My spouse decided to take on the installation of a window a/c, although she had no experience whatsoever in doing such a procedure. She assured myself and others that she had learn enough on the internet to figure out how to do it. I made the decision to give him our full support, although I had our doubts. I did a bit of research myself plus realized how much is legitimately involved. For example, when using support brackets to hold the a/c in place, the window sill should first be checked for rotting wood or other material. Otherwise, the a/c could fall right out. Also, no matter how strong the installation person, it is essential that another woman help lift plus hold the equipment in place since window a/cs are seriously heavy. One thing that I learn made myself and others chuckle, since it stated that the window plus the a/c should both be measured before making any purchases. I am quite confident that our spouse would guess that! Then there are sealing materials needed to prevent hot air (and bugs) from entering the room. Modern a/c’s come equipped with extensions to occupy the space between the equipment plus the window sash, however by filling the cracks with foam (or other Heating, Ventilation, plus A/C material), the a/c will operate much more efficiently…and you won’t have bugs coming in! One last thing that I learn made perfect sense, that the installed window a/c should be located within numerous feet of an electrical outlet. The article explained that most modern a/c’s come with a numerous foot long electric cord, however that adding an extension cord was unsafe. Thankfully, our spouse plus her sister ended up doing a fantastic job.
