Central Air Conditioning System: What Can Cause It Not To Work & The Cost Of A Replacement

Posted on: 10 February 2015

Are you using a window air conditioning unit because the central system is not working? It is in your best interest to get the central air conditioning system fixed because a window unit can cause higher energy expenses. In this article, learn the possible reasons why your central air conditioning system is not working and how much a replacement may cost if you need it.

What Can Cause a Central Air Conditioning System to Stop Working?

The main part of a central air conditioning system is the blower, as no air will flow through the ventilation system without it. If the blower is the reason your air conditioner is not working, it may be because dirt and debris has accumulated on the motor. You can ask a specialist to clean the motor for you to see if it resolves the problem, as attempting to clean it on your own can be complicated due to it being hard to access.

If the ventilation system has a good flow of air but it does not get cool, the problem may be within the evaporator coil. You cannot receive cool air without the evaporator coil turning the system coolant into a gas. The reason the gas is needed is for making the metal of the evaporator cold enough to cool warm air as it passes through the ventilation system. Dirt can pile up on the evaporator coil and prevent warm air from touching the metal, so the coil must be cleaned by a specialist.

If you are dealing with a central air conditioning unit that has simply worn down because it is old, you may need a new one. Investing in a new central air conditioning system is better than continuing to use a window unit because you won't have to run it for a long time. Window units are also not safe because they sit in a window and make it easier for burglars to get in your home.

How Much Does a New Central Air Conditioning System Cost?

You can expect to pay an average of $3,500 to $10,000 plus for a new central air conditioning system. However, it will depend on if new ducts are necessary and the size of your home. The age of your home can also play a role in how much you will have to pay. Contact an AC service and repair specialist to find out if your system is in need of a repair or if it should be replaced.
