"We recently had our HVAC system replaced by CoolRay Heating and Air and were extremely pleased with the entire experience. Mike Ritchey, our sales representative, conducted a thorough evaluation of our existing system and clearly presented several replacement options tailored to our needs. He was knowledgeable, responsive, and worked diligently to provide a competitive and fair price. The installation was led by Rollin Tappin, who, along with his team, demonstrated professionalism and care throughout the process. They completed the work safely, efficiently, and with great attention to detail. The new system is functioning perfectly, and we greatly appreciate the high level of service delivered by both Mike and Rollin. We would confidently recommend CoolRay Heating and Air to anyone in need of HVAC services."

"I was referred to Paze Heating and Cooling by a well-respected friend, and I immediately understood why. I have referred this company to several others and will continue to do so. Mr. Zeno Pace and his team are expert technicians. His responsiveness is very timely and his pricing is well worth the level of service he gives. I recently had an A/C problem that was covered by my home warranty company. Mr. Zeno helped me understand and articulate the repairs needed so that I would not be taken advantage of by the other contractor. Ultimately, I was taken advantage of by the other contractor, and Paze Heating and Air came to the rescue. Mr. Zeno responded immediately and fixed the damage the other contractor left. You will not go wrong with Paze Heating and Cooling."

"The company is fantastic! I had both full systems installed (condenser and furnace) after one of our units broke down. Jeremy came out to give me a quote and was extremely kind and professional. He made observations about changing some configurations in order to help with airflow and cleaner air. They worked us in early since they knew we were down a system in the heat. Two gentlemen worked diligently to get both systems done ahead of schedule! After the system was installed I had some things I wanted changed with airflow and someone came out the next day to address my concerns. Bethany in the office is extremely helpful and responsive as well! Great team and will use them now for our yearly maintenance too!"

FAQs for furnace / forced air heating system install or replace projects in Mableton, GA

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.
