Rancho Cucamonga, CA - (10-12 REQ) COD. Spoke with Zack. He recently purchased this property and would like to get an estimate for an automatic shut off valve required by his insurance. He was also told that the water pressure is way too high and would like it diagnosed. There's also an issue they're having with the washer valve leaking, but they think it might be just due to the high water pressure issue. They currently have the water to the laundry shut off to prevent leaks. Please get approval on any pricing BEFORE performing any work!

They continue to take good care of my 35 year old HVAC system, replacing some of the electronics in the blower that I'm pleasantly surprised they could still find. The tech was excellent at explaining what failed, how he was going to fix it and how much it would cost.

8 - 10. Spoke to Judy. Osmosis water filter under the sink needs to be replaced, she said the water is starting to smell like mildew. Chris (tech) called in the order because he has been out there before and remembered which filter she needed (she said it was a special one), he called in an order to Thompsons. it is under JUDY NELSEN. She would also like to order an extra to keep on hand for next time. Chris said there was only one in stock, but when you go to pick it up, please ask them or see if you can order another one for her.

James was here on Tuesday. He got the screaming toilet to stop. But it has returned and someone will be out today, Thursday. I just don't think I should be charged another service fee $124.00 since the issue was not fixed.

He should've called me before clearing out the line as I have always had the line jetted out as he recommended on the receipt after the job was done. As the owner, I pay for the work he should have called me prior to the work and I would have told him to jet it out.
