Regular maintenance of the HVAC system keeps it running as efficiently as possible and saves you a lot of money by preventing costly repairs.

For the HVAC system to function effectively, it is important to inspect and maintain the filters, fins, and coils regularly. This ensures that the system runs efficiently and effectively. Neglecting HVAC system maintenance will lead to a decline in system performance over time and an increase in energy consumption.

Air Conditioner Filters

We have devoted many posts to emphasize the importance of changing the air filters regularly. Dirty and clogged air filters obstruct airflow and reduce the system’s efficiency. If the filters are clogged with dirt, the air that passes it will carry dirt to the evaporator coil and reduce its heat absorption capacity. By regularly replacing the air filters homeowners can reduce energy consumption by over 10 percent.

There are different types of air filters available in the market, and some of them are reusable and others need to be replaced. During the winter season, it is recommended that the air filters are replaced every two months or so. Depending on how much the system is used, the quality of air, and whether or not there are pets in the house, one may have to replace the air filters at shorter intervals.

Air Conditioner Coils

The air conditioning system’s condenser and evaporator coil collect dirt over the years. Although clean filters ensure that the coil does not get dirty too quickly, but it will still accumulate some amount of dirt eventually. This insulates the coil and reduces airflow. For this reason, it is important to inspect and clean the coils every year. If the outdoor environment is dusty or there are a lot of trees around the house, the outdoor condenser coils will also become dirty. It is important to keep the surrounding environment clean of any sources of pollution.

Condensation Drains and Coil Fins

Clogged drains may prevent the air conditioning unit from reducing the humidity and may result in excessive moisture. This can cause damage to the property and may impact the health of occupants. St. Louis HVAC experts recommend that homeowners should pass a stiff wire through the drain channels to clear any blockages. The fins on the condenser and evaporator coils can get bent and will block airflow across the coil. If your air conditioning unit is having the same problem, you can try using a tool called a fin comb to bring back the fins to their original shape.

Preparing For Winter

During the winter season, when you no longer need the air conditioner, it is best to cover it or remove and store it. This will protect it from the elements and debris. Call Scott-Lee Heating Company at (314) 200-0788 for this winter’s HVAC maintenance.
