1 month agoWhen 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. -

5 months agoSame 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! -

6 months agoDaniel 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! -

FAQ
How does 20th Century Heating and Air determine pricing for HVAC work?
We provide upfront pricing based on a thorough evaluation of your system and the scope of work needed. Our estimates include equipment specifications, labor costs, permits if applicable, and any additional materials or services. We recommend getting multiple quotes to compare, and we're happy to walk you through what's included in our estimate so there are no surprises when the work is complete.
Are you licensed and insured to perform HVAC work?
20th Century Heating and Air maintains the proper licensing and insurance required to serve Anaheim homeowners safely and legally. Our certified technicians are trained to handle HVAC repair, installation, and maintenance according to industry standards. You can ask for proof of our credentials and insurance coverage when we provide your estimate.
Does 20th Century Heating and Air handle both furnace and air conditioning installation?
Yes, we handle complete HVAC installation for both heating and cooling systems. Our work includes proper equipment sizing through load calculations, ductwork evaluation, line set installation, refrigerant charging, thermostat setup, and system testing. Whether you need a new furnace, AC unit, or both, our team ensures everything is installed to manufacturer specifications for optimal performance and efficiency.
How quickly can you schedule service when my HVAC system fails?
20th Century Heating and Air offers same-day emergency service to get your system running again when you need it most. We understand that heating and cooling emergencies can't wait, especially during extreme weather. Contact us as soon as you notice a problem, and we'll work to get a technician to your home quickly to diagnose and repair the issue.
What does 20th Century Heating and Air do with debris and how is my home left after installation?
We treat your home with respect throughout the installation process. Our team uses drop cloths and protective coverings to contain dust and debris, and we clean up thoroughly after the work is finished. We remove all old equipment and waste materials properly, leaving your home clean and ready for you to enjoy your new or repaired HVAC system.
Why should I hire a professional instead of attempting HVAC work myself?
HVAC systems are complex and require specialized knowledge, tools, and certifications to work safely and effectively. Improper installation or repair can reduce efficiency, void warranties, create safety hazards like refrigerant exposure, and lead to costly damage. Professional technicians conduct proper load calculations, inspect all components including ductwork and electrical connections, verify correct refrigerant charge, and test system performance to ensure everything operates as designed.
