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.

Complete Heating Service for Marietta Furnaces and Heat Pumps

Marietta winters are short but sharp, and a heating system that has sat idle for eight months does not always wake up cleanly. We service, maintain, repair, and install gas furnaces and heat pumps across Marietta, treating your heating equipment the way you would treat a vehicle you depend on. Regular maintenance protects performance and extends system life, and a proper inspection catches cracked components, ignition faults, and airflow restrictions before the first cold night finds them for you. Heat pumps deliver steady, efficient heat through a Marietta winter, and we service every major furnace and heat pump brand found in Marietta homes.

What Your Neighbors Are Saying About Us

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.

The whole team at Self is wonderful- I’m so glad to have them on my side for all things heating and cooling. They are great at explaining everything in a way you can understand, and giving you options for your needs. Appreciate the team and highly recommend getting your HVAC serviced with them

Matthew may have been one of the most thorough and respectful HVAC technicians I’ve worked with to date. He was highly communicative, knowledgeable, insightful, respectful and efficient.

Warm Home, Honest Number, No Waiting Around

Heating problems tend to surface at the least convenient moment, which is why same-day service is usually available across Marietta, with weekend appointments by request. Before any work begins you approve a flat-rate price, because we sell the service rather than the hour and never pad a bill for time spent. Estimates on new heating systems are free, and qualified installations carry a 10-year parts and 10-year labor warranty. Self-Assurance maintenance plan members get scheduled tune-ups and priority service when the first real cold snap hits. Call Self Brothers Heating & Cooling today.

Frequently Asked Questions

How often should a Marietta furnace or heat pump be serviced?

Once a year for a gas furnace, and twice a year for a heat pump since it runs in both seasons. Annual service is where small problems get caught cheaply, and it protects both efficiency and equipment life.

Do you service both gas furnaces and heat pumps?

Yes, along with electric furnaces. Our technicians train on all three, and we install and service every major brand across the Marietta area.

Is a heat pump a good fit for Marietta winters?

Marietta winters are mild enough that a heat pump runs efficiently through most of the season, holding steady indoor temperatures without the fuel costs of a gas system.

What are the signs my heating system needs attention?

Uneven temperatures between rooms, longer run times to reach the thermostat setting, unusual noises at startup, a burning or musty smell that does not clear, rising energy bills, and short cycling are all worth a service call.

Do you offer same-day and weekend heating appointments?

Same-day service is usually available during the week, and Saturday and Sunday appointments can be arranged by request. We are not a 24-hour operation, so reaching us earlier in the day gives us the best chance of getting to you before evening.
