Sooner or later, every HVAC system needs some work. However, sitting back and waiting for a significant problem to arise isn’t a good idea. Instead, it’s crucial that building owners and operators be able to spot signs that the system needs attention. Why? There are a few reasons.
First, the longer an HVAC issue goes without being addressed, the more likely it is that a small problem will turn into a bigger, more expensive one. Being proactive is a very cost-effective strategy.
Another reason to be on the lookout for HVAC trouble is the impact that a failing system has on building tenants, and how that impact reflects on your business. People who are constantly feeling uncomfortable—too warm or too cold—in your building are likely to share their frustration with others, and that can ultimately give you a reputation that causes potential tenants to look elsewhere.
How to Know if Your HVAC System Needs Attention
HVAC system problems can produce many symptoms. Here are six of the most common.
1. Increasing monthly costs. This is one that should quickly get the attention of the person paying your bills. When your HVAC system is working harder or longer than it should to maintain the desired temperature, your energy costs will increase. Of course, small fluctuations based on weather changes are normal, but if you see a significant spike or a concerning upward trend, it’s time to investigate.
2. Unusual smells. Musty or burning odors are probably an indicator that something is wrong with your HVAC system and it should be checked out. Burning odors may occur the first few times you turn the heat on in the fall, but if the smell is especially strong or persists, you should talk with an expert. And, of course, if your system produces actual smoke, you should turn it off immediately and make a determination about whether you should call the fire department.
3. Short cycling. Short cycling is when the system comes on and shuts off fairly quickly and repeatedly. This behavior puts your system under significant stress and should be assessed promptly.
4. Strange noises. You know the sounds your HVAC system makes under normal circumstances. If you become aware of new noises like grinding (often associated with air handler problems) or gurgling/hissing (potentially a leak in the system), it’s important to have the system inspected.
5. Decreased output. If the airflow from your system begins to drop, it’s possible that there’s a problem with the air handler. You should have a professional test the system.
6. Rising humidity. When in cooling mode, your HVAC system not only cools the air in your building, it dehumidifies it as well. If occupants are reporting that they see signs of increased moisture in the air or simply that it feels “sticky” inside your building, this is a red flag and a sign you should get the system inspected.
Stay Ahead of HVAC Issues
Not only can knowing the signs of an HVAC problem help you avoid costly repairs, but it can eliminate hassles for you and your building occupants as well. Having to meet a repair technician and be available while they perform an extensive and lengthy repair process or system replacement isn’t a good use of your time. And creating discomfort or business downtime for building occupants while the system is shut down so that a major repair can be completed won’t make them happy, either. We have identified five common reasons for commercial HVAC systems to begin operating poorly and steps you can take to address them.
