Problematic HVAC Cooling System Parts

Although central air conditioning systems are some of the most efficient types for cooling a house down, they sometimes become problematic. Pinpointing the problems without the proper skills and knowledge concerning HVAC systems can be difficult to do. This is because there are numerous parts that work together to make the system functional. Problems can arise if any of the parts begin to malfunction, which is why you should hire a professional to get a comprehensive diagnosis. By browsing through the following points, you will learn about several of the most common issues that can cause an HVAC system to stop cooling efficiently.

The Primary Part for Cooling is the Evaporator Coil

A central air conditioning system must have an evaporator coil to assist with cooling warm air down. The coil is basically a piece of metal that is designed in a way that allows air to pass through. Air must pass through so heat can be removed and consequently cool down your house. The refrigerant that is used in a central air conditioning system makes the coil cold enough to remove the heat. Get your coil checked to find out if it is rusty, dirty, or damaged.

Too Much Dirt Inside the Air Ducts Can Cause Problems

The air ducts are an important aspect of the HVAC system for several reasons. For instance, the ducts are used for sending air into the rooms in your house that are equipped with vents. If the ducts are old, they might be damaged to the extent of air not being able to pass through without having to struggle. In some cases, air can stop flowing properly if dirt is creating a blockage in the ducts. A technician might need to clean your ducts out with commercial equipment if the air conditioner works inefficiently. 

The System Must Have a Working Thermostat

A working thermostat is needed for each part of an HVAC system to function so cold air will flow through the ducts. The thermostat is where the system turns on and signals the electrical panel to send power to it. If you are unable to hear any noise and there isn't any air flowing out of the vents, the thermostat is most likely to blame. Air conditioning contractors can find out if the thermostat needs replaced. Keep in mind that electrical problems can also lead to an HVAC system not turning on.
