Commercial HVAC units are often mounted on the roof which makes it difficult to perform routine physical inspections. Often, mechanical problems such as cycling issues, coolant leaks, or damaged mechanical components can best be detected by listening for irregular or atypical sounds coming from ductwork. This is especially the case when the unit turns on or off. Clanging, grinding, or screeching noises indicate a potential problem that will only become worse (and more expensive to fix) if ignored.
There are a number of potential causes why a system is unable to maintain optimum temperature in your commercial building. These include damage or leaks in ductwork, malfunctioning thermostats, or mechanical problems with the HVAC unit. If the building has been expanded or its use has changed, it’s possible that the HVAC system is no longer powerful enough to support the space. A professional service technician will be able to quickly diagnose the problem and then provide possible solutions to return consistent temperatures to the building.
Even though it’s your building, the people working or occupying it likely have an acute sense of how or where the HVAC is not properly performing. Do you notice some people dressed in layers while others walk around looking flush all day? Listen to employees – if they indicate that some rooms are too hot or too cold, there may be a problem with the HVAC unit that requires maintenance or repair. The longer you wait to have the unit serviced, the worse the problem will become (and your employees or tenants will continue to grow unhappy).
Regardless of its use, no commercial building benefits from strange smells coming from air vents. Musty, burning, or even rancid smells are a sign that something is wrong with the HVAC unit. A foul odor leaves a strong negative impression on everyone who visits the building.
Pay attention to how often the HVAC unit turns on and off. A properly functioning compressor and thermostat should keep temperatures consistent without constant cycling. Not only does this create unnecessary strain on the unit but it is also incredibly inefficient.
The process of drawing in warm air, cooling it, and pumping it into the build causes condensation to form. If the unit is functioning correctly, moisture will be emptied by way of the drain tube. If this is cracked or gets blocked, water will pool in the system or begin leaking. If you notice water around your HVAC unit or there are signs of water damage on the roof or ceilings in the building, it is a clear sign that repair is necessary.
Managing utility costs for a commercial property is a constant struggle. If you notice that electricity bills are increasing without reasonable cause, it may be the result of an inefficient or poorly-working HVAC unit. Don’t let the problem go unaddressed, leaving you to pay more than you’ve come to expect. The cost to repair will not only make the facility more comfortable but lowers operating costs by returning the system to peak efficiency.
