11 - 2. NET 30. Spoke to Albert (main POC). He will not be on-site but will let them know you are coming. This is for Vedic Temple - one of the rooms the ac is not working well. Couple of problems with some of the units not working properly. Big one in the back not working well at all. He said whoever is there will let you know where the issues are/which units. Quoted him $178 for diagnostic, but if there is another unit they want looked at please let them know it will be that additional fee of $99 to diagnose more than 1 unit. They weren't really sure if it was one or multiple, they just know a few rooms are hot.
