How Long Will My HVAC System Last In California?
The lifespan of an HVAC system can differ greatly depending on a variety of factors. In the field, the typical life expectancy we see is approximately 16–20 years. Despite this, there are plenty of exceptions. We’ve come across outdoor condensing units that have lasted over 30 years, and furnaces that still run after 40 years.
The truth is, nobody can say with certainty how long your system will last. Once you reach the 20-year mark (or even close to it), your HVAC system has done its job. One thing worth noting is that many older systems seem to outlast the ones being manufactured today. A big reason for this shift is the industry-wide transition away from copper coils to aluminum coils, primarily to cut costs.
Factors That Impact HVAC Lifespan
Location of your system – Direct sun exposure, heavy dust, or proximity to the ocean is also a common factor. For homeowners in Southern Orange County especially, salt exposure can greatly reduce lifespan.
Proper installation – Even the best equipment won’t last long if it’s not installed correctly.
Usage – Heavy demand on the system wears components faster.
Maintenance – Keeping condenser coils clean and changing air filters regularly is crucial.
System size – An undersized or oversized unit strains core components, reducing longevity.
Brand and build quality – Systems built with copper coils almost always outlast those with aluminum.
How Long Can I Expect a New HVAC System to Last?
Once again, it depends on the factors above. Based on our installations across Mission Viejo, Lake Forest, and the surrounding Orange County area, most high-quality systems last 15–20 years.
It’s also important to pay attention to warranties, since they often reveal how confident a manufacturer is in their product. For example, condensing unit compressor warranties can range anywhere from 3 to 10 years, even when the price tag is similar. This is why comparing coil materials (copper vs. aluminum) and warranty coverage can make a big difference when choosing a system.
In our experience, we’ve had excellent results with brands like INNOVAIR, YORK, and ACPRO. These manufacturers consistently offer copper coil systems, strong warranty programs, reliable customer support, and competitive pricing.
