What an HVAC Maintenance Visit Actually Includes

If you've ever wondered whether a tune-up is real work or a sales visit with a clipboard, here's the actual checklist — item by item, and why each one matters.

If you've ever wondered whether a tune-up is real work or a sales visit with a clipboard, here's the actual checklist — item by item, and why each one matters.

A real maintenance visit is measurement work: a technician cleans what's dirty, tests what wears, measures performance against spec, and leaves you a written record. It takes about an hour per system. Here's what happens in ours.

What gets checked on a cooling visit?

• Condenser and evaporator coils inspected and cleaned — dirty coils are the #1 efficiency thief in the Valley

• Refrigerant charge verified against manufacturer spec

• Capacitors, contactors, and wiring tested under load — the parts that die in heatwaves

• Condensate drain cleared (the ceiling-stain preventer)

• Airflow and temperature split measured, filter checked, thermostat verified

What gets checked on a heating visit?

• Burners cleaned, ignition system tested

• Heat exchanger inspected — the safety-critical item

• Venting and combustion verified, safety controls exercised

• Gas connections checked, blower and airflow measured

How do you know it really happened?

The record. A visit that ends with numbers — static pressure, temperature split, amp draws — happened; a visit that ends with only a scary quote was a sales call. It's the difference we wrote about in how flat-rate, no-commission service works.

Ready to put your system on a schedule? Book a seasonal HVAC tune-up, or make both yearly visits automatic with a Gold or Platinum Maintenance Membership — here's the math on which makes sense. See the fall warning signs a heating visit is designed to catch.
