I am a highly skilled and experienced home service professional. I recently completed a job that involved changing filters, cleaning coils, and checking the operation of a sequence. The first step was to access the air handler unit and remove the access panel. I then removed the old filters and replaced them with new ones. Next, I cleaned the coils using a coil cleaner and a brush. Finally, I checked the operation of the sequence to ensure that it was working properly. Overall, the job was completed quickly and efficiently, and the customer was very satisfied with the results.
