"We were able to schedule same-day service for a furnace that had stopped heating. Technician called 45 minutes ahead of arrival, and arrived on time. He checked furnace, identified the problem, and solved it in a few minutes. Furnace started and ran properly. We have a service contract with Cool-Ray and have used them continuously for over 20 years for all our home heating and air conditioning services."

"I live in Cherokee County and my tech is Jerry Cobb. He is AWESOME! My heat went out last night (2/27). I called the company at 9 am and they immediately dispatched Jerry. He met me at my house at 10:21 am. After a few questions he went to work. A very thorough inspection of the furnace, diagnostic performed and voile furnace fixed and humming like a Swiss watch!!! ALL at no cost because of my service warranty.? I am never leaving this company and hope Jerry never leaves as well."

"Omega Heating went under the house, changed out of the filter, and reignited to the pilots. He mentioned in the next year I would need to replace my furnace because of rust, which was great advice. They voiced their concerns, which I was grateful for. They provided me an estimate for a replacement. I would recommend them to anyone. They were professional, on time, and went above and beyond."

"I did a quote on Angie needing help with my newly installed HVAC system in my recently purchased home. Kevin was the first person to call me, I explained what was going on he asked a series of questions and eventually referred me to the installer of the system. Informing me there should be a minimum one year installers warranty, to figure out whom installed it and to get them back out as to not void my manufacture warranty by allowing someone else work on the system. I received and used information from my broker and the same day 4/24/26 called the original installer and they are coming today 4/28/26 to fix this brand new system. The Peoples Champ Heating & Air, will be my go to experts once this courtesy one year warranty is up for sure. Thanks Kevin. For being a honest decent person, caring more about your craft and building relationships then making a Buck."

"Rockey helped us select the units that would work best for us. We decided to go with high quality units, which would qualify us for higher rebates, besides giving us greater energy savings. Rockey was very pleasant to work with. His company installed both systems and repaired some damaged ductwork. We are very pleased with the results and the much improved comfort level of our home!

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