"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Every aspect of the work was excellent. Arrived on time, professional, friendly, covered the floors, and very responsive.


**NOTE: Water heater broke a few days ago (as of 6/8/2015). They came out and replaced the water heater. It was not their fault the water heater broke but they provided great service and were very responsive once again."

"Marcell and True Blue Plumbing were a pleasure to work with. He was friendly and took pride in his work and client satisfaction. Marcell installed a gas line for me in Napa within the same week of providing the estimate, and he even helped me flush out my water heater free of charge. I will definitely use him for any future plumbing needs. My profession is a property manager and itâ s hard to find quality vendors like True Blueâ ¦Thanks again."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"I would highly recommend Ray’s Rescue Plumbing. He was very clean, prompt, courteous and knowledgeable. We had several issues ranging from leaks, repairs and installing a tankless water heater. Ray’s prices were competitive and he actually saved us a few thousand dollars from a previous bid from a ‘not so honest’ plumber."

"Green Core HVAC was awesome to work with! The team did a great job helping us pick the perfect AC unit for our home. They showed up on time, got the new AC installed quickly, and left the place spotless. Our house is cooler and more comfortable than it’s ever been. You can tell these guys really care about doing a great job. I’d 100% recommend Green Core to anyone needing AC work. Super professional, super friendly, and they really know what they’re doing!"

"I have to give this 3 star rating based on price. 5 stars for customer service, promptness, courtesy and professionalism. The gentleman that provided me with the estimate was top notch. NO pressure, 100% honest and generally very respectful of my interaction. However, the price quoted is, without a doubt, not realistic. I searched online for furnace pricing and a very high quality and highly rated piece of equipment averaged around $2500. But my quote for a new furnace with installation was $7500! This is totally unacceptable! Furnace replacement is not rocket science. As a very handy guy, and one who has, first hand, witnessed an installation, $5000 in labor for a 4 to 5 hour job is just way more than this is worth. $1000 per hour is more than lawyers and doctors charge. And there is no flexibility on this pricing. And I don't feel that the months overhead of this company should be charged on each and every installation. Additionally, I received quotes from 3 other companies and their pricing is almost identical. Price fixing? Taking advantage of consumers? You make the call. BUYER BEWARE!"
