Most 'tune-ups' are a filter swap and a sticker. Ours is a measured inspection — static pressure, charge, airflow, combustion — that catches the small problem before it becomes a no-heat or no-cooling emergency.

A real HVAC tune-up is a measured inspection, not a quick filter swap. Anderson checks and cleans the coils, verifies the refrigerant charge to spec, measures static pressure and airflow, tests the capacitor and electrical, clears the condensate drain, and — on heating — inspects the burner and heat exchanger and checks combustion. Service it twice a year (spring AC, fall heat). It pays off by keeping the system at its designed efficiency, catching cheap repairs before they become emergencies, and protecting your warranty.
A lot of what's sold as a tune-up in this trade is a filter change, a quick look, and a sticker on the unit. That doesn't tell you whether your refrigerant charge is correct, whether your ducts are choking the airflow, or whether a weak capacitor is about to leave you with no cooling on a 95-degree afternoon. A tune-up is only worth paying for if someone actually measures the system.
Twice a year is the standard: a spring AC tune-up before the Calhoun summer and a fall furnace or heat pump tune-up before winter. A year-round heat pump benefits from both. Between visits, the single most valuable thing you can do is change your air filter on schedule — a clogged filter starves airflow and is behind a surprising share of the breakdowns and high bills we see.
Done honestly, yes — in three ways: it keeps the system at the efficiency it was designed for (a dirty coil or low charge raises your bill every single month), it catches cheap repairs before they become expensive emergencies, and it protects the manufacturer's warranty, which often requires documented maintenance. Because we measure, we show you the numbers instead of just saying it 'looks good.' And if your system genuinely needs nothing, we'll tell you that too — that's the building-science way.
Spring AC or fall heat — we'll check the real numbers and tell you honestly what your system needs.

It bundles your two seasonal tune-ups into a membership, usually with priority scheduling and a repair discount. It's worth it if you'd otherwise forget to book or want the warranty documentation handled. Ask us to run the math for your specific system before deciding — no pressure.
