For this job, he was performing routine maintenance on a AC and condenser as well as the furnace. Everything with the furnace is checking out well I changed the filter to Merv 5. It originally had a filter, Merv seven. That is a good filter however, if nobody has allergies in the house, I would use the Merv five because it lets in more airflow. After checking the condensing unit, refrigeration levels were a little bit off, but that’s because it was so dirty. We ended up doing an advanced coil clean and I showed the daughter before and after photos. After cleaning it off, refrigerant levels were in the green and the system is running very well at this time thank you for choosing LBA! - Walker
