I am a home service technician, and I recently completed a job for an unknown age/brand of unit. The unit was booked for 8/18/25, and I arrived on-site at 9:00 AM. I performed a thorough inspection of the unit, identified the issue, and provided a detailed estimate of the cost to repair it. I then ordered the necessary parts and completed the repair, ensuring that the unit was functioning properly before leaving the site.
