What size air conditioner do I need?

A larger air conditioner will not always provide more cooling. It should be sized for room area. If properly sized it should operate long enough to remove moisture from air. It is moisture removed from room which actually produces feeling of cooling. Unfortunately many people in their rush to purchase a window air conditioner buy too large a model.

Too large a unit can actually provide less cooling than a smaller, properly sized unit. This is because with an oversized air conditioner its run time is too short. Consequently it does not remove enough moisture from room to produce a feeling of comfort. If you’re A/C seems to cycle off and then back on every few minutes and does a poor job of cooling, it is probably oversized for room.

Air conditioners are rated in BTU’s. British Thermal Units are a measurement of how much heat is being transferred form room being cooled to where heat is dumped out of doors. This is why cooing coil inside room is cool to touch, while part that hangs outside is extremely hot.

A window air conditioner used in average household room can be as low as 4000 BTU. While 5000, 6000, and 8000 are most common sizes purchased.

How do I determine what size A/C I need?

Following is a basic sizing chart for calculating window air conditioner needed for a room. Calculate size of room by multiplying width of room by length of room. Use your room size to determine what BTU's are required to cool that particular room size.

Which is best room for placement of an air conditioner?

A router bit is a tool for woodworking giving a quality finish to woodwork. It cuts wood providing a way to give a clean and even a decorative edge to woodwork. The following is some basic information about router bits to get you started in your woodworking efforts.

The Parts of a Router Bit

Here are there main parts of a router bit: 1) The shank- part of router bit that is inserted into collet (the sleeve of router). 2) The cutting edge- this part cuts and removes wood. They are available in several sizes and shapes. 3) The pilot- guide for router in order to make a correct cut. It can be an extension of shank or a ball bearing attachment.

The Different Kinds of Router Bits

While there are over 50 router bit profiles, here are four basic types of router bits: 1) Grooving Bits- These bits make a groove in piece of wood. This type of bit is commonly used for street address signs for homes. Different types of grooving bits include V-Groove, Round-Nose and Straight Bits. 2) Joinery Bits- Router bits that help make several different types of joints. This type of router bit includes Finger Joint, Drawer Lock, Rile and Stile, and Dovetail Bits. 3) Edge Bits- Bits used to create different-shaped edges in woodwork. Examples of these types of bits include Beading, Flush, and Round-over bits. 4) Specialized Bits- These bits do not fit into one of above categories and have more specialized purposes including Key Hole, Raised Panel, and T-Slot bits.

Carbide versus HSS bits

Most of bits you will find available in hardware stores are carbide (short for tungsten carbide) tipped. These router bits are made of a very hard material that stays sharp longer than steel and is resistant to heat. However, this type of router bit can chip and is very expensive (this is why most of bits are tipped and not made completely of carbide).
