O2U - Air Solutions
The idea for the brand name is based on "Oxigen (O2)" + "to (2)" + "You (U)" = "O2U". The expression "Air Solutions" would clear any possible doubt about your company activity. I think that in a slogan it would also sound nice "O2U. Air Solutions made for you". In the Logo the "O" could be blue and the "U" red (In my opinion it makes sense due to the possibility of getting fresh air and some warm through your products/services). In a way the white and red combination can also be associated with the polish flag. Anyway, it's just my opinion. Hope you like and thank you for your attention.
