One of the telltale signs that your commercial heating unit is need of repair is if the unit stops producing heat and heating up your commercial building. Fortunately, it is uncommon for a heater to suddenly stop working one day without giving you signs that something is wrong. Unfortunately, most people do not know the signs that a heating unit gives them that indicate a repair may be needed. Here are a few of the signs that your commercial heater may be in need of repair. 

The Unit Is Making Atypical Noises

One of the signs that your commercial heating unit may give you if it is in need of repair is strange noises. When a heating unit is heating air, it often has a low hum to it. This is a sound that you may be familiar with and may drown out. But when something is wrong, your unit may make noises that you are not used to hearing. The unit may clang, bang, grind, squeal, or whine. When this sound is first present, it may not be heard continuously. As such, people dismiss it. But you should never dismiss any strange noises you hear from your unit, even if they seem to go away. They will always come back, and more damage can occur. 

There Is Weak Airflow

Another sign that your commercial heater may be in need of repair is weak airflow. You may notice that your commercial unit is not heating as quickly as it did before, or you may feel a weak amount of air flowing out of the vents in your space. This is a sign that your unit is struggling to heat your building and that repairs are needed. 

Your Energy Bill Has Suddenly Spiked

The final sign that your commercial heater may be in need of a repair is an energy bill that has suddenly increased for no reason. If your energy bill has increased when you are using your heater, your heater may be working longer and harder to heat your commercial building, resulting in the energy increase you are seeing. Call in a professional to find out what is going on and get your bill and commercial heating unit under control. 

If you notice one or more of these signs, your commercial heating unit may be in need of repair. This is the ideal time to call in a commercial heating and cooling professional to inspect your unit. This allows you to get your unit inspected and repaired before it stops working altogether. Visit a website like http://www.mercurytecinc.com for more information.
