As a homeowner, it’s important to understand your HVAC system’s lifespan so you can plan for replacement costs and timeline. Over time, heating and cooling systems naturally wear out from mechanical friction, thermal stress, and component degradation.
Curious how long the average HVAC system lasts? We’re going to discuss HVAC system lifespan and how to tell if your HVAC is nearing the end of its life in Silverdale, WA.
What Is the Average Lifespan of HVAC Systems?
The average lifespan of an HVAC system depends on the type of system and whether it receives regular maintenance.
- Central air conditioners typically last 15 to 20 years, with some lasting up to 25 years.
- Gas furnaces generally last 15 to 20 years with proper care.
- Typically, electric furnaces last 20 to 30 years with routine maintenance.
- Heat pumps often only last 10 to 15 years but may last up to 20 years with exceptional care.
- Ductless mini-split systems typically last 10 to 15 years, with premium options lasting up to 20 years.
What Factors Affect HVAC Lifespan?
There are several factors that commonly impact the lifespan of an HVAC system, including routine maintenance, usage and demand, local climate, and installation quality.
Routine Maintenance
Regular maintenance is essential to extending the lifespan of your HVAC system. Without regular maintenance, your system may experience increased strain, premature failure, and costly repairs. An HVAC system should be professionally inspected and serviced twice a year (fall and spring tune-ups).
Usage and Demand
How heavily an HVAC system is used also affects its lifespan. Heavy usage directly accelerates wear and tear on your system. If you run your HVAC constantly, it forces the internal components to work harder than they should and shortens equipment lifespan.
Local Climate
Your local climate can also influence how long your AC unit or furnace lasts. Areas that require year-round usage will last a fewer number of years than in more temperate regions. Additionally, coastal areas with high humidity and moisture may see rust and corrosion issues that reduce system lifespan.
Installation Quality
Proper installation is critical to the lifespan of your HVAC. Installation should include proper load calculations, correct refrigerant levels, properly sealed ductwork, and accurate sizing. If an HVAC system is undersized or oversized, it can significantly impact its expected lifespan. Incorrect refrigerant charges can damage compressors and negatively affect system efficiency.
Signs Your HVAC System Is Near the End of Its Lifespan
If you’re unsure if your HVAC system has much life left in it, consider these common signs it’s time to replace the system soon:
- Frequent repairs: Aging HVAC systems generally require an increased number of repairs.
- Increasing energy bills: If your energy bills are steadily increasing for no apparent reason, your HVAC system may have lost efficiency.
- Uneven temperatures: Uneven temperatures throughout the house can signal that your HVAC system is struggling to keep up with heating or cooling demands.
- Strange noises: Banging, booming, or rattling noises are never a good sign and can indicate that there are issues with loose components or mechanical failures.
- Weak airflow: Often, older HVAC systems struggle with weak airflow due to wear and tear on the blower motor.
- Poor humidity control: HVAC systems remove excess moisture from the air before redistributing it into your home. Aging systems may not remove moisture effectively, resulting in higher humidity.
- Refrigerant leaks: Refrigerant leaks can occur in older HVAC systems when coils and lines become corroded.
- System cycles constantly: If your HVAC seems like it is constantly turning on and off, it can be a sign it is on its last leg.
- Difficulty maintaining thermostat settings: When HVAC systems fail to maintain the set temperature, it can be a sign they are rapidly losing efficiency.
When to Repair vs Replace Your HVAC System
Now that you know the warning signs, let’s discuss how to know whether to repair or replace your HVAC system.
You should repair your HVAC system if:
- Your HVAC is still under warranty
- It is under 10 years old
- The overall value is still high compared to repair costs
- The repair is limited to a single isolated component
You should replace your HVAC system if:
- It is over 10-12 years old (for most system types)
- Repair costs are substantial and surpass 50% of the cost of a new system
- There are multiple major components needing repair
- Parts are hard and expensive to source due to age of system
The professionals at Mercurio’s can assess your HVAC setup to determine whether you should replace it or simply make repairs. We provide honest recommendations, so you can make the smartest and most cost-effective decision.
How Can I Extend the Life of My HVAC System?
To extend the life of your air conditioning or heating system, the best things you can do are invest in annual maintenance (spring and fall tune-ups), address performance issues promptly, change your air filters regularly, and clear around the outdoor unit.
- Schedule annual maintenance: You should have your HVAC system service twice a year. Once for a spring tune-up and once for a fall tune-up.
- Address performance issues: Don’t wait to address performance issues. Catching and fixing issues early prevents them from escalating into major issues or permanent damage.
- Change air filters: Your air filters should be changed every 30 to 90 days depending on manufacturer's recommendations.
- Clean around outdoor units: Clearing debris and overgrown vegetation around outside units gives them proper ventilation and air flow.
