04 Jun Why Your AC Won’t Turn On In Extreme Heat: Troubleshooting Tips
Summer temperatures in Folsom can soar, and few things are more frustrating than trying to turn on your AC only to realize it isn’t working. When the heat outside feels unbearable and the inside of your home won’t cool down, it creates an uncomfortable and even unsafe living environment. That’s when most homeowners look for quick answers to get their system running again.
If your AC won’t turn on during extreme heat, there can be several different causes. Some require simple checks, while others point to deeper issues that will need help from our technicians. Before scheduling AC repair in Folsom, try going through a few common problems that could be interrupting your unit’s performance.
Initial Checks to Perform When Your AC Doesn’t Turn On
It helps to start with the basics before assuming the worst. Some issues can be resolved by checking the settings, power supply, or filters. These are easy things to inspect without tools or training.
1. Thermostat Settings
If your thermostat isn’t set correctly, your AC might not kick on even if the room feels warm. Make sure the setting is switched to cool and that the temperature is set lower than the current room temperature. Dead or weak batteries in a thermostat can also cause it to stop communicating with your AC system, so it may be a good idea to replace them.
2. Check the Power Supply
It’s easy to overlook a tripped breaker or an unplugged connection. Go to the electrical panel and see if the breaker for your AC unit has flipped. If so, switch it back on. Be cautious. If it trips again right away, there could be a bigger electrical issue, and you should stop and wait for our technicians to check it out.
3. Inspect Air Filters
Clogged air filters can cause the entire system to stop working. If air can’t flow through freely, it puts stress on your system, and some high-efficiency units will even shut down to protect themselves. Find your indoor air return and check the filter. If it looks dark and clogged with dust, replacing it may restore airflow. As a rule of thumb, most filters need to be changed every one to three months depending on usage and indoor conditions.
Catching these small hiccups early could save you the trouble of a full breakdown. But if the problems continue, it’s likely time to look deeper into mechanical issues that happen when temperatures rise.
Common Causes Of AC Failure In Extreme Heat
When it’s especially hot outside, your AC works harder than usual to maintain a comfortable temperature inside. That extra stress can aggravate existing problems or cause new ones. Here are a few common failures that can happen during peak summer heat:
– Overheating Components
AC units are built to run frequently, but continuous use during a heatwave can push motors and compressors to the limit. When they overheat, safety switches may shut the unit down to prevent major damage. This might happen more frequently if your system hasn’t been serviced in a while.
– Refrigerant Issues
Low refrigerant levels or leaks keep your AC from cooling properly. Over time, leaks can happen in the coils or connections. If your AC seems to be running but the air coming out isn’t cool, this could be the reason. Refrigerant problems are not something you can fix without training and proper tools. Our technicians can safely check for leaks and recharge the system if needed.
– Frozen Evaporator Coils
This one might sound strange given the heat, but frozen coils are common if airflow is restricted or refrigerant is low. When coils freeze, your AC can’t pull heat out of your home. Signs include frost on the unit, weak airflow, or loud hissing sounds. Once the coils freeze, the entire cooling cycle is interrupted.
Extreme heat puts every part of your AC system under pressure. If regular checks don’t fix the problem, the next step is to review troubleshooting techniques that get things moving again without risking costly damage.
Troubleshooting Tips to Get Your AC Running Again
Once you’ve ruled out the basics and identified what might be wrong, the next step is to attempt safe, simple solutions that may help restore cooling to your home. These steps may offer a quick recovery but are not long-term fixes. If your AC still doesn’t respond, avoid forcing it to run and contact our professionals for AC repair in Folsom.
Here are some quick tips to try:
– Reset the System
Your unit may simply need a reset. Turn the thermostat off, wait a few minutes, and restart it. At the same time, shut off the system at its main switch or breaker, then power it back on. Some newer models have a reset button near the compressor. This could clear minor electronic glitches and bring the unit back to life.
– Open Blocked Vents and Registers
Furniture, rugs, or curtains may block vents and restrict airflow. Walk through every room and double-check that all vents and returns are open and unobstructed. Clear paths around these points allow air to circulate properly throughout the system.
– Clean Around the Outdoor Unit
If your outdoor condenser is surrounded by tall weeds, trash, or dirt buildup, it may not be able to release heat correctly. Gently clear away any obstructions or debris within two feet of the unit. Be careful not to damage the fins or components. Just use your hands or a leaf blower if it’s safe to do so.
– Watch for Warning Signs After Restart
After these resets or cleanups, if your system starts up but shuts down again quickly, blows warm air, or starts making noises, stop using it. That’s a sign that something more serious is going on. Running the AC in this condition could cause more damage and lead to more expensive repairs.
One homeowner in Folsom mentioned their AC stopped working after a week of steady 100-degree weather. After checking the thermostat and flipping the breaker, they noticed the outdoor unit was completely covered in leaves. Once cleared, the unit kicked back on. While not always this simple, sometimes a hands-on inspection can lead to a quick result if you know what to look for.
If these basic troubleshooting steps don’t get your AC operating again, it’s time to move forward with professional help. Heat-related AC breakdowns are common in Folsom during this time of year, and catching the issue early can make a big difference.
