On arrival we diagnosed the downstairs condenser and discovered that the fan motor and compressor weren’t in operation. On further inspection we found that the capacitor to the condenser had ruptured causing the system to not start. We replaced the capacitor and were able to have the system engage. We offered the homeowner to install hard start kits on both systems, which he agreed to and proceeded to check charge. We found the downstairs system’s refrigerant levels below specs so we topped of the system. The downstairs a/c system is now functioning properly at this time.
