How Efficient Is A 220 Volt Air Conditioner for Your Home Cooling? Are you looking for a new air-conditioner? There is a wide variety of choices out there, but beyond brands and features, the voltage and horsepower are two factors you should be considering when choosing the right one. A 220-volt air conditioner might be appropriate for your home cooling needs if you want a central air conditioner, but be sure to check the cooling capacity, which is measured in BTUs (British thermal units), thermal energyâ€™s basic measure. The higher the BTU, the greater the ACâ€™s cooling power will be. Be mindful of the size, too, as a 220-volt air conditioner that is larger than your room will waste a lot of electricity. Ideally, you should pick an AC that is not too big and not too small for your room, so you can avoid uncomfortable hot and cold spots. Window air conditioners come as 110/120 volts and 220/240 volts, depending on the cooling capacity that you want. A small room may do well with an AC that has 15,000 BTUs, but if you need a larger unit, you will need a 220-volt air conditioner with a greater cooling capacity. If you are using the AC in the US, you may want to consider calling a qualified electrician to add a 220-volt circuit in your home. Certain features can make a 220-volt air conditioner more efficient, not just for home cooling, but for other purposes, too. If you have pets or allergies, you may want to consider an AC that comes with HEPA filters that are anti-microbial and easy to clean or replaceable, so you can ensure clean indoor air while enjoying efficient cooling. A high-quality 220-volt air conditioner will be durable and capable of cooling your home more efficiently, making it a worthy investment if you want to save money in the long run. Leading retailers of 220-volt appliances carry split-type, window, cassette type split, and central air conditioning systems from different brands like White Westinghouse (under Electrolux), Sharp, and Samsung. It is advisable to get a well-known brand that is known for their good customer service and after-service. Likewise, it is better to buy a high-end 220-volt air conditioner from a reputable seller that has good track record of providing high-quality products.
