What hiring managers check first

EPA 608 and other certifications

EPA 608 is legally required for refrigerant work. List the type (Universal is best) and any NATE specialties.

Callback rate

Service managers care about first-time fixes. A low callback rate is one of the strongest lines you can include.

Equipment range

Heat pumps, gas furnaces, ductless and commercial rooftop units call for different skills. Name what you work on.

Customer skills

Techs who explain clearly earn trust and maintenance agreements. Reviews or agreements sold prove it.

Mistakes to avoid

  1. Leaving out your EPA type

    Recruiters need to know whether you hold Type I, II, III or Universal. Be specific.

  2. Only listing installs

    If you want a service role, lead with diagnostic and repair experience.

  3. No numbers

    Calls per day, units installed and callback rate turn a list of duties into a record of results.

Questions

Do I need a state license to work as an HVAC technician in Tennessee?
Tennessee licenses HVAC contractors rather than individual technicians, though some cities have their own rules. EPA 608 certification is required everywhere for refrigerant work.
Is NATE certification worth it?
Yes for experienced techs. Many employers pay more for NATE-certified technicians, and it helps you stand out.
How long should an HVAC resume be?
One page. Put your certifications near the top so they are seen first.
