Dirty Evaporator Coil Symptoms and Maintenance
Regular maintenance of central air-conditioning systems San Antonio is a vital part of home ownership. Air-conditioning systems San Antonio contain many components that have to work in tandem to provide proper cooling and heating and must have regular maintenance during the year. There are a few major components that regular maintenance should be done on because if maintenance is not done a central air-conditioning systems energy efficiency and regular operation can become altered due to lack of maintenance resulting in lower energy efficiency and discomfort. One of these components is called the evaporator coil. An evaporator coil is responsible for absorbing heat from the returning air resulting in a temperature drop in the supply air. There are many symptoms that may occur when the evaporator coil has not been properly maintenanced. Some examples of symptoms can include decreased airflow, decreased evaporator coil temperature difference, and evaporator coil freeze ups are a few issues that may result from a neglected or malfunctioning evaporator coil.
Decreased Airflow
During normal air-conditioning operation air recycles back to the air handler where the air is filtered and then passes over the evaporator coil to be reconditioned or cooled then continues to be distributed throughout the home via supply ducts. During this air reconditioning process as said before, returning air must pass through the evaporator coil and filter. If a homeowner has neglected their filter air may not be able to pass through properly resulting in decreased airflow across the evaporator coil which can result in the blower motor overworking itself and the evaporator coil unable to maintain a proper temperature. Another issue that can arise preventing airflow from reaching the home can be a dirty evaporator coil. If an evaporator coil accumulates too much debris the air may not be able to pass through the coil at the proper CFM and be reconditioned resulting in discomfort and evaporator coil freeze ups.
Decreased Evaporator Coil Efficiency
An evaporator coils normal operation will decrease reconditioned air temperature. For example, a homeowner sets the thermostat to 74° degrees , but the indoor air temperature is 85° degrees. In this example, the homeowner wants to bring down the temperature 10°degrees in the home, so the air-conditioning process begins by cooling 85° degree air. This 85°degree air will pass over the evaporator coil where a refrigerant absorbs latent heat from that 85°degree air dropping its temperature and then distributing that cooled air into the conditioned space of the home. This process will continue until the air is reconditioned and the temperature of the air is dropped to meet the 74°degree setpoint placed by the homeowner at the thermostat. When an evaporator coil is malfunctioning or is dirty the evaporator coil will have problems absorbing excess heat from the reconditioned air resulting in less heat absorption and longer air-conditioning system run times which lower the home's energy efficiency San Antonio.
Evaporator Coil Maintenance
Evaporator coil maintenance should be done by a trained HVAC professional San Antonio. Property evaporator coil cleaning and maintenance is very important when temperatures in the summer exceed 90° or greater. The homeowner can do preventative maintenance that will help the evaporator coil and blower assembly to stay cleaner and more efficient by regularly changing the air-conditioning systems filter. In addition, the homeowner should try to invest in the best air filter possible. We here at AAA Duct Cleaning, LLC recommend pleaded filters with at least a Merv rating of 6 for proper filtration of debris and allergins.
