Frequently Asked Questions
What metrics matter most on an HVAC technician resume?
First-time fix rate, calls completed per day, customer satisfaction score, inspection pass rate, and any energy-efficiency or sales figures make your bullets stand out to hiring managers.
Should I mention specific equipment brands in my bullets?
Yes, if the job calls for them. Naming brands like Carrier, Trane, or Lennox shows relevant experience, but keep it honest and only list systems you have actually worked on.
How do I write HVAC bullets if I mostly do maintenance?
Quantify units serviced per year, contract renewal rates, breakdown reductions, and efficiency gains. Maintenance work is very measurable and shows reliability employers want.
