If you aren't getting a sufficient amount of heat when you turn on the office HVAC system, it might be due to the furnace. There are a variety of things that could be causing this issue, from needing to replace the filter to issues with the vents in the individual office spaces. Here are some common reasons to not have enough air coming from the furnace.
The Filter is Clogged
One of the more common reasons to not have a good amount of air from a furnace when the heater is turned on is a clogged filter. The air filter in the furnace helps to capture dirt, debris, and dander to keep it from entering the office space through the vents. However, the filter can get clogged from all this debris and then need to be replaced or cleaned. You will first need to know what type of filter the furnace has; replaceable filters can be thrown away and replaced, while reusable filters will be cleaned, then put back in the furnace. If it is an older reusable filter that is clean, but still causing air flow issues, it might be time for a new one. When cleaning a filter, make sure it is rinsed clean and dried before replacing it.
There Are Duct Issues
There are also a variety of issues with the building ductwork that could be causing air flow issues when turning on the heater. For example, if there are breaks in the ductwork, it will cause warm air to disappear or escape before it makes it way out of the vents. The air pressure often drops and you don't get sufficient heat. You may also notice this problem if you have higher energy bills all of a sudden as a result of using the heater. Another duct issue that can cause lack of proper air flow from the furnace is when the original ductwork that was installed is not the right size for the building and number of rooms. The ducts might be too small or too large for the heating needs for your offices. An HVAC technician can help you with both of these duct problems.
You Need More Vents
Also make sure you have enough return air vents in the building. You might have built new offices by separating a large office into two smaller offices, but one of the small spaces doesn't have proper heating vents. Without enough return air vents in the building, you might experience air flow issues from the furnace. This is something else an HVAC professional will be able to remedy for you.
