How To Repair Frozen Condenser

One of the well-nigh mutual HVAC issues is a frozen AC evaporator gyre, which will touch your Air conditioning'south ability to function properly. Fortunately, however, information technology is a relatively easy fix. The following is a cursory caption of the evaporator coil's role, the reasons evaporator coils freeze, and what to exercise to get your cooling arrangement working again.

What Does an Evaporator Practise?

Your air conditioner works by circulating refrigerant through two sets of coils or copper pipes. The refrigerant starts out as a liquid and is converted into a gaseous grade in the evaporator and evaporator coils. As it changes country, it absorbs heat. The gaseous refrigerant travels to the condenser coils where it changes back to a liquid again and releases the heat it contains. This process is how cool air is produced in both central air conditioning units and heat pumps.

In standard central air conditioning systems, the evaporator coil will be role of the inside components. In a rut pump, the evaporator can exist in either the exterior or inside unit of measurement, depending on whether or not the equipment is providing heating or cooling for your home. Outdoor coils serve equally the evaporator coils when the heat pump is generating heat.

Why Evaporator Coils Freeze

Evaporator coils can freeze for several reasons including:

• Cold coils: If the temperature of the evaporator coils falls below 32 degrees, water vapor in the air surrounding the coils will brainstorm to freeze when it comes into contact with the coils. At first, there may be but a thin film of ice or frost simply over time, a large coating of ice can build up.
• Low refrigerant: The refrigerant in your AC system absorbs rut. Depression levels of refrigerant, as a result of a leak for case, reduces the organization'due south ability to absorb heat, resulting in colder air passing over the coils.
• Malfunctioning defrost cycle: Cooling systems have a defrost cycle that helps keep frost and water ice from accumulating on the evaporator coils. This cycle most commonly works by temporarily reversing the period of refrigerant and allowing hot refrigerant to menses through the coils, melting whatever ice on their exterior. If the defrost cycle is malfunctioning, it may non exist able to remove ice and frost on the coils.

Fixing a Frozen Evaporator Coil

A coating of ice on the evaporator coils will prevent the coils from working properly. Since they are no longer in contact with the surrounding air they will not exist able to absorb that estrus, and air coming out of the supply vents will be warm. This will interfere with the cosmos of absurd air for indoor comfort. For such a project, it is best to contact your local HVAC professional. Your technician volition generally:

• Turn off power to the air conditioner to ensure it has stopped operating – for condom reasons.
• He will demand to open the access door to the evaporator coils and bank check to see if there is ice on the coils.
• If the coils are in fact frozen, at that place are a number of simple remedies your technician can use to get rid of accumulated ice. Information technology is important to note that chipping or hammering at the water ice should never exist an option, as this could damage the coils.
• The technician should ensure defrosted coils are make clean and in good condition. Coils tin can be gently scrubbed with a soft-bristled brush. Manufacturer'due south directions generally specify how coils should exist cleaned in club to prevent damage, especially to the fins. The fins provide extra surface surface area for rut transfer.
• If the heat transfer fins are bent, they can be straightened with a specialized tool called a fin comb. Such tasks are definitely best left to your HVAC professional.

After the technician has completed these steps and the ice has melted, plow the air conditioner on, and the system should be functioning properly in one case again. Your HVAC pro will be able to provide advice regarding ways y'all can help to forestall your evaporator coils from freezing again.
