HVAC reviews in Milpitas, California

They fixed my furnace on the same day, even though I only needed a routine check. When I stepped out for an errand, the thing worked without fail - but that didn't mean everything was okay with it. The tech took a look at the old unit and made some recommendations. It's been running smoothly since then. The company responded promptly and the technician gave me straight answers.

I was recommended to Global Heating and Cooling by a previous client who had a positive experience with me when buying their home. Since then, I've worked with them on multiple occasions for both my listings and personal properties. They're always prompt, dependable, and fair in their pricing. I'll definitely be sending more clients their way.

We hired Global Heating and Cooling for a leaky heater issue. John handled it well, was responsive to our concerns. We're very pleased with the service and would definitely recommend them for future HVAC needs.

We had a great experience with Global Heating and Cooling. Our old heater unit had an electrical problem, causing smoke to come out of the vents. A technician arrived promptly within 15 minutes to check for any ongoing issues. After diagnosing the problem, we were able to schedule replacement work on both our heaters and AC units within a week. The team was very professional and efficient, completing the job in one day. I'm pleased with how everything turned out – thanks to John and his team.

He showed up right on time, with the required components in his truck. He demonstrated the faulty parts, explaining how they failed and their functions. With some effort, he restored working order to damaged furnace parts. He also installed a new air filter I had already bought for my existing cold return unit in the ceiling - no extra charge or fuss. He went above and beyond what was expected. His service truly exceeded expectations; that's why I'd trust this company.

A technician from Global visited my old furnace after 25 years and quickly identified the issues. He laid out the repair vs replacement options and suggested the most cost-effective solution considering upcoming permit changes. He ordered parts and returned the next day to get the furnace up and running smoothly, leaving me with a hassle-free experience overall.

We were fortunate that our appointment with Joey was scheduled relatively close to the original time, considering it was slightly delayed. Upon his arrival, he efficiently inspected the heater and identified the root cause of the issue - worn-out heat sensors due to dirty filters. He promptly resolved the problem, explaining the necessary replacement steps to me, allowing me to purchase new filters myself.

Joey's demeanor was exemplary; he exuded courtesy, professionalism, and focus throughout the interaction. His commitment to his work and ethics is commendable. In contrast to some businesses that might take advantage of customers, Joey demonstrated a genuine concern for our needs.

The level of service provided by Global Heating & Cooling and their staff, particularly Joey, sets them apart from other companies. Their adherence to ethical principles is truly impressive. I wholeheartedly endorse this business and am pleased to have found a reliable and trustworthy partner.

We recently hired Global Heating & Cooling for a project, and our experience was outstanding. They delivered top-notch service from initial contact through completion. Their team was courteous, efficient, and committed to delivering exceptional results. The technicians showed expertise and explained everything in detail. We were impressed by the quality of work and the company's ability to stick to schedule and budget.

I had a decent experience with this home services business, but it was somewhat underwhelming.

The initial visit cost $95, which took around 20 minutes to complete. The technician assessed the issue and found that the Freon levels were low, recommending a $2100 refill service along with UV dye to locate the leak source.

I had previously done this work last year, thinking that finding the leak was the next step. Instead, the technician only wanted to do the refill service, which was disappointing.

He also mentioned that the compressor sounded funny and advised shutting it off, but other technicians who quoted didn't notice any unusual noise or required a pre-refill assessment before quoting.

Unfortunately, I couldn't comment on the quality of their work since I ended up choosing a different contractor. The only reason I'm giving them one star is because they refused to try to find the leak source instead pushing for the refill service.

In hindsight, it's clear that my new HVAC technician found the issue quickly using UV dye and other equipment, which had leaked into the evaporator coil cabinet from last year's work.

To anyone considering this business, I'd recommend getting multiple quotes and educating yourself on potential HVAC scams before committing to a quote. Keep in mind that trained technicians command higher prices, but there can be significant variations in costs for similar services.

I received great service from this company, which exceeded my expectations. They responded promptly to my initial inquiry and got me scheduled right away. The technician, Joey, showed up on time and fixed the problem efficiently. He was also very patient in answering our questions and explained what was going on clearly. I highly recommend them to anyone with HVAC issues.

Booked regular maintenance for my old furnace after it had gone too long without servicing. The technician gave it a thorough clean and check, and now it's running much better than before.

I hired Global Heating and Cooling five years ago to replace my old furnace with a new heat pump system, which they installed in perfect condition. From the initial consultation to the final inspection, their team was courteous, punctual, and remarkably knowledgeable about their products.

John, the owner, took the time to explain my options clearly and helped me choose a system that met my specific needs. Despite a tricky attic space with limited access, the installation went without major issues and left no mess behind. I was impressed by the team's attention to detail and professionalism.

Over the years, I've had only one minor issue - a blown fuse - which they diagnosed and fixed quickly. The system has run flawlessly ever since, thanks to their regular maintenance visits. Their latest service call was just as smooth, with the technician arriving on time and conducting thorough inspections to ensure everything is functioning at its best.

John's guidance and advice are invaluable, providing cost-effective solutions for my HVAC needs while also addressing concerns about smart thermostat usage and system maintenance. His commitment to honesty has instilled trust in me, reassuring me that I'm in good hands when it comes to my heating system. Their pricing is reasonable, especially considering the exceptional service they provide.

I've made an informed decision choosing Global Heating and Cooling for all my HVAC needs, and I would wholeheartedly recommend them to anyone seeking reliable installation or ongoing maintenance services.

We got ripped off by these guys when our AC developed condensation issues, but they were super helpful in finding the root cause - it turned out to be a plumbing error that wasn't directly related to our HVAC system. John showed up second time around and nailed it. The bill was very reasonable for just one visit. If I ever need more HVAC work done, these guys are my first choice.

I've dealt with numerous HVAC companies over the years. Be cautious of large advertised firms that send unqualified reps instead of technicians. Seek recommendations. If you want genuine service, look elsewhere. Global is one company I trust - they deliver honest work, good customer service, and support. Their card is on my furnace for future needs; I endorse them wholeheartedly.

John efficiently resolved my hot air furnace problem and emphasized the importance of regular filter replacements - this was an excellent service experience.

John was extremely responsive, especially considering the urgent nature of the situation. I described the problem over the phone, and he methodically walked me through a diagnostic process. He provided clear explanations and guidance on where to look next, which helped me identify the issue. With John's help, we were able to pinpoint the problem and get my AC system up and running again. His friendly demeanor and expertise made the experience seamless. I've been relying on John for all my HVAC needs for over a decade now, and I couldn't be more satisfied with his service.

I had an issue with my air conditioning system, but the team quickly diagnosed the problem and scheduled a replacement for my condenser unit. They were prompt and professional in their service. I've been using them for years to maintain my furnace and AC units. Their service has always been top-notch and I highly recommend them.

John fixed my Nest thermostat over the phone in no time - it's now charging again. Great service from Global Heating and Cooling Services, I'd definitely recommend them.

Contacted Global for furnace repair and they delivered. Quick response from a knowledgeable technician, Joey, who fixed the issue with the heat sensor on the spot. Our heating system's back up and running - thanks for getting our home comfortable again.

This company operates with integrity. The owner conducted a thorough diagnosis during the initial visit. I'd previously assumed they'd charge low diagnostic fees to make up for higher repair costs, but that wasn't the case. The owner is friendly and transparent - an honest experience from start to finish.
