Dealing With Excessive Moisture Before It Gets Out of Hand
You’re settling down to enjoy the nice cool breeze produced by your HVAC system. Suddenly, you hear a dripping noise, and a sneaking suspicion starts nagging at you. You get up to check out the HVAC unit only to discover that the once-pristine floor below is totally drenched.
Where did all the water come from? More importantly, how can you get rid of it? The answers may lie in diagnosing the problems with your HVAC appliance. Here are a few tips that might shed some light on the issue.
Check the Condensate Line
According to Popular Mechanics, backed-up condensate lines are the most common causes of AC leaks. These appliances use refrigeration cycles to cool down your surroundings by removing moisture from the air. The condensate line is supposed to direct this excess to an appropriate drainage location. If the line gets clogged, then the water might not have anywhere to go and end up leaking onto the floor.
Dealing with condensate line blockages is usually a fairly straightforward fix. In most cases, you can correct the issue with a simple cleaning, although it’s usually best to have a professional perform this procedure.
Check the Coil
Before the excessive moisture from the air can drain through the condensate line, it has to condense on a coil. This process works best when things are clean: Dirt can interfere with the water’s ability to bond to the coil surfaces. If this occurs, it can drip and overflow onto the ground before the condensate line can carry it away.
Although fixing this kind of problem also requires thorough HVAC cleaning, it’s even more essential to get a professional to handle the maintenance. Opening up an HVAC system to get at the evaporator coil can expose you to high voltages and dangerous mechanical parts. This is definitely a job best left to the experts.
Check the Installation
Seemingly minor installation errors can cause big problems down the line. For instance, the condensate pipes leading away from your HVAC system’s coils may have been fitted together improperly. Or, the entire unit might have been installed at a slight angle, preventing the drip pan from holding as much water as it should without spilling over. Incorrect setups can also be particularly problematic because they might lead to other problems.
It’s not always easy to diagnose an improper installation since their symptoms vary widely. For instance, an improperly placed sensor might prevent the HVAC unit from turning off automatically when it should have detected a potential overflow condition. Modern systems with advanced control functions require even more fine-tuning and operating precision.
Stopping an HVAC leak is much easier when you know exactly why it occurred. For more handy insights on keeping your system in proper working order, check out our other smart tips online.
