If you have forced-air cooling but there's still a room that's hotter than all the rest, a duct or vent booster fan can increase the flow of cool air into that room. Two types of booster fans are available. An in-line duct booster fan fits inside the duct of the room you're trying to cool. You mount the fan near the outlet and it automatically kicks on when your cooling system runs. Vent and register booster fans sit directly on top of or replace ceiling, floor or wall registers. Depending on the model, you can set it to operate automatically, control it with a switch or operate it by a remote control. - Easy to install and use.In-line duct booster fans are available in both plug-in and hard-wired models and retail for $30 to $150. Vent and register booster units plug into a nearby electrical outlet or can be hard-wired. Register and vent duct booster fans cost $40 to $100. - Less powerful (and cheaper) in-line units have a lighter-gauge housing that is more prone to rattling.- Duct or vent booster fans may not make a significant cooling difference if your ductwork or overall cooling system is inefficient, sized improperly or faulty.

Wall air conditioners are less expensive than central air conditioning units, provide cooling capabilities of up to 18,000 BTU/hour, and can cool a room as large as 1,000 square feet. Some wall air conditioners are even large enough to cool an entire small house, provided that properly-placed, portable fans and appropriate insulation are used.

A wall-mounted air conditioner works in the same way as window air conditioners. Two fans blow air over hot and cold Freon-filled coils. The hot coils condense the Freon into a liquid, which then runs through an expansion valve and evaporates, which creates cold Freon gas. The cold gas absorbs warm outside air, cooling it and blowing it into the room to lower the room’s temperature. As a by-product of this process, the air conditioner also removes excess humidity from the room, making it feel even cooler and more comfortable. A wall-mounted air conditioner preserves your window view and allows you to open the window when it’s cool enough outside that air conditioning is unnecessary. Also, because wall air conditioners stay in place year-round, they offer easy, one-time installation. Finally, because it never leaves the wall, there’s no need to store a bulky AC unit in another location such as your attic or basement during the off-season. This makes a wall-mounted AC a particularly good option in regions that experience all four seasons.

Wall air conditioners provide more installation options than window units. Place a wall-mounted AC unit on any outside-facing, sheetrock wall that does not have any existing pipes or electrical lines running through it. With the help of a qualified electrician, it’s even possible to move electrical lines to accommodate an AC unit if necessary. Because the installer will have to cut a hole in the wall, a wall air conditioner cannot be mounted on a stone, brick, or concrete wall. Also remember to mount the unit near an electrical socket, as it has to plug into either a 115-volt or 230-volt household circuit, depending on the air conditioner size. A larger air conditioner requires its own circuit, while a smaller unit may share a circuit with smaller appliances (but not major appliances such as refrigerators and dishwashers). Unplug the AC when not in use in order to keep it from drawing electricity and raising your power bill. For the most energy-efficient cooling and cost effective air conditioning, look for wall air conditioners with an Energy Star rating.
