Air Conditioning questions, answered by experts

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
