FAQ About A Problematic Central Air Conditioner

by Amelia Martin

Did your central air conditioning suddenly stop producing cool temperatures? The main part of the system that is responsible for cooling warm air down is the evaporator coil. There are several types of problems that can interfere with the functionality of the evaporator coil. It is also possible that your air conditioner is just old. Take a look at this article for the answers to a few of the questions you might have about a malfunctioning evaporator coil.

How Does an Evaporator Cool Down Warm Air?

The evaporator coil is able to cool down warm air because the metal that it is constructed out of is cold. Basically, when coolant is placed inside of the air conditioning system, it transforms into a cold gas. Coolant is simply a combination of antifreeze and water. The gas is able to make the evaporator coil cold enough to cool down warm air as it passes through. Warm air has to make contact with the metal of the coil in order for it to cool down.

Should an Evaporator Coil Be Cleaned On Occasion?

It is very important for you to make sure the evaporator coil is cleaned every now and then, especially if you use the air conditioner a lot. An accumulation of dirt in the coil is one of the main things that lead to a lack of cold air. Dirt is bad for the evaporator coil because it us like an insulator. The dirt prevents warm air from making proper contact with the cold metal. You can then end up with a limited amount of cold air in your house or none at all.

What Does it Cost to Replace an Air Conditioner?

If the lack of cold air in your house is due to your air conditioning system being old and worn out, you should expect to spend a minimum of $3,500 for a new one to be installed. However, the quoted priced is based on a system for a 2,000 square foot house. Whether or not your air ducts can still be used will have an effect on the price as well. The energy efficiency of the air conditioner that you opt for and complexity of the task will also be considered when you are charged for professional installation.
