RV generators (except diesel and/or fleet generators, by specific exception)
Gasoline generators (except life-safety applications, again by specific exception)
Single-cylinder air-cooled residential standby power generators. These include Generac below ~10kW.
Any generator brand or type that has a history of being inherently unreliable. While AAAA can make most unreliable generators reliable, custom modifications and repairs can be cost-prohibitive.
Generators that would require illegal modifications to make reliable. For example, a design flaw that prevents the generator from starting
under certain barometric conditions (i.e. fuel mixture is too lean) would qualify because California prohibits modifying fuel
systems, making the repair this generator needs illegal. AAAA has identified this very condition in several single-cylinder engines.
As AAAA cannot legally provide the repair (and doesn't wish to be associated with generators that fail every time the wind blows),
AAAA's has simply discontinued support for single-cylinder residential generators.
Intentionally neglected generators. AAAA employs talented technicians who can repair just about any issue with just about any
generator so it wounds us to be asked to neglect a generator. We don't provide "service-by-repair" (neglecting a generator until it breaks) and we don't
offer support for generators where a reliability issue has been identified but its repair is declined.
There are plenty of local companies who will gladly take your money to rush to the site every time the power
is out and still will -not- repair your generator. AAAA Generator Services Inc is -not- one of those companies.
