HVAC Repair: What Causes Leaks in HVAC Systems?

HVAC Repair What Causes Leaks in HVAC Systems 1

A lot of effort goes into maintaining an air conditioning system. Simple issues that require HVAC repair are actually easy to miss, which could create more serious problems if not attended to. As a responsible homeowner, you need to understand how the system works. It’s important to know how to prevent those small leaks to prevent bigger leaks from happening ever again.

Below are the most common causes of HVAC leaks that you need to take note of.

1. Disconnected Drain Line

AC units that are not installed properly may result in unsecured fittings. They can loosen over time, which results in the drain pipe disconnecting from the AC unit. This means the condensate will drain through your ceiling or even onto the floor.

Similar to a clogged drain line, where your leak will end up depends on which drain pipe is affected. It is also based on whether your AC is located in your house or in the attic.

2. Condensate Pump Issue

If your condensate pump is dirty or malfunctioning, it could lead to a water leak from your AC unit. What’s worse is the leak could flood your entire basement or attic if left unfixed. Because there is a constant flow of water, mold and mildew can grow inside and around your unit, which increases the possibility of a serious clog. This is a problem that only your trusted HVAC repair technician can address.

3. Clogged Drain Line

This is considered as one of the most common causes of water leakage from the unit. As summer temperatures rise, more service calls are made to HVAC professionals regarding this problem. It’s also worth noting that drain lines can be clogged with algae, rust, dirt, and other kinds of debris.

4. Dirty Coil

An evaporator coil can malfunction if it’s not routinely cleaned. Once a coil gets covered in dirt, mold, or dust, the water is not bonded to its surface as tightly as before and will drip directly to the ground. With a dirty coil, you can experience problems concerning the water drain. Any dirt from the coils will be carried through the system and is likely to cause clogged drains. This means the water has nowhere else to go other than back to your home.

Notice Any Leaks from Your AC?

If you start to see leaks coming from your AC system, we suggest you call for professional help ASAP. The HVAC repair technicians will inspect your unit and determine whether the leak is water or refrigerant. They will then advise you on the best course of action for your HVAC system.

Not only will your technician be able to identify the source of the problem, but they will also be able to pinpoint other small issues that could be affecting your AC. Regular maintenance visits are advised to all AC owners to ensure that your coils, central humidifiers, and furnace stay clean and functional all year round.
