Skills that raise your rate

• Diagnostics

  Finding the fault rather than swapping the part is the difference between an entry rate and a good one.

• Propane and gas appliances

  Furnaces, water heaters, fridges and stoves. Safety critical, so fewer people do it confidently.

• Solar and lithium battery systems

  Growing fast as more owners live in their vehicle full time, and few technicians have caught up.

• Water damage and structural repair

  Roof leaks and delamination are the most common serious failure, and the repair is skilled carpentry.
