Joe responded quickly to my request for a quote, explained the options available to me and gave me advice in how I should approach. I was wanting to add a zone for HVAC. The price was fair and he could deliver this week, so I went for it. His team installed and was done relatively quickly. He tested and confirmed functionality. I waited a few months to give this review as I wanted to make sure that I was happy. I am more comfortable in my house now with the same or less energy used for heating and cooling. I would recommend Joe to my friends. read more

So this company had come within 24 hours to my parents house in Newark. This is service that is lacking in many areas. Joe our service tech was explaining issues with the AC unit, he was clear and we understood what he was doing to recharge the unit. Hopefully we do not need him to come back if the unit does not hold 10 degrees sub cool. He also replaced the furnace filters. Moving forward this will be our go to HVAC company. read more

Joe responded quickly, arrived on time. Quickly diagnosed issue and fixed issue. Price is good too.

Talk to Jojo and let him know that my daughter's HVAC unit which is on the roof kept blowing a fuse. So he came out took out the fan blower. Check the compressor and replace the disconnect. I feel super confident that this time it will work compared to those who have come before to fix it. Truly, a man of integrity and I would highly recommend the great quality of work he performed. I believe he went above and beyond to make sure it will stay running even though it's an older unit. Lastly, he did it for a price that I can't mention. Know that the value of his work is good. read more

Joe is the person to go to for HVAC issues. He came by as promised to troubleshoot the problem and returned later that evening to replace the part. Really appreciated the extra effort to ensure that we have heat during the night! read more

Giant came to take a look at my heater to offer a second opinion. They were very professional and put my mind at ease regarding its condition. I would definitely recommend and contact them again if the need arises. read more

I reached out to this company due to the good reviews and it being a local business in Fremont. The A/C at my rental property was acting up, and I was worried about causing unnecessary disruption to my tenant. Joe responded promptly and helped coordinate with them to get the job done. It was relatively painless and fairly priced. I would recommend Giant HVAC! read more

Joe from Giant HVAC is a customer-focused expert in all things HVAC. I've been fortunate enough to use him to recharge and check my A/C unit and ducting. His advice and expertise resulted in my unit running more efficiently. I highly recommend Joe and Giant HVAC!! read more

Joe and his crew installed an air conditioner unit a few months back and we couldn't be happier. After the estimate/quote- we agreed upon a service date and they completed the job within a day. Even after a few months of working properly - there was unforeseen issues with the unit. Joe immediately sent his crew to update and fix the service back to normal. Since then it's been working properly with no problems. They are very responsive and can turn around either a call/text or visit quickly. We highly recommend this company to anybody looking for air conditioner services. Thank you read more

Joe is incredibly knowledgable about all things HVAC. And being super responsive really helps. He supports both Carrier as well as Gree. Gree is a fairly large player in the HVAC space and is a very cost effective option for folks looking for alternatives. read more

I'm writing this review in hopes that Joe will stop texting me with his revisionist history and seemingly wanting to argue and gaslight me. Since my past two reviews, I've found a different AC contractor who was much more professional and fixed the AC issues - my AC is finally working again. Separately, pest control has fixed the rat issue as well. To be clear, I have not been in direct contact with Joe since August 2023, and out of the blue, Joe texted me yesterday (5/30/24) claiming to apologize for not being able to help fix my issue last year, and also asked for more details about what was wrong with the AC and how it was fixed. I gave Joe multiple chances last year to come diagnose and fix the AC, and not only did he brush me off as I stated in my previous reviews, he was also quite rude in going about it (e.g., gas lit me saying he'll get to it when it's convenient for him and when he's nearby - and he didn't have any projects in my area any time in the near future). I explicitly asked Joe what he wanted from texting me yesterday, and after two days of back and forth texting, he still hasn't shared his reason for reaching out to me. Instead, our texts basically became a rehash of Joe being defensive, gaslighting me, not taking any accountability, and either misremembering or outright lying. For example, Joe publicly claims to never ask people to give Giant HVAC 5-star reviews... when in fact he badgered me and asked me multiple times to write a 5-star review when the installation was just completed a few years ago. He even texted me to omit "any of the bad stuff" - referencing the multiple issues we experienced during the installation. To Joe: as I know you're reading this based on the multiple responses you made to my previous reviews, please let me move on. If you do contact me again, please be clear on what your purpose is in doing so. I don't want to rehash what's transpired. As I've stated to you several times, until you're willing to take accountability or admit your errors, us rehashing what happened is non-productive and is a waste of both of our time. Also, Joe's response (below) claims that I posted false information - in an effort to debunk my overall review, which reflect Joe's style of defensiveness and communication. Specifically, in my second Yelp review, I noted that Joe's team installed the outdoors AC unit upside down - which was a typo. Joe's team actually installed my attic AC unit upside down (this was in my original review). Everything else is factual and accurate. read more

Joe was quick doing his assessment, and did the service quickly and efficiently. He became my new go-to for any HVAC problems in the area.

We've decided to replace our furnace after the 30 yr oldie is not working properly. Joe has been very responsive throughout the process. He came over, took a look and gave us a few options. He sent us the proposal with all the options next day. After we decided what we needed, he got the required permit from the city. Joe did all the paperwork, permit application and stayed through the city inspection too. It was a quick and hands-off process for us. The actual furnace replacement took one day. The team did a great job and good communication with my husband about any concerns. The price is fair as average. The services and experience exceed my expectations. I highly recommend Giant HVAC. read more

I highly recommend Joe! He came over to provide a quote to install zone to our existing AC unit since we thought we weren't getting much flow on the 2nd floor. We replaced our filter before he came and turns out, it did the trick! He was so nice and double checked my husband's work- we had it placed incorrectly and he helped us fix it. He also explained why it was important to replace it. :) Appreciate his time and help! read more

Even in a very busy summer, Giant found a time to look at, and FIX, my air conditioner. Excellent service.

I would highly recommend Giant HVAC company for your heating and AC needs. My 25 year old Carrier AC's and furnaces needed replacing after failing. The owner, Joe, came to inspect the house for the bid. It's a family owned business. The service is personalized. He was professional, knowledgeable, and friendly. He offered several potential solutions that I had not considered and several levels of cost options for us to think about. The other companies I had bid on the job sent me one quote and gave me one solution. Joe was available by phone and text to answer questions. All my questions and concerned were addressed fully. The work was done in a timely fashion. The installers were hard working, professional, and polite. The work site cleaned up. I felt worry free. I am very pleased with my new AC's and furnaces and the work done by Giant HVAC. For a good experience, I encourage you contact to Giant HVAC for your HVAC needs. 510-624-4268 read more

Our furnace went out had to get it fixed ASAP I called Joe Saturday morning and he came out same day ! He is a gem And will be our Go to for our HVAC needs. Very reliable and honest . He didn't gouge on the pricing straight to the point and very informative on the problem .Thank you again ! read more

I really enjoyed working with Joe. He was so easy to talk to and explained everything in layman's terms for me. He went above and beyond by offering to remove our extremely old furnace (at no cost). Unfortunately, that sucker stayed put because of its awkward location in the crawlspace, lol. It was so kind of him to offer though! Anyways, he helped me install a brand new furnace and A/C unit, all to code. We easily passed the HERS test and the inspector signed off on their work without issues. Joe offered the most fair pricing of all the contractors that I spoke with. He was honest about the performance of the system given the type of house layout we had (potential for some areas with poorer airflow). Nevertheless, the finished system kept us comfortably cool during the hot summer months, and we are grateful for such a luxury. I can't wait to turn on the furnace and see how cozy it'll be this winter! The entire install took two days. The work was clean and aesthetically pleasing. They really thought about the location of all the vents, supply, and returns. Such professional workmanship. I highly recommend Joe for your HVAC needs- his pricing is competitive; he has excellent communication with his customers; and his team does great work. read more

Giant HVAC - It was tricky to place the condenser in this spot, but Joe's team figure out a clever way to run it through the crawlspace. Kudos! - Heating & Air Conditioning/HVAC Near Me - Fremont, California

The people at Giant have some of the best customer service I've ever experienced. I'm pretty well traveled and have lived in many different places, they are top notch with good prices! Love the family feel as well read more

Called Giant HVAC for a quote for a new heat pump and ducting. We scheduled an appointment for the next day at 10-11 the next day. At 10:15, Christine called and left a message that they were running late. I called back and said it was fine to come later..she said closer to 12:30 over the phone. I called them between 1:30-2 a few times and clearly they decided to ignore my calls. I would have been OK to wait longer, it would have been nice to not have to sit around waiting for them for over an hour during the rescheduled time...and for them to at least let me know they couldn't come at all rather than ignore my phone calls. At 2pm I decided they weren't coming out at all. Thank you for wasting my day. Completely unreliable. read more

Giant HVAC - Originally scheduled time, rescheduled time..and time stamp that at 2pm they STILL didn't show up and started ignoring my phone calls. - Heating & Air Conditioning/HVAC Near Me - Fremont, California

Our 40 year old gas furnace died and Joe came out to give us an estimate on a replacement. First thing, he wanted to try turning it on to see what might be preventing the blower from kicking in. He could tell from the sound that it was getting a signal, and was able to diagnose the problem and get it started. He agreed there was no need to replace the furnace and was hopeful it would get us by until we were ready to install a heat pump and go solar. His skill and honesty saved us a lot of money (and kept us warm in the meantime!). I can't recommend him highly enough! read more

Words I thought I'd never say - had the best experince installing AC unit! Joe does a great job assessing the scope of work and makes reccomendations on brands, materials, improvements/alterations keeping cost and performance in mind. His team is super easy to work with, communicate well, respectful of your space, and the best part: finish the job on time!! i'm praying that my 30 year old furnace never breaks, but if it does, I know exactly who I'm calling. Thank you Giant HVAC! read more

Joe is AMAZING! If I could I would give him 6 stars I would. First things first, if you expect that the he will do all the work himself, thats not a realistic expectation when it comes to communication and followup, Joe is amongst the very few contractors who is at the top of their game. He is very clear and upfront about setting expectations and then meeting them. I had to travel out of country half way through our project and Joe had offered to come and resolve any issues. Our project was complex and involved replacing single zone HVAC system with a 2 zone Heat pump based system. To make thing more interesting we had to add a new return from the second floor which made the project pretty custom. His team's workmanship is as good but that is to be expected, but following up and mitigating issues when they do arise, because parts fail, things happen thats when Joe shines through. read more

My parent's AC finally gave out after 20+ years...it was time for a new one. I hehlped my mom locate a vendor by searching for locall vendors through yelp. We had a few quotations from local vendors but some were either ovrpriced, never followed up or had hidden fees after the fact when asking additional questons for specified work to be done. Joe was kind enough to prepare an easy to understand quotation selectingi the best option that was best for us. Additionally, the expectations were set ahead of time as some ductwork along with some other minor repairs "may or may not" be required -- but we wouldn't know until the work started. However, he Joe was very upfront about the work that he couldn't do or was not an expert in -- so that was helpful to know in advance so that we can consisder any additional separate costs that may be incurred as part of the AC overall replacement. My mom was very happy with Joe's work as they were very thorough and professional. They cleaned up after all the work was done and Joe even came back to do a quick check and make sure everything was working as intended. He is very patient and spent some time with my mom to show her how to properly handle configurations and filter of the new AC equipment. Definitely recomment Giant-HVAC if you need an AC replacement! read more

I initially contacted them for a new hvac system including all new duct work in Nov 2022. Existing house had wall furnaces. Joe responded quickly and was able to provide a competitive quote. I delayed the project and finally got the installation done in Mar 2023 but Joe was nice enough to honour the same price. Installation was quick. Took them 3 days and all permit related paper work and inspection scheduling was done. Highly recommend them. read more

Joe and his son came to our house this past Friday on time to help diagnosis and repair our AC. Joe did a great job with quality work at a great value. We will use him again. read more

We got quotes from over a dozen different HVAC companies in the east bay to install a mini-split air conditioner in our loft. Some of the vendors we spoke with told us our project was "too hard" because of our building's layout. I'm glad we were eventually referred to Giant because Joe and his team aren't afraid to take on challenging projects, and they have the skills to deliver great results. During the proposal process, we asked a lot of questions and Joe's expertise is what really sealed the deal. He provided thoughtful, detailed responses that helped us to feel confident with the investment we were making in our home. Pricing was transparent, fair, and honest throughout. For the 2.5 day install, the Giant team arrived on-time, were exceptionally polite, and kept their workspace tidy. We appreciated how diligently they followed COVID precautions in order to keep everyone safe. We're very happy with the result. After living in Oakland without a/c for over 15 years, we finally have some cold air for these increasingly hot summer days! read more

Joe and Giant HVAC are simply amazing. I searched everywhere and got 6 quotes. Joe was very patient and extremely competitive! He revised my quote several times based on us exploring different options. He is super knowledgeable and took a ton of time to explain all of ways we could add A/C to our upstairs and downstairs. Don't hesitate to call him today! read more

Joe showed up the same day and fixed my issue. Great communication, friendly, good work. I would highly recommend.

Joe is excellent. He came via a home warranty call to diagnose my furnace issue. He even came out on Saturday to replace the board on the furnace which was the issue with the AC and heater. He explains the issue so well and has excellent recommendations for energy efficiency. Highly recommend Joe and the work he does. read more

With summer coming up and a new baby on the way, we knew March was the best time to get central cooling installed, since our wall unit didn't quite cut it during the last summer. I reached out to a few different vendors to get cost comparisons. Joe was responsive and quickly set a date with me for the initial walk through. For all of our meetings including the initial quote, he was reliable and timely. We saw from the initial walk-through that he was knowledgable; he asked great questions and brought up useful considerations for us to think through. We felt confident about his experience and expertise in working in this field. And, his pricing was very competitive as well. After signing the contract with him, he estimated 2 days of work, and got all work done by the early afternoon of the 2nd day. He helped partner with us for the city inspector who came through as well, which we very much appreciated. We had a great experience with Joe and his team. Joe is a proactive communicator who demonstrates his expertise through his work and thoroughness. He's always forthcoming and honest. We would work with him again and strongly recommend him for the great work in our AC installation. read more

Had issues with my AC. JoJo was very professional and provide great assistance over the phone. I have two kids and my wife wanted to make sure with all the COVID-19 precautions that JoJo was able to meet those standards. JoJo listed out what he had for safety measures and gave detailed description on how he would accomplish the task end to end. Those details my wife did not hesitate to request his service. JoJo came on time and was in and out. Pleasant experience during these crazy times. read more

Joe was great to talk to on the phone. Initially, I asked him to install previously purchased equipment. Pretty much no one does that. We spoke a few times and he was so helpful and did such a good job teaching me about his recommendations, I knew we should just hire him to do the job the way he advised. I'm so glad we did! He holds very high level certifications and obviously knows what he's doing. His team communicated well and was friendly. They rolled with the punches on a new build project with frequent stops and starts that was way less than ideal for them. They stayed cool, calm, collected, and professional. We really appreciate their service. read more

My 20+ years HVAC system failed and I thought it's time to replace with a brand new system. I called several contractors and Joe from Giant HVAC responded very quickly and he even suggested that he could come over to give a free estimate on the same day. very quickly he gave me a very thoughtful and comprehensive estimate with several options to consider and guided me through what would be the best solution. and also his pricing is reasonable and he even promised five year warranty for labor and parts for a brand new system. we agreed on the estimate and he was able to order a brand new Carrier system and scheduled the installation next week. On the day of installation, he and his team arrived on site right on time and did a very nice and smooth installation and finished everything nice and clean. I am very happy with Hvac's professional work at the job and Joe is the owner of the business and he's very professional, friendly, responsive and making sure that his team has done an excellent job. It was a very good experience and I highly recommend GIANT HVAC. Again I very appreciate the nice job by GIANT HVAC! read more

We called Giant HVAC to provide an estimate for replacing our failing Heater and A/C system. Joe responded quickly and went out of his way to provide an estimate over the weekend because of a time constraint we had. From the start he presented himself professionally and was very attentive to our needs and concerns. He responded with an estimate with Good-Better-Best options and a clear description of work. The prices he quoted were fair, and often lower than other companies. He was among our top choices. We ended up choosing a different company that carried a specific brand of equipment that we were interested in. The kind of professional experience and help that Joe provided us was top-notch--he is a pleasure to work with. read more
