This review is based solely on the initial contact, consultation, and estimate, as I did not have…read morethe work completed by Jazz. My initial contact with the company was excellent. The person who answered the phone was professional, patient, and courteous, even as I worked through my concerns and asked some repetitive questions. At no point did I detect any frustration or impatience, which I truly appreciated. Jazz was also able to schedule an appointment for the following day. Joe was assigned to provide my estimate. He arrived on time and had a great attitude from the start. He was patient and willing to listen to all of my concerns, answer my questions, and discuss different alternatives. Before leaving, he provided a detailed quote with different payment options, which made it easy to understand the choices available to me. I requested the consultation because I was experiencing water hammering when using multiple fixtures. Since diagnosing water hammering can involve a process of elimination to determine the underlying cause, I received different opinions and recommendations from the plumbers I consulted. Jazz recommended installing a new water hammer arrestor along with a washing machine box. One thing I especially appreciated about Joe's explanation was Jazz's no-frustration guarantee. As it was explained to me, if additional issues arose during the repair process, Jazz would address them at no additional cost. My primary hesitation with moving forward was that installing the new washing machine box could require cutting into the wall. I was advised that Jazz would replace the drywall, but I would need to hire someone else to finish the mudding and painting. I understand that this may be standard practice in the industry, so I don't consider it a negative reflection on Jazz. It is simply an additional project that I am not interested in taking on at this time. Ultimately, each plumber who provided me with an estimate had a different opinion about what might be causing the water hammering. Given the uncertainty surrounding the exact cause, I decided to start with the simplest and least invasive solution: installing a washing machine water hammer arrestor, which was recommended by another company. Although I ultimately decided to pursue a different approach, I had a very positive experience with Jazz throughout the consultation and estimate process. I especially appreciated the excellent customer service during my initial call, the quick scheduling, Joe's professionalism and positive attitude, his willingness to listen to my concerns, and the clear options and pricing he provided.

Jazz was first responsible for fixing our broken dishwasher. The professionalism and education…read moregiven freely to me during the process really stood out. They hit another home run when Isaiah and Monty were assigned to a plumbing issue at my house. It was a hectic week to start, topped off with a backed up toilet that started to overflow. After I turned off the toilet and used a plunger and some elbow grease to fight back the overflow, I knew I needed a professional opinion. Turns out, Jazz not only fixed a huge backup of sewage, fixing the immediate issue; they did it with such professionalism that I was really impressed. Monty and Isaiah were a great team. Special shout out to their non-pushy approach. I really appreciated the speed, efficiency, professionalism and honesty that these associates demonstrated. The folks on the phone, such as Mario and Adrian/AJ, are also fantastic and really made the process easy end-to-end. Well done, Jazz. That was excellent overall value and the highest-quality service I could ever ask for.

We suffer through the weekend then I call JJ because the next Livermore heat is coming. I wanted a local place because I thought proximity would help. It did. I called at 1:30 and they had a technician assigned to arrive between 2-4. They send a text message with a picture of the technician and a link where you can track his progress in an Uber like map. Very cool. Tyler arrived and he started systematically diagnosing our system. During the diagnosis he clearly explained what was going on and how he was going to systematically look at failures. He was also very tolerant of our inquisitive cat. Long story short - our AC is back up. He walked me through the repair costs and cautioned us about the age of our AC and furnace system - not in a salesy way but very consultative. We are very happy with the entire JJ experience and would, of course, recommend them again.

Dryer Vent Cleaning Service…read more I had a great experience with Aaron - AJ Service for my dryer vent cleaning. He did a very thorough job! He cleaned the external dryer vent, the inner dryer filter slot, and the entire vent system from the inside out.

Recommended him to family after our experience and they were equally pleased with their experience.

My husband and I evaluated three vendors around the area in great detail and despite Chill coming out slightly more expensive than others, we felt they were the most thorough and comprehensive during the consultation (and the many follow-up questions I had). They were also able to squeeze us into their busy schedule so we could get AC before the heat wave! During installation, they ran into several challenges with placement of the new unit and some wiring that needed more attention. They worked through and around them to make everything work out in the end. I really appreciate their flexibility and expertise to navigate all the roadblocks without changing the scope of work. TIP: Measure the space where the unit is going to be placed and make sure the new unit will fit OR that you discuss this before the project starts.

Chill is a classic example of the type of business you should avoid. A repair guy (named Vik) came…read moreby to look at my AC system. He said the problem was the starter and said he could fix it for $460. While he was fixing it, I looked up the price of the part. It was $25. He was here for only 15 minutes. After the repairs, I asked him how much of the $460 was for parts and how much was for labor. He said about 50% for each. I then let him know that I found the part for $25. He responded that he doesn't buy the parts himself. So I paid $25 for parts and $435 for 15 minutes of work. Yes, I wish I had gone with another company.

The quoted price for a two-head unit with external pump was in line or lower than the competing bids, backed by an extended multi-year warranty as Mitsubishi Diamond Certified installers. Heat pumps installed alongside existing central air is not an uncommon request, but we had a great conversation with Brook on how we might update to a more modern system in the future, given our original(!) furnace's age. Side questions for him aside, we had a thoughtfully sized system outlined and quoted within a day, and scheduled within two weeks. Our experience with the installation was similarly great, with the team arriving promptly as scheduled and taking the care to put on shoe coverings moving through the house. Everyone was polite and efficient, bringing the plan to life and bringing us in early when there were onsite decisions to be made in our unique spaces. When an issue arose on the cooling not blowing as cold as we had expected, they were quick to assist with troubleshooting, and had it fully remediating within the week. Permits are still pending due to the Oakland backlog, but their lead electrician will also be onsite during the inspection process so I have no worries there. While our immediate need during the heat wave this Spring was cooling our living spaces, I have full confidence that whenever we go to multizone heating and cooling, Spot Free will be our go-to experts!

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.

Beyond what they needed to do, Lex walked through things that would be checked by the inspectors even on work they didn't do (GFCI plugs close to where the old unit was), and walked me through why they did some of the things they did because I was curious. We're 3 days in so far, but the installation experience was great, and the daikin system is cooling the house great (and I can already see from the energy monitoring systems we have, it's so much more efficient!).
