A key member in your household that often gets forgotten about unless it's not there is the humble air conditioner. While it may keep your home nice and cozy during the summer months it often fades into memory as winter takes its hold. However, if you neglect your outside unit you might find yourself in an unpleasant position when summer rolls around. Below are some helpful tips to keep your unit humming happily after the long winter months.

Winterize Your Window Unit

Winterizing your window unit can be quite simple. This is because smaller units can often be dismounted from the window and stored away until the next season rolls around. Just remember to store it in a dry place to avoid potential rusting.

On the other hand, if you are unable to remove the unit from the wall, you should take steps to mitigate moisture getting into the unit and having the potential of freezing or rusting out the inside of the unit. With this in mind it is wise to purchase a covering for your unit as well as make sure it is unplugged so that it doesn't whir to life during those odd warm days.

Winterize Your HVAC Unit

Preparing your outside unit requires a bit more work, but it is much more worth it as it is more susceptible to to the elements than a wall unit. Just like that stubborn wall unit that won't come free, the wisest first step is to locate your AC circuit. The AC circuit is located in either a metal or plastic covering. You do this for the same reason as you would unplug your wall unit, to keep your AC from running on those warm winter days so that water doesn't accumulate and potentially freeze which can damage the unit.

Secondly, it is wise to take a high powered hose and wash down your unit thoroughly before you seal it up. After letting it dry your next focus should be covering the fan portion of the unit to prevent and debris or moisture accumulating inside of it. This can be accomplished by grabbing some sturdy plywood and placing it on top of the fan. Put a weighty object such as a brick or large rock on top to keep it in place. Afterward you can use a large tarp and tie it off with bungee cords to stave off further assault from the elements.

Lastly, you should search for coverings for the pipes coming out of the unit to keep the insulated so they do not freeze and rupture. Typically simple foam coverings will do. After that, it's just a matter of routinely checking on the unit to make sure the tarp remains in place.

With these tips kept in mind, your AC should remain in good health and avoid expensive repairs in the future. For more information, contact an HVAC contractor like Tropic Air Conditioning INC.
