These heat pump climate class ratings will be able to tell you if an air source heat pump unit matches up well with your particular climate. For example, most of the people in the world will end up using a T1-rated air source heat pump unit because they live in moderate climates. The air conditioners that come with a T1 rating will be able to handle temperatures up to 109 degrees Fahrenheit.

People who live in extremely warm climates will need to find an air source heat pump unit that is rated T3. These units will be able to function properly in temperatures up to 125 degrees Fahrenheit. People who live in colder climates who do not have to deal with the heat very often should look into T2 air conditioners. These AC units will only be able to handle temperatures up to 95 degrees Fahrenheit.

Choosing the Right Kind of Heat Pumps

If you are going to be able to choose the right air source heat pump unit for your own needs, then you need to check the heat pump’s climate class ratings before you make your final decision. If you are not aware of the maximum temperatures that are normally seen in your particular area, then you should probably do some research before you buy your new air source heat pump unit. If you find yourself debating between two different climate ratings, then you may want to go with the one that is more powerful. It always pays to be safe with your selection when you are choosing an air source heat pump unit based on its climate rating.
