Hi I have an old Kelvinator air conditioner in the brickwall of my house which sits inside the familyroom and the exterior section is outside in the carport,(which you have to make sure you don't bang your head on it).Once this is taken out i will have a double brick wall on both sides to fill.Inside is not too much of a problem as i can fill the brick wall and paint it after.However the outside is an issue as the bricks are old (35yrs) i will have a job getting the same brickes to match.I know i could render or paint it but i am looking for other ideas about how i could just fill it with something that could look ok. Thank you
