"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 called R.Wiley, Heating and Air, and Leonard came out right away. Rather than immediately telling me that I needed to replace the system because it was so old, he searched first what the problem could be. He replaced a part, but it turned out that this was not going to work very well because my furnace was just too old. It helped a bit but it was only a temporary fix to keep the furnace going for a while longer. We then decided that I would have to replace the system. He did NOT charge me for the part or for the service call! The price he quoted for a new system, was very reasonable, and on top of that, he gave me a discount because I am a service contract client. Then, two days later, because of the very cold weather, my system decided to quit altogether on Saturday morning. I left a message on Leonards phone asking if they could come out the next Monday to install the new furnace instead of the Tuesday we had agreed on. He called me back a few hours later and told me that they had made some arrangements with the supplier of the furnace and that they would COME OUT THE NEXT DAY WHICH WAS A SUNDAY!!!! They installed the system on Sunday and in the evening my house was comfortably warm again! This is amazing service that you don't see very often! It made me bless the day I signed the service contract with R. Wiley Heating and Air a few years ago! I Can really recommend this company for its courteous, friendly, and professional service!"

"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed. From the moment the technician arrived, the experience was professional, thorough, and reassuring. They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands. What stood out most was their attention to detail—they didn’t just check the basics, they inspected the entire system to ensure my home was safe and up to code. No high-pressure sales, just honest advice and helpful recommendations. I’ll absolutely be using TE Certified again and would highly recommend them to anyone looking for top-tier electrical service."

"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."

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