Same day service on a hot day is the best kind of help a man can ask for! They were fast and efficient. First place wanted to charge me a fortune for a new system; this was parts and maintenance (clogged air filter and blown capacitor). Highly recommend for a fair and honest deal!

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!

February 12, 2026 reached out to 20th century air Inc. for our annual heating and AC unit maintenance. Spoke to Julie and she was able to schedule me for our next day maintenance. She provided excellent customer service over the phone. Thank you, Julie.
Daniel was our technician who came to our home, I smiled when he pulled out a pair of fluorescent orange shoe covers. I loved it.!!!! Great idea, he explained to us what he was going to be doing and would keep us updated on every step of his process which he did. He provided us also with a free filter and let us know everything was running great very impressed with our maintenance that we stay on top of with our heating and AC. Daniel provided us with excellent customer service. He went the extra mile. We were very well taken care of and if we had any questions or concerns, he informed us that our heating system and AC system were working great and were in great shape. Thank you again Daniel for the excellent customer service. Keep up the great work that you’re doing.

Thank you 20th Century Air! My new AC works great. The crew showed up on time and finished the job the same day. I would highly recommend Scott and his crew for your AC and heating needs

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!
