If you have a commercial HVAC system, it is important to be aware of the signs that your system needs repair. You need to know when to call in a commercial HVAC service to work on your unit.
Sign #1: Unusual Sounds and Odors
Your commercial HVAC system is designed to operate in the background. It should not make any weird sounds or emit any strange odors out of the ordinary operating sounds.
If you notice that your unit is starting to make popping sounds and banging sounds, those sounds usually mean that something is wrong with your boiler. Popping and banging sounds mean your boiler needs some immediate attention to avoid more issues with it and your HVAC system.
You need to be very careful with strange smells. If your system starts to smell moldy, that may mean you have mold or mildew inside of your ducts. If you are smelling something like stinky eggs, that could mean you have a gas leak. If you think you have a gas leak, you need to evacuate your building, call emergency services, and call for some emergency HVAC services to deal with the leak.
Sign #2: Rising Utility Bills
If you notice that your utility bills are rising, that is not something you should ignore. Rising utility bills are often a sign that your HVAC system is not working properly and needs repairs.
When your HVAC unit isn't working properly and a part is broken or malfunctioning, your system will compensate by running more and taking up more energy, which will drive up the cost of your utility bills. If you have not changed the amount of energy you are using but your energy bills are on the rise, you need to get your HVAC unit inspected, as it uses a lot of energy and is more than likely responsible for the rise in your utility bills.
Sign #3: Heating Issues
Finally, you need to pay attention to how your system works. If the heating and cooling are not consistent throughout the building, that can be a sign that your system is not working correctly anymore. If people complain that the air is different from the thermostat, something isn't working correctly within the system. It may be a small part that isn't working correctly but is causing a large issue with your system.
If your commercial HVAC system is making unusual odors and sounds, is raising your utility bills and is resulting in heating issues, it is time to bring in a commercial HVAC professional to fix your system. You should always fix issues as soon as they appear with your commercial HVAC system.
