DIY vs professional: safety line

Some hvac repair tasks are safe DIY in Boise; others are illegal or dangerous without a licence:

• Safe DIY: filter changes, thermostat batteries, clearing surface debris, resetting breakers.
• Pro only: anything involving gas lines, refrigerant, major electrics, structural openings, or pressurised systems.
• Grey zone: component swaps — if a licence or certification is legally required, DIY voids insurance and warranties.

When in doubt in Boise, pay for a diagnostic visit. It costs far less than a botched repair.
