In my case, it turned out that I needed 11 louvers, spaced 3 1/8 inches apart to fill the 36 inch span: I settled on 45 degrees since that allowed me to obscure the view of the a/c best with the least disruption of air flow (plus the math was easiest!) Next I calculated how far apart I wanted my louvers to be and what angle I wanted them to be. enough talk about A/C efficiency! I am sure you want to know how I built it.įirst I measured how tall I wanted the screen to be and cut (4) 1x3s to form the vertical supports for the louvers. Each A/C unit has it's own clearance requirement, so make sure you check before installing ANYTHING nearby. ![]() I also made sure to install my panels 12 inches away from the actual air conditioner, which is the minimum clearance suggested by the manufacturer. Since the louvers are spaced far apart and are angled upward (the direction of the air flow) the air flow resistance is minimal. since it allows for a decent amount of airflow and offers a little disguise.īecause air is sucked in from the bottom of the unit and blows out via the large fan at the top, that is also why this louver design works so well. That is also why you frequency see lattice around them. You should never put bushes, a plant trellis, fence or anything solid around your A/C for just that reason. What am I talking about? Because the purpose of the A/C condenser is to suck in air and run it over the cooling coils (as fast as possible), if you put anything around the outside (or over the top of) your A/C you force it to work extra hard and greatly lower its efficiency. The beauty of this design is that it meets the manufacturer’s requirements for clearance and doesn't impede air flow to the unit. ![]() SOMEDAY HAS COME!!! Check out my version: When I tore it down back in 2012, I was left with a spiffy new pergola post and a whole lot of ugly air conditioner (which I am always paranoid about since I worry the kids will throw something inside of the fan or even stick their fingers in!):īack in that original post I had an inspiration photo for what I wanted to build “some day”: It was pretty bad (I’m glad ithat sucker hadn’t tipped over!)Īt that time I also removed a rotten trellis that surrounded the nearby A/C unit (of course I didn’t take a photo of it at the time, so here is my ever so fancy artist’s rendering:) Back in 2012 I shared my experience replacing a post on our pergola that had suffered termite damage.
