I had an issue with an older A/C unit that multiple other providers looked at and couldn't figure out. Giovanni came in, diagnosed the problem, and found a creative solution that actually worked -- no "you need to replace the whole unit" runaround, just genuine expertise and a willingness to think outside the box. What really stood out beyond the technical skills was how accommodating and flexible he was throughout the whole process. He worked around my schedule, kept things stress-free, and was friendly and easy to talk to from start to finish. You can tell he actually cares about doing right by the customer rather than just closing a ticket. Global Heating and Cooling Services has earned a loyal customer. read more

I had a great experience with Global and highly recommend them! An air duct under my house had disconnected from the vent in a bedroom. Johnny responded incredibly quickly, arrived promptly and had everything fixed in about 15 minutes. What really stood out was his honesty and fairness with the effort that it would take to fix this problem and the pricing-- he only charged the minimum service fee. Other companies had quoted me anywhere from $300 to $500 for the same job. It's rare to find a company that's this responsive, efficient, and trustworthy. I'll definitely be calling them again for any future HVAC needs. read more

John is very friendly and knowledgeable. He showed me the inner workings of my units, and did a great job explaining what the issue was. I felt that he was honest, and wasn't overcharging me. There are so many HVAC/AC companies that are available, I'll call them next time for sure! read more

We've trusted John and his son Giovanni for many years. From new systems to checkups and repairs, this is exactly the focused, experienced, responsive and reasonably priced service that is so hard to find. read more

Our furnace stopped working on a Sunday. I put out a project request on Yelp, and within minutes I got a call from Global. Giovanni (the owner) told me about his business (family owned and operated), and that he could have Joey out to do a diagnostic the very next day. The visit is $49, which will go towards service if we go with his company. I also made an appointment with another HVAC company, which had a $89 visit fee, the following day. Joey arrived on time, checked out our furnace and knew exactly what the problem was. Since our furnace is old, he'd have to order the parts, but he gave us a fair estimate. He was very professional, and was very confident what the problem was. He didn't try to up-sell us a new furnace. This left us with such a good impression that we decided to go with Global, and cancelled our appointment with the other HVAC company. I don't usually have service done on our home without a second quote, but that's how confident we felt with Global. We got text updates from Global when the parts were ordered, and when they arrived. By the following Monday, Joey came back to install the new parts, and everything worked like a charm. Our experience could not have gone any smoother. Highly recommend. read more

They provided great and fast service. Will definitely use them again in the future. Ac is working great after a bad capacitor replacement

Our AC unit stopped working, as the refrigerant had leaked out. Because the uni was 16 years old, the best option was to replace it with a new one. Global ordered the parts, created the building permit, and scheduled the installation within a week. The installation team was well-organized and worked hard to complete the job in a few hours. They did a quality job at a reasonable cost. read more

Highly informative and skilled staff, did the repair project quickly and with excellent quality! We absolutely recommend John and his crew.

John is a very knowledgeable and honest person. He helped in our furnace valve replacement work a month ago. On time, reasonable prices, and great team. Thank you! read more

Rating: "I couldn't be happier with the incredible service! From the very beginning, the owner, John, was personally involved and made sure I had a clear, fair estimate without any high-pressure sales tactics. It's rare to find an owner who cares that much about the details and customer satisfaction. He went above and beyond, jumped through loops to fetch a permit, and had a broken furnace replaced and running within days during the busy Thanksgiving week! The installation crew was equally impressive. They arrived exactly on time, worked tirelessly, and were extremely respectful of our home. John and his company coordinated our inspections and made this a stress-free experience! This is a top-tier honest team that truly takes pride in their work!! We HIGHLY recommend!! read more

If you are looking for someone to service your Heating or Air Conditioner system at home or business, I highly recommend Global Heating & Cooling Service. I initially spoke with Giovanni(owner) when I requested a quote. He came out the next day and was very knowledgeable but more importantly he values honesty and integrity when he deals with customers.... It's rare to find businesses who cares about what's in the best interest of the customer. I will always give my business to trustworthy people. thanks again Giovanni for helping me save $500 in repair cost. read more

I had my heating system replaced in my two-story home. John came out and gave me an excellent quote estimate. I went with this company because I had previously had them serviced my old unit and they were great to work with. They installed a new system within a day and all the employees are very friendly, helpful, and understanding of all my questions I had. The new system is excellent. read more

Very quick and professional service -- fixed the issue within 30 minutes at a reasonable price. Highly recommend!

Had Global come out for A/C maintenance. Very knowledgeable and good price. Will definitely keep them in mind for future projects!

Amazing Service - Highly Recommend! John from Global Heating and Cooling Service was fantastic! My AC wasn't cooling at all yesterday, and the temperature inside stayed at 85°F during the peak of summer -- it was miserable. John came out, diagnosed the issue quickly, and had everything fixed within an hour. He made sure the system was running perfectly before leaving. Super professional, fast, and thorough. I really appreciate the great service. Thank you, John! read more

Global Heating And Cooling Services - Ac unit in my balcony - Heating & Air Conditioning/HVAC Near Me - San Jose, California

They were so fast, efficient and reasonable priced. I remember callling them during a crunch when our first furnace broke and they did a great job (Carrier 2 stage 7.2 BTU) Recently, they replaced our upstairs furnace with an ultra low nox furnace. Did a fantastic job and they billed me for the exact amount of their upfront quote. They was efficient and on time. Lastly, they did a very good job cleaning up after their work was done, which I liked a lot. Thanks guys! Well done. read more

Super helpful and kind. Sprung into action and told us how to handle a potential leak with PGE while they came out. Had to replace the furnace and they offered my tenants space heaters in the interim as well. Professional, reasonably priced and honest. Would recommend and will definitely be coming back for any future repair needs. read more

Great experience with this local, family-run business. They recently installed a new heat pump for us right in the middle of a cold weather, and the process was smooth from start to finish. Their communication is top-notch; they responded to all our questions almost immediately, and their pricing is incredibly fair. It is rare to find such a dependable and honest team. A huge thank you to John for the outstanding service--I highly recommend them! read more

After calling 3 different heating and cooling companies I decided to go with global and they did not disappoint. I made an appointment and technician was able to diagnose the issue within minutes. That to me shows that they are experienced with that they do and not try to upsell you with services you don't need.. just straight to work, it was some sort of sensor that needed replacement. I asked him to look at the other sensors on the furnace if they need replacement and he said the other ones are all good. Trustworthy people that have good business practices and they are now my go-to for any heating/cooling repair. read more

Simply put old school ethics and expertise at its finest. When your AC predictably fails on the hottest day, you want it repair ASAP but is afraid of how much it will cost you, you certainly don't have high hopes of a cheap fix after hearing the local AC company will charge you a diagnostic fee of $69 just to have a look and is cagey on pricing and repair option. Global Heating And Cooling does none of these things, is very reasonable on repair costs and will help you with trouble shooting advice even if you don't end up using their service. a rarity now days. Contrary to marketing presentations, the modern AC system differs very little fundamentally from its predecessor 70 years ago apart from some modern electronic control boards. The external unit remains that of a sealed reciprocating compressor power by electric motor pumping Freon through a condenser that is in turn cooled by external electric fan all controlled by a mechanical contact relay. Just like an old school fridge, a experienced technician can quickly diagnose most problems here given a reasonable description from the customer and some photos. Most AC company today will charge you for the above privilege or outright hide info here. Not so with with Global Heating And Cooling ! They were upfront with potential costs on replacing different components, how to quickly locate key info like fan RPM and quickly diagnosed a bad start capacitor from from photos and verbal description despite yours truly lacking a multi-meter. Thanks to the above, the repair bill was cut from $275 to $27. Not many vendors now days will freely give out technical advice to customers that costs them revenue ! For the above episode, i fell compelled to share my experience with fellow Yelpers and whole heartily recommend Global Heating And Cooling. read more

Joey helped me with a 30 year old furnace repair that had a bad control board. The parts are hard to come by but he was able to source one and installed it very quickly and we got the heater back up and running and in comfort during the cold weather. This is the second time I've worked with Global and both times were very professional and above my expectations! The value is excellent. If you're looking for a Heating and cooling solution, go with Global! read more

Arrived within couple of hours and fixed the issue with filter and very nice person as well

I found Global Heating and Cooling through my neighbor, and I'm so glad I did! From start to finish, the entire process was smooth, professional, and stress-free. Right from the first conversation, John listened carefully to what I needed and wanted. I was especially concerned about keeping the unit in its original location and not having to relocate it to the backyard - and they totally understood. After inspecting my setup, John offered a replacement plan that checked all the boxes and provided a very clear, reasonable quote. What impressed me most was how easy and seamless the whole process was from start to finish. And I ended upgrading to a heat pump instead of replacing my AC and furnace separately, which turned out to be a great choice for my home. Just a few days later, the installation was done - within a single day! The crew was professional, efficient, and respectful of my home. Everything went off without a hitch. If you're looking for honest, knowledgeable, and reliable HVAC service, I can't recommend this family-run business enough. A truly excellent experience! read more

See all

I contacted John for a failed pressure sensor in my furnace. He was very prompt in response and reasonable in his quote. He adjusted his schedule to accommodate on short notice and took care of the issue very next day. He was communicating well throughout the process. Some fun in the conversation is a bonus. :) Happy to work with him again and Highly recommend him. read more

Had the team (Joey) come out to check the AC before the San Jose heat sets in! Joey was prompt and got everything checked out within 30 minutes! He also cleaned the grate where the air filter was placed, and checked on the part that he replaced two years ago to make sure everything was still in working order. Will definitely use this service again! read more

John and team were fantastic to work with. Prompt, efficient, and professional. Were in and out on time, and performed excellent work. We very much appreciated John's recommendations and honesty. Highly recommend! read more

John is responsive, knowledgeable, honest and charges a fair price. What more could you want. I'm keeping his number in my contacts list. I don't provide Yelp reviews often. I felt compelled to write this on. I highly recommend John. read more

Global Heating And Cooling Services - Heating & Air Conditioning/HVAC Near Me - San Jose, California

This review is for Global Heating and Cooling Services. Our old Carrier furnace had been making a loud, intermittent noise for some time. We had another business (also with good Yelp reviews) come to check but they sadly did nothing more than a quick look and say all was good. Thus, we weren't sure what to expect when we called Global. Joey came out and within a minute or two noticed an issue with the motherboard LED and after hearing a recording of the sound concluded a failed motherboard was cutting power to the furnace and the sound was from the blower motor suddenly turning off. The next day we installed a new motherboard. Upon inspecting the old one sure enough there was a burnt component on the backside. Our system has been running since without the power shut-off and the cycling seems improved. In hindsight the other company should have caught this problem. Joey was quite honest, knowledgeable and helpful, explaining what he was doing and answering our many questions. Joey is John's (Giovanni, the owner) son and Global is a small family business. After working with Joey and talking with John they are both focused on providing good work and customer service. Somewhat hard and refreshing to find these days. In short, Joey and Global were great and I have no reservations about giving them 5 stars and recommending them to others in need of furnace or air conditioning work. We did not have it done but they also do duct cleaning. In fact, Joey has his own company doing duct cleaning throughout the Bay Area. Thanks, guys, you helped lower our blood pressure and keep us warm! read more

Airconditioner condenser cooling fan was not starting, after checking he found the capacitor is malfunctioning. so replaced it and it started working. He came on time , checked and fixed efficiently in short time. Job well done! read more

Very professional and prompt service. John was very responsive in the initial call. Heating was not working at my tenants place , John scheduled a diagnostic service for the same day. Upfront about the fees. They waive the diagnostic fee if you get it repaired the same day. I chose to get the thermostat replaced since it was not cooling the home. Joey did a great job ! Very happy with the service and will be using them for all my future needs. Definitely recommend them with no hesitation! read more

My AC conked out so I requested a service. The customer service is top notch, and the work was fast and efficient. Also, I found that the pricing was more than reasonable. No complaints and I will be recommending them to others. read more

Joey did an amazing iob diagnosing the issue of my furnace. He quickly figured out the issue and fixed it.

Global Heating and Cooling services installed a new heater in our attic, which is particularly tricky to access. They did a great job, had great communication, and we were really pleased with their work. In the last few years we had a couple of times when other house repair people messed with the gas/heater causing the fan in the heater to keep going. We called Global Heating and they QUICKLY jumped on it and got it straightened out, (one time just instructing me how to take care of it over the phone saving me paying for someone to come out). Not all companies would do that. EXCELLENT customer service, work and communication, which has built trust with us. Highly recommend. read more

Super fast scheduling and awesome service! One of our AC units wouldn't shut off except at the breaker. I texted our usual guy, but he let me know that he had moved out of the area but that his friend, John, was taking care of all his local clients. I called yesterday afternoon, figuring that it'd be a few days before they could fit us in. To my surprise, they were able to schedule us in for this morning, and Joey called to confirm he was on his way today. He got to work right away, replaced the broken part, made sure everything was working as it should, and was out even before our scheduling window was over. He was very professional, and we're happy to have our AC in tip-top shape before the weather warms up again later this week. Highly recommend! read more

Global Heating continues to be a top notch company to work with. The technician quickly diagnosed the issue and was kind enough to find a time to fit me into his schedule that same day or the next. Ultimately, I wasn't available, but he showed up first thing in the morning on the day I was free and was done in about 15 min. He rushed because I had to be somewhere and could only give him a short window. I really appreciated his attention to my time crunch. I can't say enough about the service I've received and the value. Definitely give them a call if you're in need of AC or heating repairs or installation. read more

John was amazing in helping me diagnose a furnace problem and find the fix just over the phone. Tremendous customer service, availability and technical knowledge. Highly recommended. read more

Had a great experience starting from the very first message I received. I reached out on a Sunday and John came out the very next day and assessed my non-working AC unit. He proposed two options: 1) full replacement or 2) repair the broken part and refill the refrigerant as a temporary fix. I appreciated the options because I've had other companies just flat out say that there is no way to fix it or get it working. I ended up going with option 2 since it's the end of the summer season and will definitely use this company again when my AC unit eventually needs replacement. read more

Honest. That one word sums up John and his business. I contacted John through yelp and received an immediate response. He contacted me shortly after via phone and had me breakdown the issue. I had a line fuse light up as bad. Instead of jumping in to schedule an appointment, run through a diagnostic and make unnecessary repairs, John being the trustworthy man that he is explained that all I needed to do was replace the fuses. He added, if that didn't fix the issue, he would be available to come out and diagnose the problem. Sure enough, replacing each fuse fixed the issue. John could have easily run through the motions and charged me a fortune but didn't. He just earned a customer for life. I will be recommending him to anyone who needs HVAC service. Thank you again! read more

My experience with Global Heating and Cooling was outstanding. The AC at my rental property stopped working. Upon my call, John was able to diagnose the issue next day and provide me a detailed report with a reasonable quote. He also went out his way to help expedite the fix given that my tenant is pregnant and needs AC asap. I will work with John again if I ever have HVAC issues again in the future. Thank you Global Heating and Cooling for your excellent service! read more

Amazing and fast service!!! I highly recommend John, he was professional and highly efficient. He actually recommended that I could replace the broken part myself if I was handy and save a lot but unfortunately I'm not so I opted for his service. I respect the fact that he was being straight forward and honest. read more
