All wiring is tight and in good condition. We spoke about the filtration on the system. The filter they are using is a good filter for the system. I prepared some options for the system, one of which is a uvphotomax that we spoke about. The refrigerant pressures are in correct range per manufacturer specifications. I completed our check sheet and emailed it to the customer. The system is working properly at this time. The customer had a work meeting come up that he needs to attend. I emailed the quotes to the customer for review.
