Homeowners frequently ask our technicians: “Do I really need to have my air conditioner and furnace checked every year?”

The short answer is yes—ideally twice a year. In Georgia’s climate, where systems operate under high cooling loads from May through September and transition to heating during chilly winter spells, regular maintenance is the single most effective way to prevent costly surprise breakdowns.

The Twice-A-Year Rule: Spring and Fall

Because your HVAC system relies on distinct components for heating and cooling, an optimal schedule divides inspections into two seasons:

1. Spring AC Tune-Up (March – May)

Before summer heat waves hit Metro Atlanta, an air conditioning tune-up ensures peak efficiency:

  • Cleaning outdoor condenser coils to ensure unrestricted heat dissipation.
  • Testing capacitor electrical ratings and contactor condition.
  • Measuring subcooling/superheat and checking refrigerant levels.
  • Inspecting and sanitizing condensate drain lines to prevent summer clogs.
  • Verifying blower motor airflow and duct static pressure.

2. Fall Heating Inspection (September – November)

Before turning on your furnace or heat pump for the first cold snap:

  • Inspecting heat exchangers for hairline cracks that could leak carbon monoxide.
  • Cleaning burners and testing ignition assemblies.
  • Testing safety limit switches, thermocouple performance, and gas pressure.
  • Verifying defrost cycles and auxiliary heat strips on heat pumps.

What Happens When Maintenance Is Skipped?

Neglecting maintenance doesn’t just increase the odds of a mid-season breakdown; it quietly costs you money every single month:

  • 10% to 25% Higher Utility Bills: Dirty coils and restricted blowers force the system to run up to 40% longer to achieve the same indoor comfort.
  • Shortened System Lifespan: An unlubricated motor or straining compressor can shave 5 to 7 years off equipment life.
  • Voided Manufacturer Warranties: Nearly every major manufacturer (Trane, Carrier, Lennox, Goodman) requires proof of annual professional maintenance to honor parts warranties.

Simple Maintenance Steps Homeowners Can Do Themselves

Between professional visits, you can keep your system in top condition:

  • Change 1-inch air filters every 30 to 60 days during peak summer and winter.
  • Keep at least 24 inches of clearance around your outdoor condenser unit, trimming back bushes and vines.
  • Ensure indoor supply and return air registers remain unblocked by furniture or rugs.
