Improve Your RV’s Ventilation

It’s vital to make sure that your RV is at all times well-ventilated as this allows the continuous flow of fresh air.

The best way you can make this happen is by closing the windows on the warmer or sunny side to prevent the entry of warm air.

It would also help if you then opened the windows on the shaded side, and this will considerably help to improve the air circulation in your RV.

Another thing you need to consider doing is installing a ceiling vent inside your RV. This gadget does an excellent job of ensuring the continuous flow of air inside, making it a more habitable.

Clean the Filters

Air filters need cleaning from time to time since they over time start experiencing difficulty passing fresh air through the vent.

The issue in such a scenario may be clogged vents or filters or blocked openings. Normally, filters are installed in different positions on different RV models with some found along with the ceiling where you’d need to remove other vents or fastened to the unit where dials are positioned sideways.

Nevertheless, the steps to follow when cleaning the filters are the same regardless whether the filters are linked or detached from the unit.

All you’re required to do is taking out the grill which may or may not come with screws and shaking out the debris. You can also soak the filter in warm soapy water, rinse it and then allow it to dry before reinstalling it inside the vent.

By regularly doing this, you’ll be able to improve the airflow inside your RV as well as the quality of air.

As a result, you’ll have a much easier time regulating temperatures inside your RV and prolonging the filter’s lifespan.

Furthermore, this helps save energy since the system won’t be needed to work tirelessly while still ensuring airflow inside the RV is at its ideal setting.

Use LED Light Bulbs

Another way of increasing airflow inside your RV is by using LED light bulbs instead of incandescent light bulbs which produce too much heat.

Therefore, this can be quite uncomfortable, especially when taking trips during the summer as your RV’s interior becomes very hot. It would thus be best if you instead opted for the more energy-efficient LED light bulbs.

With these bulbs installed, you’ll be able to improve the airflow in the RV since less energy and heat are being produced while still ensuring there is sufficient light inside the RV.

Make Sure Air Keeps Circulating

For the travel trailer’s side, that is under direct sunlight, and you can use a sun reflector to prevent the entry of sunlight inside your travel trailer.

You can also improve air circulation inside your RV by positioning your car such that its ceiling fans aren’t taking in fresh air rather than hot air.

This is a mistake often done by most RV owners who then switch on the fans making the rig’s interior uncomfortably hot.

Keep Out the Sun

One proactive measure you should take to improve your RV’s airflow is by keeping out the heat from your RV.

This helps ensure the air that is finding its way inside your RV isn’t warm as this would affect air circulation. You should thus make sure always to implement these two steps or else risk too much heat finding its way into your travel trailer.
