Should I Hire a Handyperson for Baseboard or Wall Heater Installation?

Hire a handyperson for very simple, non-wiring tasks like replacing cosmetic covers. A handyperson is not the right choice for hardwiring, load calculations, or code-related work, and they do not perform in-depth electrical inspections. For new installations, wiring changes, or system concerns, choose an electrician or HVAC pro. For hydronic baseboards, hire a plumber.
