"This company does not answer my phone calls. We never knew when they planned to arrive to work on our installations. We ordered three air conditioning units and three heating units. The last unit was a heat pump instead of a regular air conditioner but I allowed them to install the unit since we were told the fan would run when the temperature was below 32 degrees.. Lennox shipped the wrong unit. We were not familiar with a heat pump. The unit fan runs constantly and the installer will not return my phone call."

"We added a spacious garage to our home and wanted to install a mini split system while relocating our existing air conditioning unit. Since my husband and I were new to mini splits, we had plenty of questions. Taylor the owner of Shaffer’s heat and air was incredibly helpful in guiding us to the best system for our house and garage. They sent Stephen out to handle the installation, and Stephen arrived right on schedule, proving to be both friendly and efficient. The project took two days, and on the second day, Taylor joined Stephen to wrap things up. They worked seamlessly together, completing the job on time with everything looking tidy and well-organized. It's been over a year since the installation, and everything is still functioning perfectly! We will definitely be using Shaffer’s heating and air for our next project! Thank you guys!"

"After some heartfelt discussion, our miscommunications were rectified and we now have a solar system that is producing excess electricity, and the EnPhase monitoring system is top-notch! The staff at Solergy is always pleasant, respectful, and always works diligently within their roles. Roderick is very smart and has fulfilled his commitments. Based upon referrals from friends and our satisfaction with our solar installation we can recommend Solergy for a home solar power system."

"I was having a problem with MS Office not responding and other files being very, very slow to open. Jim started looking for the cause right away. He did numerous checks for viruses, malware, and various other things that can go wrong. He vigorously pursued a resolution pretty steadily for two days before determining it was a malfunctioning external backup system that was causing the problem. With that finding, he promptly got my computer running smoothly and very fast again. He made two trips to my house; on the first one, he had to cross a sheet of ice in my driveway. Jim is a very capable and experienced computer analyst that will get after your problem because he fully understands the importance of, and the need to have a working computer in the house.

FAQs for furnace / forced air heating system install or replace projects in Fort Smith, AR

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.
