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.

Right-Sized AC Replacement and Installation for Marietta Homes

A new air conditioner only performs as well as the design behind it. Our Marietta air conditioning contractors evaluate your existing system, ductwork, registers, and controls before recommending equipment, because an oversized unit short cycles and an undersized one never catches up in Georgia humidity. Whether you are adding cooling to an existing furnace, swapping out an aging central air conditioner, or putting in a complete system with new ductwork, we build it around your house. We install energy-efficient central air conditioning and ductless options, and we provide a competitive written estimate for every Marietta home we quote.

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!

Installed by the Crew Marietta Businesses Trusted First

We spent our early years building multi-zone systems for Metro Atlanta retailers and restaurants, where a mistake shows up as an unhappy customer within the hour. Homeowners get that same crew. Our installers are factory-trained and NATE-certified, every technician is drug-tested and background-checked, we are an Authorized Carrier Dealer, and we are BBB-accredited with an A+ rating. Before we leave, we verify airflow, confirm the system is holding proper temperatures, and walk you through operation, filter changes, and warranty coverage. Twenty-five years of work still standing in Marietta homes is the only reference that really counts.

Clear Numbers on a New Marietta Cooling System

A new air conditioner is a real investment, so we make it easy to evaluate. Estimates on new systems are free and written, pricing is flat-rate rather than hourly, and the number we quote is the number you pay. We schedule around your household, protect floors and walls while we work, haul away the old equipment, and register your manufacturer warranty for you. Qualified installations carry a 10-year parts and 10-year labor warranty, and financing is available through the Wells Fargo Home Projects Credit Card. Call Self Brothers Heating & Cooling for a straight estimate on your Marietta home.

Frequently Asked Questions

How do I know what size air conditioner my Marietta home needs?

Sizing comes from a load calculation, not a guess or a match to whatever was there before. We measure the home, evaluate insulation, windows, and ductwork, then size the equipment to the actual cooling load so it cycles correctly and controls humidity properly.

How long does an AC replacement take?

A straightforward changeout is typically completed in a single day. Jobs involving new ductwork, electrical changes, or relocated equipment can run longer, and we give you the expected timeline before we start rather than after.

Can you add air conditioning to my existing furnace?

In many cases, yes. If your furnace and blower are in good condition and correctly sized, adding a matched outdoor unit and coil is often the most cost-effective route. We inspect the existing equipment first and tell you honestly whether it makes sense.

Do you handle permits and removal of the old unit?

Yes. We pull required permits, remove and dispose of the old equipment, and handle refrigerant recovery according to code. You do not need to coordinate any of it.

What warranty comes with a new air conditioning system?

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