The specific heat of water is 1 calorie/gram Â°C = 4.186 joule/gram Â°C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation.
Central air conditioners typically last from 10 to 15 years. The lifespan of a central cooling unit may be reduced if its capacity is not properly matched to the cooling load of the home.
To test your central air conditioner, you must have the outside temperature above 60 degree Fahrenheit for a period of two days or 48 hours to be precise. Some manufacturers may even recommend a temperature of 65 degrees.
