Quick answer
To find the right trade, identify the core component causing the issue: water or drain lines require a plumber; high-voltage wiring or panels require an electrician; heating, cooling, or ductwork require an HVAC tech; roof coverings require a roofer; and structural wood framing requires a carpenter. Use this tool to match your symptom and view adjacent confused trades.
What this assumes
- Trade matches reflect standard state licensing jurisdictions and trade scopes across North America.
- Complex issues (e.g. water leaks affecting electrical panels) may require sequential involvement of multiple licensed trades.
- Safety hazards like gas smells or electrical sparking take precedence over trade selection.
Important
If your issue involves natural gas odors, active electrical sparking, or structural sagging, take safety precautions immediately before scheduling service.
Understanding the result
Navigating overlapping trade boundaries
Many common home issues span multiple trades. For instance, a tankless water heater involves plumbing (water supply and pressure relief), electrical (240V circuit), and HVAC/gas fitting (venting and gas lines). Calling the right trade first saves diagnostic service call fees.
Electrician vs. HVAC Technician
If your AC outdoor unit won't turn on, an HVAC technician diagnoses the contactor, capacitor, or compressor. However, if the main breaker trips repeatedly or the disconnect box melted, an electrician handles the supply panel circuit.
Plumber vs. Handyman vs. Water Restoration
A licensed plumber stops active pipe leaks, clears main sewer lines, and replaces fixtures. A handyman can handle minor faucet washers or drywall patching. If water has soaked floor joists or insulation, a water restoration specialist is required.
Roofing vs. Carpenter vs. Mason
A ceiling stain near a chimney could be flashing failure (roofer) or degraded chimney brick pointing (mason). If roof rafter framing has rotted beneath the leak, a carpenter is needed for structural repair.
