"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."

"Proffesional installation by Hector and Michael. They installed Bradford White Water Heater, and day before installation I called and asked Hector if they can install also Halo 5 water treatment system, self cleaning, and he said Yes! Clean, speedy job. Great price. Effective, fast communication. Hector answered my questions via phone, text, email literally within minutes, or instantly. Highly recommend this crew, company. Already informed my family, if they need fast, reliable service, installation of new systems, to contact them. GO SPEEDY WATER HEATERS!!!! Thank You for great service, consultation, explanations, answering all my questionsin details, fast, and installation for great price. I would give them 6 Stars, if I could."

"I was WOWED by every aspect of our project. I called on Sunday, expecting to just leave a message but got a human voice. Angie was so helpful in answering my questions. She scheduled weds. for replacement of my water heater but because of a cancellation she got them to come on Monday. Both Juan and William Came in and went to work. Got the job done in a couple hours . I didn't have to deal with the old water heater. I was very happy with their work and they were very patient with my questions. George also came early to flush my tankless. This is a well run company and their prices are fair. I will be contacting them for any other jobs I have. Thank you!"

"Excellent job! Good Guy Plumbing fixed my leaking water heater quickly and thoroughly for a fair price. Spoke with Robert over the phone and David came out to do the repair. Both were professional, knowledgeable and kind. I recently bought a new townhome and will be doing business with them for any future plumbing needs. Many thanks to David, Robert and Good Guy Plumbing. It’s such a relief knowing there are good, honest plumbers I can count on."

"The team of this company which included Samuel, Agapito and Sergio did a wonderful job. The job was really hard. It included removing an old water heater from a small cabinet under the stairs and placing a new heater which was taller. I am very grateful for their job."

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."
