For areas with hot and humid weather conditions, an air conditioning that operates efficiently is not just a want but a need. Your home needs to have cool air all the time. However, if your unit has frozen up, you will not be able to live comfortably especially on a hot summer day. There are many reasons your unit will freeze up. Once you discover that this problem occurs, you need to call an AC repair Dallas technician to handle the problem. 

Why your AC freezes up?

Your air conditioning will start freezing up if ice is already covering the entire unit. There are many reasons why it happens. Units that are running for a long period of time usually experience this type of problem. The coil that is responsible for cooling can have a low freezing temperature. 

This is the reason why the condensation freezes or becomes ice. This is considered a problem because once ice covers the coil, it will be difficult for warm air to pass through. Your house will heat up as the cool air cannot enter. There are troubleshooting steps that you need to keep in mind in the event your unit freezes up. 

If you live in an area where your cooling system requires to work overtime, it is important that the cold air does not escape through the leaky doors and windows. There is no way that your unit can keep up if it is not working efficiently. In the evening, the outdoor temperatures start to drop. Your coil will also have trouble working once it reaches the freezing point. This happens when the condensation increases, causing ice to build up. 

The cooling system does not have enough coolant

Your air conditioning will frequently freeze up if it has leaking coolant. The coolant can either be in the form of gas or liquid. Its purpose is to get rid of heat. The lack of coolant can cause your cooling system to freeze up. If your air conditioning has a leak, the coolant will also disappear from your unit because it no longer has enough fluid to eliminate the heat. If there is lesser heat being absorbed, the coil will also drop, causing ice problem to occur. 

The air flow from your unit is reduced

Another reason your air conditioning freezes is when the warm air has trouble flowing over the coil. Due to this problem, the temperature of your coil will also drop below the freezing point. Once the moisture starts to freeze, layers of ice will start to form over the cooling coil. So if there is warm air, your cooling system will have difficulties in converting them into cold air. 

Thus, your house will suffer from extreme heat and other potential disasters. You can easily avoid this problem by scheduling an appointment with an HVAC technician. Regular maintenance is essential because aside from performing a thorough inspection, the technician will also fix any existing problem. A unit freezing up is a common occurrence but because some homeowners choose to ignore it, the problem becomes bigger. 

Troubleshooting your air conditioning 

Nothing can be more frustrating than discovering your unit is no longer working. The first thing you have to do before you troubleshoot the problem is to turn your air conditioning unit off to defrost the ice. Keep in mind that this is an important step because ice can be harmful to your cooling system.

If you are not comfortable dealing with minor issues, you can call an HVAC technician to inspect your unit. There are different components of your air conditioner that should be checked such as your air filter, evaporator coil, and ductwork.  It is also possible that your cooling system is freezing up because of a low refrigerant level. 

A licensed HVAC technician can recharge or refill your refrigerant. There might also be a problem with your refrigerant lines or blower fan. You should avoid buying a new air conditioner unless you have your unit checked by a technician. It might be a simple problem that just needs immediate attention. A frozen air conditioner will not fix itself. You need to hire someone to troubleshoot the problem. For your cooling system to run for years, it needs to be in tip top shape. Be sure to call a licensed technician to fix the unit.
