If you are noticing some needed repairs, get your local HVAC service technician to take a look. When to replace your commercial HVAC system? Consider a replacement if the unit is 10 years old and you notice a higher energy bill.

What Are Some Reasons To Replace The Commercial HVAC

Believe it or not, there are a few different ways that you can use to determine when it is time to replace the commercial HVAC unit. Let’s take a look at what those might be.

  • Age – if the HVAC system is older than 15-20 years, it is likely time to replace it. How often you use the HVAC system will determine when you will likely need to replace it. Typically at the 10-year mark. Keep in mind that a hole in the heat exchanger can release carbon monoxide into the air and cause death.
  • Energy bill – if you notice that the energy bill in the commercial building has drastically increased, you probably need to replace the HVAC system. Energy efficiency will decrease dramatically over the years.
  • Malfunction – when you start to hear loud noises and squeals coming from the HVAC system, it is likely time to replace it. Additionally, odd smells coming from your system are a clear indication that it isn’t working properly.
  • Outdated – according to the Environmental Protection Agency (EPA), if an HVAC system was installed before 2010, there is an older refrigerant. It is called R-22. Also, this refrigerant is known to cause ozone layer breakdowns and promote global warming. A newer HVAC system can increase your energy output and keep everyone safe.
  • Worker production – as the temperatures fluctuate in the commercial building, your employees will likely decrease their production. Extreme temperatures will have your workers not focused and worried about adjusting to the temperatures.

How Much Does It Cost

When dealing with a commercial HVAC system, keep in mind that it will be fairly expensive. Typically, a commercial HVAC system is meant to cover a large square foot area. Commercial buildings are bigger and typically have many more rooms than your average home. Commercial HVAC systems can range from $15,000 to $40,000 or more.

Other Recommended Maintenance

Now that you have learned about when to replace your commercial HVAC system, there are some areas to pay attention to. One of those is how to stop smells from coming through vents. This involves changing the filters in the HVAC unit and also hiring a professional air duct cleaning service to take a look at your commercial unit. 

Another area is spring HVAC maintenance. No matter if it is a home property or commercial property, maintenance is important.  Springtime is great for this after the colder weather has moved out and warmer temps are heading in.  Cleaning around the HVAC unit is important.  Also, replacing the filter, cleaning the condensing unit, clearing out the condensation line, and adjusting the thermostat are all important. 

Lastly, if you see that your AC is leaking water, there are a few reasons why this might be happening. The air filter may be dirty, the refrigerant may be low, or the drip pan or condensate is broken.
