Your Cary HVAC's number one job is to keep you comfortable regardless of the temperature outside. It's your first line of defense against the summer heat as well as the winter cold. It's also the best tool for managing humidity levels in your home. However, if you're sitting at home with the air conditioner on, but you're still uncomfortable, it's possible that your air conditioner isn't removing as much humidity as it should be. As such, today we'll discuss four key ways that you can improve the way your Cary HVAC removes humidity in your home.
1. Clean your Cary HVAC Coil
If you're finding that your air conditioner isn't removing humidity levels in your home the way it should, the first place you should check is your evaporator coil. When the indoor evaporator coil is covered in dirt and dust, it will struggle to remove all of the heat and humidity that it's designed to remove. It's also possible that the coil isn't dirty enough to prevent your air conditioner from cooling your home, but dirty enough to prevent it from removing moisture.
Luckily, the solution to a dirty coil is pretty simple. Just change or clean your air filter. As long as you regularly change your air filters, the coil should never get so dirty that it's preventing your Cary HVAC from removing humidity in the air. However, if you neglect to change your filters, dirty particles will enter your air conditioner and accumulate on the coil. If it reaches this point, you'll need to hire a professional to clean your coil.
2. Adjust the fan speed of your Cary HVAC
Typically, for hot, humid climates like ours, your air conditioner should move air at a rate of 350 CFM per ton or more. Many systems we install can move air at a much faster rate. However, when it comes to removing humidity, moving air any faster than 350 CFM per ton is not ideal.
Therefore, while a faster setting may remove enough heat from your home to satisfy your thermostat setting, it may not necessarily remove enough humidity to keep you comfortable. So, set your Cary HVAC fan speed to move at a rate of 350 CFM per ton. By doing this, the lower airflow allows the indoor coil to get colder, which removes more moisture, reduces humidity levels in your home, and satisfies your thermostat.
Alternatively, you can also use a variable speed air conditioner.
3. Check the refrigerant charge on your Cary HVAC
If the refrigerant charge on your Cary HVAC is too low, your air conditioner will have a hard time removing enough heat or humidity from your home to keep you comfortable. Left untreated, this problem could cause your coils to freeze or the compressor to fail.
4. Install a thermal expansion valve (TXV)
A thermal expansion valve, also known as a TXV, is to your Cary HVAC as a full bottle of water is to a gym rat. Having a full bottle of water means that you can work out longer without having to fill up. Same thing with a TXV. Installing a TXV helps your air conditioner remove more humidity during any given cycle by using more of the evaporator coil.
If you've already tried the steps above, installing a TXV might help your AC perform a little better. What we'll do is attach a bulb to your refrigerant line. That bulb will open and close depending on how much refrigerant is needed to maximize the working area of the indoor coil. If any of your evaporator coils weren't being used prior to the installation of a TXV, it should be better utilized after the install and should be able to manage that humidity a lot better!
All of that said, know that high levels of humidity in your home is a much more serious problem than just being uncomfortable.
