AC Installation in Santa Ana, CA

Why Homeowners Choose 20th Century Air For New AC Systems

Choosing a contractor for a new AC system is a big decision, especially when you are comparing several quotes. At 20th Century Air, we work to make that choice easier by focusing on honesty, quality, and long-term relationships with our customers. Our family has been in this business since 1987, and that history shapes how we handle every installation and replacement job.

Customers often tell us they appreciate that we do not rush to recommend a new system when a repair still makes sense. For example, a customer noted that our owner, Scott, carefully repaired an older unit instead of pushing a replacement that was not necessary at the time. That kind of no-pressure approach is at the core of how we operate. We look at the condition of your current system, talk through options, and help you decide what fits your home and budget best.

We also know that you want proof, not just promises. Many of those reviews highlight fair and competitive pricing, especially on full system replacements where customers received multiple bids. We are proud to be recognized as a leading installer of new heating and cooling systems in Orange County, and we work every day to live up to that reputation.

What To Expect From Your AC Installation Or Replacement

When you decide to install a new AC system, understanding the process helps the day go smoothly. We start by confirming your selected equipment, reviewing access to the work areas, and answering any last questions you may have. On installation day, our technicians arrive on time, introduce themselves, and take steps to protect your home, including using shoe covers and floor protection where needed.

Removal of the old system typically comes first. This includes safely handling any refrigerant according to regulations, taking out the existing indoor and outdoor units, and preparing the space for the new equipment. Our team then installs the new components, connects refrigeration lines and electrical, and makes any necessary adjustments to the duct connections. We use state-of-the-art tools and follow manufacturer guidelines so the system can operate as it was designed.

Efficiency and coordination are important to our customers, especially in warm weather. We have completed full AC and ductwork replacements in a single day on projects where other companies expected two days of work. That level of efficiency depends on the size of the home and scope of the project, and we plan the schedule based on what will allow us to do the job correctly. Before we leave, we test the system, check airflow and temperatures, and walk you through the thermostat settings and basic maintenance steps.

Long-Term Support & Maintenance For Your New AC

A quality installation is the first step, but regular maintenance helps keep your new AC running at its best. Over time, dust buildup, dirty filters, and normal wear can reduce efficiency and make the system work harder than it should. Routine tune ups give our technicians a chance to clean key components, check electrical connections, and spot small issues before they grow into larger problems.

Club Maintenance Membership Benefits

To make ongoing care easier, we offer a Club Maintenance Membership for our customers. Members receive priority scheduling, along with discounts on repairs, system replacements, and indoor air quality services. For many homeowners, this program offers both savings and peace of mind, since it sets a clear schedule for keeping the system in good condition.

Support For Homes & Businesses

We also support business and commercial clients with maintenance plans that match their operating hours and building needs. For typical office buildings, we may recommend several visits per year. For facilities with heavier demands, more frequent service can make sense. Whether we installed your system or you came to us later, our team is prepared to handle maintenance, troubleshooting, and additional upgrades as your property needs change.
