HVAC stands for "heating, ventilation, and air conditioning." That said, there are several common problems that result from not ventilating your bathroom properly. If you have no bathroom ventilation at all, then you have even bigger problems. Your bathroom vents should air straight out the top of the roof of your house. Otherwise, you will end up with the following problems:
Far Too Much Moisture in the Attic
Too much moisture in the attic leads to mold and mildew. The mold and mildew lead to rotten boards and decay. The decay leads to ceilings collapsing inward and incredibly expensive repair bills. Worst of all, you would not see this coming until the rot is so bad that the bathroom ceilings begin to show it. Moisture in your attic needs to be controlled, and the best way to do that is to completely vent all the hot and humid air from your bathroom.
When things begin to decay in the attic, and the warm, moist air continues, you are sending an invitation out to moisture-loving pests. You are already familiar with some of these pests; silverfish, centipedes, millipedes, and cockroaches. Additionally, some types of flies love to lay their eggs in moist, wet areas that are starting to decay, which means that you could have all kinds of wriggly larvae squirming around on attic beams and your insulation.
Heavy Condensation on Attic Windows
Foggy attic windows are not very attractive. Besides signaling that there is too much heat and humidity going directly into the attic and not out the roof, these fogged-up windows also make your home look a little unkempt. You could go into the attic and wipe away the condensation, but as long as the bathrooms do not vent to the outside, you may as well sit in the attic 24/7 wiping away the fog from the attic windows.
Get an HVAC Specialist's Help
It is quite surprising, but reconfiguring and installing new bathroom vents that go through the roof do not take that much time at all. If you already have vents for the bathrooms in your home, the HVAC specialist only has to extend the vents through portals in the roof. If you do not have any bathroom vents at all, it may take a little extra time, but generally, the new vents are installed within an hour, give or take about fifteen minutes.Share
