They worked so hard on a hot summer day! It was 96 degrees out. My attic is small and cramped. There was a freaking HEAT ADVISORY today with heat index values up to 109 expected. My AC condensation line was clogged, and wouldn’t budge. The team went the extra mile and stayed a long time to fix the issue. These guys are amazing.

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.
