"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 found Cool Air via web search for AC Tune Up. They were offering a $39 system check which worked for me. Setting the appointment was very easy and straight forward. Jerry came out the next day and called 30 minutes prior to arriving. He was gloved masked and had booties covering his shoes before entering my home. He was very knowledgeable and made a number of no pressure recommendations and system additions that I didn't feel compelled to have installed. Jerry's approach was more as a consultant vs service person. I like this and would use Cool Air in the future."

"Ragsdale services our HVAC system since 2008. Their excellent service record gave us the incentive to include them in a bid with 4 participants. Despite negotiating during a heat wave, Ragsdale's Chris Boyd came through with a winning efficient 2-stage system proposal in one week. We thank the LORD that we will continue to do business with Art Ragsdale's most competent staff. --- Rev. Rob, USMC veteran"

"I woke up to a freezing cold house and was able to book an appointment for a repair that same afternoon. Rashad had the issue with my furnace resolved within 30 minutes. He was friendly and professional and took time to explain the problem to me and to show me exactly what steps he took to fix it. I will definitely call him again if I have any more issues with my heating and ac!"

"It was really good to have someone there who was socialble and willing to explain any questions we had. Even explained very well about the ac and how it works. Very reliable and the price was very reasonable and the quality of work was great. Came after hours and got to work on our unit quick and was done in no time. I will definitely hire them and the gentleman that did the work again when I replace my furnace and a/c. Thank you so much."

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