What is the Life Expectancy of a New HVAC Unit?

One of the biggest questions homeowners have regarding their HVAC system is how long it should last.  HVAC is a big expense, but it provides us with a great service.  In the dog days of summer, we can count on keeping cool and comfortable inside our homes, and in the frigid days of winter, we can count on staying warm and comfortable.

The Short Answer

The short answer about the average lifespan of an HVAC unit is 20 years.  A more accurate answer is that units can last anywhere from 10 to 30 years.  Much of the difference in longevity is the quality of the system that has been installed, and the maintenance it has received during its lifetime.  Do you regularly change filters and do you have it inspected and cleaned?  The more upkeep you give your system, the longer it should last.

The Benefits of a New Unit

The truth is that every appliance will cease to work eventually.  A general rule of thumb is that if an appliance costs more than 25% of a replacement unit, it is time to consider a replacement.  There are advantages to replacing your HVAC.  Newer systems can help reduce allergy causing particles in the air.  Even people without allergies can breathe easier with newer systems.

Other advantages from new systems is they are also quieter than older units.  The older a unit is the more it will probably gain vibrations which will add noises.  Newer systems should be built with more sound dampening construction as both the materials that are used in building these systems have improved, and the materials are better too.  It is not unusual to have new systems that are at 60 decibels or even quieter.  Homeowners may not even notice how noisy their existing, older systems are, but they will notice and appreciate the quiet after purchasing a new system.

New units are more efficient.  This means the expense to run your HVAC system will be lowered, and less energy is wasted.  Less energy is wasted and that is not only good for an owner’s utility bills, but it is better for the environment. Homeowners will also appreciate that these newer appliances more have better warranties. 

Treat your HVAC system the way manufacturers recommend and whatever system you have should last an average of 20 years.  When it does start to be too expensive, you’ll really like the upgrades that are available compared to the last time you made that purchase.
