Our Process

Call and Get on the Schedule

Reach a local team member and tell us what your system is doing. Same-day service is usually available, we hold a two-hour arrival window instead of a vague afternoon, and you get both a text and a call when your technician is en route to your Atlanta home.

Approve Your Flat-Rate Price Before Work Starts

We diagnose the system, explain what we found in plain language, and quote a firm flat-rate price. The number we give you is the number you pay, with no hourly billing and no surprise charges. Approve the repair and the diagnostic fee comes off the total.

Comfort Restored and Backed in Writing

We complete the work, test the system, and clean up behind us. Every job carries our 100% satisfaction guarantee, and our Self-Assurance maintenance plan keeps efficiency high while putting you first in line for future service.

One Marietta HVAC Team for Heating, Cooling, and Air Quality

Most Marietta homes need the same handful of things done well: a furnace or heat pump that starts every time, air conditioning that keeps up through August, and air that does not aggravate allergies. Self Brothers Heating & Cooling covers all of it. We repair, replace, install, and maintain heating and cooling systems across Marietta, including furnaces, heat pumps, and complete air conditioning systems, and we improve indoor air with whole-home air cleaners and humidity control. Emergency breakdown or planned upgrade, the process is identical: a real diagnosis, a flat-rate price, and technicians who finish correctly the first time.

What Your Neighbors Are Saying About Us

After getting several quotes on a full HVAC system replacement, I went with Self Brothers because they had some of the best prices and the best reviews. Spoke with the owner, John, and he was able to work me in on the day I needed. Luis, Miguel, and Luke showed up right on time and did the full replacement in a day. They cleaned up afterward and even sent me a video on how to use the new thermostat. Great experience, highly recommend.

As a new home owner, I’m very glad I chose this company for basic maintenance. Justin was punctual, polite, and so helpful. I had a lot of questions, as I basically had 0 knowledge about HVAC systems, and he answered everything throughly. I’m happy to continue their membership plan because I know we’ll be in great hands once it’s finally time to replace the units.

Joey & Luke came out to install our new HVAC system, they were amazing! The process was quick and efficient. They explained the new system and answered any of the questions I had! Would recommend - the process from inspection to scheduling and install was stress free especially in these HOT Georgia temperatures.

Brothers, Not a Franchise, Behind Every Marietta Service Call

Two brothers started this company in 2000, and after twenty-five years it still runs that way. No franchise fees, no faceless brand, no rotating cast of subcontractors. Our technicians are factory-trained and NATE-certified, every one is drug-tested and background-checked, we are an Authorized Carrier Dealer, and we are BBB-accredited with an A+ rating. We built our reputation keeping high-traffic Metro Atlanta businesses comfortable long before we knocked on a residential door, which means we can engineer a solution instead of just swapping a box. Our name is on the truck in your driveway.

Frequently Asked Questions

What HVAC services do you provide in Marietta?

Heating and cooling repair, replacement, installation, and maintenance, covering gas and electric furnaces, heat pumps, and central and ductless air conditioning. We also handle indoor air quality with whole-home air cleaners and humidity control.

Do you offer same-day and weekend HVAC service?

Same-day service is usually available on weekdays, and Saturday and Sunday appointments can be arranged by request. We are not a 24-hour call center, so the earlier in the day you reach us, the better our chances of getting to you before evening.

How does your pricing work?

Flat-rate. You get a total price before work begins and that number does not change, because we sell the service rather than the hour. No hourly billing, no charges for supply runs, and the diagnostic fee is waived when you approve the repair.

Do you service equipment you did not install?

We do, on all major brands. Our technicians are factory-trained across manufacturers, so you do not need to track down whoever installed the system originally.

What areas around Marietta do you cover?

We serve the Metro Atlanta area, including Marietta, Smyrna, Decatur, Roswell, Woodstock, Dunwoody, Norcross, Acworth, Austell, Mableton, Powder Springs, Alpharetta, Canton, Lawrenceville, Newnan, Peachtree City, and the surrounding communities.
