Top 20 Signs It’s Time for a Commercial HVAC Replacement

As a business owner in South Florida you know how important your space’s climate is. Your AC unit runs almost year-round to keep inhabitants cool and comfortable. That’s why you need to be able to spot the signs it’s time for a commercial HVAC replacement.

When you know what to watch out for you can plan the replacement around your facility’s schedule. Otherwise your HVAC system can—and likely will—fail at the absolute worst moment.

So always be on the lookout for any of these telltale commercial HVAC issues:

1. Inconsistent Temperatures

If one room is freezing cold while another feels hot and humid, something isn’t right with your HVAC system. It could be something simple like a clogged air filter or one of the signs it’s time for a commercial HVAC replacement.

2. Poor Air Quality

Is your facility’s air stuffy lately? Maybe to the point that employees and customers are complaining about feeling suffocated? This means air isn’t being filtered through your system correctly. The cause may be damaged ductwork or faulty HVAC components.

3. Weak Airflow

Your thermostat says everything is running properly, but there’s barely any airflow coming through your vents. Plus, it takes longer to heat or cool your facility—which means higher utility bills. If this sounds familiar, your HVAC system may be at the end of its lifespan.

4. Humidity Problems

Here in South Florida, humidity is part of daily life. But it shouldn’t be a problem that plagues your business’s interior. Excessive humidity and extreme dryness are both indications that your HVAC equipment needs repair or replacement.

5. Strange Noises

Rattling, grinding, squealing, clunking, and hissing are all bad sounds when it comes to commercial HVAC. Hearing these noises coming from any part of your system is typically one of the clear signs it’s time for a commercial HVAC replacement.

6. Longer Run Times

It’s not normal for an HVAC system to randomly need more time in order to fully heat or cool your space. Longer cycles often indicate degraded coils or a failing motor. These parts can typically be replaced, assuming no other major issues exist within the system.

7. Rising Energy Bills

Are your energy bills rising without a corresponding increase in system usage? This can only mean your HVAC equipment is losing efficiency, which can happen for several reasons. But no matter what the root cause is, higher bills are one of the most common signs it’s time for a commercial HVAC replacement.

8. Repair vs. Replacement Costs

Compare your recent HVAC repair costs to the cost of a new HVAC system for your facility. As a general rule, if the repairs would cost about half as much as a new system (or more), you’ll want to consider just doing a full replacement—you’ll get more bang for your buck, plus a manufacturer’s warranty in most scenarios.

9. Obsolete Technology

HVAC automation, controls, and technology have come a long way in recent years. If your current thermostat and software have become inefficient or difficult to work with, odds are your entire HVAC system could use an upgrade.

10. Using R-22 Refrigerant

Many older models of commercial HVAC units use R-22 refrigerant. However, it contains chlorine, which can be harmful if it leaks into the air. That’s why R-22 units have now been phased out—if you still have one, buying the refrigerant is both difficult and expensive.

11. Poor Physical Condition

There are many physical signs it’s time for a commercial HVAC replacement. For example, frozen or dirty coils, a faulty blower fan, or clogged drain lines. At All Pro Mechanical, we check for issues like these with every routine HVAC inspection—trying to tinker with these delicate components on your own isn’t recommended.

12. Declining System Performance

As AC units get older, they don’t perform as well—especially in Florida’s intense climate. Have you, your employees, or your customers noticed an overall decline in your space’s comfort? If so, your HVAC unit may be due for a replacement soon.

13. Safety Concerns

In extreme scenarios, there may be real safety concerns related to your commercial HVAC system. Electrical risks, fire hazards, and even carbon monoxide leaks are all dangers associated with major HVAC issues.

14. Energy Efficiency Issues

The US Department of Energy sets specific guidelines for energy efficiency and HVAC equipment. But this isn’t necessarily bad news—the more efficient an AC unit is, the lower your energy bills will be. Spending now on a commercial HVAC replacement will save you quite a bit in the long run.

15. Non-Compliance with Regulations

New environmental regulations are rolled out often in the US. As a business, you’re required to meet these—or face serious fines from the EPA. Older models of commercial AC units often miss the mark, and commercial HVAC replacement is typically cheaper than EPA fines.

16. Missing Sustainability Goals

Your commercial HVAC system is a major factor in reaching your business’s sustainability objectives. Evaluating details like the SEER rating allows you to identify which options align best in terms of efficiency, sustainability, and eco-friendliness.

17. New Technology Integration

Integrating your HVAC system with smart building technology can be a real game changer. Having full control over climate and efficiency at your fingertips often means lower utility bills and extending your HVAC system’s lifespan.

18. Changing Business Needs

If your business’s main purpose or services have changed recently, you’ll want to consider a commercial HVAC replacement. Maybe you need more ventilation, or your cooling requirements have changed. It’s crucial that your HVAC unit is suited to the task.

19. Unpleasant Odors

Bad odors are one of the more urgent signs it’s time for a commercial HVAC replacement. If you smell mold, mildew, or a “burnt” smell, especially near air vents, you should get an HVAC replacement estimate sooner rather than later.

20. Visible Signs of Decline

Take a look at some of your visible HVAC equipment. Do you see rust on any pipes or components? Build-ups of scale or moisture on walls and windows? These indicate your HVAC system hasn’t been able to do its job properly in some time and may require replacement.

Questions to Help You Decide if It’s Time for a Commercial HVAC Replacement

It may be time for a commercial HVAC replacement even if the above signs aren’t present in your system. Asking yourself the three questions below will help you get a clear picture of whether a new system would benefit your business.

Has your business space expanded or been reconfigured, requiring a different HVAC setup?

Commercial HVAC systems are set up based on a space’s layout and square footage.

Changing either of these factors without replacing or updating your equipment can lead to an uncomfortable building climate and sky-high energy bills. Your AC unit’s lifespan is likely to be far shorter, too.

Are your business’s HVAC repairs becoming more frequent and costly?

All systems with moving parts will need maintenance eventually. So, it’s normal for your current HVAC equipment to need occasional repairs.

But if you’ve noticed these repairs becoming more frequent and more expensive, it’s likely time to look at the cost of HVAC replacement.

Is your HVAC system more than 10 – 15 years old?

Most commercial HVAC systems have a lifespan of 10 – 15 years. This is especially true here in South Florida, where our climate puts your equipment through its paces year-round.

Regular HVAC maintenance can help you extend your system’s lifespan up to 15 years. But once your system has reached around 10 years of age, it’s wise to start budgeting for and researching commercial HVAC replacement.
