Amperage draw refers to the amount of electrical current a device uses while operating. It helps determine electrical safety and performance, and higher draws may require dedicated circuits or upgraded wiring.
Why is amperage draw important for HVAC equipment?
It confirms the circuit can safely power the equipment and helps spot issues like failing motors or electrical overloads.

Higher amperage means more current demand on the circuit.
Knowing amperage draw helps ensure the electrical circuit can safely handle equipment like water heaters and HVAC systems, preventing overloads.
Check amperage draw during maintenance to confirm equipment stays within manufacturer specifications.
“Check amperage draw during maintenance to confirm equipment stays within manufacturer specifications.”
The ampere is named after André‑Marie Ampère, a founder of classical electromagnetism.
How do I check amperage draw?
A technician uses an ammeter or clamp meter while the system runs to measure current safely.
What causes amperage draw to increase?
Dirty filters, failing motors, voltage issues, or restricted airflow can increase draw.
Does higher amperage mean higher efficiency?
Not necessarily. Higher draw usually means more power use, which can indicate inefficiency.
