"I have used this family own business for three different jobs. They put in a brand new system in my place of business, They replaced my heat pump at my primary residence and they replaced my heat pump and ductwork at my cabin. All of the jobs were done very professionally, and the price was reasonable. I will continue to use them for all of my heating and AC needs. Matt and his sons are great."

"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."

"Oil delivery has been excellent. Their records and calculations have allowed them to make timely deliveries of home heating oil. I no longer have to watch the level in my oil tank and call as I had to do with my previous supplier. Delivery people are friendly and efficient. We also pay using a budget plan and this has worked well also. Each year we have one of their technicians maintain our furnace. The technicians are well trained and have all the parts needed to maintain our furnace. Very well pleased with their service."

"There was only one hang up. When I contacted them through e-mail I indicated that I wanted to talk about installing an antique wood burning stove in addition to the chimney inspection and cleaning. The appointment was made for the afternoon on a certain day. But, the guys called that morning and left a message on my voicemail saying they could come early. I did not get the voicemail and they showed up early anyway. I was not home but my mother was there. Unfortunately, these guys did not get the word from the scheduler in the office that I wanted to talk about the installation of the wood burning stove in addition to having the chimney cleaned. So they came did they work and left. I called the workers back (since I had their phone number from the voicemail) and communicated my annoyance at the schedule change. The guy was very apologetic and offered to come back though he was no longer available at the scheduled time which I had blocked off on my calendar.
However, we ended up talking about the project over the phone and he was able to give me all the information I needed about the potential installation over the phone. He was very knowledgable and helpful. So, I'd like to give them a "B" for punctuality though that doesn't seem to really fit the situation. So they get all As despite this little hitch.

FAQs for furnace / forced air heating system install or replace projects in Friendsville, MD

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.
