A central air conditioning system can be very convenient when someone is excessively hot and need access to cool air in a speedy manner. When a central air conditioner is running at its best condition, it can usually cool a house down within a matter of a few minutes. However, it is uncommon to turn the system on expecting it to cool the house down, only for warm air to start flowing from the vents. Unless a homeowner accidentally turned the heater on, there should be no warm air coming out of the vents when trying to cool a house down. The content below explains what the problem might be in such a situation and why you should contact an air conditioning technician if you want a fast resolution.
There Are Problems with the Condenser Coil
When a house doesn't cool down after an air conditioner has been running for a while, it is sometimes due to warm air being circulated rather than cool air. When the warm air isn't the result of the heater being on, it is simply room temperature air that is unable to be routed out of the house. Basically, in order for the warm air to be routed out while the air conditioner is running, there must be a functional condenser coil in place. A technician can inspect the condenser coil to find out if it is dirty, damaged, or completely worn out and needs to be replaced.
The Refrigerant Level Isn't Sufficient
Refrigerant is another aspect of a central air conditioner that might need attention if there is only warm air circulating in a house. However, it isn't usually necessary to replace refrigerant on a regular basis, as it is able to last on a long-term basis in most cases. If there is a refrigerant problem, it can be due to none being placed in the system for several years and needing to be recharged, or there might be a leak in the refrigerant line. A technician can check the refrigerant level and determine if there is a leak in the line that needs attention.
Not Enough Cold Air Flows from the Vents
It is possible that your central air conditioner is producing cold air, but only a small amount of it is coming out of the vents. The problem in such a case often stems from there being something wrong with the ventilation system. You can get the air ducts inspected to find out if there is anything in them that is blocking airflow, or if a repair is needed.

Hello. My name is Josiah. I am a 44-year-old married dad of three. I work in the automotive industry and love what I do. Recently, my heating and cooling unit stopped working. I did a lot of research on what type of heating element I should install in my home. I wanted something energy efficient, yet reliable and lasting. After a lot of research, I settled on a heat pump. A heat pump is a great heating and cooling element that many people don't yet know about. I created this blog to help educate other people on heat pumps and answer questions related to it. If you need a new heating or cooling device for your home, I hope my website helps explain to you what a heat pump is and how it can be beneficial.
