Signs You Need to Have Your HVAC System Replaced 

A functioning HVAC system is essential for the comfort of your home. It's important to watch out for signs that your unit may need to be replaced, as repairs can cost a significant amount and you'll benefit from having improved efficiency and better performance when you upgrade. Here are some key indicators that it might be time to replace your old HVAC system.  


The average lifespan of an HVAC system is 10-15 years, so if your current system is more than 15 years old, it's likely due for a replacement.  

Unusual Noises

If you notice any unusual noises from your HVAC system, such as grinding, rattling, squeaking, or humming, this could indicate that you need a new unit.

Inadequate Cooling/Heating

A lack of cooling or heat output could indicate that your current system needs replacing, as an old or failing unit will not operate at its peak performance level.

Increased Energy Costs

Over time your energy costs may rise significantly if your current HVAC unit is not running optimally anymore due to age or other issues.

Unusual Smells

An odd burning smell could mean trouble with your current unit and likely means you should look into getting it replaced. If you experience this issue, contact us and find out how soon you may need to look into an HVAC unit replacement.

How Often Should You Replace an HVAC System? 

The health and longevity of your HVAC system depend on several factors, including the type of installation, the model and make, usage frequency, and maintenance regimen. Generally speaking, the average lifespan of a good-quality HVAC system is around 15 years; however, different signs can indicate when it may be time to consider HVAC replacement. 

Paying close attention to changes in energy bills or shifts in temperature when you have not changed settings or increased usage can indicate an inefficient unit. Furthermore, corrosion around any part of the system or air leaks from ducts can also suggest it is time for replacement.
