Job Locations and Reviews
Air Conditioning System Repair: The homeowner reported the AC system was turning on and off frequently without fully cooling the home. Upon inspection, we identified a clogged condensate line triggering safety shutoffs and a weak compressor capacitor affecting system performance. Cleared the blockage, replaced the capacitor, and inspected the drain system for proper flow. After testing, the AC now runs consistently and delivers strong, reliable cooling throughout the home.
Preventative AC Maintenance: Completed a scheduled maintenance visit to prepare the system for heavy summer usage. Cleaned condenser coils to improve heat transfer, checked refrigerant levels, inspected electrical components, and replaced the air filter. Also tested capacitor strength and verified proper airflow across the evaporator coil. After a full system test, confirmed the unit is operating at peak efficiency and ready for continued reliable performance.
AC System & Indoor Air Quality Installation: The homeowner requested improved cooling performance along with better indoor air quality. Installed a new high-efficiency air conditioning system paired with an upgraded filtration system within the ductwork. Ensured proper system integration with the existing air handler, sealed connections, and tested airflow. After installation, we verified system performance and cooling output. The home now benefits from cleaner air and more consistent, efficient cooling.
Air Conditioner Repair: A homeowner reported their AC system would not power on at all despite thermostat adjustments. During inspection, we found a failed control board that was preventing communication between system components. Replaced the control board, tightened and inspected wiring connections, and verified proper low-voltage operation. Tested full system startup and shutdown cycles. The AC now powers on reliably and provides consistent cooling.
AC Maintenance & Repair: The homeowner reported inconsistent indoor temperatures and reduced cooling performance during peak heat hours. Inspection revealed a malfunctioning return air temperature sensor and slightly low refrigerant levels due to minor leakage. Repaired the sensor issue, performed a leak check, and recharged the system to proper levels. Tested system performance across multiple cycles. The AC now maintains steady indoor temperatures and operates more efficiently.
AC System Replacement: The homeowner reported loud operation, longer run times, and uneven cooling throughout the house. Inspection revealed a failing compressor along with multiple worn components, making repair no longer cost-effective. We removed the existing system and installed a new high-efficiency air conditioning unit, including a properly matched indoor coil. Charged the system to manufacturer specifications, verified airflow, and tested temperature split. The new system now cools evenly, operates quietly, and runs much more efficiently.

The two gentlemen where outstanding!! They were the most hardworking, focused, and polite people I have ever had in my home doing a HARD JOB in a incredibly small, cramped space! When they finished, they cleaned-up and showed us how to work and read the machines and you would never have believed that they had been here, for more than 6 hours, working nonstop!!! Thanks, The McDaniels
I am so impressed this company. From the quote and the details to the crew and the owner. My house is finally cool in my whole house.
Marcio Pereira is a wonderful representative for A Team. As a service tech he is extremely knowledgeable and very professional. He is conscientious and provides good customer support. I would HIGHLY recommend Marcio !!!
My issue was just two things that needed finished and Greg took care of them with flying colors!!
Greg installed 2 gas lines in very difficult conditions, with tight spacing and floor joists in the way. He was even able to take 10 minutes to diagnose a bad capacitor and fix it in the air-conditioning unit! Now we’re cooking with gas and cooling with AC! Thank you Greg.
Excellent service. Efficient, neat, and very polite!
At my rental property, heat stopped on the weekend. The A Team got it fixed at a very fair price.
Impressed I got an appointment the same day! Prompt, courteous service, on time and they clean up after themselves!
We were going to have insulation installed when Marcio found cracks on our duct work. He showed me the problem and they resolved that problem THEN installed the insulation - leaving at 7:20pm. Marcio is GREAT! Please let him know.
Very knowledgeable and personable, great service!
Have a maintenance contract with A Team and today, as in the past, I am very VERY HAPPY WITH the technicians. Today, my technician explained every area of each of my 2 units. He was very professional, came when expected, and answered all questions with confidence and ease. Bravo to A- TEAM!
We will continue to use your company. Great service OK I did that I did what was his name I forget Judy OBrien so I did two of them the non-mobile and this one may go do you by clicking submit

Thank you for taking the time to let us know how Angelo is doing!
Marietta , GA Heating & Cooling FAQs
We recommend AC tune-ups in the spring and heating maintenance in the early fall—twice a year total. Regular tune-ups include inspections, filter changes, refrigerant checks, lubrication, and more to catch small issues early, extend equipment life, improve efficiency, and keep your home comfortable through Georgia’s hot summers and chilly winters.
If your system is over 10-15 years old, experiencing frequent breakdowns, causing inconsistent temperatures, or leading to higher energy bills, replacement is often the better option. Even with great maintenance, age and wear can’t be avoided forever. A-Team Services offers expert installations, financing options, and energy-efficient upgrades to save you money long-term and ensure reliable comfort.
Georgia’s high pollen, humidity, and mold risks make indoor air quality crucial. We install air purifiers, air scrubbers, and whole-home systems to remove allergens, pollutants, and excess moisture. Combined with regular filter changes and maintenance, these solutions protect your family’s health, reduce allergy symptoms, and create cleaner, healthier air year-round.
