How to Tell When to Replace Your Commercial HVAC System

Your HVAC system is the most important equipment in your commercial building. It keeps your employees comfortable and productive, making it a priority when it comes time to make repairs or replacements.

But how do you know when to replace your HVAC system? While several factors can contribute to the need for a new HVAC system, some warning signs can help determine whether it’s time for a change.

Is the Replacement Worth It?

Before you decide to replace your commercial HVAC system, it’s important to consider whether or not the replacement will be worth it.

While a new HVAC system may cost more than repairing an old one, the cost of repairs can sometimes outweigh the benefits of a new unit over time.

If the system is still working, but you notice a drop in efficiency or an increase in energy costs, then consider replacing your unit.

But before you decide whether or not a replacement is right for you, it’s crucial to weigh your options. And look for the signs that your system needs to be replaced.

Signs That It’s Time to Replace Your HVAC System

  • You Need Frequent Repairs

It is usual for HVAC systems to need repairs from time to time. However, if you have frequent maintenance on your system and the repairs cannot fix it, then it may be time for a replacement.

The frequency of repairs can also indicate whether or not any parts of your system are still functional. If you notice that parts of your unit are not working correctly and experience frequent breakdowns, then a replacement could be in order.

  • The System Is Much Older than 10 Years

More often than not, an HVAC system will last 10 years or more. However, if you have an older unit in place for 15 years or more, consider replacing it with a newer model.

This is especially true if your system has experienced frequent breakdowns or repairs. If you want to get the most out of your HVAC system and save on energy costs, then consider investing in a new one before your current one becomes obsolete.

  • The System Isn’t Keeping Up With Demand

At some point, your HVAC system will be unable to keep up with the demands of your commercial space. When this happens, you may notice that it takes longer for your place to cool off in the summer and long for it to warm up in the winter.

This can be due to several factors, but if these symptoms persist, then it’s time to consider some options for replacing your HVAC system.

  • Your HVAC Ducts are Leaking

Aside from its frequent repair, leaking ducts can be a significant problem for your HVAC system. If you have an older building, holes in your ductwork may allow air to escape. This causes your HVAC system to work harder than it needs to, which can lead to higher energy bills.


Regarding your HVAC system, some things can indicate that it’s time to replace your commercial HVAC system. From high energy consumption and high maintenance costs to ongoing repairs and poor performance, there are many reasons why a new installation would benefit your building.
