Humidity Effect on Air Conditioner – How to Deal with It

When you experience excessive humidity in your home, it can have your room feel even hotter during the summer season. But the humidity levels don’t only affect your comfort, but your air conditioner as well.

When humidity levels get too high, it would negatively affect your air conditioner’s cooling efficiency. So how can you deal with that?

Read on as I talk about the effects of humidity on air conditioning units and how you can deal with it better.

The Effects of Humidity on Air Conditioners

When you have an air conditioner that works efficiently, it removes adequate amounts of heat and moisture from the room, which results in a comfortable environment. If not, then your air conditioner won’t be able to achieve the desired comfort level in a room, no matter what temperature you set it on.

When humidity levels are high, your air conditioner will need to work even harder to maintain a cool room. If you have an old model or an inefficient unit, or the one with the wrong size, then it may not handle the job of cooling your room. As a result, your home can feel even warmer than usual since the air holds extra moisture that can’t be removed properly.

Besides this, your air conditioner will need to work even longer and harder without giving you the cool room you expected. This would wear your unit out while increasing your energy use and utility bills.

Is the solution to get a larger air conditioner? Not always.

You need to make sure that you have a properly-sized system for your room, which depends on the room you plan to place the unit in. In fact, an oversized air conditioning system can worsen the humidity issue in your home!

A professional can help you figure out what size you need.

What about those using a central air conditioning system? If it isn’t cooling your room well, then it may be due to excess moisture in the area. Here are a few signs that you are experiencing high humidity or moisture levels:

  • The air in the room feels moist
  • The windows are foggy
  • You see damp parts or smell musty scents around the house
  • If your skin feels clammy and moisty

If you notice any of these, then there is too much humidity and it’s time to take action, for you, your air conditioner, and your home’s sake.

How to Deal with Humidity Effects on Your Air Conditioner

Now that you know what happens to your air conditioner if humidity levels increase, what can you do about it?

The obvious answer here is to dehumidify your home. Here are ways you can do so:

  1. Install a Dehumidifier

This is one of the best solutions, especially when humidity levels are high during the summer season. Your air conditioner may come with a dehumidifying setting.

However, if low humidity levels are the problem, then you can invest in a humidifier. Both of these appliances can be installed beside or with your system to improve its performance.

Maintain indoor humidity levels between 30-40% during the winter, keeping the room temperature around 71-77 degrees Fahrenheit. If it is summer, maintain a humidity level below 60%. This all depends on the outdoor temperature, though.

To measure your humidity levels accurately, you require a hygrometer, thermometer with humidity readings, or a smart thermostat.

  1. Invest in a New Air Conditioner

If push comes to shove and the room doesn’t cool down as efficiently as it used to before, then it may be time to change your air conditioner to a modern model, or something more suitable to your home.

If your cooling device is larger than what is required, it can’t run for longer periods, so it cannot remove excess moisture. The same goes for older air conditioners that have lived their lifespan.

However, if you can’t change your air conditioner just yet, or if you already have a new one, I suggest that you turn the thermostat down to a lower setting, which has your home comfier and drier. However, this is only a short-term solution, which is why a de/humidifier or new air conditioner can work best.

Another thing you can invest in is an air filter or UV filter, which is useful in capturing dust, dirt, air particles, along with killing viruses and bacteria. They can kill off radon gas or mold spores, which may affect the humidity levels. Adding ventilation around the house, especially in the kitchen and bathrooms, will help control humidity and bring in fresh hair, cycling out the stale and dusty air.

  1. Regular Maintenance

For those with new and working air conditioner units, be sure to maintain them well, cleaning them regularly, and scheduling maintenance with the right professionals. You can prevent dust buildup that causes poor performance on your air conditioner and high humidity levels in the room by cleaning and monitoring the way your air conditioner works.

Be sure to clean the ducts, your air conditioner, and outdoor equipment.

Furthermore, a checkup by a professional can help identify any issues or potential issues that can be solved and prevented immediately before it worsens. This avoids damage and hefty costs, both in your wallet and overall comfort.

Wrapping It Up

Hopefully, you learned a lot about humidity and air conditioners! If you experience poor humidity levels at home, use these tips and improve your home’s overall comfort now. Good luck!
