"Great! Got Infinity "urgent alert" emails saying "blower motor fault" though the furnace was heating and blowing. Coolray scheduled an appointment the next day despite being very busy. Darren arrived early, worked hard, discovered a loose wire, and fixed it. Thanks so much! And thank you to Coolray for the lifetime warranty on my HVAC system, which saves me tons of $$$!!!"

"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 Technician arrived on time. He wore a mask and shoe coverings. He explained to me what he was going to do to clean and service my two heating units. He also told me about a plan the company was offering where they would come out in the Spring and the Fall to service my AC and heating units. I liked the idea and the terms of the. agreement. I signed up and feel good that I have a reliable company that I can contact should I have a problem with my heating or cooling system!"

"I was struggling with a vendor who installed a new AC and furnace 3 years ago that required service every year. The Guardian team was able resolve the issue in 2 days at a fraction of the cost the original installer quoted. Technician Josh Bennett was able to isolate the problem in 30 minutes. He is very knowledgeable, personable, and very professional. HVAC Service Expert Dave Dover arrived the next day to complete the required repairs and washed the outdoor system. My wife and I could not be happier with Guardian service. We joined their Shield Protection Plan Membership."

"A giant shoutout to Atlanta Air Authority for coming to our rescue this week. We came home from being out of town on Sunday to a hot house. Our A/C unit was toast. Their quick response and fantastic service had us back up and running with a new unit within 3 days. Canâ t say enough good things about them. Definitely check them out next time you need HVAC service!!"

"Reliable, honest service, and fair prices. They just did a two-system replacement for us and it went extremely well. I've been working with Robby and his team for over 10 years on behalf of third-party clients and he is one of the most trustworthy contractors I've known. When I moved to the Atlanta area two years ago it was a no-brainer to hire R Wiley for my home's yearly HVAC maintenance package and I'm glad I did. We've had Miguel, one of R Wiley's outstanding technicians out for service and maintenance and I've been happy with his work and helping to diagnose issues. When it came time to replace our very old AC & Furnace units, there was no sales pressure - just consultative solutions. R Wiley's pricing was in line with some of the more affordable bids and they don't try to push you into super high-priced marked-up units or things that should be included with installation, or all those "financing" programs where you end up paying way more for your project. Installation with Marvin was awesome - they were done with two units in one day and what a difference it's made. Overall an awesome experience from day one, with a successful multiple unit replacement. I'm glad I have them to continue to keep the units serviced on an annual basis as well. Highly recommend!"

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