No! Not recommended to place aroma diffusers in the attic space if the temperature is not controlled. Extreme variations in temperature will cause changes in oil viscosity, which it terms affect the misting process. Hot temperatures could make the oil too liquidly and cause oil spills. Cold temperatures could make the oil too dense and not atomize at all.
Please see Connection to the HVAC system.
Please, check the connection between the plastic tube coming from the diffuser and your HVAC, the connection should be snug and properly sealed.
Our diffusers transform the fragrance oils into nano-particles that can travel effortlessly throughout the air ducts and vents without any oil residue. The aroma diffusers that come with an HVAC adaptor (brass fitting and plastic tube) can work with your HVAC system.
Connecting the aroma diffuser to your HVAC thermostat for automatic control is possible and should be done by a licensed professional only. In principle, this approach entails having a power relay switch (sold separately in Home Depot and electronic stores) being triggered by the thermostat and on/off cycle the 110V source of the aroma diffuser.
Leveraging the thermostat control for On/Off cycles ensures 100% synchronization between your HVAC and aroma diffuser and negates the need to have the air handler fan On all the time. Some companies have attempted to use the pressure switch approach, but based on our observations thermostat connection control has superior accuracy. The pressure switch approach is prone to false-positive/negative as precise pressure calibration in the air ducts is often not possible.
If you have elected for an HVAC type connection, the HVAC fan must be constantly turned on in order to dissipate the aroma particles. Not having the HVAC fan ON for a prolonged period of time can also damage your aroma diffuser.
No additional servicing is required for HVAC type connection. For optimum aroma diffuser performance please ensure proper HVAC connection, dust-free diffuser placement and timely fragrance oil refills also help.
