How often should a home’s HVAC system be serviced for optimal performance?

The recommendation for servicing a home's HVAC system at least once a year is based on the need for regular maintenance to ensure optimal performance, reliability, and efficiency. Annual servicing allows a qualified technician to inspect, clean, and tune the system, which can help prevent potential issues that could lead to costly repairs or system failures.

Regular maintenance includes checking refrigerant levels, inspecting electrical components, cleaning or replacing filters, and ensuring that the system operates efficiently. This proactive approach not only extends the lifespan of the HVAC system but also improves indoor air quality, which is crucial for the health and comfort of occupants.

While some may consider more frequent maintenance, such as every six months or monthly, it is generally found that an annual service is sufficient for residential systems, unless specific circumstances warrant more frequent checks, such as heavy usage or environmental factors. Long intervals, like every two years, may lead to neglecting necessary upkeep, resulting in decreased efficiency and potentially voiding warranties.
