Air Conditioning Services
Report
When the temperature and humidity outdoors become more intense, you'll have to rely on your air conditioning unit indoors. And if that air conditioning unit is not functioning correctly, the whole family or work staff suffers. Early maintenance can prevent these issues from happening. Also, this will prevent any issues that you had before from becoming into a worse and expensive problem. Extend the life of your air conditioning units and lower your utility bill by having a maintenance plan. Tune-ups every year or every spring can drastically help and helps with avoiding dust build-up which can cause your system to fail sooner and run harder than it should.
Heating Repairs
Report
Heating breakdown in the middle of a cold season is a pain for homeowners and businesses. If your heating system should break down or stop working, it is important to trust a company that is able to perform heating repair services quickly, affordably, and reliably. Without any maintenance, a heating unit can malfunction. A thermostat breaking down produces no heat and problems with the fan.

Without the components inside the heating unit working properly, air flow could be a problem, coming from unmaintained fan motors and belts and bearing. This issue can cause poor heating control and the furnace to overheat. With the help of our technicians, we are able to rid of these problems for you. If you are looking for routine maintenance or a major heating repair, California Air can help! Problems like carbon monoxide leaks are detrimental to anyone's health. Let us help you avoid this and keep you safe and comfortable.

My service call was excellent in terms of quality, price, and timeliness. He was amazing and knowledgeable in his explanations. Like all the ones before him who have done work at our home, the service man was professional, courteous and helpful. Let's also include the ladies who I talk to on the phone in that description.

Thoroughly great service fixing our heater. I had the pleasure of finding this company on the coldest day. I contacted them and someone was at my house the same day, within an hour! They were professional, kind, and attentive to my concerns. The technician stayed to make sure my issue was fixed and didn't try to up charged me for any additional service.

I was so happy to find a company that repairs swamp coolers! I'm especially pleased with the responsiveness and honesty of their operations manager, Harry who represented his business very well. He went above and beyond in explaining what could cause problems with swamp coolers, even told me what parts I may need to have it fixed. He made it clear that they want to take care of people and said he'd be happy to stop by when I was ready to have him take a look and added there was no pressure to do it.

Most companies are pushy. I told him I couldn't afford the repair this minute but he said not to worry about it no pressure and call him when I'm ready. rdy. He had offered to Stop by and give me an idea of what I'm looking at. There would be no charge to come out. Really, I am so impressed and would be happy to recommend them based on their attentiveness and honesty alone!

We are under the remodeling project. Looking for a company to replace the whole HVAC system in our house. We scheduled the visual estimate with California Air Conditioning Systems for Friday, February 25th. The technician didn't show up on time, the office didn't communicate with us as well. When we reach the company, they rescheduled the estimate to the following Monday, February 28. Anyway, the technician didn't show up again and the company didn't communicate with us AGAIN. So I have BIG questions not only about the customer service but about the workmanship. Do not waste your time on a company that can't keep its promises.

Great installation service! First time calling the team and couldn't be more pleased. Came in promptly, did the job, explained everything I needed to know, and hauled away the mess. The technician, was friendly and explained the checks on my AC unit. Service was great, everything was explained to me in terms I could understand and all my questions were answered.

I'm disappointed about this service, I had a visit from one supposedly technician to make maintenance to my AC and Heather in my house, and this guy didn't do it because supposedly my Heather wasn't working properly. ( I never had any problems with my AC and heather before in 16 years living here ) So when he arrived to my house the AC were working nicely set at 76 degrees and he shut it down and turn on the Heather and apparently not working at all and he just left, without turn on the AC back again. JUST LIKE THAT! So, when I tried to turn on the AC I couldn't and I had to call another technician from another company to come my house to fix it. So, I had to pay money for no reason. So disappointed!

Absolutely rude phone service! I called to ask if they sell and AC unit and the response could have been an easy no! instead she decided to get attitude for no reason. Called to get her name and she claimed it was Ceclia but she was upset that i asked that too so who knows. Bad day at work?

Harry was awesome! He was so quick to respond, and came out on a Sunday during the time frame he provided. He took pictures of what was wrong and gave me a detailed report of what needed to be done. Harry has a great personality, very professional and is a master at his craft. I will recommend him to all my family and friends. We were extremely satisfied with his service!

We had a fantastic time with them. After two months after purchasing our home, our system crashed. We phoned to schedule an estimate for a new system, and when the team arrived, they explained all of our options and assisted us in selecting the best system.

I've used California Air Conditioning Systems twice at my restaurant this past month. They cleaned up and figured out everything to do with my exhaust fan, hasn't ran this smooth since it was brand new. Great price on that and excellent customer service. We used them again this morning to service and clean up the AC unit. again they went above and beyond with the quality of their service and my AC is now blowing strong and clean smelling fresh air. Harry and his team are great and come highly recommended!

I have never seen a lack of customer service at a company in my 30 years on this earth. Asked a simple question to Sima and they were so rude. I can't see how they are in business with such a horrible, rude person working there. Please stay away and go to literally any other place in California.

Harry and his team were amazing, professional, thorough and did an outstanding job. I had a floor furnace (decades old) that had to be removed and replaced. It required a ton of difficult, physical work and Harry's team worked hard, efficiently and explained everything to me. I would recommend them to everyone. Don't even look elsewhere. Call these guys.

The quality of the heating/ac services this company provide is amazing! What they do is by the books and honest. They let you know what can't be done and gives you an alternative. They may not be the cheapest but they are the most correct.
Killian H Collins
These guys are great. They answered the phone on a Saturday evening, and our broken A/C unit was fixed in less than 24 hrs.
Harry was the guy who came out to fix our system, and he could not have been a nicer guy. I recommend them without any reservations!
Tara Bowie
Above and Beyond! The tech worked systematically through the problem, saved us hundreds and had us up and running in 2 hours at a rate that was amazing! Highly recommend! Thank you Harry and team.
Bridgette De Gyarfas
Harry and his team are AMAZING! We called California Air Conditioning Systems to help us solve a problem with air not getting to an entire side of the house. Harry came up with a plan and executed it beautifully. His team that came out were extremely professional and polite and were in and out with no hassle or fuss. They put down runners to protect my floor and cleaned up after themselves - it was like they were never there . . . except that now we had air conditioning! I highly recommend California Air Conditioning!
Lisa Marie
Recently, I had my air conditioning repaired and I was fortunate enough to have Harry, himself come to fix it personally. I really enjoyed hearing about their family business. They are a very honest and reputable company. They normally do commercial jobs but they didn't make me feel unimportant because I had a small residential job. Great customer service and reliability. No reason to call anyone else, you will be in good hands with CA Air Conditioning Systems. Oh and by the way my AC works great!!
Cassius Martin
I tried getting someone to come out to give me an estimate to fix my ac but most companies were busy. This company told me they had their technician near my area so they set me up with an appointment with him. It took a few days to finish because parts had to be ordered. The service they provided was very professional; clean and correct.
Suzie
I looked around for weeks and truly spent time researching companies and prices before choosing this company. Working with Harry and the rest of the staff was a wonderful experience. They were extremely professional and thoughtful. They did a thorough job replacing my heating system and cleaning it out to improve the air quality in our home, especially since my kids have asthma. I will be calling Harry for annual maintenance. Thanks to the team at California Air Conditioning Systems, Inc.
Alex Tracey
Harry came out to us on a Sunday within an hour of calling and fixed us right up. He put in the extra effort to make sure our system was clean and running efficiently, we will definitely be calling him out for yearly preventative maintenance for the force able future. Great experience and now our house is livable again, thanks so much!

Harry came out on a Saturday to take a look at our heater. It only took him a few min to figure out what was wrong. He gave us a great deal and is very professional and has excellent customer service! I would highly recommend this company!
