HVAC reviews in San Jose, California

Porter did a great job. He showed up, offered useful advice, and I'm really pleased. The service was top-notch, and I'd definitely suggest him - he's one of the best professionals I've encountered. Thanks!

Mel and Ever did an excellent job repairing my furnace. They were pleasant and easy to interact with, making the experience very positive.

Porter was very professional and personable. His assessment of my heating issues was comprehensive and helpful. I'm extremely satisfied with his work, making him an excellent choice for HVAC services.

The technician arrived, introduced himself, and covered the shoes. He attempted various methods to get the thermostat working but couldn't succeed. He informed me he needed to contact his supervisor for a replacement due to connectivity issues with my WiFi. The service provided by Danny was commendable; he was polite and courteous throughout, making a positive experience despite the initial challenges.

Gerry showed up on time and got the job done quickly. After the AC tune-up, I had some extra questions about my vents, which prompted Gerry to give me estimates for future repairs. Overall, a solid experience with reliable service.

I had a new Lennox furnace installed, but soon discovered an issue with a faulty factory part that caused a startup noise. The original replacement provided by Lennox had a lower gas pressure, which resolved the problem. Technician Francisco came to replace the parts and everything is now working smoothly, no longer producing the unwanted start-up noise. He was professional, courteous, and did a thorough job.

Porter's visit went smoothly. He quickly assessed the situation, offered a reasonable quote, and was friendly to deal with. His professionalism has put my mind at ease, leading me to move forward with the new ductwork installation scheduled for tomorrow.

Very efficient service. I'd highly suggest A1 heating and cooling for prompt furnace repairs. They arrived promptly at 6pm, provided an estimate on the same day, and completed the installation by 1pm the next day.

I consistently choose this service for heating and cooling needs, as they consistently deliver quality work. My recent experience with Francisco was top-notch - he efficiently fixed my furnace and proved to be a pleasant professional.

I recently upgraded my home's heating system due to inadequate cooling. I was impressed by Hyman's expertise in recommending a heat pump solution that complemented my existing solar panel setup. The installation team, led by Everardo, Alberto, and Juan, were highly competent, friendly, and got the job done remarkably quickly - completing it in under 4 days.

I'm excited to start enjoying my new HVAC system.

Great experience with A-1. They had to reschedule once but when they arrived, Danny did an excellent job on the HVAC inspection. I accompanied him, observing as he thoroughly checked each area. He explained his method and offered tips for upkeep. Impressive professionalism and attention to detail.

Be cautious when dealing with this company, as their pricing can be misleading. They may initially offer a reasonable quote, only to revisit and add unapproved changes at an inflated rate. Additionally, be aware that time and material work is excessively marked up, often 3x the actual cost of materials.

I'm writing to express my disappointment with the furnace installation done by a third-party contractor for Home Depot at my Redwood City, California home on December 5, 2025.

From day one, the system has been faulty, failing to turn on frequently - especially during colder days. Despite multiple visits and repairs from our household member who was always present, the issue persists. This has caused significant disruption to our daily routine.

The repeated attempts at fixing the problem have only led to more inconvenience and wasted time. Recently, warmer weather masked the issue, but when temperatures dropped again on December 26, 2025, the heater failed once more, proving that the fix was never done.

I'm extremely dissatisfied with the outcome of this experience, expecting a reliable heating system during winter instead of weeks of hassle and an unreliable setup. I request:

1. Immediate and permanent repair
2. Replacement of the furnace
3. A refund if the issue can't be resolved quickly

I expect this matter to be escalated within both the contractor's company (A1 Cooling and Heating) and Home Depot, as their service falls far short of acceptable standards.

I urge them to get back to me soon to outline a plan for resolving this issue.

I recently had my air conditioning system serviced, which turned out to be a thoroughly satisfactory experience. The technician not only checked the mechanics of the unit but also helped me clean up the exterior and replace my filter. He took care to properly cover my newly installed crawl space protection as well, ensuring everything was tidy before finishing. As always, I've been pleased with A1's service - they consistently provide a reliable and professional experience for me.

Danny provided excellent customer service, meeting all my system needs. He also helped with two tasks, installing a new filter in my furnace after servicing my air conditioning unit.

A+ service from start to finish - quick response, efficient fix, and ensured everything worked perfectly before leaving. No complaints at all, would highly recommend this company.

A1 Heating and Cooling delivered exceptional service - fixing my wall unit promptly and going above to meet the deadline. Their technicians were courteous, efficient, and got the job done right away. I'm grateful for their swift response and appreciate their professionalism. They truly stood out from other services I've used, making it easy to recommend them to anyone in need of heating or cooling repairs.

We've had a terrible experience with A1 Heating and Cooling that's left my family shivering through months of cold weather without heat.

The company has consistently failed to deliver on its promises, with poor communication being the biggest issue. Missed or late appointments were the norm, and when technicians finally showed up, they didn't have all the parts needed for the job. Despite repeated assurances that everything was on track, we were left waiting again and again.

When the parts did arrive, it turned out they were incomplete, and we had to wait even longer for another set of parts. After those were installed, the system still didn't work, and we're back where we started - without heat. The whole process has been a frustrating cycle of delays and failed promises.

What's most disturbing is the complete lack of communication and accountability from the company. We've had to chase updates and wait for answers, only to be met with more delays. This isn't just a repair issue; it's a clear failure to resolve a known problem.

We're not just upset - we're concerned about our safety and well-being. That's why we're formally documenting this incident and filing a complaint with the CSLB. If you're in charge, take a hard look at your staff and practices. They're harming your business and putting customers in unacceptable situations. Get in touch with us immediately before things escalate further.

I hired this AC and Heating crew from start to finish and was thoroughly impressed. They showed up on time, were dressed professionally, and had a good grasp of their work. They took the time to walk me through my system's issues and gave me clear choices for what to do next.
What struck me most was how courteous and respectful they were - they made an effort to be friendly and kept everything tidy while working. You'd hardly notice anything had been done by the time they left.
Finding a reliable, trustworthy team like this one is rare, but these guys did it right. I'd recommend them wholeheartedly to anyone in need of HVAC services.

Luis fixed the heating system well, doing a good job.

Precision heating and cooling deliver top-notch customer service, completing scheduled AC repairs and replacements promptly. Their techs are trustworthy, professional, and reliable.
