Signs that your Commercial HVAC Unit needs Replacement

When it comes to the HVAC system in your commercial building, you will want to make sure that everything is functioning as expected. If you believe there may be a problem with your HVAC equipment, then read on for some signs that indicate it’s time for a replacement. The first sign would be if the air conditioning and heating units are not working correctly and cannot provide adequate comfort levels.

Another indication is if the system seems inefficient and uses more energy than usual. Here are some other signs that your commercial HVAC equipment needs replacement so let’s get started.

Unusual Noises or Odors

It’s alarming when your HVAC system starts making strange noises, such as grinding or squealing. These sounds indicate a severe issue with the equipment. You should take notice immediately to prevent further damage. Or the other thing is if you notice any unusual smells coming from inside of it. Then it may be an issue with indoor air quality that poses risks for all those living close to them.

Unexpected Increase in Utility Bills

HVAC systems are vital for a building’s temperature control and comfort. If your utility bills have been increasing an abnormal amount, it could mean that you’re not getting the most out of your inefficient HVAC equipment. If this has become a chronic problem, HVAC units may need replacing in some cases, so make sure to get checked by professionals at JDC Mechanical as soon as you can.

Equipment is at the End of its Lifespan

It’s always best to replace your HVAC equipment before it becomes too costly. If you are experiencing any problems with old, worn-out units and feel like they may be the source of an issue (or if their regular maintenance isn’t solving anything), consider investing in new models.

Increase in Moisture

You might see condensation on your AC or furnace unit. It could be a sign that there is moisture building up and needs your attention immediately. Before it causes further damage, but an increase in humidity inside may indicate something more serious may have gone wrong, such as leaks requiring HVAC service or replacing your HVAC system.

Loss of Energy from Exhaust

We are always looking for ways to help you cut costs. One of the best tactics they can use is replacing your old, inefficient HVAC system with a new one that will reduce energy loss by 50 – 80%. When this happens, you’ll enjoy lower monthly bills and see an increase in cash flow over time.


A commercial HVAC system is a complicated unit that keeps your workplace comfortable. However, if it’s beginning to fail due to moisture or rust, then you need to investigate and plan for repair or replacement. Replace your unit before things get worse and ambient temperatures change causing any occupants to lose confidence in your management because replacement can save money on repairs down the line.

When You Feel Discomfort

If you’re experiencing problems with high humidity or a sterile hot office environment, then your air conditioning system needs service. Suppose the condenser fan doesn’t seem to be providing adequate cooling.

In that case, there may be a separation between ductwork and blowers because of inconsistent airflow caused by blockages that need attention before they cause further damage. When you have an HVAC system in disrepair at your office, complaining about discomfort is the leading cause of its replacement.

Air Quality is Getting Worse

When your HVAC system is not maintained correctly, you may notice that different establishment areas have fluctuating temperatures. If this happens, it can be because there are leaks in their system which expose people to harmful chemicals and toxins. Breathing vapor from hot water or cooling piping without protection could cause lung disease or cancer.  Routine air changes are also crucial to keep air quality safe for occupants.  Read our recent article on keeping buildings safe during COVID and when it’s time to replace your HVAC system, please contact us first. 

Age of HVAC System

You should replace your HVAC systems at the end of their lifespan, 18-24 years for heaters and boilers. Air conditioner life spans vary depending on how often they’re used but can stretch up to 15 years before needing replacement too far past this point; usually, it’s cheaper, though, because repairs cost more than purchases do in most cases.  Follow your manufacture’s guidelines for lifespan, maintenance and repair in all cases.

Final Words

If you’re noticing any of these signs that your commercial HVAC equipment needs replacement, it might be time to start thinking about the next steps. You can call a professional for the service of your HVAC system or, more often, for its replacement. A professional will also make sure all parts are replaced as needed, not just patched up temporarily.   It’s easy to forget that your heating and cooling system is a vital component of your property. Be sure to consult with professionals who can identify any problems before they become serious issues and can assist with both commercial HVAC equipment selection and sizing.
