I am not your technician, contractor, or engineer, and nothing in this video is professional HVAC, electrical, or mechanical advice. No professional relationship is created by watching. HVAC systems are dangerous. They involve high-voltage electricity (208–240V) that can cause serious injury or death, capacitors that hold a lethal charge even after the power is off, pressurized refrigerant, and moving parts. Always shut off power at the breaker and verify it's off with a voltage tester before touching anything. If you are ever unsure or uncomfortable, STOP and call a licensed professional. Some work legally requires a licensed and certified professional — including anything involving refrigerant (which requires EPA 608 certification), your electrical panel, or gas. Laws and codes vary by location, and it is your responsibility to follow the ones that apply to you. Any work you perform on your own system is done entirely at your own risk.
