An HVAC system aims to remove excess moisture and humidity from the air inside a building, particularly in the warmer months. A supply ventilator sucks air from inside a building and then forces it back outside, which works well for winter months when the air is arid.
When summer comes around, an HVAC unit needs to provide three things: cooling, dehumidifying the air and keeping out insects. A return ventilator can accomplish all three things with one device, while a supply ventilator cannot.
The result of the inefficiency of the supply vent is that there isn’t enough dehumidifying action going on – many times leading to mould and mildew problems in warmer climates. The result is an HVAC system that needs to work harder to keep the air in a building fresh.
Keep reading to find out more reasons why return ventilators are better than supply vents.
1. Return Vents Keep Air Circulating at All Times
An HVAC system with a return air grille keeps the air inside a building circulating at all times, which is an important feature to have for both psychological and health reasons. While an HVAC system with supply ventilators can do this, a return ventilator is more efficient and effective in doing so.
Psychologically, people’s perception of how good the air in their building smells and feels changes when there’s constant airflow – even if that means running an HVAC system most of the time (and paying for it). In addition to being good for people’s sense of smell, cold air and odours tend to waft up to the ceiling, where they can be sucked away by a return ventilator.
A supply ventilator does not have this capability (you’ll need separate odour remover and dehumidifier devices in addition to your supply vent). There’s less chance for sickness and disease to spread (as explained in the sick building syndrome study).
2. Return Vents Likely Come with Better Warranty
A well-designed return ventilator will last up to 30 years. In comparison, a supply vent can only accomplish about 15 years of use before you have to replace it (and possibly more time if your building is located in an area where the temperature fluctuates widely).
Therefore, a return vent is more likely to come with a warranty that covers its replacement if something happens to it. Your supply vent will be on you no matter what – and there’s also the chance that it won’t even last as long as advertised.
3. Return Vents Are More Affordable
Supply ventilators cost more than a return ventilator by about $200 on average (perhaps more depending upon your location). But that doesn’t mean the supply vent is more effective. Not only will you save money in the long run, but you’re also likely to get a better warranty with a return vent and save on energy costs. In the end, return ventilators last longer than supply vents while providing a better warranty and cost less to operate. What else could you ask for?
4. Return Vents Work with All HVAC Systems
There’s no need to worry that your return vent will not fit in with a specific type of HVAC unit. A return vent is compatible with all kinds, so there’s nothing to worry about in terms of getting one if the time comes.
Return vents allow you to continue using your existing system (if it’s working well) and enjoy a more efficient ventilation system at the same time. If you’re looking for a new HVAC system, consider only those with reliable return ventilators – even if they cost slightly more upfront. You’ll save money down the line when it comes to repairs and energy costs.
Can I install Return Vents to My Old House?
How your HVAC system is designed will determine whether it uses a supply vent or return vent. If you’re remodelling, you have more of a chance to design something with a return vent because an HVAC unit can be placed anywhere in the building (as long as there’s access to electricity and water). Supply vents are usually already where they need to be when the building was constructed.
However, if you’re adding on or moving into a building with an existing HVAC system, the chances are good that it doesn’t have return vents, which means your air quality could suffer until you can get it fixed.
The Bottom Line
The return ventilator is a better choice than the supply ventilator because it provides more efficiency, effectiveness, and affordability. If you consider installing an HVAC system in your building or have already done so, we recommend that you opt for the return vent instead of the supply vent. This ensures maximum comfort and health benefits for everyone inside.
