How to Tell When You Need to Replace Your Commercial HVAC System

Commercial HVAC systems tend to be sturdier than residential systems, as they have to cope with much higher demand over the course of their lives. However, they are not invincible. Every once in a great while, you are still going to have to replace your commercial HVAC systems. Read on for some of the signs that indicate that the time to replace a commercial HVAC system is getting close.

Drop in Output, Rise in Cost

Older systems will accumulate a large amount of wear and tear over their years of use. This wear and tear causes a steady decline in efficiency, resulting in a proportionate rise in operating costs. If your heater or air conditioner is costing more to operate, without actually providing the level of output that it once did, it is a good indication that you need to replace it.

Increases in Repairs

The same wear and tear that decreases the output of your system makes it more likely that the various parts that comprise it will break down under the strain of normal use. Most systems don’t need repairs more than once or twice every few years. A failing system, however, may require repairs as much as three or four times a year. If you have to repair your system that often, you should definitely talk to a professional about having it replaced.


Once a system gets older than twenty years or so, it starts to become much more likely to contract the kinds of problems listed above. If your system is older than two decades, you should keep an extra close watch on it in case it develops any of these symptoms.
