We built 20th Century Air on a simple approach, treat every home as if it were our own and provide the same advice we would give a family member.

Our licensed and insured technicians arrive prepared, with state of the art tools and equipment, and they respect your home by using floor protection and shoe covers and cleaning up before they leave.

We are also recognized as a leading installer of new heaters in Orange County. That installation volume translates into practical knowledge about different brands, system types, and layouts.

Is It Time To Replace Your Heater

Deciding whether to repair or replace a heater is a big decision. You may be dealing with frequent breakdowns, uneven temperatures from room to room, or rising utility bills. We guide you through that choice by sharing what we see on site, explaining your options clearly, and not pushing replacement when a repair still makes sense.

Most central heating systems have an expected service life that depends on their design, how often they run, and how well they have been maintained. In Santa Ana, winters are milder than in colder regions, so heaters may run fewer hours each year. Even so, age, lack of maintenance, or poor installation can cause a system to lose efficiency or become unreliable well before it completely fails.

California also has energy efficiency standards under Title 24 of the California Code of Regulations. Older equipment may use much more energy than current models that meet today’s requirements. That difference can show up as higher gas or electric bills, especially in homes with poor ductwork or outdated controls.

Common signs it may be time to consider heater replacement Santa Ana homeowners should watch for include:

• Frequent repair calls or repeated issues with the same components
• Noticeable increase in energy bills without a change in usage
• Rooms that are consistently too hot or too cold compared to the rest of the home
• Unusual noises, odors, or visible rust and deterioration on the unit
• A system that is reaching or past typical age expectations and has no maintenance history

When we visit your home, our technicians inspect your existing heater, discuss your comfort concerns, and review any past problems. We then talk through realistic repair options and replacement choices, including efficiency levels and estimated operating costs. Our recommendations are based on what is sensible for your home and your budget, not on meeting a sales target.

Our Heating Installation Process

Knowing what to expect from a new heating installation can take a lot of stress out of the project. We have refined our process over many years of serving homes in this part of Orange County so that the work is organized, respectful of your schedule, and focused on quality from start to finish.

The process usually starts with a free in home estimate. One of our technicians visits your property, looks at the existing equipment and ductwork, and talks with you about any comfort problems. We consider factors such as home size, insulation, window exposure, and how you use each space. From there, we suggest equipment options that fit your needs and comply with California Title 24 energy efficiency requirements.

Once you choose a system and approve the estimate, we schedule the installation for a day that works for you. Our team arrives on time and explains the plan for the day before any work begins. We protect nearby floors and surfaces, safely remove the old equipment, and bring in the new system using tools designed to minimize disruption in your home.

Our licensed technicians handle all mechanical and electrical connections and make adjustments needed for proper airflow. We work to follow manufacturer instructions closely so that your new heater operates as it was designed. Because we perform many installations in Santa Ana and surrounding communities, we are familiar with local building departments such as the City of Santa Ana Planning & Building Agency and their typical inspection requirements.

In many homes, especially where ductwork is in good condition, we can complete a full system installation in a single day. Some larger projects or those involving significant duct changes can take longer, and we explain that clearly during the estimate. Before we leave, we test the system, walk you through basic operation and thermostat settings, and clean the work area so you are not left with a mess.

Throughout the process, our focus is on safe, reliable work and clear communication. We want you to feel comfortable asking questions at any stage, whether it is about how long something takes, why we are doing a particular step, or how best to use your new system.

Cost, Financing, & Long Term Value

Heating installation or replacement is a significant investment, and cost is usually one of the first questions homeowners have. We believe that pricing should be straightforward, so we provide detailed estimates that outline the equipment, materials, and labor included in your project. You see the full picture upfront before any work begins.

Many customers who obtain multiple quotes tell us that our prices are among the most competitive they receive. Our approach is to offer fair pricing and to avoid padding estimates with unnecessary extras. Much of our work comes from referrals and repeat customers, which helps us keep marketing costs low and pass that value on to homeowners.

We also know that even with fair pricing, a new heater can be a strain on a household budget. That is why we offer financing and affordable payment plans through our partnership with Service Finance. Financing can make it easier to move forward with a needed upgrade rather than putting up with an unreliable or unsafe system.

Energy efficiency is another part of the value equation. Modern heaters are designed to use less energy while providing consistent comfort, especially when paired with programmable or smart thermostats. In Southern California, improving efficiency can help reduce utility bills over time, particularly in homes where older equipment has been running far below current standards.

To protect your investment, we recommend ongoing maintenance after installation. Our club membership offers scheduled tune ups, priority service, and discounts on repairs and future system replacements. Regular maintenance helps keep your system running efficiently, identifies small issues before they grow, and supports better indoor air quality for your household.
