"Drew has an excellent eye for detail, and his inspection and assessment of our heat pump system was exceptional. He corrected a problem with the thermostat, cleaned and inspected the system, and showed me what the condition of the system looked like. Honest, fair, and knowledgeable! Definitely a professional technician - not a "parts replacer.""

"Holston Homes knows their stuff! Colin helped me decide the best type of heat and air system, priced options, and got the job done quickly. He also installed a whole house humidifier, which is a game changer in winter when the heat is drying everything and causing static. Not with the humidifier!"

"Jack showed up when he said he would to diagnose my heat pump issue. It turned out my heat pump was 17 years old and the indoor unit was 30 years old and both needed to be replaced because i had a leak and they were not worth fixing. This was on a wednesday. After checking around with other companies i had jack do the job and i had a whole new unit installed on monday. He got it done in about 7 or 8 hrs and it was quality work. I went with him for this job due his honesty and price. Use HVAC Jack and you will not be disappointed."

"Bill is awesome! This is the first time I've used him. He answered his own phone (first call), was able to squeeze me in the same day I called, and showed up on time. He fixed a gas leak, fixed an exhaust pipe from the furnace, and fixed the upstairs A/C. He also helped me get our gas log fireplace started, which hasn't been on in years. Another Bonus: he fixed the instant hot water machine under the kitchen sink! Bill was very knowledgeable and honest. He was careful, thorough, and took the time to explain everything to me. I will definitely keep him on speed dial. Thank you Bill!"

FAQs for furnace / forced air heating system install or replace projects in Kingsport, TN

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.
