HVAC reviews in Anaheim, California

We had an issue with our heater not working, made a call to Ryan Hall who was very professional and friendly. Thankfully they were able to get to us same day and get our heater working! Needless to say, the wife and kids are happy we don’t have to wear jackets inside now!

Thanks again Ryan

These guys are very knowledgeable and efficient with their work. They gave us options that fits our budget. New AC and ducts within 8 hours or less. Also took care of our old unit. Highly recommended. Two thumbs up

Daniel Pop is the man. He explained everything I need to know about the AC with his honest opinion. Very polite and fun to talk to. I will highly recommend this place if you want to get the job done right. He knows his stuff.

I am so glad I called 20th century! I was calling them to get a second opinion on needing a new whole air conditioning system. Juan was only here for 20 min and fixed the problem by changing some fuses. I am laying in my room with cold air blowing on me and so happy! We have been suffering for a month. He saved me $10,000 plus! He says he is a repair man and not a sales man! Thank you 20th Century and Juan!

My AC went out a month after I had another company come out to fix it. Decided to give someone else a shot. I decided to give 20th a call and they showed up about an hour after I called. Got right up on the roof, diagnosed the issue, and had me up and running quickly. He even took the time to explain how the system works and what to look for in the future. Can't recommend this company enough! They'll be my first call if I ever have HVAC problems in the future.

We had a great experience with 20th Century Air. Our technician Daniel Pop was very thorough and explained everything he did and our options. I will definitely use them again and recommend them to anyone.

Engaged 20th Century Air to perform our annual maintenance for both systems. Daniel was the technician who came out and he was exceptional in reviewing in advance what was to be performed. In fact this was his 2nd time to our home since on the initial visit it was not hot enough outside to actually do the diagnostic testing. So appreciated that Chris and Julie in their office were able to reschedule and "watch the weather" to schedule at the perfect time! Indeed, 20th Century underscores what it means to be "customer service focused and client responsive." Hats off to all the team members who execute at such a high level, especially during these times where companies pay more lip service rather than actually being "client-centric," and 20th Century Air actually delivers!...

Just moved to a new place and wanted 20th Century was recommended to me for heating and AC maintenance. I wanted to have the system tuned to before the summer heat hit, so I opted for their annual maintenance plan. Daniel showed up and immediately got to work. He gave the AC system a good tune up and is running much quieter now. Daniel was extremely knowledgeable and not pushy about upselling. He coached me on my system and gave good recommendations to keep the system healthy. Definitely made the right choice with 20th Century and look forward to having them out for a winter tune up.

Our A/C went out during the triple digit heatwave. They were able to come out the same day! They communicated the problem well and got our air back up and running. They also made some adjustments to cool the house better. They replaced our filter for free and you cannot beat the price. They were honest and didn’t try to upsell us on any parts or service we didn’t need. Highly recommend 20th century!!

The sales men that meet you to discuss a system with you are often times the technicians that work on these systems, so they know what they’re talking about. They work very closely with the installation teams.
I purchased one of the new HVAC systems that was multi zoned using one main compressor unit where each room in the house was controlled by its own thermostat (not a mini split system). This system was highly technical and required technicians working along side installers for two days to complete the installation. The 20th Century Air team showed up on time, and exhibited the epitome of teamwork to complete this difficult installation. All the while, Julie, back at the main office kept in touch with me to make sure I was informed and to schedule my training with the technician, Ryan Hall. Ryan is very knowledgeable of this system and explains the ins and outs of how to use this complex system in plain simple to understand terms. We love working with 20th Century Air. They are not the cheapest on the block, but in this instance, you truly get what you pay for and there is true value in what you do pay. I have never regretted my decision.

I have been using 20th Century Air for the last few years to help service my A/C system. Each time they are always so helpful and willing to come at short notice. Last year, during a pretty hardcore heatwave, our condenser went out and they were so quick to help resolve our issues and were able to get us back into cool air super quickly. From efficiently scheduling our appointments to fantastic service, 20th Century is great all around.

We were thinking about getting a multi zone mini split AC system installed before the summer so we reached out to a few companies and Ryan from 20th Century Air came to our house for a thorough estimate within a day or two. We received the pricing within a few hours and it was very competitive so we ended up going with 20th Century Air over a few competing bids.

We scheduled the installation for the next week and Robert, the point person for the job, and his crew completed the 4-zone system installation in less than two days. The installation looks very clean and the indoor heads are less obtrusive than I thought they would be. 20th Century Air also handled the permitting process and they were careful to ensure that the work is up to code for our city (Long Beach).

The mini split system has been working great and just passed inspection by the city with no issues so we couldn't be happier with our experience with 20th Century Air!

20th Century Air was responsive to texts and calls, and very professional. Both Julie and Chris responded quickly to my texts and voicemails. Daniel came out and very helpful. When the repairs I paid for did not fix my problem, he came back and did additional repairs for free. I would call them again for future heating and air repairs. Thank you!

20th Century Air is very good company and very professional. We email them at 6 pm request for add Freon AC , they response very quick and set appointment for next day. They gave us the breakdown of service fee and how much estimate cost . The technician, Juan that come to check our AC and found out only the breaker is off and don’t need Freon charging. He is very honest , professional, knowledgeable and friendly .
Thanks to Juan that performed a fantastic work and also to all staff of 20th Century that doing a good service . We will use 20th Century Air again for our needed in the future . We highly recommend 20th Century Air to everybody .

EXCELLENT - I shopped around for awhile to replace my HVAC and ducting. Got various bids. My neighbor introduced 20th Century Air to me who installed new system for him last year. He told me he also shopped around and got the best prices with superb job. They were so professional and knowledgeable and best price ever. I am referring so many of my friends and am getting the message across to everyone. PLEASE call them and they work with you on the price with great job.

We have been with 20th Century Air for over 10 years. They are trustworthy, punctual and professional in their service. We really like working with Ryan who maintains our home and rental AC/ heating systems. We also really appreciate Julie, the office manager, for all of her help and kindness.

These guys are on top of their specialties. We been their clients for almost 3 years now. Honest dependable and flexible. That goes pretty much on prices as well as availability. Our central AC wasn’t blowing as cold as it should. One of their tech, Juan, who’s been servicing and doing the yearly tune ups and maintenance for the last 3 years diagnosed it with their equipments and tools and found that our freon was low (under 2lbs) He showed me all the numbers on the high tech equipment and told me that since because of the square footage of the house it will take at least 5-7lbs of Freon to be comfortable. The last time we add Freon was 4-5 years ago so it was due. We currently has a 10 year old central AC. We decide to do the service and he brought the tanks and showed me the new numbers on their machine as soon as it was done. It was on 2lbs and after the fill it went up to 6.5lbs and went inside to check the air it was freezing like the North Pole on every single room in the house all the way to the 2nd story rooms. In the end he even still gave us a 10% discount and he did the outside condenser cleaning for free. I recommend these guys for all your maintenance and service needs. Summer heat are inevitable it will come. I highly advise anyone to call and make schedule before the heat gets here because usually when the heat is on they will be busy and you might have to wait a week for them to stop by. Whole week with no AC or not so cold air in a 100 degrees weather is a nightmare. Cheers 🍻

Daniel at 20th Century Air was amazing!
I had water coming out of my outside line, and he was able to diagnose the issue, and clear the P-trap.
My appointments are easy to make and I always get a call back within 5 minutes of contacting them.
I will continue to use 20th Century Air for all of my HVAC needs.
Thank you Daniel for your great service!
Also thank you Julie for your kindness and support at the office and answering all of my questions.
Ten out of ten stars for you both!

Chris and Daniel get you what you need, and more! We needed to retrofit an old central heating system to also cool. Chris was quick to provide availability the very next day and Daniel arrived on time with everything we needed to know to make the best decision for us. You can tell that everyone here knows their role and the industry very well.

Look no further if you are looking for a company that believes in their work, their products, and works together as a team to get the job done. The traditional hassles of getting quotes, scheduling, installation, and worrying about whether or not you can trust that you got the best value are gone when you work with 20th Century!

Living in Orange County California, a reliable AC unit is a must-have, and let me tell you, mine was 37 years old and it was time to be replaced. Thankfully, 20th Century Air was referred to me by a good friend of mine! From the get-go, they impressed me. They were super responsive when I called, scheduling an appointment quickly to assess the situation. The manager, Daniel Pop, was fantastic. They arrived on time, were professional and friendly, and most importantly, knowledgeable.Daniel checked my house and gave me a very competitive price quote,  He presented different options for replacing the AC, helping me choose the perfect fit for both my needs and budget. There was absolutely no pressure to upsell anything, which I truly appreciated.The installation itself was a breeze. The crew worked efficiently, cleaned up thoroughly afterwards, and even took the time to show me the ropes of the new system and answer any questions I had.Overall, I couldn't be happier with the entire experience.  20th Century Air is a top-tier company with fantastic customer service and highly skilled technicians. My home is nice and cool, and I owe it all to them. If you're in Orange County, California and need AC work done, look no further than 20th Century Air! You won't regret it.
