AC Repair

Why is my AC not working? It’s a question no one wants to ask especially during a heatwave. Few things are more frustrating than an air conditioning unit not working when you need it most. Whether it’s blowing warm air, not turning on, or making strange noises, an AC not functioning properly can quickly disrupt your comfort and routine. Identifying the root cause early can save you time, money, and stress. In this guide, we’ll break down the most common problems, share practical troubleshooting tips, and help you understand when it’s time to call in a professional. Why Is My Air Conditioner Not Cooling the House? Is your AC not functioning like it used to? If your air conditioner stopped working or isn’t cooling your home properly, there could be several reasons behind it. Before calling a technician, there are a few things you can check yourself. Here are some common causes and what they might mean for your system. Dirty or Clogged Air Filters One of the most common reasons for poor cooling is dirty or clogged air filters. When the filters are blocked, airflow is restricted, causing your system to work harder and cool less effectively. Check your filters and replace them if they appear dirty or haven’t been changed in a while. Thermostat Settings It might sound simple, but incorrect thermostat settings can lead to your air conditioner not functioning correctly. Make sure your thermostat is set to “cool” and the temperature is set lower than the current room temperature. Also, ensure it hasn’t accidentally been switched to fan-only mode. Refrigerant Leaks If your AC system has refrigerant leaks, it won’t be able to cool your home properly. Low refrigerant levels can reduce efficiency and may even damage your system. This issue typically requires a professional AC repair to diagnose and fix the leak to restore your system’s performance. Frozen Evaporator Coils Frozen evaporator coils can also prevent your AC from cooling effectively. This usually happens when there’s insufficient airflow due to a dirty filter, blocked vents, or low refrigerant. If you notice ice buildup on the indoor unit, turn off the system and let it thaw before restarting. DIY Checks Before Calling a Technician Before calling for service, here are a few things you can try: These simple steps might get your air conditioner functioning again without the need for professional help. When Poor Cooling Is a Serious Issue If your AC is still not cooling after basic checks, it could be a sign of a more serious problem such as compressor failure, a faulty capacitor, or electrical issues. In this case, it’s best to call a qualified HVAC technician to inspect your system. You may read How Long Do AC Units Last? Why Doesn’t My Air Conditioner Fan Work? If your AC is not functioning properly and you’ve noticed that the air conditioner fan isn’t working, it’s important to understand what might be causing the issue. There are two key fans in most air conditioning systems, and problems with either can lead to poor cooling or system failure. Blower Fan vs. Condenser Fan Understanding the difference between these two fans can help pinpoint the problem: Common Reasons the AC Fan Isn’t Working Here are a few common causes to consider if your air conditioner stopped working or the fan isn’t spinning: 1. Tripped Breakers A tripped circuit breaker is one of the simplest causes. If the breaker connected to your AC has tripped, the fan won’t run. Check your electrical panel and reset the breaker if needed. If it trips again, there may be a deeper electrical issue. 2. Faulty Fan Motor A faulty fan motor can prevent the fan from spinning entirely. Over time, motors can burn out due to wear and tear, overheating, or lack of maintenance. If the fan hums but doesn’t move, or turns slowly, the motor may be the problem. 3. Capacitor Issues The capacitor helps the fan motor start and keep running. If it fails, the fan may not spin at all. Signs of capacitor issues include a humming noise without fan movement or intermittent operation. 4. Thermostat or Control Board Malfunctions A faulty thermostat or control board can send the wrong signals to the system, causing the fan not to activate when it should. Try setting the thermostat to a cooler temperature or switching it to “fan-only” mode to test responsiveness. How to Tell If the Fan Motor Is Burned Out Here are some signs that your fan motor may be burned out: If these symptoms are present, it’s likely time to replace the motor—something best handled by a qualified HVAC technician. My Air Conditioner Isn’t Turning Off If your AC does not work as expected and keeps running constantly—even when the temperature is already cool this could signal a deeper problem. While your air conditioner should cycle on and off to maintain the desired temperature, continuous operation can waste energy, strain the system, and indicate something is wrong. Here are some of the most common reasons why your air conditioner isn’t turning off, along with what to look out for. Faulty Thermostat A faulty thermostat may fail to signal your system to stop once the set temperature is reached. It might be: Try replacing the batteries or resetting the thermostat. If that doesn’t help, the thermostat might need to be repaired or replaced. Stuck Contactor Relay Inside your outdoor unit is a part called the contactor relay, which helps control the flow of electricity to the compressor and fan. If it gets stuck in the “on” position, the AC will continue running even when it shouldn’t. This is an electrical issue and usually requires a professional HVAC technician to diagnose and fix. Dirty Coils or Air Filters Dirty evaporator or condenser coils, as well as clogged air filters, can restrict airflow. This forces your system to run longer to reach the set temperature—or, in some cases, never reach it at all. Check your filters and coils:

During hot summer days, an air conditioner is a big blessing. But what happens when it suddenly stops cooling? I know it’s frustrating. If you are facing the same situation and wondering, why is my air conditioner not blowing cold air? Then you are not alone. It is estimated that 20% of Americans face the same issue during the summer. In this post, we will explore the most common reasons why your AC is not blowing cold air, along with easy solutions. Why it happens? Common reasons and solution There may be several reasons why your AC is not cooling. Some are given below Dirty air filter The simplest reason why your ac is not blowing cold air is a dirty air filter. Filters prevent the entry of dust, pollen, pet hair and other trash into your system. These particles build up over time and block up easy movement of air, decreasing the cooling effect. Switch off your air conditioner, remove the filter, and wash it with mild soap and water. Please leave it dry thoroughly and then place it in its place. In the case of a disposable filter, replace it with a new one. To maintain efficient airflow and cooling clean the filter after every 2 months.  Low refrigerant The most common cause of your ac working but not cooling is a low refrigerant level. For example, chemical substances such as R-410A or older R-22 run in coils as refrigerants and absorb the heat of your room to produce a cooling effect. When the coils become corroded or old, the levels of refrigerant decrease due to leakage. These low levels prevent your ac from blowing cold air. First, fix the leak and then refill the refrigerant to ensure proper cooling. Malfunctioning thermostat There are cases where your thermostat is the problem behind your air conditioner not blowing cold air but running. A thermostat is a device that controls the temperature of your ac by sensing the outside temperature. When its sensors become dirty or damaged, the system fails to accurately sense the room temperature, and thus, the AC is unable to cool when required. Sometimes, a poorly placed thermostat, especially near ovens or windows, may provide wrong readings. Expired batteries can also cause a malfunctioning thermostat. To fix it, replace the batteries, clear the area around the sensors, and place the thermostat in a cool, shady location. Clogged registers Registers are the vent covers that transfer cool air from the air conditioner to your room. Sometimes, these vents get blocked due to dust, furniture, curtains, or a rug, which limits cool air circulation in the room. The most effective way to resolve this issue is to inspect all the vents, clear out any obstructions, and clean the covers using either a vacuum or a damp cloth at regular intervals to improve air circulation. Issues with the outdoor unit Your outdoor ac unit consists of two key components: the compressor and the condenser. When one of them is not functioning properly, it may be the reason behind your aircon cooling problem. The compressor pumps refrigerant and recirculates it. When it is broken or overheated, the cooling process stops. The condenser helps remove the heat from the refrigerator. When the coils are clogged, or there is no condenser fan, the heat will not dissipate, and your house will not cool down. Regular maintenance and proper ventilation will prevent issues with the outside units and ensure your AC cools properly. Power issues When your ac is not blowing cold air, it may be due to power issues. The compressor or fans may not work due to tripping breaks, blown fuses, dead batteries of thermostats, or wiring problems. The first thing you should do is ensure your power supply is working properly. If the issue cannot be easily resolved, consider calling a professional. When to call a professional Contact a professional if your ac is not getting cold even after simple troubleshooting. Home repairs may increase the issue, especially in cases of leaking refrigerant, electrical problems, loud noises, frozen coils, and a faulty compressor. Conclusion When your air conditioner is not blowing cold air but still running, it may be due to a reason such as a dirty filter, clogged registers, low refrigerant, or sometimes electrical issues. However, such a problem could be resolved by some maintenance. When DIY fails, call the experts AC repair in Murrieta and Temecula and make your system and yourself comfortable again. FAQs Why does my ac take a long time to get cold? It may be because of dirty filters, low refrigerant and under sized ac. When to replace AC unit? After 10-15 years of working when it is frequently having cooling problems. How would I know if my refrigerant has a leak? Especially when you notice warm air from vents, hissing sounds and long cooling time may be the reason for the leak. What to do when my ac is running but not cooling the room? Simple troubleshooting such as cleaning filters, inspecting thermostats and outdoor units. If the problem is still present then call a professional. Is it safe to clean outdoor units myself?  Yes, you can clean it with a cloth or even with hose from outside. But you will need an expert while cleaning inside the outdoor unit.

Air conditioners are vital for maintaining comfort during hot weather but when they start leaking from air conditioner, it can be both frustrating and alarming. Water leakage in your AC is not just an inconvenience it can also lead to potential damage to your home. Understanding why there is water in air conditioner and how to fix it is crucial to avoid further complications. In this article, we will explore the question why is my air conditioner leaking water the potential risks associated with the issue, and step by step solutions to address the problem. Understanding the AC Water Leakage Problem Water in air conditioner is a normal part of the cooling process, as the unit removes moisture from the air. However, when you notice air conditioner dripping water inside or around the unit, it could signal a problem that requires attention. Leaking from air conditioner can be caused by various issues, and understanding the root cause can help you address it before it leads to further damage. In this article, we will examine the common causes of aircon water leaking and offer actionable solutions to fix the issue. Common Causes of Air Conditioner Water Leakage Several factors can contribute to leaking from air conditioner, and identifying the problem is the first step to solving it. Below are the most common reasons behind water in air conditioner and air conditioner dripping water. Clogged Condensate Drain Line One of the primary reasons for aircon water leaking is a clogged condensate drain line. As your air conditioner cools the air, it condenses moisture, which should naturally drain away through the condensate line. If this line becomes clogged with debris, algae, or mold, the water will back up and start leaking from air conditioner. Dirty Air Filters When the air filters in your AC unit become dirty, they restrict the airflow, causing the evaporator coils to freeze. Once the ice thaws, there’s more water in air conditioner than usual, and the system can’t drain it efficiently. This often leads to air conditioner dripping water inside the unit. Low Refrigerant Levels Low refrigerant levels are another cause of aircon water leaking. If the refrigerant is low, the coils can freeze up. As they thaw, excess water accumulates and can lead to water leakage from the AC. This is a more serious problem, as low refrigerant levels also affect the cooling efficiency of your unit. Faulty Pump or Overflow Tray A malfunctioning pump or overflow tray can cause water in air conditioner to overflow or leak. These components are designed to collect and redirect the water away from the unit. If either part is damaged or misaligned, water may spill out, resulting in air conditioner dripping water where it shouldn’t. Installation Issues Improper installation of your air conditioner can lead to leaking from air conditioner as well. If the unit is not level, it may prevent proper drainage of the condensed water. Additionally, incorrect installation can result in water pooling inside the unit, leading to leaks and possible damage. How to Troubleshoot and Fix the Problem Once you have identified the potential cause of air conditioner dripping water, here are some steps you can take to resolve the issue. Inspecting and Cleaning the Drain Line A clogged drain line is one of the most common causes of leaking from air conditioner. To fix this, inspect the line for blockages. You can clean the line using a wet/dry vacuum or by flushing it with a mixture of water and bleach to clear out mold and debris. Replacing or Cleaning the Air Filters If your filters are clogged, they could be the reason for excess water in air conditioner. Replace or clean your air filters regularly to ensure smooth airflow. Dirty filters should be replaced every 1–3 months, depending on usage. Checking Refrigerant Levels If you suspect low refrigerant is causing aircon water leaking, it’s important to have a professional check and refill the refrigerant. Low refrigerant not only leads to water leakage but also reduces the cooling efficiency of your AC unit. Inspecting the Pump and Overflow Tray Inspect the pump and overflow tray for any damage or misalignment. If the pump is broken, it will need to be replaced. Misaligned trays should be adjusted to allow proper water drainage. Preventive Measures to Avoid Future Leaks To avoid future issues with air conditioner dripping water follow these preventive steps: Regular maintenance: Have a professional service your AC unit at least once a year to clean components and check for potential problems. Change air filters regularly: Ensure your air filters are cleaned or replaced every 1–3 months. Check the drain line: Periodically inspect and clean the condensate drain line to prevent clogs. When to Call a Professional Technician While minor issues like clogged drain lines and dirty filters can often be fixed by the homeowner, other problems may require professional help. If you’re unsure about the cause of the leaking from air conditioner or if you’ve tried troubleshooting without success, it’s best to call a professional. A technician can handle more complex problems such as low refrigerant levels, compressor issues, or electrical malfunctions. Conclusion Experiencing leaking from air conditioner or air conditioner dripping water is frustrating, but by understanding the causes and taking the right steps to fix it, you can keep your system running efficiently. Regular maintenance, proper cleaning, and timely repairs will help prevent water in air conditioner from becoming a recurring issue.
