Even a durable, efficient commercial HVAC system may eventually fail. By knowing the signs of potential trouble, building owners can address problems before they get out of hand. Ignoring warning signs can leave the building without proper cooling, heating, and ventilation, and it can result in additional money and time spent. Below are a few signs that may indicate a system in need of service.
Odd noises coming from the HVAC system is a definite indicator that something’s wrong. Building owners should look for grinding signs in particular, as they may indicate failing bearings on the air handler. These bearings limit friction and reduce the workload on the motor, permitting smooth operation. A failed bearing increases resistance upon the motor as it rotates, causing eventual burnout. It’s also important to listen for squealing from the unit. If the system makes these noises when switched on, the fan belt may need replacement. The owner or manager should call for HVAC Service in Lebanon NJ if they hear any sound that’s not normal for the system.
If the system turns off and on many times during the day, it is said to be rapid cycling. This is caused by an overheated condition; when the system gets too hot, the limiter switch shuts it down to avoid fire and damage. Once the system cools, it restarts and overheats repeatedly. Rapid cycling can adversely affect the performance, efficiency, and longevity of a commercial HVAC system.
Uneven Air Distribution
Are some parts of the building cooler or warmer than others are? Such conditions may indicate a power-cycling HVAC unit. If the building owner doesn’t call a professional for a tune-up or adjustment, a small problem may turn into a costly replacement.
Higher Utility Bills
Are the company’s energy bills rising for no apparent reason? A sudden increase may point to a need for HVAC service. Wear, tear and aging can decrease a system’s effectiveness, causing it to use more energy. Owners should monitor their utility bills and electricity usage. If no changes in usage have taken place, the system may need HVAC Service in Lebanon NJ.
If the building’s HVAC is exhibiting any of the above signs, it may be the right time for repair or even a new, more efficient unit. Click here to schedule a free evaluation, and learn just how easy it is to keep a commercial air conditioner in top condition.
