Came out to educate customer on ERV and give quote to clean it. Customer approved cleaning. Removed heat exchanger and washable filters, rinsed thoroughly. Vacuumed out cabinet. ERV has a condensate pump for drainage with an emergency pan and float switch. Float switch wired properly but condensate pump safety switch not wired in at all. Recommend adding wet switch for TE Standard Flood Protection. Customer declined for now, still wired in condensate pump float switch as a courtesy. Verified operational after. Drains into plumbing stack in attic. Also spoke to customer about our Home Care plan and recommended signing up for priority dispatch, discounts on all our services, and 3 included visits. Customer will hold off for now says they are satisfied with current HVAC service providers. Left brochure and still recommended our plumbing and electrical services for consideration.
