No. Anyone can clean the surface parts of a furnace or AC unit but only a licensed technician is able to inspect and judge the condition of key functional parts (especially those that have the most wear and tear), optimize gas pressure with a manometer, test CO levels with a combustion analyzer and take apart important compartments for an up-close examination and investigation.

Twelve-point service is primarily about making sure the unit is in good working condition and addressing any safety concerns that may become hazards. A 21-point tune-up is a more extensive investigation and analysis of potential issues that might impact how efficiently the equipment runs.
