"First, my project was to install, from scratch, a new HVAC system, including ducting, with tha furnace in basement (initially, it was upstears in a closed). Last year and early this year, I got 3 contractors on site, by direct call, and none of them answered my spefic questions but taking pictures and promising that will send an estimate. I never got it. I was getting anxious. So I got the idea go to Angi. First visit I got in the same day I put my request on Angie's site, called his boss advice me to just change the furnace. I could not, because the previous system was heating OK only one half of the house. Finally, next day I got AJB visit an made me happy. He understood perfectly what I wanted and my concerns and explained to better and quite ingenious solutions on my suggestions. I understood him perfectly because I have strong knowledge of aero-dinamicsor or fluid mechanics so I signed the contract right then. Now, I have a sweet warm house in every corner of it."

"Mr. Bost did an excellent job for me for a reasonable price. I know he obtained the best deal for me on the furnace and the air conditioning unit. He answered all my questions. He was on the job when he said he would be; he was professional and courteous. The installation went smoothly, and I have had no problem with the furnace or air conditioner since they were installed in 2008."

"Bryan and his team were punctual, clear about the order of work conducted, and all around professional. The tasks were completed in a timely fashion (over 2 1/2 days), with consideration of the fact I am working from home. They also agreed to wear face masks inside at my request, despite the heat and discomfort. More importantly, Bryan was very clear up front that his quote was just that: an estimate of the work to be done, with room for adjustment at the other end. I not only recommend BCG but I would hire them again should the need arise."

FAQs for furnace / forced air heating system install or replace projects in Maryland Line, 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.
