Frequently Asked Questions
What is a soft-start kit?
A soft-start kit installed on an AC compressor can reduce the starting surge by 50-70%, sometimes allowing sizing down a full generator tier and saving hundreds of dollars.
Portable vs. standby generator - which should I choose?
Portable generators (2,000-12,000 W) run on gasoline and start manually. Standby generators (7,000-22,000 W) run on natural gas or propane, start automatically within seconds, and cost $3,000-$12,000 installed.
Do I need a transfer switch?
Most jurisdictions require one to prevent back-feeding power onto utility lines. A manual transfer switch costs $200-$600 installed; an automatic one costs $500-$1,500.
Can I run my central AC on a generator?
A 3-ton central AC draws 3,500 W running and up to 10,500 W starting. You generally need a 10,000 W or larger generator. A window unit (1,000 W run / 2,700 W start) is far more manageable.
