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.

New Heating Systems Sized and Installed for Marietta Homes

Replacing a heating system is the best chance you will get to fix what never worked right. Our Marietta heating contractors measure the house, evaluate ductwork and airflow, and match equipment to the actual load rather than to whatever happened to be there before. We install high-efficiency gas furnaces and heat pumps, including Infinity heat pumps recognized as a Consumer Digest Best Buy, and we handle precision installation of any major brand. Heat pumps pull heat from outside air even on cold Marietta mornings, delivering steady warmth at a lower operating cost than older equipment.

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.

We are so glad we went with Self Brothers for a recent system replacement. The team who came out went above and beyond what we have historically experienced with other HVAC companies in the area. Dwayne, Luke, Joey and Luis were extremely professional and worked efficiently to get our systems up and running in no time. 10/10 service

Over a number of years the Self team has been very helpful, from regular system checks to replacement needs. Kelly is great about scheduling and prompt with other communication needs. Today, Justin was here for a fall check-in. He was on time, courteous, and ensured all my questions were answered. Highly recommend this group!

Installation Quality Is the Part Nobody Ever Sees

Brand matters far less than the hands that install it. A quality furnace or heat pump put in carelessly will underperform for its entire service life, and we have replaced enough of those across Marietta to say it plainly. Our technicians are factory-trained, NATE-certified, drug-tested, and background-checked, and we commission every system before calling it finished, verifying airflow, temperature rise, and safe operation. We are BBB-accredited with an A+ rating and have been installing heating equipment in Metro Atlanta for more than twenty-five years, first for commercial buildings that could not afford failure, now for the homes around them.

Clear Numbers on Your Marietta Heating Upgrade

You should know the full cost before you commit, so estimates on new heating systems are free and written, and pricing is flat rate rather than hourly. There are no charges for supply runs or for the extra care a careful installation takes. We schedule around your household, protect floors and walls while we work, remove the old equipment, and register your manufacturer warranty for you. Qualified installations carry a 10-year parts and 10-year labor warranty, backed by our 100% satisfaction guarantee. Call Self Brothers Heating & Cooling for an honest estimate on your Marietta home.

Frequently Asked Questions

Should I replace my furnace with another furnace or switch to a heat pump?

It depends on your ductwork, your existing fuel source, and how you use the house. AMarietta winters are mild enough that heat pumps hold temperature efficiently through the coldest stretches. We lay out both options with real numbers instead of steering you toward one.

How long does a heating system installation take?

Most standard changeouts are finished in a day. Adding ductwork, converting from one system type to another, or relocating equipment can extend that, and we give you the expected schedule before work begins.

How do you determine the right size system for my home?

With a load calculation based on square footage, insulation, window area, orientation, and duct capacity. Oversized equipment short cycles and wastes energy, undersized equipment never catches up, so sizing is where the comfort of the whole system is decided.

Do you install all major heating brands?

We handle precision installation of any major brand. Carrier is our system of choice for reliability and durability, and we are an Authorized Carrier Dealer, but we will source and install other quality equipment on request.

What warranty comes with a new heating system?

Qualified installations carry a 10-year parts and 10-year labor warranty, so covered failures do not turn into service bills down the road. We register manufacturer coverage for you so it is active from day one, and we walk through exactly what qualifies before you sign.
