Maximizing Efficiency: How To Maintain Your HVAC System

Posted on: 6 July 2023


Your HVAC system works tirelessly to keep your indoor climate comfortable all year round. But like any other machine, it requires regular care and maintenance to function efficiently.

This article walks you through practical steps to keep your HVAC unit running smoothly and efficiently.

Change the Air Filters Regularly 

Changing the air filters in your HVAC unit is one of the simplest yet most effective maintenance tasks you can perform.

Air filters work to trap and hold various airborne particles that can harm your system's components, including dust, pollen, and pet dander. Over time, these filters can become clogged, causing your HVAC system to work harder to circulate air. This decreases efficiency and can lead to higher energy consumption and increased wear and tear on the system.

In fact, one of the leading causes of HVAC system failure is a dirty filter. When a filter is clogged, it restricts airflow through the system, which can cause the heat exchanger to overheat and shut off too quickly. In cooling mode, inadequate airflow could cause the evaporator coil to freeze up, potentially leading to costly repairs or even system replacement.

You should change your air filters every couple of months, depending on usage and the type of filter used. However, if you have pets or live in a particularly dusty area, you might need to change them more frequently.

Regularly replacing your air filters can ensure better airflow, improve indoor air quality, extend the lifespan of your HVAC unit, and save on energy costs.

Inspect the Electrical Components of Your HVAC

Over time, wires can become loose or frayed, connections can weaken, and components can wear out, all of which can lead to system inefficiencies or even breakdowns. Regular inspection of these components can help you identify and address potential issues before they escalate into major problems.

For example, the contactor in your HVAC unit, which controls the electrical flow to different components, can wear out over time. A worn-out contactor can prevent the start-up or operation of your system, leading to a complete breakdown. Regular inspection can help identify signs of wear and tear early, allowing for timely replacement and avoiding unexpected system failure.

Similarly, capacitors, which help motors in your system start and run, can fail over time. A failing capacitor can lead to problems like reduced cooling capacity and increased energy consumption.

Dealing with electrical components carries inherent risks, including potential electric shock. Therefore, such inspections should ideally be performed by a trained professional.

Regular professional maintenance, typically recommended twice a year, can ensure that all electrical components of your HVAC system are in good working order, ensuring efficient operation and prolonging the lifespan of your unit.
