How can you use a portable air conditioner without an exhaust hose? A portable air conditioner does not work without an exhaust vent; however, it is possible to minimize the hose length by installing vent similar to the one used for a dryer to exhaust the unit. Portable air conditioners work by moving heat from the room and must vent to cool. Why must a portable air conditioner have a hose? All air conditioning systems require a connection to the outside to remove heat from an area. With central air conditioning and window units, the system transports the heat to the evaporator coils outside using refrigerant. With the portable unit, the evaporator coils are inside the home. A fan pushes air through the coils and vent to the outside. Air is less efficient at transporting heat than refrigerant. This makes portable air conditioners less efficient at cooling than either window units or central cooling systems. Portable air conditioners are small units on wheels that allow the owner to move them to the desired location for use.

Once in location, the hose connects to a port on the back of the air conditioner. The easiest way to exhaust the system is to connect the hose to a sliding window using the small expanding panel the venting kit supplies. For casement windows, owners often choose a plexiglass panel to replace the window glass for venting. However, the dryer vent connection allows the user to hide the hose behind the unit without blocking a window. Do all portable AC units have vents? A portable air conditioning unit requires a vent because it needs some way to remove heat from the room it is cooling. Without a vent, the unit simply disc... How do you clean an indoor air duct? An indoor air duct can be cleaned by removing the vent from the wall and vacuuming dust from the vent and the air duct with a vacuum hose or brush. What is an exterior exhaust vent? An exterior exhaust vent circulates air, moisture, grease, steam and smoke to an outdoor area of a home or business. Exterior vents are often attached to m...

Get an energy-efficient, portable evaporative cooler Evaporative coolers, also called swamp coolers, combine the natural cooling properties of water with a steady breeze to lower indoor temperatures.

This guide will help you determine which type is best suited for your needs. Tip: Evaporative coolers are most effective in areas of low humidity and hot temperatures. They can be used as the sole cooling system, or to complement existing air conditioning systems. They should never be used at the same time, however, as evaporative coolers add humidity and A/C units remove it. SHOP ALL EVAPORATIVE COOLERS How Do Evaporative Coolers Work? Evaporative coolers lower indoor temperatures by combining the natural cooling properties of evaporating water with an efficient air moving system. Evaporative coolers add moisture, with the water-filled pads acting as a filter, removing dust and allergens from the air. Evaporative coolers offer several benefits over air conditioning, including: • Lower installation and maintenance costs • 75 percent less electricity usage • Helps prevent fabrics and wood from drying out • Can be powered by standard 120 volt outlet

• No ozone damaging refrigerants Evaporative coolers are not as controllable as air conditioners, and can use between 3.5 and 10 gallons of water per hour, a consideration for use in areas with limited water supplies. Evaporative coolers are typically distinguished by where they are installed and the type of pads they use. Most whole-house evaporative coolers are mounted on the roof and blow air downward, while others are mounted through windows or walls and blow air in from the side. Down-flow installations are most popular, but window/wall-mounted horizontal units are more convenient for maintenance and reduce the chance of roof leaks. Both down-draft and window-mounted units blow cooled air into the house either into a central location, which is effective for small homes, or through existing or specially installed ductwork in larger homes. Tip: To ensure effective distribution, you’ll need to know how much air the unit needs to move to cool your home, which is measured in cubic feet per minute.

• Cools small spaces up to 300 sq. ft. • Can cool one room or a garage • Installed on roof • Discharge cool air downward into the structure • Typically installed on side of building directly into the attic area • Can be installed on roof using an elbow to direct the airflow through opening in roof The two types of pads for evaporative coolers are fiber (made of various materials) and rigid media pads. Fiber pads are inexpensive but require more maintenance and replacement, while rigid media pads are more expensive but require less maintenance and may last for years if properly maintained. • For units with inlets on many sides • Usually 1 to 2” thick • Require regular maintenance/replacement • Aspen wood is most durable; • Cellulose and synthetic may be cut-to-fit Stacked corrugated sheet material • For units with single inlets • Require larger upfront investment • Usually 8 to 12” thick

• Allows air to pass through at lower velocity, resulting in increased humidity and air a few degrees cooler than with fiber pads • Extremely long lifecycle if maintained For the most cooling power, you’ll need to know how much air the unit needs to move to cool your home, which is measured in cubic feet per minute. Evaporative coolers are rated by CFM. Use this formula to calculate the CFM for cooling your home: Determine the square footage of space you want to cool. Multiply this figure by the height of your ceilings. Divide that number by 2. The result is the CFM rating for the evaporative cooler you need. Keep the rust- and corrosion-resistant galvanized steel that most whole-house evaporative cooler housings are made of intact with monthly inspections. Regular maintenance per the owner’s manual is the best way to keep your evaporative cooler working at peak efficiency. Maintenance is usually centered on draining water to remove mineral buildup, and adjusting the belt and water levels.
