Common Questions about Window Air Conditioners Published May 27, 2010 | Updated August 5, 2015 A great way to beat the heat is by installing a window air conditioner in your home or office. Using individual air conditioners and heaters in your home can take the load off of your central heating and air conditioning system, providing you with significant energy savings over the course of a year. Here are some frequently asked questions about window air conditioners and how you can use them in your home. Shop Air Conditioners & Heaters ▸ Will window air conditioners work in any window?Window air conditioners are built to fit multiple window types, including those that open vertically or horizontally. Many window air conditioners include adjustable panels, which help them expand to fit and seal most window openings. Be sure to measure your window and compare it to the air conditioner dimensions. What is a "SEER" rating?The SEER rating is a rating of window air conditioner efficiency.

The higher the SEER rating, the more BTUs of cooling power your window air conditioner creates for every watt of power. SEER ratings are calculated by dividing the number of BTUs by the watts used per hour. How much energy does a window air conditioner use?To calculate your window air conditioner's energy use, divide the BTUs by the SEER rating. Divide that by 1,000 to get kilowatt hours (kWh), which is probably how your electric company calculates your energy bill. You can then multiply the kWh by your power company rate to learn your costs per hour. For example, a 12,000 BTU air conditioner with a SEER rating of 10 and a cost of 25 cents per kWh would calculate as follows: 12,000 BTUs / SEER 10 = 1,200 W = 1.2 kWh 1.2 kWh x $0.25 = $0.30 per hour to run your window air conditioner. At 8 hours a day for 125 days of summer, your window air conditioner will have an annual running cost of $300 a year. How often should I clean the air filter?Usually, window air conditioners need new filters every three months.

If you live in an area with a lot of dust or pollen, you may want to replace it more frequently. Clogged air filters can impair the performance of your window air conditioner and increase your energy costs. 5 used & new from Ships from and sold by Seasonal Deals.

Product is too loud and i do not believe is energy efficient. I missed the date on returning item. My boyfriend can't sleep because it keeps him up at night. Quick tips for choosing an energy efficient air conditioner Choosing the most energy efficient air conditioner Did you know that heating and cooling appliances can use up to 40% of your household energy? It’s important that you do your research before buying one as choosing an energy efficient air conditioner will help you save on energy bills. To avoid buying a model that’s unsuitable for the space, it is recommended that you seek professional advice and calculate the cooling load using an online calculator to work out your cooling requirements before deciding on a model. Buying an air conditioning that’s unsuitable for the space would mean the room won’t cool properly or energy will be wasted. Bigger isn’t always best – a big air conditioner in a small room uses more power turning on and off than a small unit running for longer.

For small rooms less than 20sqm, a portable unit works well, but this air conditioning model doesn’t suit larger rooms. For rooms less than 50sqm, a window wall unit is sufficient, but these model is less energy efficient than a fixed split system. For areas larger than 50sqm, a split system air conditioner is the best option. A thermostat and/ or a timer gives you the ability to control the room temperature for maximum comfort and bill savings. The thermostat should be located in a frequently used room, away from the heating and cooling unit. Some air conditioning models automatically switch off when the desired temperature has been reached to save energy. Each extra degree of air conditioning can increase the running cost by up to 10%, so set the thermostat at the highest comfortable temperature to minimise energy use and maximise your bill savings. Some models can heat and cool to keep you comfortable all year long. Portable desktop, floor, tower, or table models can easily be moved from room to room, whereas the fixed fans are installed in ceilings or walls.
