Condenser coils transfer heat between two mediums in heating and cooling systems, such as air conditioning units. They are self-contained but may require replacement over time. It’s important to hire a professional to replace the coil and dispose of the old unit properly. A sign of a problem is when cooled air is hotter than the thermostat setting.
A condenser coil is one of many types of heat exchangers. The main purpose of a heat exchanger is to efficiently transfer heat between two mediums. Condenser coils are found in space heaters, air conditioners and car radiators. While there are slight differences in the function of these devices, the main purpose is the same.
The term condensing coil can be used to describe all heating and cooling systems or to refer specifically to air coils. Air coils are a subset of heat exchangers and are found in air conditioning units, both in cars and buildings. The condenser coil itself is snake shaped, with a complex set of internal tubes used to manage the process of transferring the heat or cooled air.
In a heating, ventilation and air conditioning (HVAC) system, water, steam or a chemical refrigerant is used. The liquid is cooled by the cooler, then circulated through the system. The condensing coil is where the liquid mixture changes from liquid to gas. This compressed and cooled gas is then pushed through the ventilation system.
In the vapor compression and refrigeration cycle, the condenser coil is the evaporator. This process is repeated to continuously supply fresh air to the building. It is important to note that most condensing units are self contained. However, over time, the unit may fail, causing a reduction in efficiency that may require complete replacement over time.
A variety of condenser coils are available, depending on system specifications and overall output volume. It is very important to replace the condenser coil with the corresponding unit to avoid damage to the air conditioning unit. Keep in mind that it’s best to hire a professional HVAC mechanic to replace the coil on your unit. This is often necessary to maintain the warranty and avoid damage to the very expensive unit.
The first sign that there may be a problem with the condenser coil is when the cooled air temperature is hotter than the thermostat setting. Check the amount of refrigerant available in the system to make sure there is enough refrigerant. If the coolant level is fine, but the air isn’t fresh enough, think about replacing the condenser coil. In many areas, there are restrictions on the disposal of old capacitor batteries. Take the time to review local guidelines to ensure the old unit is taken to the appropriate disposal facility.
