Absolutely Outstanding Service!
I had an amazing experience with Global Heating and Cooling Services from start to finish. The team was professional, honest, and extremely knowledgeable. They quickly diagnosed the issue with my system and offered clear options without trying to upsell anything I didn’t need.
I ended up doing a full A/C and furnace replacement, and the work was done on time, on budget, and with zero mess left behind. The technician explained everything clearly, and I really appreciated the transparency and attention to detail.
You can tell they genuinely care about customer satisfaction—licensed, bonded, insured, and their free diagnostic with repair offer is a great bonus.
If you’re looking for trusted HVAC experts in the San Jose Bay Area, Global Heating and Cooling Services is the only company I’ll recommend from now on!
