Need Split AC Maintenance Expert

I’m scheduling routine maintenance for my split-type air-conditioner and want someone who knows the system inside out. The service visit should cover the essentials that keep the unit running efficiently and extend its lifespan.

Please make sure the following tasks are completed during your visit:
• Filter cleaning or, if necessary, replacement
• Accurate check and top-up of refrigerant levels
• Full system inspection, including electrical components, coils, drain line, and overall performance test

I expect you to arrive with the tools and basic consumables needed for a standard split AC tune-up, document any additional parts that might be required, and leave the workspace clean when you’re done. If you find anything outside normal wear and tear, let me know right away so we can decide on next steps.

Kindly let me know your earliest availability and how long the service typically takes for a single indoor/outdoor unit pair.
