What a tune-up actually includes

The checklist our techs work through twice a year, so you can tell a real service visit from a filter change.

Written by Zak, Service manager

Heating, in the fall

  1. Combustion analysis with a meter, so we know the burner is running clean and efficiently
  2. Heat exchanger inspection for cracks and corrosion
  3. Clean the flame sensor and check the igniter
  4. Test every safety control: limit switch, pressure switch, rollout switches
  5. Check the draft and venting
  6. Measure gas pressure and temperature rise
  7. Replace the filter, or show you how if you prefer to do it yourself

Cooling, in the spring

  1. Measure refrigerant performance with gauges and temperature readings
  2. Clean the outdoor coil and check the indoor coil
  3. Test the capacitor, contactor and electrical connections
  4. Clear and test the condensate drain
  5. Check airflow and temperature drop at the registers

What you get afterward

A written report with the readings, photos of anything worth watching, and a note on any part that is close to failing. Nothing is replaced without your approval.

Signs it was not a real tune-up

Common questions

Is twice a year really necessary?

For a system that heats and cools, yes. Heating and cooling use different parts, and each season’s failures show up in the opposite season’s check.

Does a tune-up keep my warranty valid?

Most manufacturers require proof of regular maintenance for warranty claims. Our report is that proof.
