"I had a situation that wasn’t an emergency but left me with my water cut off—Red’s (Cody) was extremely responsive and came to my aid very quickly and efficiently—reasonable rates and just a flat-out congenial guy that could be trusted—appreciate him and have saved his contact information if I ever need him again—many thank to my fellow Bearcat!!"

"We had another plumbing company come out due to a leak. Rather than do any diagnostics, they just replaced the pressure valve. It still leaked. I called the next Monday and was told oh, you need a new water heater. Johnny Gavilan from Preferred Home Services checked a couple things and found our expansion tank was bad. He did warn us there still could be a problem with the water heater but at least he checked first. If we need the water heater replaced, our expansion tank will be new!"

"There was water leaking from my intake valve  on my hot water heater.      I called and made an appointment, but it wouldn't be for 2days.     When I told him  that I didn't have any hot water - he then told me that   he would    to come after he was done for the day . By 6:30  he was here.  Changed the valve  and made sure all was good and was gone within 30mins.     Great  service!  He was VERY knowledgeable and nice.   VERY HAPPY!!!
