HVAC Humidity Control: 5 Reasons Your AC Is Ineffective

Dec 20, 2022 | 0 comments

Isn’t the purpose of air conditioning humidity control to eliminate humidity? Why, then, does yours not function properly? Maintaining a humidity level between 40 and 60 percent for most rooms is essential for reasons other than comfort. Read on to find out more about HVAC humidity management and why your AC might not be capable if you’re sweating your way through another steamy August. Then, to prevent your room from seeming like a tropical rainforest, we’ll explain four ways you may make an older unit remove more moisture.

Your air conditioner is too big for the room.

First of all, when we discuss AC size, we are referring to cooling capability rather than the unit’s actual size. People may need clarification regarding other aspects, like the size of an AC unit.

To argue that your air conditioning humidity control is too big to complete the job efficiently is counter-intuitive if you’re not an HVAC specialist. A larger system could offer more significant HVAC humidity management in addition to cooling.

Sadly, the response is no. The truth is that an enormous AC system performs poorly at regulating both humidity and temperature. The device never works long enough to remove humidity from the air because the strong compressor rapidly switches on and off.

Using a load calculation procedure, you should carefully calculate the size of your AC. There is a considerable risk that your AC was picked and installed improperly if a builder did it as opposed to a licensed HVAC provider. That is how many residences and commercial establishments have come to have enormous HVAC and air conditioning humidity control devices. To solve this issue, you need to install a lesser-capacity AC system.

Your AC can only run at one speed.

When it comes to HVAC humidity management, an air conditioner that can only operate at one speed—basically, on or off—may experience the same issues as one that is too big.

The machine starts up and works at full power until the air reaches the desired temperature when it can only operate at one speed. Then it shuts off until the temperature rises above the thermostat’s cutoff point. Often, this indicates that the appliance needs to be operating more consistently to eliminate humidity. This is especially true when the temperature is moderate, but the humidity is high.

Consider purchasing a modulating HVAC system, such as a VRF SYSTEM, when it’s time to replace your AC system. A VRF system performs significantly better at controlling HVAC humidity because it can run longer at a reduced capacity (and provide more consistent temperatures). You’ll also see cheaper energy costs, which is an additional benefit.

The air pressure inside of you that is negative

A ventilation system that needs to be better thought out will result in negative air pressure. Simply put, it indicates that you are exhausting too much air from the area. That may occur, for instance, in a restaurant with a robust exhaust system for cooking.

The air seeks to balance itself when there is negative pressure by bringing in as much outside air as it can. For instance, a blast of wind appears to enter the room if someone opens an exterior door. Outside air is likewise pulled in through every crack and crevice in the structure.

What occurs when outdoor relative humidity reaches the 70s, 80s, or higher? You guessed it; the structure draws in that humid air. If the issue is severe enough, your air conditioning humidity control could be unable to keep up, which would impact HVAC humidity control. To fix this problem, modifications to the design of your ventilation system can be required.

You have the thermostat set incorrectly.

Using the FAN ON setting on your thermostat may lead you to believe that you are eliminating more humidity. Even when the AC is not functioning when you utilize this option, the fan operates continually.

Even when the AC is off, the fan still moves air, giving the impression that you are cooling down. But by your actions, the humidity levels are getting worse. Before it has a chance to drain away, you risk blowing the moisture that your AC has removed back into the room.

Your older device cannot take the load.

HVAC Humidity Control

Your air conditioning humidity control may not operate as efficiently as it once did as a result of parts wearing out with age. When the system hasn’t had routine maintenance, this propensity is amplified. You’ll start to notice poor HVAC humidity management in addition to irregular temperatures and insufficient cooling.

You might have to choose between repair and replacement at this stage. Is it necessary to replace the system now, or may a few adjustments be made to restore appropriate performance? Here is a resource to aid with your decision: Fix or swap out. You can attempt these steps to improve your system’s capacity to combat interior mugginess if you’re not ready to replace your air conditioner.

Clean the collis

The simplest solution to improving HVAC humidity management on an older system is to start with this. The condenser coils in your air conditioner can quickly become dirty when exposed to the humid outside air. That coating of dirt and debris hampers the unit’s capacity to dissipate heat. Because of this, the AC works less effectively and could have a more challenging time eliminating humidity from the air within.

Seek out a preventative maintenance plan

If the remainder of the system hasn’t been properly maintained, cleaning the coils alone might not be sufficient to restore efficiency and improve HVAC humidity management.

When you purchase an air conditioning humidity control preventive maintenance plan, you receive a yearly inspection, tune-up, and cleaning of the system’s components. Doing this may improve HVAC and air conditioning humidity control by keeping it operating as effectively as possible.

Additionally, your technician will be able to identify emerging issues and address them before they develop and cause the system to fail entirely.

Enhance the airflow

When humidity levels rise, a skilled HVAC technician may be able to modify the airflow in your system so that the evaporator coil becomes cooler. This may lead to more moisture removal and improved HVAC humidity management.

Only some types of AC systems can accomplish this, and there is a chance that the evaporator coil will become frozen as a result. Ask your AC expert whether this could be a solution for you.

Your system needs a dehumidifier

If everything else fails and you aren’t ready for a brand-new air conditioner, you may improve HVAC humidity management by adding a dehumidifier to your air conditioning humidity control system.

A dehumidifier removes extra moisture from the air before entering your area through your ducting. Consult a qualified HVAC expert for a dehumidifier that works with your air conditioning humidity control system.
