Typical Lifespan of HVAC Components

Typical Lifespan of HVAC Components

Your HVAC isn't just some of your home's most expensive equipment, it's also crucial for your family's comfort, so it makes good sense to know how long you can expect it to last.

HVAC lifespan typically ranges from 10 to 25 years, and it varies depending on the equipment type:

Gas furnaces can last for 15-25 years. Most often, they need replacement due to issues like cracks or corrosion of the most expensive component, the heat exchanger. Split-system air conditioners have lifespans of 7-20 years. The summers here in Oklahoma mean that A/Cs get a lot of use, so they may need replacement sooner due to coil corrosion or compressor failure. Heat pumps and ductless mini-splits can last for up to 25 years. Since these units heat and cool, year-round use may shorten their service life.

Other Factors that Impact HVAC Component Lifespan

Beyond the type of equipment, these additional factors can affect the life expectancy of your home's HVAC components:

Initial quality.

Equipment that's cheaply built is less likely to last over the long term, and it can also have construction or design flaws that shorten its life.

Sizing accuracy and installation.

For a long lifespan, HVAC equipment needs to be sized correctly for your home, and installed with care to the manufacturer's specific requirements.

Preventive maintenance.

HVAC components are like any other kind of mechanical equipment: they perform better, break down less often and last longer when they receive timely preventive maintenance.

Ways to Maximize HVAC Lifespan

Here's some advice to help you prevent life-shortening problems in new HVAC equipment or your current components:Only hire a reputable HVAC contractor when you purchase new equipment. This ensures that a load calculation is done to size the capacity correctly, and the manufacturer's specifications and best practices are followed during installation.Invest in twice-yearly preventive maintenance over your equipment's lifespan so it stays in the best possible working condition.

Regional Efficiency Standards: A Settlement Has Been Reached


Recently, regional efficiency standards for HVAC equipment have been changed by the industry and the Department of Energy. Let's go over what this means for your household.

In 2006, the standard SEER (Seasonal Energy Efficiency Ratio) for air conditioners and heat pumps was raised from 10 to 13. In 2010, equipment manufacturers partnered with efficiency specialists to develop new regional efficiency standards, accounting for different climate conditions throughout the US. In the South and Southwest, SEER requirements were raised to 14, while they remained at 13 in the North.

Equivalent regional efficiency standards and adjustments have also been set for other equipment, such as gas furnaces.

However, the proposed January 2015 adjustments posed a few issues for manufacturers and distributors, so a new agreement has been reached with the DOE. It affects different equipment and regions in different ways.

Before we jump into the new rules, let’s go over a few terms. SEER we’ve already discussed. HSPF is related to heat pump efficiency, and stands for Heating Seasonal Performance Factor. AFUE is for furnaces, and stands for Annual Fuel Utilization Efficiency.

These new regional efficiency standards apply to all equipment manufactured after January 2015.

  • Split system air conditioners: SEER 14 (This number applies specifically to the South, including Oklahoma.)

  • Single package air conditioners: SEER 14

  • Split system heat pumps: SEER 14, HSPF 8.2

  • Single package heat pumps: SEER 14, HSPF 8.0

  • Small-duct, high-velocity systems: SEER 13, HSPF 7.7

  • Space-constrained air conditioners and heat pumps: SEER 12 (Heat pumps must meet an HSPF of 7.4.)

  • Gas-fired furnaces: AFUE 80%

While these numbers will become regional efficiency standards as of January 2015, there’s an 18-month grace period for distributors to sell through equipment manufactured before then.

These developments don't mean you’ll be forced to upgrade your equipment. They do mean that if you purchase new equipment made in 2015 or later, it will comply with these standards, saving you money and reducing your impact on the environment.

Let us know if you have questions. Air Assurance has been serving the Greater Tulsa metro area since 1985, and we’ll be happy to help.
