Mr. Harry Irvine inspected my Cozy wall furnace at 4 PM during a holiday weekend. He is extremely knowledgeable, professional, and honest.

He is a specialist for vintage Cozy and Williams wall furnaces. There is not an HVAC contractor in Los Angeles County, who is as knowledgeable as him. If you live in an apartment building and have an older wall furnace that needs maintenance, he is the only go to person. I only wish I found him sooner.

We purchased an air conditioner from California Air Conditioning Systems in 2020 and I’m pleased with unit. It needed repair in September 2024 and the repairs were done by them. I was told I would be billed for the repairs. The company had my name, address, phone number and email address.
I hadn’t received any bill for repairs that were completed in September but on December 11, 2024, I received a phone call from an angry staff woman claiming they were going to sue me and my tenant (where unit was installed and repaired) by Friday if I didn’t pay the outstanding bill.
I explained I hadn’t received a bill. She screamed bill was sent via email.
I asked her what email and she gave me the email that was on the unit purchase agreement from 2020. My email had changed 2 years ago (2022). I was never asked for email address when repairs were done in 2024, but she had my address and current phone number.
She could have called phone number when the email was rejected/kicked back and I would have gladly given her my current email address.
Meanwhile I agreed to pay bill as I knew it was owed and told her I hadn’t received any billing.
I was charged for repairs (fair) but she added late fees, interest and processing fees. She had some culpability in the mix up and never would admit her negligence.
I admit I should have called and asked where bill was as it was 3 months since service. Adding the late fees plus interest was vindictive and not called for.
Never should a customer be screamed at and threatened to be taken to court.
The air conditioner is great; no complaints but the customer service was surprisingly poor.
Thanks for allowing me to relate this incident. It was totally unnecessary and uncalled experience.

Harry didn’t actually fix my Williams wall heater, but I wished he did. It was clear from my first conversation with them that he was an expert in furnaces. Unfortunately, he was out of my service area, but he went to great lengths to help me diagnose my problem over the phone. I called him a few times while another HVAC technician was there, while he walk him through what to look for.

It was a great demonstration of his character and expertise in being willing to help with no financial gain. Harry is definitely the guy I would with if he served my area. Thanks Harry!

Good communicator, knowledgeable and trustworthy! Harry was able to come repair my AC on short notice and was very communicative via text to schedule the time and keeping me updated of his ETA.
My AC stopped producing cold air and Harry was able to thoroughly diagnose the problems and show them to me. I didn’t get any hint of an attempt to upsell me on anything so I felt I could trust that Harry was giving me an honest assessment of the problems. The service and parts replacement he did on my AC to restore it to functioning condition was fairly priced.

California Air Conditioning Systems are extremely professionals, this is our experience working with Harry and team, we are pleased to find a professional technician in AC, in the past we have been working with someone who only repair and do not maintain the unit in good shape, they just showed up to fix and leave right away, but this is my experience in the past.
Now we are using California Air Conditioning System for maintenance and repair our AC units,
Harry has the knowledge and he provided the best quality with pictures and videos , before and after complete his work.
Harry showed up on time, he clean the AC unit, duct, we can see and feel the difference before and after, now we have clean and cool air.
I highly recommend California Air Conditioning System, they are professionals, honest and punctual,

I highly recommend California Air Conditioning Systems! They are not only efficient, but also incredibly quick. Harry and his team ensured that we had our AC up and running the very next day. The team's professionalism and attention to detail were impressive, and they went above and beyond to make sure our AC was working. Thank you to Harry and his team—they are the best!
