If an AC unit is rarely used but stays on all year long, it's essential to have it serviced at least once a year. Even if the AC unit is not used frequently, it can still accumulate dust, dirt, and debris over time, which can affect its performance and efficiency.
Regular maintenance ensures that the AC unit remains in good working condition, reduces the risk of breakdowns when it's needed, and helps prolong its lifespan. Here are some key points to consider for the service schedule:
Annual Servicing: A yearly maintenance service by a qualified HVAC technician is generally sufficient for AC units that are rarely used but left on all year. This service should include cleaning the internal components, checking for refrigerant leaks, inspecting electrical connections, and ensuring the unit is operating optimally.
Seasonal Checks: If the AC unit is only used during specific seasons, consider scheduling maintenance at the beginning of each cooling season. This ensures the unit is ready to perform efficiently during its intended period of use.
Visual Inspections: In addition to professional servicing, perform occasional visual inspections yourself. Check for any signs of damage, leaks, or unusual noises coming from the unit. If you notice any issues, it's best to have them addressed promptly.
Filter Cleaning/Replacement: If the AC unit has a reusable filter, clean it regularly according to the manufacturer's instructions. If it uses disposable filters, replace them as needed, even if the unit isn't used frequently.
Protecting the Unit: If the AC unit is rarely used, consider covering it during periods of inactivity to prevent dust and debris from entering the system.
By following these guidelines and having your AC unit serviced regularly, you can ensure that it remains in good condition and performs optimally when needed, whether that's during the summer or any other time of the year. Additionally, regular maintenance can help identify and address potential issues before they escalate into more significant problems, potentially saving you from costly repairs in the future.
