Commercial HVAC System Getting Older? 2 Problems It May Have Soon

Posted on

If your commercial HVAC system is getting older, it may start having problems soon. Below is information about two of these problems so you can watch out for them. This will allow you to know when to contact a commercial HVAC repair contractor so you can get your system repaired quickly.

Will Not Cool

If your HVAC system is not cooling your building, this can be due to many things. Contact the HVAC repair company and they will first check the refrigerant to make sure there is enough. If it is low, they will refill it to the right amount and your system should start cooling again. The refrigerant is important as this is what helps the system produce the right amount of cool air for your building. 

There also may be a problem with the evaporator coils. These coils may freeze over during the winter months. They can even do this in the summer months if the evaporator system is not working properly. The contractor will defrost your unit for you and remove the ice that is built up on the evaporator coils. Your unit will then start cooling your business properly. This is commonly caused by not having the right amount of airflow. The air filter may also be dirty or clogged, or there may be low fan speed. The contractor will also check the evaporator coils for any dirt build-up and clean the coils if needed.  

Hearing Weird Sounds

If your HVAC unit starts making weird sounds that are not common, this is a sign that there is something seriously wrong with your unit. The unit may also sound much louder when it is running than it normally does. The HVAC repair contractor will first make sure there are no loose parts inside the unit making the noise. They will also check the access panel to make sure it is fastened properly. 

If you are hearing a squealing sound, this is generally caused by a fan that does not have enough lubrication. This is easy to repair as the fan simply needs to be relubricated. This sound can also be due to a bad fan belt. This can also be caused by a component that is failing and needs to be replaced. A banging sound is usually caused by components that have become loose inside the unit. There also may be a component that is failing and causing this noise. 

Because your commercial HVAC unit is getting older, the repair contractor may suggest that you replace it with a new one. This is especially true if it is going to cost you a lot of money to repair the unit.
