"Our heat pump was making some strange sounds and we called and had an appointment right away! Isaiah was prompt, courteous and professional! He gave us a couple of options to help us with our heat pump issue. We opted to replace the heat pump and furnace and have peace of mind for the next 10 years. During install, Isaiah, Joseph and Michael all did a great job, they all were very professional and would definitely recommend them!!"

"I had a great experience with Nate. He was extremely knowledgeable about A/C systems and was far more well-versed than many other companies in the area. He took the time to explain everything clearly, answer my questions, and make sure I understood the issue and solution. Nate was also very friendly, professional, and informative throughout the entire visit. I truly appreciated his expertise and excellent customer service. I would highly recommend Nate to anyone needing HVAC service."

"The workers were flexible as the design changed as the construction progressed and the work was completed on schedule to our expectations. We would recommend Patsy for your building project ( large or small) now that he is back from a serious leg injury and can better control the quality and sub-contractors. You may call us for additional details regarding our positive recommendation on this contractor, Patsy Cicala."

"Seal Level Construction and Electrical Services ran a 60 amp cable from my 200 amp service to an outdoor plug for my portable generator. They also replaced my attic fan and thermostat. They did an outstanding job from showing up on time, performing all work and cleaning up when they were done. They also set up to get the install inspected and signed off. They performed every task quickly, professionally and were meticulous in their ensuring everything was done properly the first time. The price was very reasonable and I give them my highest recommendation. Feel free to contact me with any questions."

FAQs for furnace / forced air heating system install or replace projects in Seaford, DE

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.
