Charlotte HVAC.pngWhen trying to balance all the different tasks that come with managing a large commercial facility, it pays to learn how to quickly diagnose and fix problems when they first appear rather than waiting until they get worse.

To that end, we are offering this quick, practical guide to help you identify and reverse three common commercial heating and cooling HVAC problems that may occur in your building:

Problem 1: Poor air quality

If tenants in a certain part of the building begin complaining about the air being stuffy, about odd smells with no obvious cause, or other issues with the quality of the air, it’s likely a sign that maintenance is needed on one or more of the air ducts into that area. If the air quality issue is affecting most or all of the building, the problem is more likely in the mechanical equipment itself.

Some common causes of poor air quality include:

  • Dirty air filters
  • Condensed water that’s become stagnant
  • Melted debris on the heat exchanger
  • Mechanical parts that are overheating

The Solution: Routine maintenance

In all these cases, well-planned and strategically scheduled routine maintenance can usually catch these issues before they escalate enough to harm air quality. A comprehensive planned maintenance program includes periodic visual inspections of the ventilation ducts and machinery, and diagnostic tests to determine if any parts need to be repaired or replaced to prevent future issues.

Problem 2: Unusual noises coming from the vents

Heating or air conditioning vents making loud or erratic sounds can be a real annoyance for those occupying the building, from tenants to clients and customers. Likely causes of noisy ventilation are:

  • Loose or broken fan blades
  • Cracked or broken air ducts

In rarer cases, the sounds are emanating from the heating or cooling units themselves. If the unit is accessible, this can be determined by locating it and listening to hear if the sounds are louder near the unit, and if they correspond to what is being heard elsewhere in the building.

Solution: Get professional help to isolate and eliminate the problem

In both cases - whether the noises are coming from the vents or from the heating or cooling units - isolating and resolving the issue will often require expertise and equipment not available in-house. In this case, contact your local, trusted commercial HVAC company to have an experienced technician assist with the problem.

Problem 3: Rising energy bills

In some cases, a problem presents itself on paper rather than through anything you or your tenants are going to notice. The heating or cooling system may still be maintaining a comfortable temperature and good air quality throughout the building, but you notice that your monthly energy usage is rising with no simple explanation.

Likely, the system is struggling to perform efficiently due to an underlying problem, and is needing to use more energy to maintain a comfortable environment. This can happen for many reasons:

  • Equipment and ducting that needs to be cleaned
  • Equipment that is nearing the end of its expected lifespan
  • One or more system components that is malfunctioning or not functioning, requiring others to pick up the slack
  • Electronic controls that are malfunctioning or require recalibration

Solution: It depends on the root cause

All of these issues require different solutions, and the most effective option is to have a trained technician come in to perform an operational assessment and conduct a thorough inspection in order to properly identify the root cause(s).

One option to help make this process faster and easier, is to install a building automation and analytics system to control and monitor your HVAC system via electronic sensors. Some modern HVAC systems can incorporate machine learning and artificial intelligence to continually optimize the system to make sure it’s running as efficiently as possible and that you are aware of any issues as early as possible.

Of course, building automation and analytics can be a big step and a sizable investment, so it’s important to consider your current HVAC system’s health and lifespan first.
