HVAC reviews in Milpitas, California

I've been consistently satisfied with John's services for eight years, relying on him for my heating needs. His team is always quick to respond, even during busy periods. Recently, my furnace motor failed in the dead of winter - a stressful situation. Global arrived promptly with fair prices and restored my heating system.

Here is a rewritten version of the review:

My AC unit failed in September 2024, and John from Global Heating and Cooling came to investigate. The old unit was over 30 years old, but the fan motor had given out. John contacted the manufacturer and other companies to find a replacement motor, but parts were hard to come by. The manufacturer couldn't even rebuild an existing motor because they didn't produce new compressor parts anymore. With that in mind, we decided to replace the entire system rather than risk it dying if the compressor failed.

John handled all necessary permits and paperwork, and his crew installed the new system within two days. They took care to protect my floors and walls with tarps, keeping everything clean during the process. The technician was knowledgeable about the new system and answered all my questions, explaining what he was doing each step of the way.

The professionalism and friendliness of John's team made a big impression on me. I would highly recommend Global Heating and Cooling to anyone in need of heating and AC services.

John responded promptly to our referral text and arrived at our house within 30 minutes to get our heat up and running. He was on time, provided clear explanations of what he could do, and offered fair pricing for the visit. What impressed us most was when he found a hard-to-replace part - we were about to replace it ourselves, but he saved us thousands by sourcing an alternative. We wholeheartedly endorse him.

Joey arrived on schedule and diagnosed the issue promptly. The repair was completed the following day, with a fair price tag. Communication was efficient and straightforward. Overall, I'm satisfied with the service and will consider this company for future HVAC needs.

John is top-notch, hands down. Two years ago he installed a minisplit in our upstairs, doing an excellent job. When I needed to replace my old furnace, John was the only one I called - he got it done perfectly with my house's unique setup. He always responds promptly and accurately to my questions. His team does outstanding work.

The technicians were knowledgeable and skilled at replacing my furnace and heat pump adjustments. They worked efficiently and professionally, meeting my expectations. The quoted price was fair, and I appreciated the flexible installation schedule options. Their work exceeded my satisfaction levels; I'd definitely recommend them.

Here's the rewritten review:

Had a problem with my furnace - faulty pressure sensor. Got a quick response from John, a fair quote, and he fit me in on short notice. Next day, issue was resolved. Communication was good throughout. We even had some banter, which made the process more enjoyable.

I'd work with him again and would definitely recommend him.

Great experience with this company! Installing our new heat pump in freezing temps was efficient and expertly done. Prices were reasonable and customer service was superb - we felt valued as customers. If you're looking for a reliable HVAC provider, stop searching, they're it.

I reached out to John on Tuesday night via text and got an immediate response, scheduling him for the next day. He arrived ahead of schedule, fixed the furnace promptly and charged me a very fair price - much lower than I anticipated. While he worked, he also discovered a leak in the hot water heater supply line. This unexpected finding was a pleasant surprise. Overall, it was a great experience and I'll definitely be using Global again.

John booked us in on short notice when our furnace and water heater failed, and quickly identified the problem. Although the furnace needed to be replaced, he prioritized fixing the water heater for the same day. His crew came back the following day to complete the furnace installation. The technicians were courteous, efficient, and did a great job. I'm confident in their abilities, so I'll likely call them again when we need assistance.

I've finally found a reliable heating and cooling company after calling three others. Global exceeded my expectations, starting with their prompt appointment process. The technician quickly diagnosed the issue, which impressed me as evidence of their expertise and focus on getting the job done rather than pushing unnecessary services. Upon further inspection, I discovered that only one sensor needed replacement, but the rest were fine. I appreciate their transparency and straightforward approach. Their professionalism and business practices have won me over, making them my go-to for any future heating/cooling repairs.

Victor gave our home a thorough check-up, inspecting the AC unit, thermostat, air filter, and ductwork. He's knowledgeable and presented himself professionally. His pricing was fair, and we'd be happy to hire him again.

Victor showed up promptly and demonstrated expertise in his work. He clearly explained each step, and offered valuable maintenance tips for the AC and heating systems. The extra guidance on filter care was particularly appreciated.

I owe a huge debt to Alberto from All Heating and Air Conditioning - he saved me from a sweltering Labor Day Weekend. The A/C died on Saturday, and I thought I was stuck with no help until Monday. But with some online searching, I found them and gave them a call. They squeezed in an appointment between 12 and 2 on Sunday, and Alberto arrived right on time at noon. He fixed the problem in under 20 minutes and got my A/C up and running again. I'm eternally grateful to Alberto and All Heating and Air Conditioning - they were the heroes of my weekend!

Woke up on Monday to find my fridge and freezer broken, with ice melting all over the kitchen floor. Called a company that day, and a technician arrived at noon - fixed everything in just 15 minutes. Impressed by their speed and price. The service was also friendly and professional. That's about as good as it gets for customer service.

The technician arrived promptly to diagnose the heating issue, which was the thermostat. They presented alternative solutions to fix it. Victor was highly competent and transparent in his work. His professionalism and integrity impressed me. I'd wholeheartedly suggest him to anyone facing a similar problem.

The team arrived promptly and performed a diagnosis on the spot, fixing the HVAC in under an hour. Victor explained everything clearly and kept me informed throughout the process, which was greatly appreciated on a sweltering summer day.

Victor and his colleague delivered exceptional work, moving at a swift pace while remaining composed and patient. They covered every aspect with clarity, answering all my queries and addressing my concerns thoroughly. Their professionalism was outstanding, and I'm impressed by the high caliber of your team.

My old heater finally gave up the ghost. Instead of trying to patch it up, I figured it was time for an upgrade. The problem was, I had no idea what I was getting myself into - brands, models, prices... nothing. So, I called around to get some quotes from various companies.

"All Heating & Air Conditioning" showed up on time and gave me a solid quote. They walked me through their options and explained the differences between them, even helping me understand how the heaters work. It was reassuring to have someone break it down for me. The installation took all day, but it was done smoothly and cleanly. The new heater is quiet as can be - I'm thrilled with the decision.

I reached out to them after hours about a leaky AC, got a quick response from someone named Victor, who arrived on time the next day. The fix was simple and efficient - done in no time. They've earned my trust as my preferred HVAC technician from now on.

Victor did a great job with my AC installation. He arrived promptly, got straight to work, and was thorough in his explanations. The result is excellent and I'm very satisfied. Highly recommend Victor for any AC needs.
