Top 5 Issues With Commercial HVAC Systems

Top 5 Issues With Commercial HVAC Systems

by ENA Team

HVAC systems are a modern marvel we all take for granted, but which take a lot of work to keep humming. Like most complex equipment, heating and air systems require considerable attention and upkeep. In today’s post, we’ll explore the top 5 most reported commercial HVAC issues and why you should care about them. 

Imbalanced air

Hot or cold air from our central unit travels through a labyrinth of ductwork before it reaches each room. Dampers, which restrict or allow airflow by opening or closing, may need to be adjusted if you’re experiencing extreme temperature differentials from room to room. Alternatively, air may be leaking from the ducts and never making it to the final destination. Check for cracks, particularly in the joints, and seal off any you discover. 

Dirty Filters

One of the easiest forms of preventative maintenance one can perform, changing out the filters regularly can extend the life of your HVAC system. When dirty or clogged, filters force HVAC systems to work harder and increase their output. Another downside to forgetting filters: IAQ may suffer due to overexposure to dust, allergens and other contaminants. 

Deferred Maintenance

Possibly the single best investment you can make in your HVAC system is a preventative maintenance plan. Routine check-ups and service helps identify issues early before they become major repair expenses. When it comes to heating and air, an ounce of prevention is definitely worth a pound of cure. 

Leaking Refrigerant 

Refrigerants, the liquid formula which makes air conditioning possible, is responsible for cooling and dehumidifying indoor air. If your system doesn’t have enough, the air it produces may not be very chilly. The result: less comfortable occupants and an AC system forced to work overtime. 

Thermostat Failures

Last but not least, the thermostat can be the cause (and solution) to a lot of HVAC issues. Placement matters, so make sure your thermostat isn’t located near a heat source, for instance. Also, check to ensure it’s accurately measuring the room conditions from time to time. Finally, consider upgrading to a smart thermostat which can be scheduled to reduce runtime and offers other intelligent features such as system reporting.
