HVAC humidity sensing fans are gaining popularity among homeowners due to their ability to maintain humidity levels for ideal comfort. To understand the pros and cons of humidity sensors, it's helpful to know what purpose humidity serves in a home.
How does Humidity control the temperature?
Humidity works with thermostats to control the indoor temperature for two main reasons:
- Moist air is more comfortable at lower temperatures, so humidity helps maintain cooler temperatures without relying on an A/C unit running constantly.
- Moisture calibrates your skin's natural moisture level, which controls evaporative cooling capabilities. This helps keep you cool during hotter months so that humidity doesn't have to be set as low for comfort purposes, making humidity used only when needed most. But how does humidity work with humidity sensors?
How do humidity sensing fans work?
HVAC humidity sensing fans can detect the humidity level in a room using electronic humidity sensing technology. This data is used by your humidity sensor-equipped fan to adjust its speeds based on your desired humidity levels.
When humidity is detected, the humidity sensor sends signals to slow down or speed up the fan's rotation, lowering humidity when needed most while maintaining optimal comfort conditions for homeowners. A humidity sensor can also help lower energy costs because it helps make sure that an A/C unit isn't running when not necessary.
It's important to note that if you're looking into purchasing a new ventilation system, they typically do not include humidity sensors. This may be one of several reasons why homeowners decide to invest in their humidity sensing fans.
There are several pros and cons to humidity sensing fans. Still, in general, humidity sensors are beneficial for homeowners because they allow for humidity levels to be adjusted when needed most, without worrying about the humidity being too high or too low when humidity isn't present.
Why are humidity sensor fans essential for your home?
Humidity must never be left at a standstill, which is why humidity sensors are often included in homes with humidity control capabilities. Many homeowners who have humidity sensor-equipped ventilation systems report improved comfort conditions within their homes after turning auto-humidity controls on. Homeowners also tend to notice less dust throughout their homes due to increased air circulation caused by humidity sensors, making it easier to keep up with home cleanliness goals.
If you're worried about humidity levels in your home, humidity sensors may be a worthwhile investment. However, humidity sensors aren't for everyone. If humidity isn't a concern within your home, you shouldn't feel the need to invest in humidity sensor-equipped fans or humidity control systems.
Things to consider when buying an exhaust fan with humidity sensor
An energy-efficient bathroom home exhaust fan with a humidity sensor can be a very smart investment. Although it may cost a bit more than a regular fan, the savings on your energy bill should pay for themselves in about a year or less. Keep these tips in mind when shopping for one, so you don't overspend on features that help you save money!
1) Size Matters
Make sure the fan is the right size for your bathroom, so it does its job without being too loud or blowing air where it's not needed. The general rule of thumb is that if you have an 8x8 ft. bathroom, get at least an 80 CFM (cubic feet per minute) fan to ventilate the space. If you have a small bathroom with a shower, make sure to get a fan designed for use in humid environments since it will be exposed to moisture from the showers.
2) Two Fans are Better Than One
Don't forget that most bathrooms require not only ventilation of the room but the removal of humidity as well. A bathroom fan helps take out some moisture from steam on hot days or from morning showers when humidity levels are high. However, they still may not meet your needs if you live in an area with lots of daily rainfall or more than 2-3 people using your bathroom regularly. In these cases, adding a separate whole house fan can help take care of any excess humidity and improve the air quality in your home.
3) Look for a home exhaust fan With a Timer and an Automatic Shut-off Feature
With a built-in timer, you can program when to turn on and off the indoor or outdoor exhaust fan, so you don't have to worry about it each time, especially if you are going away or sleeping at night when humidity levels are naturally lower. An automatic shut-off feature is also beneficial since it will turn off the fan entirely if the humidity sensor detects no moisture in the room. This prevents excessive energy use by running the fan needlessly after it has already taken care of ventilation in the room.
4) Check out CFM Ratings Before You Buy a Fan!
It's kind of like car horsepower. Although you can never really know exactly how powerful a fan is just by looking at it, you might be surprised to learn that many manufacturers exaggerate the CFM ratings on their boxes. This means you will probably not get as much power as they claim unless you are prepared to spend more money than necessary on the model with the highest rating. When comparing fans, make sure to check out actual user reviews of each model or use this helpful guide for tips on choosing an energy-efficient bathroom fan with a humidity sensor.
5) Think About Installation Before You Buy
Suppose your home has new construction and everything is already set up for wiring (most commonly in older homes). In that case, you should have no problem finding a fan that requires only simple installation, like hanging it from the ceiling or mounting it to the existing vent. However, if you are replacing an old fan with a new model with different dimensions, you will likely have to do some drywall work to fit everything inside of the wall cavity.
6) Don't Be Afraid of "Bare" Fixtures
Many people assume they have to get an exhaust fan with a humidity sensor with all kinds of venting options and other additions, but bare fixtures can also work just fine for many homeowners. Suppose you already have recessed lighting in your bathroom ceiling. In that case, installing a wire guard is usually enough ventilation without running any extra tubing back into the space above the ceiling, where it would simply affect your décor anyway!
