Commercial HVAC systems are under a pretty heavy load this season, with record heatwaves washing over the country. That’s not likely to change any time soon, so it’s a good idea to know what to look for when it comes to identifying commercial HVAC problems. Hopefully, you’ve already had preventive maintenance done on your system this season to ensure that it’s in the best shape it can be. Maintenance is never perfect, though, You still need to keep an eye out for any problems that might crop up between appointments. The following are just a few of the issues that can afflict your commercial system.
Do you have fluid leaking from your system? Is the system struggling to provide as much cooling as it normally does? It’s probably a refrigerant leak, then, and you should call for repairs as soon as possible. Refrigerant is the fluid that the system relies on to keep the building cool. It cannot operate without refrigerant. As the refrigerant level in the system drops lower and lower, so too will the system’s output capacity. Eventually, this will reach a point where the system breaks down entirely. You should have a technician repair the system before that happens.
Short cycling is when your system turns itself on and off every couple of minutes instead of completing a full cooling cycle. It’s often due to an electrical issue, though at times a malfunctioning compressor can also cause this problem. Regardless of the cause, though, the problem itself is very dangerous to the health of the system.
Short cycling increases the wear and tear the system suffers over time. The longer the system short cycles, the more likely it will be to develop other problems and the shorter its effective lifespan will be. If your system is short cycling, it’s imperative that you call for repairs as soon as you can. Otherwise, you might be scheduling a full system replacement sooner than you thought.
If you see ice building up on the coils of your commercial air conditioner, then you probably have an issue with either the air filter or the air handler. Both issues have a tendency to cut down on the amount of air the system circulates, which causes serious issues for the coil. The coil will eventually freeze over, causing the system’s output capacity to drop significantly and opening the way to all kinds of other problems. If you have ice on your air conditioner, we recommend that you consult with a professional as soon as you can about fixing it. If it isn’t dealt with in time, it can lead to the entire system breaking down.
