Ac service in Alpharetta. Discovered upstairs system with extremely clogged filter causing system to struggle and at the same time trying to compensate for main level system not working properly. Discovered main level system leaking refrigerant from indoor coil. Due to age, replacement of the ac portion on the system is recommended at minimum. Homeowner has chosen to replace Main level AC AND COIL 16 SEER. Collected deposit of $460. Charged system for temporary cooling. Need to schedule install.
