General FAQ

What about the quality and safety of your products?

Our perfumes are made using the finest cosmetic grade fragrances and pure essential oils. The propellant used in our HVAC Scenting Refills and Room Sprays is powered by Honeywell's Solstice® Propellant, which is non-flammable, non-ozone-depleting, and has an ultra-low global warming potential (GWP) of less than 1. Its GWP is 99% lower than hydrofluorocarbons (HFCs), which are commonly used in other aerosols. Solstice® Propellant is based on next-generation hydro fluoro-olefin (HFO) technology. It provides all of the performance benefits of HFCs, but with more favorable environmental properties. Our fragrances are also safe for kids and pets.

Please note: Never point the HVAC Fragrance Refills or Room Sprays towards your face. If you spray yourself, wash the area thoroughly with soap and water.

Safety Data Sheets are available upon request.

How is the shipping cost calculated in Canada?

We use Canada Post Expedited Parcel for shipping all our orders. The shipping fee is calculated directly and automatically by Canada Post and is not chosen nor determined by us. It is based primarily on where you live (we ship from Montreal, QC), as well as the quantities and weights of the products you order.

Is there a way I can save on shipping?

Unfortunately, not directly. The shipping fee is calculated directly by Canada Post and is not chosen nor determined by us. What we do sometimes recommend in order to reduce the impact of the shipping fee is to buy a few more of the same product at a time. The shipping price does not change at all or not by much if you increase the number of products (depending on the case). For example, the shipping cost should be the same whether you order one, two or three of the 50mL bottles with Dropper of Essential Oils. This means that the impact of the shipping is much less.

Do you have a store or showroom in Canada where we can try out the different fragrances and products?

While we do not have a store/showroom in Canada where you can simply show up and come to try out the different fragrances and products, we can arrange on a case by case basis for you to come see us in person if you wish. We are located in Montreal. If you would like to do this, please contact us below.

Can I pickup an order for free?

Yes, we can arrange for this manually. We are located in Montreal. If you wish to inquire about a possible free pickup of an order, please contact us first before placing your order online. We can arrange to see if one of our two pickup locations is convenient for you, and if yes we will manually create the order for you without the shipping fees. Please contact us below if you would like to do this.

Do you sell the same products as Doctor Aromas USA

Yes. The only difference is that some of the packaging formats and labelling may be different here in Canada. But all our quality fragrances and scents come directly from Doctor Aromas USA.

Why are some of the products or fragrance options I see in Doctor Aromas USA not available here in Canada? Is it possible to get them here as well?

Due to the difference in market size between the USA and Canada, we bring only the most popular fragrances and products. That being said, should you have a specific product or particular fragrance that you would like, you can contact us and we can often times especially import these for you on a case by case basis.

HVAC Scenting Systems FAQ

How do I set up my HVAC Scenting System?

Click here for a step by step.

where do I put my HVAC Scenting System once it is assembled?

It all depends of the setup of your home's (or building/store/office) HVAC setup. the idea is to ideally place it so that it hits the largest possible area of the HVAC filter. Check out our installation instructions by clicking here.

Should I use the HVAC Scent Refill as a regular room aerosol and spray it in places other than the filter of my central HVAC?

No. The contents of the HVAC Scent Refills are very different from regular room aerosol sprays. They contain plant essences and essential oils that will not "float" in the air. The mist will fall to the floor and will make it slippery. No fun ☹ Additionally, do not use the HVAC Scent Refill on furniture or fabrics since it can cause stains. Nonetheless, if you’re interested you can complement your system with our Room Sprays.

How long do the HVAC Scent Refills last? How often do I need to change the HVAC Scent Refill?

The short answer: it depends! Let us explain. An HVAC Scent Refill’s life expectancy is related to the settings at which you’ve programmed it to spray. The more you spray, the more often you’ll have to replace the refill. A full-size Scent Refill has approximately 2400 sprays. Using this aroma refill 24 hours a day, 7 days a week, with one spray every 20 minutes, it will last about 33 days. Most of our clients adapt their Scenting Systems to their lifestyles. So, some use one scent refill a month and others use one every 3 months or more.

Example of how to calculate how long an HVAC Scent Refill will last:

  1. Calculate the number of sprays per hour (e.g. if you set the dispenser to spray at 20 minute intervals, this will give you 3 sprays per hour).
  2. Multiply the number of sprays per hour by the number of hours you plan on using the fragrance refill, and you will have the number of sprays per day (e.g. if you operate the Scenting System 8 hours per day at 3 sprays per hour, then you’ll be using 24 sprays per day. If you operate the Scenting System 24 hours a day at 3 sprays per hour, you will be using 72 sprays a day).
  3. Divide 2400 (total number of sprays in each refill) by the total number of sprays per day and you’ll get the approximate number of days the canister will last (e.g. 2400 / 24 = 100 days ; 2400 / 72 = 33 days).

How do I choose the interval I need between sprays?

It’s a matter of personal preference. We suggest starting with one spray every 20 minutes. Try it for a while and increase or decrease the frequency depending on whether you feel the fragrance was too strong (make the intervals longer), or not strong enough (make the intervals shorter).

Does the HVAC Scenting System only work with central air conditioning/central forced air heating?

The HVAC scenting System only works with central HVAC (central ventilation). If you don’t have central air conditioning, fear not, we have other alternatives for you too! All our products use the same quality perfumes. Click here for more options.

Does the HVAC Scenting System work only with cold air?

Nope, the HVAC Scenting System can also be used with heat settings (which is a must here in Canada!). So, you enjoy our perfumes year-round! Do note that warm air will give you a slightly stronger fragrance.

Can I use my HVAC Scenting System in an AC wall unit or split system?

Sadly, no. The HVAC Scenting System only works with central air conditioners / forced air central heating (HVACs). Do not use it in wall units or splits. That being said, if you don’t have central HVAC, you can choose from our selection of Diffusers! These devices use the same perfumes but do not need airflow to work. Click here to see the options.

Can I use mt HVAC Scenting System with an air-exchanger?

Yes and no. Let us explain.

If you have an air-exchanger together with your HVAC machine, you can use our HVAC Scenting System, but you must make sure you install it on the HVAC portion and NOT on the air-exchanger section of your ventilation system. i.e. you must install the HVAC Scenting System in the portion of the vents AFTER the air-exchanger, not before it. Otherwise, you will just be spraying the fragrance straight outside your home instead of inside.

If you only have an air-exchanger but no actual HVAC machine, then it will not work. In this case, you can choose from our selection of Diffusers. These devices use the same perfumes but do not need airflow to work. Click here to see the options.

Is the HVAC Scenting System cost-effective?

We love this question. Yes, it is! Doctor Aromas provides results that cannot be obtained with any other system. Plugins will only deliver fragrance to the small surrounding area in which they are placed. Our System uses your HVAC to deliver the fragrance, so you will have “aromatherapy in the air” distributed evenly throughout the entirety of your home. Since you generally need only one Scent Refill, which lasts a month or more, your HVAC Scenting System also ends up being more economical than common plug-ins. To obtain similar results, you would need multiple plugins, and those scents usually have a much shorter lifespan.

What about large spaces?

If you find that you would like the fragrance intensity to be stronger, you can set it up to spray more often (which means you’ll need to replenish your Refill sooner). Alternatively, you could set up two or more HVAC Scenting Systems by the filter. However, if you have more than one HVAC unit, then you would need at least one HVAC Scenting System for each unit.

I just installed my HVAC Scenting System but it is not working.

Verify that the trigger in the dispenser is completely up before attaching the Scent Refill. If the trigger shows, push it up with the remote control or a pencil. CLICK to view our instructions. Try changing the dispenser’s batteries. Use only new AA alkaline batteries for the Mini Dispenser, D alkaline batteries for the Pro Dispenser. Use the Scent Refill and Dispenser in the upright position. It will not properly work if it is laying down or inclined. Contact us below if you are still experiencing difficulties.

Can I place the HVAC Scenting System laying down so it points to the filter when the filter is horizontal, or when placed inside a duct that is not high enough?

No. Always use your Doctor Aromas products in the upright position only. It will not work properly if it is lying down. Do not worry, even if the Scent Refill is not pointing directly at the filter, the fragrance will still be suctioned in by the airflow.

Will the HVAC Scenting System work if my central ventilation is off?

No. For the System to work, the fan must be on. We suggest you turn the fan of your central air conditioner and heating to the ON position (as opposed to AUTO) to ensure the fragrance continues to circulate throughout your home.

What is the concept behind Doctor Aromas' Scenting System?

Doctor Aromas provides aromatherapy through your central air conditioning and heating system. We aim to replicate what nature does. Let’s take flowers as an example. The essential oils in flowers can be found in their petals. When the wind blows, the aroma is lifted off the petals and it travels through the air. The scent is far-reaching and can journey through a whole field, which is why you don’t have to dig your nose into a wildflower to soak in its fragrance. The HVAC Dispenser (the scent) sprays the HVAC filter (the petal) and uses the flow of air (the wind) to scent your space. Our clients choose us because we can help them create a pleasant environment in their homes, offices, etc. You should choose us, too.
