Connecting to the HVAC
Experience outstanding fragrance scent delivered through your central heating and cooling system. Each HVAC scent diffuser comes with a metal push-in fitting that screws into the machine and a plastic tube that connects the diffuser to the HVAC air duct.
Step 1
In order for the aroma mist to carry through the air duct, the AC must be operating or the blower fan must be turned on. If the AC (or fan) is off, the aroma mist will stay in the air duct and won’t reach the intended space. If the diffuser is operating for a prolonged period of time with the AC fan being off there will be unwanted scent buildup in air ducts and could cause diffuser or air handler damage.
Step 2
HVAC setup typically requires intensity levels 10% to 15% higher compared to standalone diffuser setup. Air duct passage creates an additional volume of space through which the aroma must travel and some capacity is lost due to the extended volume of space. With a standalone setup, the aroma covers a smaller volume of space and has a slower transit time.
Step 3
Installing the air diffuser requires adequate space to accommodate your aroma diffuser and must be close to the air ducts. The ideal placement of the diffuser tube opening is after the air handler and before the first air register (please refer to the diagram above). Please ensure the air duct opening is further away from the air handler body to prevent possible interference.
Step 4
The plastic tube that connects the diffuser with the air duct should be kept as short as possible and at the near-vertical pitch. Avoid ‘sagging’ formations in the tube as this could cause oil accumulation in the lower part of the tube and possibly damage your diffuser.
Step 5
The diffuser plastic tube entering the air duct should be approximately three to four inches inside the duct and pitched at about 10% downward angle just to ease the aroma flow.
Step 6
Ensure proper insulation of the opening by using aluminum tape and secure the plastic tube to one of the hard areas to minimize any tube movement.
Step 7
The placement of the diffuser should be in a dry, clean, moist free environment
nearby a proper 110V power outlet.

Frequently Asked Questions
Find answers about operating, installing, and maintaining your HVAC30 scent diffuser.
Using Your Diffuser
Can the HVAC30 operate internationally?
The HVAC30 may be used internationally when the local electrical supply is compatible with the voltage and frequency shown on the diffuser’s power adapter and product label.
A country-specific plug adapter may also be required. Before using the diffuser outside the United States, confirm compatibility with the local electrical standard. Do not connect the machine to an incompatible voltage supply.
How long will the HVAC30 last?
The HVAC30 is designed for long-term residential and commercial use when it is operated and maintained according to the product instructions.
Service life depends on operating frequency, fragrance intensity, environmental conditions, cleaning, and proper oil handling. Keeping the diffuser upright, using compatible fragrance oils, and performing routine maintenance will help support reliable performance.
Where do I download the mobile app?
The HVAC30 connects through Bluetooth using the Aroma Designers mobile app. Download the app from the Apple App Store or Google Play Store, enable Bluetooth on your phone, and follow the pairing instructions supplied with the diffuser.
For step-by-step assistance, visit our Bluetooth setup guide .
What is the warranty on the HVAC30?
The HVAC30 is covered according to the warranty terms in effect at the time of purchase. Warranty coverage applies to eligible manufacturing defects and does not normally cover accidental damage, misuse, unauthorized modification, incorrect installation, or damage caused by incompatible oils or electrical supplies.
Keep your order confirmation and register your diffuser after purchase. Review the current terms on our warranty registration page .
HVAC Installation
Can the HVAC30 operate as a standalone diffuser?
Yes. The HVAC30 can operate as a standalone scent diffuser using its built-in fan, or it can be connected to compatible HVAC ductwork for broader fragrance distribution throughout the space.
Standalone operation may be suitable when direct room scenting is preferred or when connecting the machine to an HVAC system is not practical.
How is the HVAC30 connected to the HVAC system?
The HVAC30 is positioned near the HVAC system and connected to the ductwork using fragrance tubing. The tube carries the atomized fragrance into the airflow so it can be distributed through the building’s existing vents.
Installation should follow the supplied instructions. A qualified HVAC professional is recommended whenever there is uncertainty about the correct duct location, airflow direction, electrical supply, or installation method.
View our HVAC connection guide for additional information.
Does the HVAC fan need to remain on?
When the HVAC30 is connected to the ductwork, the HVAC fan must be circulating air for fragrance to travel effectively through the vents and into the rooms.
The fan does not necessarily need to run continuously. For more efficient operation, coordinate the diffuser’s programmed scenting schedule with the times when the HVAC fan is operating.
Where should the HVAC30 be installed?
Install the HVAC30 upright in a dry, stable, accessible location near the HVAC system. Leave enough room to open the machine, replace the fragrance-oil bottle, inspect the tubing, and perform routine maintenance.
Avoid areas exposed to water, condensation, excessive dust, extreme temperatures, direct sunlight, or restricted ventilation. The machine should not obstruct HVAC equipment or service access.
Can the HVAC30 be installed in an attic?
An uncontrolled attic is generally not recommended when the diffuser could be exposed to excessive heat, freezing temperatures, humidity, condensation, or heavy dust.
When the HVAC equipment is located in an attic, place the HVAC30 in a protected and accessible area that remains within the operating conditions stated in the product instructions. Consult an HVAC professional when the installation environment is uncertain.
Can connecting the HVAC30 damage the HVAC system?
The HVAC30 is designed to work with compatible HVAC systems when it is installed correctly and operated according to the supplied instructions.
Incorrect placement, unsuitable tubing installation, improper electrical connections, excessive fragrance output, or unauthorized modifications may cause problems. Professional installation is recommended whenever there is uncertainty about the system or ductwork.
