How To Install An A/C Unit

16 May

ac_installationBe very careful when you pick up and move your new air conditioner.  You must get a partner to help you carry the unit.  Be sure to use proper bending and lifting techniques to lessen back strain.  Watch carefully for sharp edges that can cut your fingers.


Warning:  If you decide to install your air conditioning unit note that highly dangerous, electrical voltage could cause accidental injury or death.  Ground the unit and follow all local electrical codes and follow all instructions to avoid poor connections.  Loose wiring may cause overheating and could start a fire.


If you live in an area where with high winds anchor the outdoor unit with bolts and a secure metal frame while providing a suitable air baffle.  If you live in a snowy area and you have a heat pump type of system you must raise the unit up on a platform that is higher than snow drifts and provide adequate vents for snow.


AC installation does require the right equipment and safety procedures before you begin. Check the unit instructions to find out what tools you need. Many window units will not require you to have anything major, but an evaporative cooler is a different story.


Take your unit out of the packaging and test it before you start installing it. If you notice any missing parts, call the manufacturer. You should also review the instructions before starting installation. This will show you any issues relating to installation (such as window size, etc). There may be additional items you need to purchase. Most window units are designed to sit on the window sill and ledge, but some homes may not have one that is large enough. In this instance, you need to consider using an installation kit. These kits contain a small metal bar that you must secure to your window to hold the A/C unit.


It is extremely important the unit slightly tilts outside. This will help any water to leak outside, versus inside. Water should run through the coolant system without leaking, but it is common to see dripping if a system is over-used.


Lock the unit in place with the brackets that are given with the system. If you have a larger window, you may want to use wood or purchase an extension kit to the unit. This will prevent the hot air from seeping into the home. It also prevents a large hole on the side of the unit, where spiders, flies, and other insects can easily get into the home. Use caulking around the unit to seal off any small cracks or holes. This is also necessary to help the unit remain secure in place during the winter. If you choose to keep the unit up year-round, caulking is necessary.
