The Flow Penetrates The Vents On The Floor

This is a discussion on ac only blows out into floor within the external engine forums part of the lsx technical help section category.

The flow penetrates the vents on the floor.

Below are a few hvac vent system considerations and placement recommendations. Erol very strange as i just had a slab inspection last week with the same exact problem. Either every room with a supply register will also have a return air vent or there can be centrally located return vents on each floor of your home. I have spent 2 full days trying to fix it myself but with no look.

These vents will facilitate cross flow ventilation below the joists. These vents must be enclosed to prevent air getting into the cavity of block wall construction. Based upon your geographic location will heating or cooling needs prevail. If the vents are too close together this can cause the air to slip away without impacting the room temperature.

The heat then rises and continues to warm the rest of the room. In geographic locations where heating needs predominate however the story changes putting floor vents in the spotlight. I have checked the fuses under the dash passenger side far right next to kick panel and they are okay. I went and pulled the cover off a return vent because i was just curious as to why the return vents were installed on outside walls in the living room and viola 3 inches of standing water in both return vents in this room.

Often these vents can be blocked restricting the amount of ventilation being achieved. Since the goal of return vents is to get the air back to your heating and cooling units height can be flexible. Floor vents are typically used in homes where the furnace is in a basement or the ducts the piping from the furnace travel through an underground crawlspace. My air conditioning is blowing cold air but it directs the flow to the windshield and floor and not from the vents in the dash.

Figure 1 floor ventilation overview. Floor ducts are effective because they deliver heated air at floor level. The vents wont change from floor to any other position the knob twist but no effect and the a c and recirc air buttons don t engage or light up. My ac will not blow through the vents only comes out in the floor.

Return air vent installation. Doesn t waste usable space ceiling ducts don t hog existing or potential closet wall or ceiling space making an interesting or worse unsightly decoration and ceiling vents don t present the decorative dilemma. In the natural pattern of air flow cool air sinks and hot air rises so best practices must consider the primary role of your system. Ac only blows out into floor.

As a general rule ceiling mounted vents offer better cooling potential while floor vents offer superior heat delivery. It blows cold air though. Proper placement of vents.
