Bill Corkery
Overall really good experience
Just had a new furnace installed. Working with A1 HVAC couldn’t have been smoother from start to finish. Upon submitting my issue with Home Depot, I got a text from Bill saying he can help. He came over to my place, diagnosed the issue, and gave me a really fair quote. Three days later, a crew showed up early in the morning and installed the new furnace by early afternoon. Overall really good experience and I’d definitely recommend going with A1!

Supervisor and workers are very courteous and professional.
I bought a unit from these guys 4 years ago. I needed some help with the unit that is still under warranty. They came the second day; the first day they were busy. But the second day they came and took care of the problem. Supervisor and workers are very courteous and professional.

Hyman at A-1 H&C was exceptional!
Hyman at A-1 H&C was exceptional! I reported the AC problem on Sunday. Their office was closed, but he called me back within the hour and set up an appointment with a tech for Monday. Hyman arrived at our home on Monday before the tech to check out the problem and called the tech to inform him what needed to be done. The tech arrived on time and was friendly and proficient in diagnosing and repairing the problem—capacitor needed to be replaced. The downside of the experience was the cost. I was charged 40x the cost of the capacitor. I later priced it at HD for $18!

Had such a great, easy experience with this company. From Hyman in sales, to Evuardo and Mel for install, and Francisco as a tech (and all the other team members who accompany them—I forget everyone’s name!) it was a great experience for a brand new install. Thanks A-1! Highly recommend.
McKenzie White
Fixed the issue at lightning speed
I had an issue with the AC unit which was not cooling. I called them and service person Porter showed and fixed the issue at lightning speed. He knew what was wrong the moment he saw the unit and he was spot on with the diagnosis. I would highly recommend Porter and A1 Heating for their best service.
Vamsi Krishna
Very responsive in scheduling the appointment.
A-1 was very responsive in scheduling the appointment. Technician arrived on time and made a thorough evaluation of AC and furnace. We have very old systems, so it was good to get cost of repair vs. replacement vs. heat pump options.
Rajeev Bajaj
He was a great salesman and I think I will buy.
I had P. Tanner to my home today. He was giving me information about a sump pump. He was a great salesman, and I think I will buy. My furnace costs $359–$525 to run monthly.

Great help with A/C repair
Marian at A1 Heating and Cooling was great at helping me to arrange for my A/C repair, especially when I had multiple problems with the parts department. Technician Francisco was professional and explained the immediate work and future work requirements really well. I am looking forward to working with them on upcoming work and hope to have better luck with the parts department next time.
Sam Park
Francisco is a top-notch technician.
We noticed a leak coming from under the heat pump and needed a prompt response. Francisco arrived right on time and conducted a thorough inspection of the unit and clearly explained what was causing the issue. He walked us through our repair options without any pressure, making sure we understood everything before moving forward. What really stood out was how knowledgeable and informative he was—he offered helpful tips for maintaining our unit to help prevent future problems. He worked efficiently and with great attention to detail, and when he was done, he left the area spotless. We are genuinely impressed by the high level of service that A1 Heating and Cooling provided. Francisco is a top-notch technician. Highly recommend!

Highly Recommend A1 Heating & Cooling
A1 Heating & Cooling installed my heat pump system with HVAC upgrade. The team was very professional, efficient, and helpful. The cost was reasonable for California/Bay Area. Not all HVAC technicians can work on these new systems, but A1HC has some of the best people so far. I would highly recommend you give them a call for a no-pressure price quote.
Sean P.
Helpful in Scheduling Appointment
Marian was very helpful in getting my appointment scheduled. She checked the warranty on my AC unit and answered my questions.
Amogh Simha
Excellent Experience with A-1
My experience with A-1 Heating & Cooling was excellent starting from my first contact with Desiree to the final installation of 2 new air conditioners. Desiree graciously worked to schedule an appointment that met our needs. During my consultation with Danny and Warren to assess potential to repair an old air conditioner, they took their time to evaluate the unit all the while explaining their findings. Danny and Warren did not at any time push to purchase a new unit. After talking with them we decided to purchase 2 new air conditioners (this is for a four-plex). Both installations went seamlessly thanks to the knowledgeable and amazing work of our technicians Alberto Morales and Evevdavdo Mel. They were very patient when I struggled to answer some of their questions and continued to talk with me until all was resolved. They worked diligently and were very respectful of the property and residents. Alberto and Evevdavdo cleaned up very neatly following the end of each installation. When it comes time to replace the other 2 air conditioners we will be using A-1 for sure; and hopefully Alberto and Evevdavdo will be our installers. Thank you A-1 Heating & Cooling.
