An AC tune-up service is a preventative maintenance procedure designed to ensure the efficient and optimal functioning of an air conditioning system. During a tune-up, a qualified technician inspects and cleans various components of the AC unit to enhance its performance and longevity. 

This typically involves tasks such as checking refrigerant levels, cleaning or replacing air filters, lubricating moving parts, inspecting electrical connections, testing thermostat functionality, and assessing overall system efficiency.

By identifying and addressing any potential issues early on, an AC tune-up can help prevent costly repairs, improve energy efficiency, enhance indoor air quality, and extend the lifespan of the cooling system. It’s often recommended to schedule AC tune-ups annually, preferably before the start of the cooling season, to ensure peak performance when you need it most.
