Window or Room AC Buying Tips

Buying guide for window type air conditioner:

Now a day’s people are seeking to more energy efficient home appliances as the demand of energy is increasing. In this respect people are preferring window air conditioner than their central air conditioner due to its energy saving property.

Most window air conditioner is installed vertically in the room wall. Sometimes it is installed in windows with some modification. Like all other air conditioner window air conditioner has the parts named a compressor, a condenser, an evaporator, an expansion valve, a filter, a thermostat and a control panel. The working principle is also same like other conventional air conditioner like portable or central air conditioner.

Efficiency evaluation:

If you need to cool two or three rooms then you should definitely go for a window air conditioner. Because the initial cost of window air conditioner is low and is usable to long time with less maintenance cost. To buying an energy efficient room air conditioner you have to be familiar with a term called EER. EER may be defined as how many BTUs are required to cool a room using one watt of electricity. So everyone should buy room air conditioner having higher EER. The higher the EER value the higher the energy efficiency of the air conditioner.

While choosing a room air conditioner you must have to meet the exact amount of BTUs for the required space. If BTUs become more then the required amount then your cooling space will be dummy. On the other hand if BTUs become less then the required amount then the air conditioner will loss more electricity to cool the space and work overtime. So its an important factor to be considered while buying a room air conditioner.

Can really a portable Air Conditioner Save Money?

Yes definetely, a portable air conditioner can save money because of following reasons:
  • Portable air conditioners are freestanding mobile air cooling units and need simple installation that costs much less as compared to window or split AC.
  • Portable air conditioners are energy efficient and save money on your electric bill.
  • Portable air conditioners are very easy to install and do not require money to changes your home interior.
  • Portable air conditioners need less repairing and maintenance and saves money.

Portable Free Standing Air Conditioner

The demand of portable air conditioner's demand is increasing day by day.Air conditioning is demand of a hot and humid summer day. In addition to cooling, air conditioners also dehumidify and filter air, making it more comfortable and cleaner. Portable air conditioners also referred to as mobile air conditioner, have gained popularity over recent years.
There are many factors why portable air conditioners are in great demand:
A portable air conditioner is small and mobile and can be carried anywhere.
  • A portable air conditioner is not a through the wall AC unit and can be placed or installed anywhere.
  • A portable room air conditioner is a small free standing room air conditioner and is easier to maintain.
  • A portable air conditioner can be easily stores when not needed.

Installation and Location of Air Conditioners

If your air conditioner is installed correctly, or if major installation problems are found and fixed, it will perform efficiently for years with only minor routine maintenance. However, many air conditioners are not installed correctly. As an unfortunate result, modern energy-efficient air conditioners can perform almost as poorly as older inefficient models.

Be sure that your contractor performs the following procedures when installing a new central air conditioning system:

  • Allows adequate indoor space for the installation, maintenance, and repair of the new system, and installs an access door in the furnace or duct to provide a way to clean the evaporator coil

  • Uses a duct-sizing methodology such as the Air Conditioning Contractors of America (ACCA) Manual D

  • Ensures there are enough supply registers to deliver cool air and enough return air registers to carry warm house air back to the air conditioner

  • Installs duct work within the conditioned space, not in the attic, wherever possible

  • Seals all ducts with duct mastic and heavily insulates attic ducts

  • Locates the condensing unit where its noise will not keep you or your neighbors awake at night, if possible

  • Locates the condensing unit where no nearby objects will block the flow of air to it

  • Places the condensing unit in a shady spot, if possible, which can reduce your air conditioning costs by 1%–2%

  • Verifies that the newly installed air conditioner has the exact refrigerant charge and air flow rate specified by the manufacturer

  • Locates the thermostat away from heat sources, such as windows or supply registers.

If you are replacing an older or failed split system, be sure that the evaporator coil is replaced with a new one that exactly matches the condenser coil in the new condensing unit. (The air conditioner's efficiency will likely not improve if the existing evaporator coil is left in place; in fact, the old coil could cause the new compressor to fail prematurely.)
