    I've had Mike come out to do two different jobs in the last year or so. He does excellent work and is super friendly and priced fairly.

    I am still in the research process for this project, but I can say how impressed I am with Water…read moreHeaters Masters. They responded to my request so fast I thought it was a bot, but it wasn't. A real person called and left a message. I called back to explain what I was interested in and he scheduled an appointment for that day (I think). I was assured that I'd be called or texted when the technician was on his way. I expected to have to wait the full 2-hour window I was given, but no! I was called about 5 minutes before the window started to see if I was still available. The technician arrived exactly on time, right at the start of the window! After a short explanation of my needs he just said "OK, let's take a look at the space and talk about it." He explained every step of what they'd do to install a tankless water heater, he looked at the whole area to check for pipes, electrical access, spacing inside and out for a condensation line - making feel very comfortable that it would be planned before the installation to avoid last minute issues. A big plus, he told me he'd be part of the installation team. He also told me I should go ahead and get another few quotes. I think these guys are confident they're giving the prices in the sweet spot of costs. Then we spent time just talking about landscaping and plants! I'm not in a hurry to start this project, it's on my list of improvements and I'm just starting to investigate. However, I'm extremely impressed with the service given at this stage, the thorough approach in explaining, and the honestly. I will get another quote, but the next one has a high bar to cross; not only the service, but Water Heaters Masters quote was WELL below the only other quote I had gotten so far. I have a very good feeling about WHM. I'll come back to let you know more when I've finished the whole project.

    After getting a very high quote from a major plumbing chain, we decided to contact Water Heater…read moreMasters. We had an absolutely fantastic experience with Water Heater Masters. Alex sent our technician, Rojo, who helped install a new 40-gallon gas water heater in our indoor utility closet, and he was incredibly diligent, professional, and efficient from start to finish. Installing a tank in an inside closet can be tricky, but Rojo handled the entire job seamlessly in just 2 hours. He replaced everything with high-quality components, including: * New hot and cold water flex lines * A brand new water shut-off valve * A new gas flex line and sediment trap * Fully reworked earthquake straps (to meet California safety codes) * Properly updated T&P line and venting He also took care of the removal and disposal of our heavy 18 yr old tank, leaving the utility closet completely clean. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call Water Heater Masters and ask for Rojo. Highly recommended!

    There are a lot of plumbers out there to choose from, and this is only my opinion. But Taz plumbing…read moreis the best. Taz was one of several recommended plumbers on Yelp, and I had used him once before when we had a pipe burst. He came out super quick and fixed the problem and did gouge me on price. So when I had this big project (add water and sewage line to an ADU) I was happy to see that Taz came up as an option. Taz plumbing came out evaluated the work and when it came to price he was less than the competition. He is super easy to communicate with, there are no frills. The work was done in a timely manner. Taz had to pivot twice on this project because of the piss poor San Leandro inspector, but Taz made it work and didn't overprice the extra work that was needed. Taz plumbing in my opinion is the GOAT of local plumbers and I would call him again!

    From start to finish, working with Gee at Taz Plumbing went very well. I reached out via yelp…read moreinitially, response came quickly and we reviewed what was needed. I knew the Pressure Regulator Valve needed to be changed and the shower stems needed to be replaced. I had 3 other estimates completed for the same job. They range from repiping the entire house, piping from the street, changing the water heater, tearing down walls, etc. Taz Plumbing was the ONLY company that did not try to sell me additional work. There was no up sale after the initial estimate either. The work that was discussed was the work that was carried out. Estimate and total cost were still lower than the other quotes. And some of those quotes did not even include the proper work to satisfy the need. 1 year warranty on the work included. The cost of experience was well worth the price paid for the time spent on the job. I 100% recommend working with Gee and Taz Plumbing.

    Interviewed 5 companies for our project, super glad we went with Spot Free. We have a single story,…read moreabout 2600sqft home, with floor vents for forced heating. The gas furnace was about 25 years old and rated for a 1000 sqft home and the ductwork under the house was ripped and torn. Our house wasn't heating, our gas bill was $400 a month alone. Instead of trying to fix the current system, we wanted to upgrade to AC/heat and modernize with ceiling vents. We landed on a hybrid system: 4 ton variable heat pump outside, a backup gas furnace in the attic, whole house filter, 2 zones for the house because of our layout with two gen 4 nest thermostats, r8 ductwork, 15 ceiling vents, 2 air intakes, and all the permits. Their quote included a 3 year warranty on labor, whereas the other 4 companies were only 1 year. Nice bonus perk. The project took 5 full days to complete, and they are coming back Monday for a partial day for final touch ups. Anson came by same day and walked through the property with me, getting the full picture of what we would need. He literally drew everything out, saying it's very important that I understand what is going on because it is permanent. Anson cleared up a ton of questions I had. We talked over vent location, system size, zoning, equipment, everything. He took his time and was very patient. The quote he gave was very competitive to the other 4 I received. I decided on Spot Free because of Anson's care in explanations, his patience and detail, their quality of yelp reviews, the labor warranty and finally their price. I kept the contract though because of Jamie lol she is such a sweetheart. One of the other companies, bigger named and 2k+ reviews offered to price match, but I loved Jamie so much, as well as Anson was so quick to answer my questions over text, and the labor warranty was better. Decided to stay with them even with the price match, although that was very generous of the other company to do. The install itself went super smoothly. Brandon was the lead communicator with us on the project. He, and the whole team, did an amazing job! I felt like he kept us in the loop about everything important, in a non-invasive way, we got the vents mostly where we wanted them (beams/structure dependent), and we could still live in the house mostly uninterrupted with what I felt was still a ton of privacy given the scope and nature of the work. Honestly didn't even notice they were here for the most part, my husband and dad napped through most of the noise lol! The amount of care the team had for our belongings was also very impressive, and noted. They covered everything with plastic sheets, including stuff in our garage like our stroller. That attention to detail was super kind! They also fully cleaned up after themselves every day! Vacuumed, swept, taped up the work in progress vents, removed sheeting, etc. They were also all super careful to keep doors closed, we have 2 cats and I never worried they would be let out. It was a pleasure having the team here! The vents look super clean! Very well done. The thermostats work great, Brandon helped get them set up on our phones in the google home app and patiently, after what I know to be a long day, taught us the various settings so we could get started and ensured all parts of the system were working, much appreciated! We have heat! This is excellent! And the system is so so so quiet! It's just night one after install, but the whole house is an even temperature. Looking forward to playing with the app and sensors to fine tune our comfort here, but it's so easy and it just works so far! I'm super excited for summer, to test the AC out. I'm also looking forward to our next PGE bill, to see if maybe we are saving money lol! Spot Free HVAC is 10/10, wonderful company and people!

    Very easy to communicate with and book a quote. I received 3 quotes for our HVAC work:…read more- Spot Free: $21K - Vendor we used: $23K - Another vendor who we used before and were happy with but increased their pricing recently: $32K We decided not to go with Spot Free for 2 reasons. First, the heat pump brand was changed in the quote to one that we did not want (Carrier). We were replacing it due to leakage of carbon monoxide. This is obviously a safety concern for us, but also a peace of mind issue. We had discussed using Carrier at the site visit, but I was adamant to avoid it. Second, Brook mentioned that there was a manufacturer's recall on our existing 1-year old Mitsubishi heat pump (we have 2 zones with 2 separate units) and that we should pay him out of pocket to fix it. I was confused, because we received no information regarding a recall and typical costs associated with a recall are not paid by the customer. Furthermore, we hadn't experienced any issues and we're still within the warranty period from the manufacturer and installer. Brook said he had been processing a lot of recalls on units he installed and Mitsubishi was slow to send parts so it's easier to pay him directly for the repair. I contacted the original installer, who we had a very positive experience with initially, and they said there was no recall. I also looked online and couldn't find any information regarding a recall.
