Tune up Suwannee. Did a leak search on both evaporator coils. Did not find any leaks. Upstairs systems capacitor was weak. I changed the capacitor. Main level units capacitor is within range. Both blower wheels are clean. Filters are clean. Drain lines are clear. No cracks in either heat exchanger. Pressures on both systems are within range. One of the outdoor capacitors was weak. I changed that capacitor. The other capacitor was within range. Both systems are cooling at this time.
