Condensate pump for the HVAC unit has failed, this is what’s causing the standing water inside crawl space. Homeowners already had a HVAC tech tell them it was a plumbing issue… that would be false. They need to contact a HVAC company to install a new condensate pump with a alarm system. They also need to contact a water damage company to remove the standing water inside the crawl space. Collected $59 dispatch fee for todays visit. Sent copy of todays invoice to homeowners email.
