Get matched with top central a/c installers in Duluth, GA

"Top notch company - installed our new AC/Heating units two years ago. I was a bit pricey, but has performed flawlessly. Subsequent service calls have been reasonable and professional. Highly recommend."

"The company was fast, efficient. There was a small problem after installation, and the company responded with in an hour. The minor issue was resolved within 10 minutes. Yes, great company and I give them my highest recommendation."

"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!"

"The installation went really well"

"The installation team, Bryan and Bruce, treated our home with care throughout the entire process. They maintained positive communication with us and were consummate professionals. The install of our new system went smoothly. We highly recommend this company and this installation team for all applicable home needs."

"From the first call, meeting Jacki to the last follow up call, this company is 5 stars. The owner Steve came after hours to access my old equipment. They had a rare HVAC unit in stock and made time to install ASAP due to extreme heat outside and a young child. Jacki was not only empathetic, but was able to obtain the permits needed and the install was scheduled the next day! They arrived on time and everything went smooth. I recommend this company to everyone!"

"Very well. I was having the biannual inspection done of a system that Estes installed. I have had good customer service on each occasion and am extremely happy with the system they installed, which was a difficult job (new duct work on an older home as well)."
