HVAC Installation in Anaheim
Full System Installs & Replacements From a Family-Owned Company Since 1987
20th Century Air has been installing and replacing HVAC systems in Anaheim and across Southern California since 1987. We cover the full range: central air conditioning, gas furnaces, heat pumps, ductless mini-splits, and duct installation. Whether you’re replacing a system that’s reached the end of its life or installing in a new construction, we bring over 38 years of hands-on experience to every project.
We serve homeowners, contractors, HOAs, office buildings, and retail establishments throughout Orange, Los Angeles, and Riverside Counties. Our approach hasn’t changed since day one: honest assessments, upfront pricing, and no pressure to buy something you don’t need. Owner Scott has been known to repair an older unit when repair is the right call rather than push for a replacement.

Why Anaheim Homeowners & Businesses Choose Us for HVAC Replacement
We provide free estimates on every installation and replacement project, with upfront pricing and no hidden costs. Customers who collect multiple quotes for full system replacements consistently find ours to be competitive. That’s not an accident: our referral-driven business model keeps overhead low, and we pass those savings along.
Pricing & Financing
Affordable payment plans and financing are available through our partnership with Service Finance, making a full HVAC replacement more accessible even when the timing isn’t ideal.
Speed Without Shortcuts
Our licensed and insured technicians have completed full AC and duct replacements in a single day, a job other companies estimated at two days. We don’t cut corners, and we don’t leave a job half-finished.
Club Maintenance Membership
Members receive 5% off system replacements, 10% off repairs, 5% off indoor air quality services, and priority scheduling. It’s designed to help lower your long-term cost of ownership from the moment installation is complete.
A+ BBB Rating & All Makes and Models

What Anaheim Customers Say About Our HVAC Installations
20th Century Air has earned 378 reviews on Yelp with consistently positive feedback, alongside an A+ rating with the Better Business Bureau. The patterns across those reviews are specific: technicians show up on time, complete the work at the quoted price, and don’t use a service call as an opportunity to sell something unnecessary. For large installations, reviewers note that our team treated their homes with care throughout the job.
That track record reflects what we’ve built over 38 years in Southern California: show up, do the work, charge what we quoted.
