Troubleshooting tips and steps to take when your air conditioner is blowing warm air.
AC Not Cooling? There’s nothing worse than coming home on a hot day only to realize your AC is not cooling properly. If your AC is not cooling your home, it can be incredibly frustrating, especially during a heatwave. Whether it’s a minor issue or a more complex problem, there are steps you can take to troubleshoot and potentially resolve the issue when your AC is not cooling becomes evident before calling in a professional. In this blog post, we’ll cover some common reasons why your AC is not cooling and what you can do to address the AC not cooling situation and get it back up and running.
1. Check the Thermostat Settings
Sometimes the issue is as simple as an incorrect thermostat setting. Before diving into more complicated troubleshooting, double-check your thermostat. Ensure it’s set to the cooling mode (usually marked as “Cool”) and that the temperature is set lower than the current room temperature. If your thermostat is programmable, make sure it hasn’t been accidentally adjusted to an energy-saving mode or a higher temperature.
If the settings appear correct, try adjusting the temperature slightly and see if the system kicks on. If this doesn’t resolve the issue, there may be a deeper problem at play.
2. Replace or Clean the Air Filters
One of the most common reasons for an AC not cooling properly is a clogged or dirty air filter. Over time, air filters accumulate dust, dirt, and other debris that can restrict airflow. This not only reduces the efficiency of your system but can also cause it to freeze up, preventing cool air from circulating properly.
To solve this problem, replace the air filter with a new one or clean the reusable filter. Be sure to use the correct size and type of filter for your system, and make filter replacement a regular part of your home maintenance routine.
3. Inspect the Vents and Airflow
Another possible reason for your AC not cooling could be blocked or closed vents. Make sure all supply and return vents are open and unblocked by furniture, curtains, or other obstructions. Blocked airflow can severely limit the efficiency of your system and prevent it from cooling your home properly.
If your vents are open and unobstructed, consider checking the ductwork for leaks or gaps. Leaky ducts can cause cool air to escape before it reaches the intended areas of your home. If you suspect a duct issue, contact a professional to inspect and seal the ducts for optimal performance.
4. Check the Outdoor Unit
Your AC system’s outdoor unit plays a key role in cooling your home. If it’s dirty or obstructed, it can affect the performance of your air conditioning system. Check the outdoor unit to ensure there’s no debris such as leaves, branches, or dirt blocking the condenser coils. These coils are responsible for releasing heat from your home, and if they’re clogged, it can prevent your AC from cooling properly.
Use a garden hose to gently clean the coils if necessary. Be sure to turn off the power to your AC unit before performing any maintenance on the outdoor unit. If the coils are heavily dirty or you’re unsure about cleaning them, it’s best to call a professional technician.
5. Check the Refrigerant Levels
If your AC is not cooling, low refrigerant levels could be the culprit. Refrigerant is the substance responsible for absorbing heat from the air inside your home and releasing it outside. If there’s a leak or the refrigerant level is low, your AC will struggle to cool the air.
Unfortunately, checking and refilling refrigerant is not a DIY task, as it requires specialized tools and knowledge. If you suspect low refrigerant levels, it’s important to contact us so we can send one of our professional technicians who can diagnose the issue, locate the leak, and recharge the refrigerant. Operating your AC with low refrigerant can cause long-term damage to the compressor, so it’s crucial to address this issue promptly.
6. Reset the Breaker or Fuse Box
Sometimes, a tripped circuit breaker or blown fuse can prevent your AC unit from running. If your AC suddenly stops cooling, go to your electrical panel and check if the breaker for the AC unit has tripped. If it has, reset the breaker and wait a few minutes to see if the AC starts cooling again.
If the breaker keeps tripping or you’re unsure which circuit controls the AC, consult a professional electrician or HVAC technician to inspect the system for electrical issues.
7. Consider Scheduling Professional AC Maintenance
If you’ve tried the above steps and your AC is still not cooling, it may be time to call in a professional. Our expert technicians can perform a thorough inspection to diagnose and fix any underlying issues that may be affecting your system’s performance. From checking refrigerant levels to inspecting the compressor, a professional can ensure your AC is working efficiently and effectively.
Regular professional maintenance is also essential to keeping your AC running smoothly year-round. Scheduling annual maintenance before the peak cooling season helps identify potential issues before they become bigger problems.
AC Is Not Cooling? Final Steps
When your AC stops cooling, it can be frustrating, but many common issues can be resolved with a little troubleshooting. Start by checking the thermostat, replacing the air filter, and ensuring proper airflow throughout your home. If you’ve checked all the basics and the problem persists, it’s time to consult a professional HVAC technician who can get your system back in shape.
