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.
Notes: This was the second of 2 units in our (21 year old) home to fail. We chose this 2-stage central air conditioner since the salesman said it would work better and cut our electricity costs. Took a crew of 3 workers 5 hours to complete the installation for us.
