Download Your HVAC Troubleshooting Guide PDF (Electrical Focus)
You’ve checked the air filter. You’ve changed the thermostat batteries. You’ve made sure the vents are open.
And it’s still not working.
Most HVAC troubleshooting guides online are afraid to get technical. They tell you to "call a professional" the moment the problem goes beyond a dirty filter. But the reality is that over 80% of HVAC failures are electrical in nature.
If you are comfortable using a multimeter and following safety protocols, you don’t need to guess. You just need the right map.
Why Generic Guides Don't Work
Standard guides focus on airflow. But if your outdoor unit is humming without the fan spinning, or if the breaker trips the second the AC kicks on, you aren't dealing with an airflow problem. You are dealing with an electrical component failure.
To help you diagnose these specific issues, we have created a printable, field-ready cheat sheet.

What’s Inside The Guide?
We stripped out the fluff and focused purely on the electrical "gremlins" that actually stop your system from running.
In this free PDF download, you will get:
The Capacitor "Mushroom" Test: How to visually identify and test the #1 cause of AC failure.
The Multimeter Cheat Sheet: A quick reference table for what settings to use (VAC vs. MFD) and what numbers you need to see.
The "Silent System" Workflow: Step-by-step instructions for when your unit has absolutely no power.
Wiring Red Flags: How to spot "rub-outs" (short circuits) and burnt contactor pads.
⚠️ Safety First
HVAC systems utilize high-voltage electricity (240V). This guide is for educational purposes. Always turn off power at the breaker, thermostat, and disconnect box before opening any panels.
