HVAC Maintenance • Calhoun, GA
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.
Written by the team at Anderson Heating, Air & Insulation, serving Calhoun since 1978
The Short Answer
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.
What a Real Tune-Up Checks
Every visit is measured, so you see the numbers instead of hearing it "looks good."
Coils, cleaned and checkedA dirty indoor or outdoor coil can't move heat — it quietly raises your bill and can lead to freeze-ups or overheating.
Refrigerant charge, verified to specWe check the charge against the manufacturer's numbers by measurement, not by feel. Low charge is a slow leak you want to catch early.
Static pressure and airflowThe one most companies skip. High static pressure means the system is fighting restricted or undersized ducts.
Electrical and capacitorA weak capacitor is cheap to replace on a tune-up and a common cause of a mid-summer no-start.
Condensate drainA clogged drain backs up water and can shut the system down or damage your home.
Burner, flame sensor & combustionOn furnaces we inspect the heat exchanger and check combustion for safety.The Problem
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.
How Often
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.
The Payoff
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.

The goal is catching the cheap problem before it becomes an emergency.
