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.

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.
Cindy Marota

Timely updates from Marian
Company forgot to put a label on the equipment during installation. I followed up with the marketing person several times but didn't get any response from him. Later, I got connected with Hyman Kang and he was able to get the technician to install the label within a few days. He provided timely updates, which was recommendable.
Riddhi Khinvasara
Thrilled with A1's quality and pricing
As a property manager, I am thrilled with A1's quality and pricing. I not only use them for the investment properties that I manage, but I have also used them in my personal home. Marian contacted me immediately when my most recent proposal was sent to ensure I received it and asked if I had questions. Great customer support!

Highly Recommend Francisco Ramirez
Francisco Ramirez was my technician this morning, who, by the way, was very prompt on timing and presented himself in a very professional manner. He was very efficient and diagnosed the issue within 30 minutes of his arrival. I explained my concerns and described the problem as well as I could, and he thanked me and proceeded to work. I highly recommend Francisco Ramirez from A-1 Heating and A/C and would recommend his skills regardless of who he works for.
Stephen Fisher
An Overall Great Experience
Danny with A1 Heating and Cooling was our technician and was very helpful in giving us thorough explanations on what was needed, quick service, and an overall great experience!
Hugo Loya
Francisco was great
Had a quick "tune up" visit for our furnace. Francisco was great—called about 20 minutes before arriving, on time, tidy, polite, and communicated clearly. He ended up having to cut a filter to properly fit, and offered to come back at a later date to install a better cover (our filter had been taped over instead of a proper metal covering).

Deciding to repair or replace depends on the heater's age, repair cost, and efficiency. If repairs exceed half the cost of a new unit and your system is over 10 years old, replacement might be more cost-effective.
How much does heating repair typically cost?
Heating repair costs vary based on the issue's complexity, system type, and necessary parts. We provide upfront estimates to ensure transparency and will discuss repair options and costs with you before proceeding.
What should I do before calling for repair?
Before calling for repair, check your thermostat settings, ensure power switches are on, and replace dirty filters. If these checks don't resolve the issue, contact a professional for a thorough assessment.
Why is my heating system making noise?
Heating systems can make noise due to loose parts, debris, or mechanical issues within the unit. A qualified technician can diagnose the cause of the noise and perform necessary repairs to restore quiet operation.
