"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.""

"We recently had the pleasure of working with Mountain Comfort Heating & Air and I can confidently say this was one of the best service experiences I’ve ever had. Owner Josh Jenkins is the definition of professionalism, knowledge, and integrity in the HVAC industry. From the moment he arrived, it was obvious he truly understands his craft at an expert level. Josh took the time to thoroughly diagnose the issue instead of rushing to a quick fix like many companies do. He explained everything clearly, answered every question with patience, and made us feel completely confident in the work being performed. His attention to detail, workmanship, and pride in what he does are absolutely exceptional. What really sets Josh apart is not just his technical ability, but the way he treats people. He genuinely cares about his customers, their comfort, and doing the job the right way the first time Thank you Josh!"

"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!"

"I asked them to check my dryer vent/hose hookup for connection. They cleaned the lines and connected the hose to the back of dryer. They also hung and readjusted the bi-fold doors to my laundry room. They both were very knowledgeable and professional in their work. I plan on having them to come back and do some more projects soon. I highly recommend this business without hesitation."

FAQs for furnace / forced air heating system install or replace projects in Johnson City, 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.
