Russell heating unit

Does anyone know anything about a Russell electric heating unit? Or a Russell company that manufacturers them? Or anything else about a Russell heating and cooling?

I’m looking for manufacture date and tonnage on this unit:

Model number MLD400L44
Serial number G9854775-011



This website under “products” tab claims they make split AC units, I don’t know if this is what you are looking for but it might help

Thanks, Steve.

I emailed them to see if they manufactured it and can provide any information.

Manufacturer is Russell Coil out of Brea, California.

Here’s the information they sent me: About Homes
