with gas. They are priced better than the other companies that I got quotes from AND they took the time to measure the spaces in the house to know what I would need. They communicated great and were always punctual. When our old furnace went out they worked quickly to order a new one and when it came in, made sure it was installed that day. You can tell that they care! That's important to me."

"Jay Bee came out very late on a Saturday night to look at my mom's furnace. Unfortunately he needed to obtain the part from a supplier so that had to wait until Monday. He brought several electric heaters to help until the repair could be made."

FAQs for furnace / forced air heating system install or replace projects in Dover, PA

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.
