In this article, we’ll cover the 7 reasons why an A/C unit leaks water and what you can do about it to fix it. Let’s dive in! How A/C units work (and leak water) Air conditioners leak water for a few reasons. With an A/C unit, as warm air blows over a series of coils inside the unit, the coils transfer the air to various parts inside and outside of the A/C unit. During this process, condensation can appear (think: water drops on a cold glass of water on a hot day). As a result, water drops can form in, around, and outside of an A/C unit, and voila! An A/C unit starts to leak water. The good news is that most times, fixing an A/C that’s leaking water is easy. 7 common causes on why A/C units leak water The seven most common reasons an A/C unit may leak water include damage or issues with the following components: We’ll describe each of these in detail in the following sections. 1. A frozen evaporator coil One of the most common causes of an A/C unit leaking water is when an evaporator coil freezes. The reason an evaporator coil freezes is because an air filter is dirty or issues exist with airflow blowing over the coils. If a coil doesn’t have enough warm air contacting the coils, ice forms. The good news is that fixing a frozen evaporator coil is possible. To fix a frozen evaporator coil: If the coils haven’t thawed after trying the above three suggestions, we recommend giving a Florida HVAC repair team a call. They’ll have the tools and knowledge to resolve your issues before said issues become emergencies. 2. Damaged condenser Also known as the outdoor A/C unit, the condenser helps release the heat from the indoor unit in the house. A damaged condenser can cause an A/C system to leak water. If you notice cracks in the housing of or coolant leaking from your A/C unit, you may have a damaged condenser on your hands. To fix a damaged condenser, you can replace the gasket or sealant. But, if the issue becomes more severe, you may have to replace the condenser itself. If you need your A/C up and running fast, we recommend reaching out to an HVAC and/or cooling repair team for immediate support. 3. Thermostat malfunctions (and more) A malfunctioning thermostat also can cause an A/C to leak water. As we mentioned in the section above, if the evaporator coils become colder than their optimal temperature, the coils can freeze. To fix a broken or malfunctioning thermostat, try the following simple solutions: If the above solutions don’t fix your air conditioning leak, call an HVAC technician to troubleshoot the problem. An HVAC technician can help you determine the best course of action to prevent future issues with your air conditioning unit’s thermostat. 4. A/C unit is leaking refrigerant fluid Another reason an A/C unit might leak water is because of refrigerant fluid. Refrigerant fluid can cause leakages if an HVAC unit doesn’t have enough refrigerant in its system. Your air conditioning system might have a refrigerant leak if you notice any of the following: We’d be failing you as HVAC technicians if we didn’t mention that refrigerant leaks are dangerous. If you have low refrigerant fluid or notice refrigerant leaks, have an HVAC technician inspect your entire unit. If you need to call a technician for emergency support, don’t hesitate to reach out to us for immediate emergency air conditioning repairs. We’ll make sure your unit is up and running in no time. 5. Clogged condensate lines could be the culprit If you think condensate lines have something to do with condensation, you’re right. Condensate lines carry water and excess moisture buildup from the drain pan inside a home to the outside of a home. If you have clogged condensate lines, water can back up and leak out of the drain pan. To fix a clogged condensate line, consider the following solutions: If you find the blockage persists, it’s best to call a professional. An HVAC professional has the knowledge, tools, and training to resolve clogged condensate lines with skill and ease. 6. Broken condensate pumps (and float switches) If your air conditioner is leaking water, the issue could be with the condensate pumps. A condensate pump helps ensure water is pumped outside of the home. If the pump breaks, you’ll need to replace it to prevent water build-up in the home. The solution is as simple as that. 7. Leaky or damaged drain pans We saved one of the most important reasons for an A/C leaking for last. A drain pan collects the water that drips off the evaporator coils as the coils cool the air blown across them. If you have a cracked or damaged drain pan, the pan can leak water on the floor. To fix a leaky drain pan, try the following: Streamlined pro tip When considering replacing parts of your HVAC system, you’ll want to seek out the advice of a professional.

A/C Not Blowing Cold Air? Here’s 10 Reasons Why (& How to Fix It)

A man working on an A/C unit that isn't blowing cold air

You’re on your way home on a hot summer day, and you’re counting the minutes until you enter that cool wave of delicious air conditioning air in your home. You enter your home and think, “My AC is not blowing cold air. What gives?!” But you’re home now, and your AC unit isn’t blowing cold air. Not quite the relaxed welcome you were looking forward to, huh? Streamline Air here: we can’t tell you how many times we’ve been in your shoes. There’s nothing worse than feeling sticky, uncomfortable, and sweaty due to an A/C unit not blowing cold air. Good news: we’ve got what you need to get your system back in action again. For more than 20 years, we’ve been providing homeowners and businesses with quality HVAC repairs and troubleshooting for all their air conditioning system needs. If your air conditioner isn’t blowing cold air, your AC unit is likely having issues with one of its lines, pumps, or more. Don’t sweat it, though. In this article, we’ll describe the top 10 most common reasons why an A/C unit isn’t blowing cold air — and what you can do to fix it. Let’s dive in. Table: 10 Common reasons why an A/C unit isn’t blowing cold air Reasons why cold air isn’t blowing through an A/C unit 1. Your thermostat settings are off2. You have refrigerant leaks3. Your evaporator coils might need cleaning4. Your air filters may be dirty or need replacing5. Your compressor might need repairs6. Parts of your A/C unit might be clogged7. You may have leaks in the air ducts8. You might be experiencing issues with the circuit breakers9. You might have damaged fan blades10. Your A/C unit may be old and need to be replaced 1. Your thermostat settings are off A faulty thermostat can cause your AC not to blow cold air. Blocked vents in the thermostat controls can also cause an A/C unit not to blow cold air. No obstructions should prevent airflow around your A/C unit. What’s more, we recommend checking your owner’s manual for guidance on replacing batteries and adjusting settings in your thermostat. If the settings aren’t the issue, consider replacing the thermostat. A smart thermostat upgrade can give you an accurate temperature reading and help with troubleshooting future thermostat-related issues. 2. You may have a refrigerant leak If the thermostat isn’t the issue, you can also check for refrigerant leaks. Low refrigerant levels can make cooling your home a challenge for your A/C system. Your A/C system has to work harder, all of which could saddle you with higher energy bills and potential health complications. A note of caution: refrigerant leaks should always be diagnosed and fixed by a trained professional.An HVAC technician has the tools and knowledge needed to keep you safe and healthy. For example, your technician will measure the refrigerant with specialized tools like a multimeter.With the support of a professional, you’ll be in good hands with any refrigerant leak that could pop up. 3. Your evaporator coils might need cleaning One of the largest issues of HVAC units blowing warm or hot air comes from evaporator coils. Frozen or dirty evaporator coils can cause your air conditioner to stop blowing cold air. Ice can build up around the coils and block normal airflow. When ice builds up, your air conditioner has to work extra to cool the incoming air. As dust and dirt collects on these coils, ice is more likely to form. And ice affects the airflow around the unit. You can help troubleshoot your evaporator coils with regular visual inspections. To troubleshoot your evaporator coils, switch off the unit and inspect the coils for grime or frost. You can clean the coils using a vacuum cleaner with a brush attachment — or if you prefer — call a professional for quick and comprehensive coil-cleaning service.  4. Your air filters might be dirty (and need replacement) Dirty air filters: they can make your AC stop blowing cold air. Air filters catch dust and debris, which helps you stay cool and relaxed. But, over time, they clog up. When clogged, air filters block airflow and make your A/C unit work harder. The result? A system that doesn’t work properly — and higher utility bills (ouch). To keep your air conditioning system running smoothly, we recommend changing your dirty filters each month. Doing so will ensure you have cleaner indoor air and help you avoid the need for costly repairs. 5. You have a compressor that needs repair work Think of a heart. Its function is to pump blood into your body. The compressor is like the heart of your air conditioner, as it pumps refrigerant through the system. If the compressor fails, no cold air will come out of your A/C unit. Dirty outdoor compressor coils can cause an A/C unit to work harder and thereby overheat. You can ensure your compressor functions well by conducting a visual inspection of your A/C unit. What’s more, you’ll also want to check the capacitor for any ruptures or bulging, as these signs indicate damage to a compressor. As always, regular maintenance checks can help you avoid unexpected failures in central air conditioning systems or mini split air conditioning systems. If you notice any moisture around your A/C system — or if your A/C shakes or makes any unusual noises — reach out to an air conditioner repairman for comprehensive support with your compressor. 6. Your A/C unit is clogged A clogged drain line can stop an AC unit from cooling. Clogs occur when the condensate drainpipe becomes blocked with dirt or mold.  As a result, water backs up and triggers a safety switch that shuts down the system. Unclogging drain lines is crucial for proper A/C functioning. You can ensure your drain lines stay clean by cleaning and replacing clogged drains often. You might need to use a wet-dry vacuum cleaner to clear out the debris, but doing so pays off. Keeping your A/C unit
