Best AC Replacement in San Francisco CA

We tried to DIY and fix a water temperature issue with the shower and replaced a thermostatic mixing valve. While we fixed that part, we created a different problem and started having issues with our hot water pressure. We couldn't figure out how to fix it so called Ace because a low pressure shower is just way too depressing to start a day.

Called for an appointment in the morning and got an appointment the same day in the afternoon! Bonus two was that the service technician, Derrick, showed up on time, and was professional, friendly and knowledgeable. He diagnosed our issue, which was not anything to do with an air block as we had concluded from too much YouTube sleuthing (yes, best to leave these things to the actual professionals), and restored our hot water pressure. Yeah! I'd definitely call and use Ace again for any future plumbing needs.

If I could give a zero I would. This place is nothing but a ripoff. We had to use them since this is the only place our home warranty allowed. Since March we had been dealing with the screen not working on our water heater. After around 12 visits, over $7,000 in costs for a new water heater and prior visits, they now left us with a water heater that is tripping the outlet GFCI about every 4 hours! When I called for their assistance to help, they wipes there hands clean and said I can either call an electrician or another plumber, but they are done with services for me. So 9 months later we are in worse shape than when we started. They don’t back their work, go somewhere else!
