Signs That It’s Time to Replace Your Commercial HVAC System


When it comes to running a business, it’s undeniable that our top priority should be the comfort and safety of our customers and employees. The moment customers enter our establishments, we want them met with cool and soothing air. At the same time, we also want our employees working under comfortable conditions which contributes not only to their productivity, but also to their good spirits. With that in mind, I am sure we can all agree that our building’s HVAC system has a part to play; and so maintaining them at a controlled and stress-free level is something that we should not take lightly.

It is advisable for business owners to always pay close attention to the condition of their HVAC systems. Unfortunately, there will be times when a heater, boiler or air-conditioner will be in need of replacing due to a variety of reasons. We at Level One HVAC make it our business to provide nothing but the best in terms of services for you and your commercial HVAC systems, which is why we are providing you with a quick guide on signs that it may be time to replace your old HVAC system.

System Malfunctions

If you notice that your HVAC system is functioning differently from its normal or optimal capacity, it might be a sign that it is in need of repair or replacement. For instance: grinding, rattling, hissing or clunking sounds inside your machines can indicate loose or broken parts. Whether it’s the bearings in the motor or a loose fan belt; leaving parts broken or unattended to is an easy way to further compromise your HVAC system.

Another malfunction to look out for is if your machines short-cycle. If your HVAC units are constantly or randomly turning on and off during the day, it either means your system is overheating or not getting enough power to keep itself running. Having faulty wiring or overheating in your machines are a big safety hazard; this is something no business owner can afford to risk.

Bad Air Quality

The quality of air that our HVAC systems produce should be clean, crisp and consistent. If you notice that different areas of your establishment have different temperatures, it is possible that your HVAC system is unable to function at its required and optimum capacity.

HVAC systems that are not properly maintained also have the tendency to develop leaks which may expose people to harmful and toxic chemicals. Always be aware of any foul or strange odors coming from your machines. Also be aware of any unusual flu-like symptoms in people within your establishment; this is a sign of carbon monoxide poisoning. Carbon monoxide is a colorless, odorless, and tasteless gas that can leak from various sources. Exposure to these harmful chemicals may lead to serious health problems or worse.

Increase in Electric Bill Costs

One way to know if your HVAC system needs replacement is if you notice a drastic increase in your electric bill.

Compare your bills from the past six months and see whether it is consistent. If there is an unusual upward trend or increase in costs, it is a sign that your machines are struggling and working at a rate higher than normal. When HVAC systems are damaged or too old, they also become prone to current fluctuations.

Overall Age

If your HVAC system is in constant need of frequent repairs, it is possible that your system is nearing the end of its expected lifespan. Heaters and boilers have a suggested lifespan of 18-24 years while air-conditioners have that of 10-15 years. Anything past that will surely merit replacement. Knowing your system’s lifespan and repair history can help you determine the best course of action. More often than not, when it comes to old HVAC units, it is cheaper to opt for replacement rather than continuously shelling out money towards repairs.

While these are only a few examples of signs to look out for, it also pays to consult with a professional HVAC technician for a proper diagnosis of your HVAC system.
