What happens if air handler blower speed is too low?

What happens if air handler blower speed is too low?

This is because the evaporator coil will not be able to adequately dehumidify the space in need of cooling. On the other hand, if the blower speed is too low, your evaporator coil is at risk of “freezing.” This could result in liquid refrigerant floodback that would likely cause compressor failure.

What’s the best speed for an AC blower?

Because this process is complicated, working with an expert in AC repair and maintenance is a worthwhile venture. What is the Recommended Speed for Your Blower?

How much air handler speed does an AC unit need?

For peak performance, most AC manufacturers suggest that 400 cubic feet per minute (CFM) per ton of air conditioning should be used, meaning that 800 CFM should be moving through the evaporator coil for a 2-ton system, and so on.

How can I tell the speed of my air blower?

To calculate your blower’s speed, you will need to measure its external static pressure (ESP). This reading will indicate whether your system has blocked registers or dirty filters. This measurement can be difficult to gather, we recommend working with a technician who has the training needed to understand your system fully.

What happens if the blower speed of an AC unit is too high?

If a blower speed is set too high, your AC might not be operating optimally. This is because the evaporator coil will not be able to adequately dehumidify the space in need of cooling. On the other hand, if the blower speed is too low, your evaporator coil is at risk of “freezing.”

What happens if air handler blows at improper speed?

This could result in liquid refrigerant floodback that would likely cause compressor failure. It is possible that your AC’s air handler blower is functioning at the improper speed, and to maximize its performance, you should make sure that is not the case.

Can you change the speed of an air blower?

Yes you can but we think its just better to know that it can be done whats involved with a simple speed change of your air blower for your furnace air conditioner or heat pump. Ryan from Environmental Heating & air of nc gives you the color codes and speed of those wires.

Why is my furnace blower running at low speed?

Also if you have a high efficiency furnace, there is more of a chance to have the secondary heat exchanger plug up rather than the A/C coil. You can also have a blower motor issue. The motor can be faulty or seizing up causing it to not spin fast enough to move enough air through the furnace.
