Hide the Air Conditioner and Solder Copper Tubing for Air Conditioning
If you live in an old house or apartment building, your home may not have central air conditioning. Instead, you may have an air conditioning wall unit installed beneath a window. While these appliances can be quite effective at cooling your home during hot and humid summer months, they tend to be clunky, industrial-looking objects that can be quite an eyesore in your home.
How to Hide the Air Conditioner
Luckily, there is a simple way to conceal an air conditioning unit. Measure the width and depth of your air conditioner against the wall and write down these measurements. Go to a hardware store or lumber yard and purchase two 2-by-1/2-inch strips of wood cut to be 1 inch longer than width of your air conditioner.
Purchase another two strips cut to be 1 inch longer than the depth of the air conditioner. Sand each piece of wood carefully with 100-grit sandpaper. Dust them off with tack cloth when finished.
Position the pieces of wood together so they make a frame that will fit around the front of your air conditioner. Nail the pieces together neatly at each corner. Apply a coat of oil-based primer.
Once the primer has dried, apply two coats of paint, allowing the paint to dry between coats. Cut a piece of mesh or lace fabric that is 1 inch longer and 1 inch wider than the length and width of your air conditioner dimensions. Staple gun the fabric to the inner portion of the frame, inserting a staple every 3 inches or so, creating a 1/2-inch hem on the inner side of the frame.
Place the frame over the air conditioner to check the fit. Remove it. Make a mark with a pencil by the top right and left corners of the air conditioner.
Nail a 2-inch nail with a hammer at each pencil marking. Hang the frame on the nails.
How to Solder Copper Tubing for Air Conditioning
When you heat the pipe, sweat the solder onto the joint. Do not try to melt the solder into the joint. Solder copper tubing for air conditioners the same way you would any other copper pipe.
You need to know how to measure, cut and assemble the fittings before soldering. Buff the outside of the fittings, where they will make the solder connection, with emery paper until they shine. Clean the inside of the fittings with a round wire brush until shiny.
Apply a thin coating of soldering flux where the connections will be made, both inside and outside of the pipe. Assemble the tubing into the connectors. Light your torch for a flame about 1 1/2 inches long.
Heat the connector with the torch for about eight to 10 seconds, moving it a bit to heat the whole connector.
There are some general rules for soldering any copper pipe. Never solder pipe with liquid inside; always drain the pipes first. Clean the pipe; solder will only stick to bare metal, not dirt, corrosion or grease.
