    Our technician arrived on time, gave us an estimate of the repairs and completed the repairs within an hour and our dryer is working again.

    Chill Heating and Cooling

    Our hvac decided to give out right before another heat wave, and a year after our warranty…read moreexpired... of course. 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.

    Spot Free HVAC Air Services - Carrier Heat Pump 37MURA install in Castro Valley Ca

    Spot Free HVAC was our top choice, from their great reviews, detailed evaluation, and helpful…read moreno-pressure suggestions. 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.
