He was thorough, even recording videos of his initial inspection so that we had a record. I especially appreciated that he called out Alameda regulations that were going to change in 2029 (this informed our decision to go with a heat pump now) On the day of the installation, we had an amazing experience working with Sam, Benny, Jesus, and Jorge. They were always very thoughtful and polite. Anything that might deviate from the original quote, they would give us a headsup. For example, they noticed that one of the pipes looked missing from the outlet in the yard, and that they would just charge us for parts if they needed to go out to buy a pipe and install it. Fortunately, the pipe was just hidden. They even went out of their way to help us fix one of our broken stairway steps. It was an incredibly smooth process, and we LOVE how quiet the heat pump is. (It's so quiet, we weren't sure if it was working!) My wife and I highly recommend them!

Paul, the owner from MechPros HVAC came over the weekend to do the assessment and consultation. It was very helpful be able to do it over the weekend so I didn't have to take time off from work. He was on time, communicated well, and very thorough. Among the half a dozen vendors I contacted, he was among the few that truly listened to my input instead of trying to upsell or push options I wasn't interested in. After comparing all the quotes, MechPros' quote was very competitive. I decided to go with them and scheduled the job which was able to start quickly in about a week after signing the contract. On the scheduled day, Will and Kieran, the two installation crew members, arrived right on time. They were courteous, personable, and professional, and did a good job. They kept the job site clean and neat with drop clothes with minimum disruption. After two days of work, the installation was done. They cleaned up nicely, took away all the disposable materials, and restored everything back to where things were. The installation job was done very neatly in the attic and backyard. I can tell they are proud of their work too. The new system is much better than the system it replaced. After the system started up, I noticed some issues. Paul was very responsive and sent a technician immediately to check it out. After a repair that wasn't successful, he personally came out and concluded that the issue was related to the equipment. Paul took responsibility and ownership of addressing the equipment problem under warranty with the manufacturer. He sped up the resolution by fronting the cost of providing replacement components and dealing with the warranty replacement parts separately to reduce the system down time. I appreciate MechPros HVAC and Paul for taking ownership and having customer service as a top priority. After the problem was resolved, MechPros also helped coordinate the city inspection to secure the final permit approval. I would not hesitate to recommend MechPros HVAC for anyone who needs HVAC system services.

Worth Every Penny…read more After being without A/C for three weeks, I was dreading the call. I had heard plenty of horror stories about HVAC companies, and I was hesitant when I learned there was a fee just to have a technician come out and evaluate the system. But it was absolutely worth it. Peter was fantastic--professional, thorough, and honest. He carefully checked the system, made the needed repair, and corrected a part that had been installed incorrectly. I was convinced we were looking at a $5,000 to $15,000 compressor replacement, so I was incredibly relieved when the total came to under $300. We now have cold air again, and I could not be happier with the service. I would definitely recommend them to anyone who needs an HVAC company they can trust.

The service call itself seemed high, but I had no reasonable comps and did not balk. Tech was on-site nearly 2 hours, trying to troubleshoot; I had no fault with him. Conclusion: faulty MSP breaker. "Cost sheet" price to replace: nearly $500. WTH! Called Connolly, was told that was the price; tech himself said the price included built-in labor. The part itself from nearby hardware store: under $25 including tax. I declined the install and dispatched the tech. The tech was already on-site; with experience, should have taken under 10 minutes. $500 was over-the-top EGREGIOUS. Pigs get slopped, hogs get slaughtered. I cold-called a local electrician who said his rate is $300 first hour. Local hardware store referred me to an electrician who sometimes works there. His rate: just $125. Based on my experiences, I will do no further business with Connolly. For any future service required, I will use other sources. Connolly customers should consider my negative experiences and rip-off pricing. Curiously, the water heater is working ... sans replacement breaker. When-if fails again, with benefit of YouTube videos and guidance from a friend experienced with electrical things, I will replace the defective breaker myself.

My husband and I needed to get our ancient HVAC ducts replacements since they were full of holes…read more John from High Performance referred me to Tri-City as the only company that he'd trust to do the work. Let's get real. It's really difficult to find companies that will do honest, quality work on your house. I'm sure we all have stories of not so great experiences. HVAC work is expensive so getting it done right is paramount due to the cost of the investment. To sum up our experience with Tri-City: this was one of the top experiences my husband and I have ever had with any vendor doing work on a home in our entire life. In an effort to do some due diligence on my part, I contacted 2 other HVAC businesses which had top ratings on Yelp in my area. Tri-City and these other 2 HVAC companies all met me in person to do look around to quote the work. I took many notes on each of the visits to record what each of the companies was recommending, along with other professional tidbits that they shared to demonstrate their knowledge. Selecting Tri-City as a vendor was a total no brainer for us. From the get go they were friendly, forthcoming, honest (which is so key), and professional. Out of all the vendors they were the only ones willing to REALLY look around in an effort to assess the work properly. They pointed out a few things we hadn't even noticed about our ancient system. From the beginning of our meeting it was clear they knew what they were doing and what they were talking about. With each of the 2 other top HVAC companies (which I won't name in this review), I had caught them being dishonest in their assessments. Each company lied about certain things in an obvious attempt to upsell work. Queue major eye rolling. It was really entertaining to see them suggest work be done which didn't make sense or make up lies about current/upcoming restrictions of what we can/cannot purchase in our county. When these lies came out I did my best to put on a poker face/act normal even though it just didn't make any sense. So although the other company's quotes were lower than Tri-City I didn't trust their estimates/quotes and knew I'd have to deal with major BS once work commenced. The likelihood I'd get surprise additional costs was pretty high which ultimately made all of the quotes even in cost between all 3 companies. The used car salesmanship attitude from these companies which were supposed to be "5-Star" companies only solidified our decision to hire Tri-City. Tri-City never attempted to milk us as a customer and we both greatly respected their transparency. They're real honest businessmen who stand by their work. That decision did not disappoint! Since we had asbestos wrapped ducts the abatement company Tri-City teams up with came first to take out all of the old ducts. Just like with Tri-City the asbestos company was professional, on-time, and clean. The work was done well and I appreciated that the company really made an effort to be careful with the dry wall around some of the wall vents. We were concerned that we'd have to do major patch ups of dry wall but in the end didn't have to b/c of how meticulous they were. Tri-City came in each day, completed quality work, and kept me abreast of their progress. When my husband requested pictures of their work in our crawl space they happily did that with no questions asked. They went out of their way to pick up new filters for us as the ones we had weren't optimal for our system (which we didn't know). Also they did an incredible job installing 2 new wall vents in the bathroom which is finally allowing heating/cooling into our bathroom! The caulking was done so well. The sign of a really great business is when they leave your home as clean or cleaner than when they came in. Each day Tri-City left our home spotless throughout the multi-day project. Our system is working so much better with the new ducts. If we ever need any installation work done in the future we will not hesitate to reach out to Tri-City for help. Thanks for the awesome HVAC work you did for us! We are truly happy with the work.

I can't say enough good thinks about John and his team. I…read morecalled John after I had someone come out to fix a problem with my Trane furnace and told me the whole thing needed to be replaced. I was skeptical since the system wasn't that old. As the official Trane dealer for the east bay I thought I'd reach out to Air Performance and Heating for their opinion. John was awesome, he was also skeptical that it needed to be replaced, and he was able to consult with me over the phone and asked me to try a few things and spent time with me to try to fix it (all free of charge). Ultimately I did need to replace the system, and John concurred but only after trying a number of different things (all for free) which I was super appreciative of. When I decided to replace it, I asked John for a quote. He prepared a quote with high end and more budget friendly options. His quote was competitive with other companies, and given his great investment in helping me, and the great warranty he offered, we decided to go with him. On install day the team showed up at 9 (right on time) and worked all the way till 8 pm. They were professional and very nice, they communicated to us well, and their work was very clean. They even found a few ways to come in under budget. They came back the next day to finish up and test out the system, and again they were a pleasure to work with and have in my home. I am really really happy that we chose John and his awesome team. We will definitely use them for any future work and I highly recommend them for anyone looking. Thank you guys!
