Choosing the right air conditioner unit, when central HVAC may not an option, involves several factors. To determine what type of air conditioner to buy, consider the following questions: You may also need to factor in the ease of installation and the energy efficiency the AC unit offers. Types of air conditioners vary depending upon the window space available. hung sash window that opens up and down typically can accommodate a standard window air conditioner, while a slider/casement style AC unit is needed for casement windows that crank open or slide open horizontally. These types of indoor air conditioners sit on the window sill with the window partially open, held secure in place by the window sash and/or other manufacturer recommended methods. The chassis is the supportive frame for a window air conditioner unit. Units built with a slide-out chassis can be removed and may be installed through a wall inside an air conditioner sleeve (which may require brackets for support.)

Certain in-wall AC units can be installed so they sit flush with the wall, creating a sleek, minimalistic look. In-wall and slide-out chassis air conditioner units don’t have the same side-vents a regular window air conditioner has, but they do offer a high cooling capacity ideal for bedrooms and offices. Note: The thickness of your wall will determine if installing an in-wall air conditioner is possible. BTUs, or British thermal units, are units of energy. Cooling is measured in BTU per hour. According to Energy.gov, “Based on size alone, an air conditioner generally needs 20 BTU for each square foot of living space.” On average, most window AC units or portable air conditioners range from 5,500 BTU per hour to 14,000 BTU per hour. You may also see units with a cooling capacity size of a ton. A ton, in air conditioner cooling terms, means that unit has a rate of 12,000 BTU per hour. While the size of the room is key in figuring how much BTU is needed, don’t forget to consider how much sun or shade the room receives, the effectiveness of the room’s insulation and the height of the ceilings — it takes more energy to cool a room with 9-foot or higher ceilings.

Tip: When buying a window air conditioner, avoid one that is oversized (too high BTU) for the space. Use a BTU calculator to figure the right size for the space. A portable AC unit is an ideal choice if your room has only one window or a window AC unit isn’t permitted by your landlord. Consider a portable air conditioner for rooms that need supplemental cooling, such as offices, enclosed porches or loft rooms. You can find units with timers, multi-fan settings and that are easy to move from room to room as needed. Trust P.C.

Edit ArticleHow to Clean Split Air Conditioners These days almost every household needs some form of air conditioning, often the split ductless air conditioner.

This system is so compact, so energy efficient, and so low cost that most new homes are now pre-installed with it. However, these devices are small, so cleaning them can be a daunting task. What's more, having them cleaning professionally can be ridiculously costly, costing as much annually as 25%~35% of the cost of a new system. low power ac dcHence, here is a set of DIY instructions for anyone who wants to clean their air conditioning units and get back the strong cool airflow of a brand new air conditioner. ac unit installation costBe sure to read the warnings at the bottom first to avoid electrocution, and in my opinion it is essential to remove the front cover and clean inside it to avoid mould reinfecting what you have cleaned!small air conditioner for a room

Buy an aircon wash bag. Buy a good coil cleaner. Avoid the foam type coil cleaners because they can be messy and spread foam everywhere. Foam sprays also may not penetrate the coils or rotor fan blades properly. So stick to liquid solution sprays. Beware of buying harsh chemical cleaners that are designed to attack organics, as they may damage newer air conditioners. Newer split air conditioners often come with their cooling coils coated with a blue-colored hydrophilic layer (which keeps the condensation flowing over the coils easily to improve airflow strength). Install the aircon wash bag around the split a/c unit (called an FCU-Fan Coil Unit) on the wall. Start spraying the chemical solution over the coils. Spray the rotary blades hidden in the outlet of the airflow. Wait for 10 to 20 minutes for the cleaning solution to work. Wipe down the fan coil unit. Be gentle and try not to exert too much pressure when brushing the cooling fins. They do bend and collapse easily under too much force.

To avoid or clear a drainpipe clog, spray some coil cleaning solution into the drainpipe. Then flush water down the drainpipe. If you can reach the other end, use a wet shop vac to suck out and clear the drainpipe. This should be done especially if you have a leaking air conditioner. Use the long reach nozzle or a toothbrush to push the rotary blades round to get at all the blades. If you know how to remove the front casing of the air conditioner, you can clean the coils more thoroughly. If your sprayer is strong enough, the pressure alone will cause the blades to rotate, as long as you focus the spray on the lower third of the rotor facing you. Before you begin, you can remove the drain plug from the drip tray in your aircon unit to allow all the dirt to drain into the wash bag instead. This can avoid letting too much dirt flow into the drainpipe. A used toothbrush can be very useful in dislodging and scrubbing some of the stubborn spots on the coils and everywhere else, especially areas near the airflow outlet.
