HVAC stands for heating, ventilation, and air conditioning. It regulates the heat and ensures proper ventilation in an area. It improves the comfort of occupants. You should check your unit if you still feel hot even when your air conditioner is set at max. There are several reasons why your hvac humidity control might not be working. Here are the most common ones.
Air-conditioner is too large for the space
The size of an air-conditioner is usually based on its cooling capacity. Not on its physical structure. Most people think that an air conditioner cannot be too big to do an efficient job. A bigger system does not provide better HVAC humidity control. As well as cooling. Big air-conditioners have a powerful compressor. This turns on and off at a frequent interval. It does not run long enough to have humidity removed from the air. A load calculation process determines the proper size of air-conditioner an area needs. A qualified HVAC company should choose your air-conditioner. They should also install it. If a builder chose and install the air-conditioner, it is most likely to end up with an oversized unit. Installing an air-conditioner with a smaller capacity will fix this problem.
Limited to a single speed
An air-conditioner that only has an on and off button can have the same problems as an oversized one. A unit that can only run at one speed turns on and runs at full blast. It does so until the air reaches the set temperature. After that, it turns off until the temperature goes above the thermostat threshold. It does not run constant enough to remove humidity. This often happens when the temperature is too high and the air is very humid.
Negative air pressure in space
A ventilation system with a poor design causes negative air pressure. This means you are venting too much air. This often happens in a restaurant with a powerful kitchen exhaust system. The air tries to balance itself when negative pressure is present. It draws in more outside air. This is the case when someone opens an outside door. A gust of wind enters the room. Every little opening in the building can also draw in outside air. When relative humidity outside gets high, all that air is being drawn into the building. Your air-conditioner may not be able to keep up if the problem gets worse enough. The HVAC humidity control may get compromised. Your ventilation system design needs a change if this is the issue.
Sometimes you are not ready to have an air-conditioner or ventilation system replacement. You can try different measures to boost your system’s capacity and ability. Contact a professional if you need help with your HVAC humidity control system.
