Our 21-point HVAC inspection checklist
When Marietta HVAC Pros performs a seasonal tune-up, our licensed technicians inspect and measure every critical component.
Tighten electrical connections
Prevents loose wire arcing and premature component failure.
Measure motor voltage & amp draw
Ensures motors run within manufacturer safe specifications.
Inspect contactors & relays
Checks for pitting, burns, or sticking electrical contacts.
Test capacitor capacitance
Verifies start/run capacitors are within operational microfarad ratings.
Signs your system is overdue for a tune-up
Catch small operational inefficiencies before they turn into complete summer breakdowns.
Rising electric bills without usage changes
Dirty coils and improper refrigerant force compressors to run twice as long to reach set temperatures.
Sticky indoor air & high humidity
When cooling cycles short-run due to uncalibrated controls, your system fails to pull moisture out of Marietta air.
Hot and cold spots across rooms
Clogged filters, weak blower motors, or unbalanced dampers leave back bedrooms uncomfortable.
Short cycling & unusual noises
Frequent clicking, rattling, or rapid cycling points to failing capacitors or dirty thermal switches.
How Marietta humidity and pollen impact your HVAC
Summer in East Cobb, Smyrna, and Kennesaw brings severe humidity averaging over 75%. When outdoor coils coat with spring pine pollen and indoor coils lack proper refrigerant charge, your system cannot dehumidify effectively.
Regular spring tune-ups clear heavy pollen layers from outdoor condensers, restore proper subcooling levels, and protect your compressor against heavy July and August thermal loads.
