Having control over the comfort in your home is very important. While there are many ways to manage indoor comfort levels, there are two devices in particular that play critical roles- Thermostats and Humidistats.



According to Bryant®, a thermostat is defined as "a unit that monitors and controls your HVAC system products". Thermostats are essentially the brain of every heating and cooling system, as it is typically the main control system for your HVAC unit. Not only do thermostats control turning your heating and cooling system on and off, but they also help maintain and control the desired temperature level in your home. A programmable thermostat is one type of thermostat that is designed to adjust and change the temperature in your home according to a series of programmed settings that take effect throughout the day at different time intervals. Programmable thermostats are a more energy efficienct solution to help regulate temperatures in your home. For additional information, please visit our blog post on programmable thermostats here.


According to Bryant®, a humidistat is defined as "a control used to manually maintain humidity at a fixed point". Humidistats automatically adjust the amount of moisture in the air to help maintain a set humidity level throughout the house. When humidity levels are not properly maintained, it can have adverse effects on your family and overall comfort. Indoor air that is too damp can make your skin feel sticky. It also makes your home more susceptible to mold and mildew, which can not only cause damage to your furniture (especially wood furniture) but also can be detrimental to your health. Conversely, indoor air that is too dry can make your skin dry out and can trigger asthma and other respiratory issues. It can also crack or split your furniture (especially wood furniture). Lastly, improper humidity levels can have a direct effect on your utility bills, as low humidity levels make your home's indoor air feel cooler which can cause you to turn up the temperature while high humidity levels make your home's indoor air appear to be warmer which can cause you to turn down the temperature.
