Why Do Air Conditioners Produce Water?
While it may seem counterintuitive for a cooling device to create moisture, this process actually plays a crucial role in ensuring your air conditioner runs efficiently and doesn’t cause any water damage in your home.
In this article, we’ll explore the science behind it and how this mechanism works to prevent leaks and optimize performance. Whether you’re a homeowner or an HVAC technician, understanding an AC unit’s inner workings can help you maintain and troubleshoot your cooling system more effectively.
Humidity in the Air
Higher temperatures and monsoons in the southwest frequently bring higher humidity during the summer months. One of the ways your air conditioner makes the air more comfortable is by removing some of this moisture, thus lowering humidity levels in your home.
How Air Conditioners Work
Air conditioners cool air through refrigeration. Inside the system are two sets of coils connected by a condenser. One of the coils is kept hot, the other cold. Chemicals inside the coils evaporate and condense repeatedly, cooling the coils. This, in turn, cools the air blowing over them. Cooled coils also force moisture out of the air; when the air condenses on the coils, it wrings liquid out the same way air condensing on a cold can of soda produces moisture on the sides.
Some of this will re-evaporate and help to keep the coils cool. The rest of it runs out of the back.
Seeing your system produce visible liquid is a good sign that the AC unit works properly. If yours is not producing visible H20, it could mean a problem — the water may be running somewhere it shouldn’t, or it may be freezing into ice on the coils.
Leaking Air Conditioners
While all air conditioners produce water as part of the cooling process, this is meant to run out of the back or a specific drain line. If the water is coming from somewhere else (e.g., pooling in your home), your air conditioner is leaking (and therefore not working properly).
Clogged Drain Lines
Your unit needs to drain most of the water it produces. If the drain line is plugged or clogged, water will collect inside, resulting in problems such as leaks from seams or other areas of the AC system. If you notice your air conditioner leaking water indoors, unplug it and take a look at the drain line. Unplug the drain line and make sure it’s clear before turning it back on.
Ice Collection
When too much is inside one, the internal fans blow the excess onto the unit’s cold coils. Over time, the coils can ice over, significantly affecting performance. When you turn it off, and the air inside heats up, the ice melts and causes a puddle to appear beneath them.
What to Do If Yours Leaks
If your A/C leaks water, fixing it can be as simple as cleaning the unit thoroughly or removing the drain line clog. However, in other cases, the help of a professional is required. Keep the following tips in mind:
1. Turn your AC unit off
If you notice your HVACs are leaking water, immediately turn it off. Turning the unit off can help ensure you can avoid damage from occurring and can help you safely determine the source of the leak.
2. Determine the source of the leak
After turning yours off, check the possible leak source. Some of the most common sources of leaks include damaged evaporator coil, dirty air filter, clogged condensate drain line, and improper unit leveling.
3. Check the condensate drain line
A condensate line clogged with debris can cause your AC system to leak. You can use a dry or wet vacuum to suction out the debris to fix the problem. You can also use a pipe cleaner to remove the blockage.
4. Check the air filter
If your AC’s air filter is dirty, it restricts airflow and causes the evaporator to freeze. When not attended to accordingly, this can lead to water leakage. Check if your air filter is dirty and replace it when necessary.
5. Check the evaporator coil for ice buildup
Your AC can also leak H20 if the evaporator coil is dirty or frozen. Check the evaporator coil for any ice or dirt buildup, and clean it thoroughly.
6. Check if the AC is leveled properly
If yours is not leveled accordingly, it can pool and leak from the unit. If your AC is not leveled properly, make the necessary adjustments.
7. Schedule a professional repair service
If any of the steps above won’t fix the AC leak, get a professional to help you. A licensed AC repair professional can easily diagnose the source of the problem and provide the best course of action to fix the problem for good.
The Dangers of HVAC Leaking
An A/C leaking may seem like a minor inconvenience, but it can seriously harm your health and home. Let’s explore the potential hazards of a leaking AC unit:
- System damage. Water leaks can cause damage to parts of your AC system, including the compressor and the electrical components. If left unattended, this can lead to costly repairs or system replacement.
- Health risks. If molds grow in the moist environment caused by the leak, they can pose health risks, including infections, allergies, and respiratory problems.
- Reduced efficiency. When you have a leaking AC unit, expect the system to be less efficient. The system has to work more to cool your home, resulting in higher energy bills.
- Electrical hazards. Electricity and liquids don’t mix well. H20 leaking from your AC unit might create dangerous electrical hazards.
