Performed single system cooling maintenance. I checked amps, capacitor, filter, electrical, drains, air quality, safeties, temperature differential, and refrigerant temperature. The system is performing well and inside of manufacture specifications. I provided some options to better the air quality in the home and for our branded drain cleaner. I presented the air scrubber book, spoke to them about the benefits of upgrading the filter, and spoke about the versatility of our drain cleaner. I offer a bundle cost to include our drain cleaner and price if purchased separately.
