A loud central air conditioning system that doesn't cool down a house in a timely manner can be a pain to deal with. No one wants to wait a long time for their house to cool down when it is hot, especially after having a long day at work or school. The fastest way to pinpoint why the air conditioner isn't functioning properly is through the professional skills of HVAC technicians such as Derek Sawyers Smart Energy Heating & Air. You might even find out that the system isn't worth repairing and that it is time to buy something new. This article explains several of the reasons why central air conditioning systems sometimes begin to function improperly.
The System Has Been Regularly Used
Regularly using a central air conditioning system places a substantial amount of wear on the important parts. The problem is even worse when you don't have a habit of getting maintenance for the system every once in a while. For example, when you have the system on every day, the blower fan has to rotate on a regular basis as well. Eventually, the fan can become loose, dirty, or stop functioning properly due to the blades getting damaged. The quality of a central air conditioner plays a role in how much wear it can take before causing cooling problems.
No Refrigerant for Removing Heat
Did you know that one important aspect of a central air conditioning system is for heat to be removed from the air? The cool air doesn't get produced simply from the blower fan spinning around. The system must have enough refrigerant to remove heat from the air as it goes into the evaporator coil. A central air conditioner is usually charged with refrigerant during the initial installation process, and it can last for many years to come. However, there is also the possibility of refrigerant being improperly charged or running low due to a leak.
Thermostat Temperatures Are Wrong
Thermostat temperatures must be accurate in order for you to cool down your house in a sufficient manner. It is a good idea to play around with setting the thermostat to different temperatures to find out if they are accurate or not. If you set a low temperature in an effort to obtain cold air, but heat comes from the vents instead, the thermostat likely needs attention. Recalibration of the thermostat by an HVAC technician might fix the problem unless a new one is needed.
