Technically, there is no official list of air conditioner brands, but there have been many unofficial accounts of the preferred brands for both quality and efficiency. Two brands that consistently rank in the top five air conditioner brands are Carrier and Trane because of their long-standing reputation for excellence. There are many great air conditioning brands to choose from, though, and I think these the ones below are some of the best on the market.

One of the oldest and most prestigious companies in the air conditioning industry is Lennox. Established in 1895 Lennox has been designing new technologies for over two decades. All of the Lennox models are very cost effective and operate efficiently and greenly. Lennox has established themselves as one of the top manufacturers of heating and cooling technologies in the industry.

S-Series Wall Mounted: These are top-of-the-line air cooling split systems appropriate for any house or commercial property. In addition to their cooling properties these machines will double as heating systems and they will also control humidity levels in whatever room they're mounted in. Finally the S-Series will also disinfect mold and bacteria from the air to purify it, meeting every conceivable air quality need with a single device.

Trane is another excellent phoenix air conditioning manufacturer who sells direct. The Trane Company was first incorporated in 1913 by father and son James and Reuben Trane. Trane is one of the first companies to incorporate integrated controls into their products. You can operate a Trane unit from your cell phone remotely to save on costs and only run it when you need to. It is also a very green friendly company.

One big advantage of American Standard air conditioners is the way they are set up for cooling. These units have two compressors that make multiple stages of cooling possible. The cooling compressors are specially designed so that they are durable and last. American Standard air conditioners create high energy savings because of the type of compressors that have been installed. Customers can decrease their energy bill by as much as fifty percent when using these units in their home. Heating and cooling can be performed at varying speeds and each unit has an air filtration system that keeps the air clean and healthy.

If you're looking for a more affordable yet still powerful and efficient phoenix air conditioning system than you should consider Hitachi's summit line of units. These are wall mounted, they are split systems and they offer a huge range of power levels to choose from, all the way up to 9.3kW. They're quiet, they can be programmed on timers, they are energy efficient and they might not be as slim as the Shirokuma models but they still avoid the obtrusive nature of most affordable air conditioners.

Why should you choose these phoenix air conditioning units over any other brand? The advantages they provide are abundant. These units can make cooling your home easier and more affordable. They have the highest ratings among HVAC brands and have been proven to have the least problems. So many times homeowners go with the lower price or get talked into buying a unit that ends up being a disappointment. The result is costly repairs and inefficient cooling. Air conditioning is a large investment for any home and nothing is worse than to spend a lot of money on something that breaks down consistently or wastes money every month.

Choosing the right air conditioning brand can seem overwhelming, but if you do a little legwork, it's really not. Make sure you review the different air conditioning brands in order to find the best fit for your individual purposes.
