HVAC air flow problems result in uneven temperatures throughout a commercial space. Not only does this lower comfort, costs increase because of inefficient energy usage, air leakage, and more. Estes Commercial in Atlanta, Georgia aims to inform commercial HVAC owners about these issues so they are able to rectify their air flow issues and prevent the problems that commonly result.
Common Commercial HVAC Air Flow Problems
Commercial properties experience HVAC air flow problems when one or more of these issues are present. Thoroughly inspect the HVAC system to pinpoint the root of the issue.
- Slow fans
- Dirty coils
- Refrigerant levels
- Size problems
- Outdated design
- No maintenance
Obstructions cause HVAC air flow problems all throughout the system. Condenser units, vents, registers, and ducts all need to be clear of any obstructions to receive adequate airflow for proper operation. For condenser units, clear away any debris around the unit. Next, move any furniture in front of vents and registers and make sure they are clean. Lastly, clean the ducts. They accumulate dust just like other parts of the system. Fix any damaged or obstructed duct sections to restore air flow and limit energy losses.
Check the filters on HVAC equipment regularly to improve air flow and air quality. Air becomes stuffy and doesn’t flow correctly through the unit when the filters are dirty. Dirty filters are a leading cause of HVAC air flow obstructions that cause system damage. Change the filter as often as instructed by the manufacturer’s instructions. Additionally, check the filters semi-regularly to see if they need an early change.
Check if the thermostats work throughout the space. Faulty thermostats, low battery power, and location all impact air flow. Poor temperature readings and signals may not send proper air volumes through the system, generating discomfort indoors. Outside heat sources impact thermostat readings, so proper positioning is critical – if the thermostat sits in direct sunlight, move it somewhere out of the light and away from heat sources, cold spots, doors, and windows.
If fans within the system move too slowly, they create HVAC air flow problems. Not enough air moves through the system to prevent overheating and deliver effective temperature control. The fan either needs to be cleaned, or the blower motor requires attention.
Coils in HVAC systems must be clean to adequately provide a commercial space with conditioned air. They are often the side effect of dirty filters, which impede air flow. Clean all of the coils on the HVAC equipment to ensure they are unobstructed. Dirty coils work harder and run hotter, which decreases efficiency and increases energy bills.
Low refrigerant levels impact air flow because the unit doesn’t produce as much cool air. Leaks are the most common cause for this issue. All refrigerant issues must be done by an HVAC technician because it is highly regulated and dangerous to handle.
The size of HVAC units in comparison to the space they heat or cool and its demands impacts the functionality. If a unit is too big or too small for a space, the air flow suffers. Hot and cold spots are more common, and some areas receive no hot or cold air at all. The only way to fix this issue is to invest in a unit that correctly fits the space.
Older units experience more HVAC air flow problems because they don’t have the same technology as newer units. Outdated duct work is one of the more common issues. If the layout of the space changes at all, the duct work must also change to accommodate the new layout.
Poorly maintained systems experience HVAC air flow problems more than properly maintained ones. This is because HVAC specialists are able to identify problems early during maintenance visits, and offer advice about how to increase air flow if the customer asks.
