Here are the top 5 most common commercial HVAC problems that you should know:
Neglected Maintenance
Minor HVAC system problems can turn into higher repair costs. If you neglect proper HVAC maintenance near Blue Bell, PA, a system failure is also very likely to happen.
If you don’t want it to happen to your equipment, you need to hire an expert to identify and fix the issues. That way, your system will keep running in its best condition.
Clogged and Unclean Filters
Worn-out and dirty filters force your air conditioner to work harder—increasing energy costs and reducing its longevity. Regular checking and periodic replacement of your filters will keep your HVAC system running in optimal condition.
Additionally, it will improve the IAQ of your commercial building by removing dust and other air pollutants. So, be sure not to forget this on your A/C or furnace maintenance checklist in Blue Bell, PA.
Refrigerant Leak
Refrigerants are liquid agents contained in the coils of an HVAC system that cool and dehumidify indoor air. If your system lacks refrigerant, then it can’t perform its job.
This problem not only leaves your indoor air extremely hot and uncomfortable but also causes the condenser to work tirelessly, leading to incredibly expensive A/C complications.
Thermostat Breakdowns
When problems show up, it’s easy to assume that your HVAC system is the issue. However, the problem may only be with your thermostat. The thermostat is responsible for regulating the timing and amount of cold or hot air your system should produce. If it’s malfunctioning, you can suffer from irregular temperature fluctuations.
Poor Airflow
Before the heated or cooled air reaches the room from the vents, it will travel through a series of ducts. Dampers regulate this by decreasing airflow and letting more conditioned air go to other areas. If some areas cool or heat more quickly than the others, the dampers are not balanced.
