"J & J Air, installed our new Trane system a couple of years ago and did a wonderful job. Installation went very well, on a terribly hot day, the team did a great job, with no mess left behind. We have had a couple of Mechanical issues 1 with a broken part, and 1 with a failed switch. Both times the J & J teams showed up on time and resolved the issues as needed. Jeremy and his team are to be commended for their efforts and their Customer Service."

"I had them service the heating portion primarily . It seemed to be working harder but nit putting out as much heat as it should . Aaron who has worked on our system did a great job . Since it was a service he checked the whole system , found a weak capacitor and a dead fuse which caused half of the heating elements to not function . Aaron is always polite , very professional and dies nit wast time . He had the capacitor on the truck and did the new Instalation and had to order the fuse for the heating elements . It was a job well done I would add that I am not comparing the cost of the item with other AC companies . The item needed to be replaced , I trust comfort air unless they give me reason not to trust them"

"If I could give this company a hundred stars I would. They replaced our heat pump and complete HVAC system for a very reasonable price. The project was massive and took five days to complete but Robert, the owner, and his helpers are so pleasant and unobtrusive that it was not an ordeal to have them here for that long. If you are considering heating related projects and services, you would be foolish not to consider this fine company."

"Chad came out the same day and did a very thorough analysis of the inside and exterior heat/AC unit. He changed the filters and all his recommendations to both me and with my husband on the phone as well about his concerns. We value his expertise and we are very impressed with this company. Glad we made the decision to switch to ARS."

"We installed a 12,000 BTU split AC system to cool an enclosed balcony in our 70 year old church. The installation was much more difficult than at first appeared. A special drill was rented to bore a 3 inch hole through a full foot of extremely hard brick. This took a couple of extra hours. Then electric connections had to made running about 100 feet through a crawl space crowded with central AC ducts installed by another company. This was extremely difficult and time consuming. When it was all done the entire job took several hours more than projected. Advanced Air stuck by their original estimate even though it was obvious that they lost their profit on this job due to the unanticipated difficulties. The management and workers were careful and respectful throughout the process. The final result was attractive, functional and all the difficulties were out of sight. Great job!!!"

"The salesman (Tom) was involved and available throughout the whole process from providing multiple alternative quotes and advice to a follow-up visit after installation. The installation team showed up on time and worked straight through till the system was installed. They walked me through setting up the system, app and thermostat. The cleanup was well done and complete. O'Brien did a great job and I wouldn't hesitate to recommend them. A very professional company."

"Called him at night said he would be here at 11 am..On time, saw what the problem was explained it to me, and in a mater of one hour he had put gas back into my heat pump and charged me less than half what the last guy charged for the same amount of gas and time.You won't be overcharged and you can trust and depend on Advance Air Systems.

FAQs for furnace / forced air heating system install or replace projects in Ocean Isle Beach, NC

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.
