• Tune-up catches two weak capacitors on three furnaces, off East Camperdown Way, Greenville, SC. We went through heating maintenance on all three furnaces at this property: main house, upstairs, and guest house. Checked inducer motors, capacitors, igniters, flame sensors, and blower motors on each system. On the main house furnace, the inducer motor's capacitor was weak and leaking oil, so we replaced it. In the guest house, the blower motor's capacitor had also gone weak and got replaced. The upstairs furnace just needed a gas pressure adjustment to bring it to spec. All three systems are heating properly now. We also flagged some air leakage at the main house supply plenum for a separate repair quote.
• Replaced crushed return duct, fixed airflow problem, off Elmwood Avenue, Greenville, SC. The return duct feeding this 3 ton system was crushed down to a 16 inch line, choking off airflow and causing the system to freeze up. We pulled it out and installed a new 18 inch R-8 insulated return, sized correctly for the unit, and sealed it in with mastic. We also replaced a 10 inch duct connecting the two return boxes with a custom sheet metal transition built to match the box openings, so the second return can pull its full share of air. After install we re-tested static pressure and checked airflow and temperature split to confirm the system was running the way it should.
• Cleaned condenser coil, plugged mis-routed secondary drain, off Westchester Road, Greenville, SC. During a tune-up, the condenser coil was found dirty and got cleaned so the system could move air properly again. We also noticed the secondary drain on the evaporator coil had never been plugged off correctly, which let water run out underneath the house. That drain is now sealed to stop the leakage. While testing, the condenser fan capacitor came back weak. The system is running fine for now, but that capacitor is worth replacing before it fails outright.
• Fixed a mis-plumbed secondary drain line, off Meyers Court, Greenville, SC. Found the secondary drain on the main pan wasn't installed right and hadn't been plugged, so water was dripping out where it shouldn't. On top of that, the secondary pan under the unit wasn't capped, which let water in that pan run straight onto the ceiling below. We corrected the drain setup and capped the pan so water goes where it's supposed to instead of into the ceiling.
• Topped off refrigerant on an aging R-22 system, off Verdun Avenue, Greenville, SC. This Goodman system was low on charge and not cooling like it should. We hooked up gauges and found the pressures well below where they needed to be. Added a pound of R-22 and the system came back up to proper operation, cooling normally again. That said, this unit has a refrigerant leak somewhere in the system, so this fix is a temporary one. R-22 is an older refrigerant that's being phased out, and repeated topping off isn't a long-term solution. System replacement recommended
• Replaced a failed capacitor to restore cooling, off Mary Street, Greenville, SC. This system had stopped cooling, and a check of the outdoor unit found the problem: a failed 35/5 µF capacitor. That part is what gets the compressor and fan motor started, so once it fails the system can't run. We swapped in a new capacitor, then checked the compressor and fan motor amp draws against their rated loads, inspected the contactor, and checked the refrigerant pressures. Everything came back within spec. Cooling was restored and the system was left running properly.
