Completed one system tune up found early signs of mold in crawlspace. Needs UV inhibitor to clean air and kill any bacteria allergens and viruses in air that could cause harm to residents. Blower is clean filter is good. Pump is working. Outdoor unit has good pressures and working electrical components no signs of degradation on connections. System would benefit from compressor saver to take load off of compressor and allow it to live longer as well as a surge protector to protect any electrical components from failing during a power surge.
