Upon arrival customer stated that she didn't know if the AC was having any problems she just wanted to check it out and make sure it was working properly Checked out system thoroughly and found no problems and system had an almost 20 degree delta after switching it to cooling Spoke to customer and let them know they need a new filter due to it being heavily caked and customer said we normally order her filters Customer also wanted to go ahead and get a compressor saver installed to lower the inrush amps on the compressor Returned for rec work and got new Aprilaire upgrade kits installed
