Picture this: you turn on the heat on a cold winter night, and… nothing happens. Your HVAC system has quitA toy home sits on top of a pile of money and papers next to a calculator, implying that someone is making home budget calculations. right when you need it most. We’ve all been there, and it’s never convenient. 

But why does this happen?

Maybe you’ve wondered why your HVAC system didn’t last as long as expected. Or more precisely, what factors determine how long it will keep running smoothly? Many homeowners just like you wonder the same thing: 

‘Why is my system not lasting as long as I expected?’ 

‘What could I have done to extend its life?’

At A&E Plumbing, Heating & Air, we bring over 16 years of experience working with HVAC systems across various conditions. We’ve seen firsthand what keeps systems running longer and how small changes can make a big difference in performance and durability.

In this article, we’ll break down what affects the lifespan of an HVAC system—and how you can make it last. 

Why Do HVAC Systems Stop Working?

Let’s start with a basic understanding: HVAC systems, like any machinery, wear out over time. They don’t break randomly—several key factors impact their lifespan, some of which are within your control.

While some systems last 20 years, others may give out in a decade.

So, what’s the difference? Let’s go through the major factors.

1. Quality of HVAC System Installation: Was It Done Right?

It might seem obvious, but how your HVAC system is installed has a big impact on its performance andAn A&E employee kneels on the ground to perform standard maintenance on an outdoor HVAC unit. longevity. Imagine investing in a high-quality vehicle only to have a key component installed improperly—it wouldn’t work to its full potential.

The same applies to HVAC systems. If the system isn’t installed correctly, you’re looking at issues from day one. An incorrectly installed system can result in leaky ducts, airflow issues, or even the wrong size system for your home. Trying to use an undersized HVAC system is like trying to heat your entire house with a hair dryer—doable, but barely.

Here’s a tip from our A&E team: always rely on a professional for installation. With over 16 years of experience, we know that quality installation is essential for a durable system. We also back our work with leading warranties and guarantees, so you’re not only getting expert service—you’re gaining peace of mind, knowing we’ve got you covered if any issues arise down the line.

2. Regular Maintenance: Keeping Your System in Shape

Just as regular oil changes keep a car running well, HVAC systems benefit from routine maintenance, including tune-ups, filter changes, and coil cleaning. Without it, parts wear out faster, and efficiency declines—costing you more in energy bills over time.

Routine maintenance doesn’t just prevent breakdowns; it also keeps the system running efficiently. Investing in regular care now means fewer interruptions, lower bills, and more dependable comfort for years to come.

3. Usage: Are You Overworking Your System?

How hard your system works also matters. If you’re constantly running it at full capacity, it’ll wear out faster. For instance, Oregon winters can be harsh, but setting your thermostat too high forces your HVAC system to work harder than necessary. Likewise, skipping thermostat programming for energy-saving settings can shorten its lifespan.

The key is balance. Program your thermostat for when you’re home versus away, and try not to overwork your system. Giving it a break now and then can make a big difference in its longevity.

4. Climate: How Oregon’s Weather Affects Your HVAC System

Running your system at full capacity around the clock can shorten its lifespan considerably. We understand—Oregon winters can be harsh, and turning up the thermostat is tempting. However, setting it too high or skipping thermostat programming can lead to high utility bills. It’s like leaving your lights on all day: wasteful, expensive, and unnecessary.

Program your smart thermostat for times when you’re home versus away, giving your system a rest when possible. Like all of us, your HVAC system benefits from a little downtime.

Best HVAC Systems for Extreme Weather

Oregon’s weather can be all over the place, so you need an HVAC system that can handle it. Systems likeA heat pump sits on the outside of a home, snow on the ground around it and on top of the unit itself. the Trane XV20i and Carrier Infinity 24 Heat Pump are built for durability and efficiency in tough or extreme climates, thanks to their variable-speed compressors that adjust to your home’s needs.

During those frigid winters, Mitsubishi Electric’s Hyper-Heating H2i excels, maintaining warmth even at -13°F. These systems are not only reliable but also built for longevity, ensuring you stay comfortable without being left in the cold or overheating.

If your system’s struggling with Oregon’s wild temperature swings, it might be time for an upgrade.

5. The Type of System: Different Systems, Different Lifespans

Not all HVAC systems are built to the same standard, and the type of system you choose can significantly impact its lifespan. For example, heat pumps typically last around 10-15 years, while a well-maintained furnace can last up to 20 years.

Quality is essential in HVAC systems. 

Choosing a low-cost option may save you some money initially, but it often leads to shorter system life and more frequent repairs. Investing in a higher-quality model can ensure better durability and performance, especially when facing Oregon’s demanding weather.
