When my AC failed over the weekend, I scheduled an appointment for Monday. Juan and Adrian arrived on time, diagnosed and replaced the failed contactor in the compressor. They tested the repair and texted a link for the very affordable online payment. I was very satisfied with service a highly recommend 20th Century Air for fair, honest, and affordable HVAC installation (they did the new install in 2018), annual service and maintenance.
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.
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!
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
