4 Reasons Why Return Vent Is Better Than Supply Vent
An HVAC system is designed to remove excess moisture and humidity from the air in a building, especially in the warmer months. A supply fan draws air from a building and then forces it back outside, which works well in the winter months when the air is dry.
When summer arrives, an HVAC unit should do three things: cooling, dehumidifying the air and keeping insects out. A return fan can do all three things with one device, a supply fan cannot.
The result of the inefficiency of the supply opening is that there is insufficient dehumidification, often leading to mold and mildew problems in warmer climates. The result is an HVAC system that has to work harder to keep the air in a building fresh.
Keep reading to discover more reasons why return fans are better than supply vents.
1. Return vents allow air to circulate at all times
An HVAC system with a return air grille keeps the air in a building circulating at all times, which is an important feature for both psychological and health reasons. While an HVAC system with supply fans can do this, a return fan is more efficient and effective.
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 using (and paying for) an HVAC system most of the time. In addition to being good for people’s sense of smell, cold air and odors tend to float to the ceiling, where they can be sucked out by a return fan.
A supply fan does not have this option (you need separate odor eliminators and dehumidifiers in addition to your supply opening). There is less chance of spreading diseases and ailments (as explained in the research into sick building syndrome).
2. Return vents probably come with a better warranty
A well-designed return fan will last up to 30 years. In comparison, a supply vent can only be used for about 15 years before you need to replace it (and possibly more time if your building is in an area where temperatures fluctuate widely).
Therefore, a return breather is more likely to come with a warranty that will cover the replacement if something happens to it. Your supply vent will be yours anyway — and there’s also the chance it won’t even last as long as advertised.
3. Returns are more affordable
Supply fans cost about $200 more on average than a return fan (maybe more depending on your location). But that doesn’t mean the feed opening is more effective. Not only will you save money in the long run, but you’ll likely get a better warranty with a return vent and save on energy costs. Ultimately, return fans last longer than supply vents, while offering a better warranty and less cost to run. What more could you ask for?
4. Return vents work with all HVAC systems
You don’t have to worry about your return vent not matching a particular type of HVAC unit. A return vent is compatible with all types, so you won’t have to worry about getting one when the time comes.
Return vents allow you to continue using your existing system (if it is working properly) while enjoying a more efficient ventilation system. If you’re looking for a new HVAC system, only consider those with reliable return fans – even if they cost a little more up front. You will save money in the long run when it comes to repairs and energy costs.
Can I install vents in my old house?
How you HVAC system is designed determines whether a supply or return port is used. If you’re remodeling, you’re more likely 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 openings are usually already where they should be when the building was built.
However, if you’re adding or moving into a building with an existing HVAC system, chances are it won’t have vents, meaning your air quality could suffer until you can fix it.
