A customer’s HVAC system was running, but airflow was weak. After testing, we found a burned-out blower motor. Replacing it improved airflow and system performance. If your system isn’t circulating air properly, a faulty blower motor could be the issue.
This heat pump was stuck in cooling mode due to a bad reversing valve. Replacing the part restored both heating and cooling functions. If your heat pump isn’t switching modes, it may need a professional repair.
This customer’s AC wouldn’t turn on. After diagnosing, we found a failed start capacitor—a common issue in older systems. A quick replacement got their cooling system running again. If your AC won’t start, it could be a capacitor or compressor issue.
Today, a homeowner reported weak airflow and high energy bills. The issue? Clogged air filters restricting airflow! Regular filter changes improve air quality, efficiency, and system lifespan. Check and replace your air filters every 1-3 months to keep your HVAC system running properly.

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.
