A strong clear logo with a technical font that underlines the importance of the material - Aluminum metal. The symbol carries the importance of: window, door, sun, lighting - hence communicating this to the presumptive client/viewer.
I think the name "CONNER" is so strong that it would be a pity to tune it down to "CA". Imagine the name by itself on products and on buildings "C O N N E R" - it can easily become a concept, synonymous with aluminum products.
Whereas "CA" is more anonymous.
"What kind of window did you buy?" "I bought CONNOR aluminum!" vs ("I bought CA windows!")
