In Sherman Oaks, keeping cool through the warmest months means having an air conditioning system that runs when you need it most. When your AC suddenly won’t power on, it can create stress, especially if temperatures are climbing. You expect comfort at home, and being without a working unit can interrupt your day fast. Whether you’re getting ready for work or trying to settle the family in for the night, that moment of silence from your AC can throw everything off.
There are several reasons your air conditioner might not be turning on. Some issues might be simple to identify, while others point to more serious electrical or mechanical faults. It’s important to troubleshoot quickly and safely so you can figure out the cause and get things running again. Waiting too long or guessing at the problem can lead to bigger repairs later. If you’re in Sherman Oaks and need help, knowing the common steps to check can go a long way in deciding what to do next.
Check The Thermostat Settings
Start with the most basic part of your system: the thermostat. It sounds obvious, but often the fix is just a small correction in the settings. Before looking into more technical causes, look here first.
Make sure to do the following:
– Confirm the thermostat is switched to “Cool”
– Set the temperature at least a few degrees below the current room temperature
– Look for low or dead batteries if your thermostat runs on battery power
– Check if the display is working properly or if it’s gone blank
Wall-mounted thermostats, especially older models, can sometimes suffer from loose wiring or poor battery connection. If the screen is blank, pop off the cover and check the battery compartment. If the batteries look fine but there’s still no display, it may be a sign of a wiring or internal issue.
Smart thermostats, while more advanced, can also freeze up or lose their Wi-Fi connection, which may prevent the system from receiving your commands. A quick reset through the thermostat’s settings usually restores its functions.
People often call for AC repair after adjusting the thermostat wrong without realizing it. Taking two minutes to double-check each setting here can help spot problems early.
Inspect The Power Supply
Once you’ve confirmed that the thermostat settings are correct, check whether the unit is getting power. Air conditioners need a consistent electrical supply, and small disruptions can stop everything from working.
Follow these steps to inspect the power:
- Head to your main electrical panel and check for tripped breakers. Look for any breaker labeled “AC” or “HVAC” that may be in the middle position.
- If you find a tripped breaker, fully switch it to the OFF position before turning it back ON.
- Locate the external disconnect switch near your outdoor AC unit. Make sure it is in the ON or UP position.
- Inspect the fuse box or service switch for your AC system, if you have one nearby. Sometimes these fuses blow without warning and cut power to the unit.
AC units may shut off automatically due to power surges, fluctuations, or overheating. If power goes out even briefly during hot weather, some systems won’t start again until they’re manually reset.
While it might seem small, checking your power supply can rule out larger concerns. These resets can be quick fixes, but if the breaker keeps tripping or the power doesn’t stay stable, a technician should take a closer look to avoid damage to the wiring or compressor.
Look For Obvious Issues
After checking the thermostat and power supply, a visual inspection of the AC unit itself can often point out what’s wrong. A quick look outside and around the main system can help you catch problems before they get worse. In many cases, something small and visible might be blocking or disrupting operation.
Start by walking around the outdoor unit. Look for disconnected wires, burnt marks, or dents that could suggest the unit was hit or tampered with. Check if the cover panel is closed and secure. In some units, a loose panel will trip a safety switch that prevents it from turning on.
Inspect the space around the unit for physical blockages such as:
– Overgrown shrubs or tree branches pressed up against the unit
– Furniture, storage boxes, or garden tools placed too close
– Trash or leaves that might have gathered around the vents
Even in Southern California, outdoor debris like dusty buildup or dried leaves can clog vents or get sucked in by the fan. An obstructed fan can cause the system to overheat or trip a safety sensor. Clear the area around the AC and gently clean off any loose dirt from the housing.
It’s also a good idea to glance at exposed cables. If you see cracked insulation, frayed ends, or unusual bends, don’t touch them. That could indicate damaged wiring, which poses a risk and needs to be examined by a technician.
Small checks like these won’t fix deep internal issues, but they can help you eliminate external factors. When the problem isn’t immediately obvious, it’s usually time to bring in help.
Call A Professional If Troubleshooting Fails
If the steps above don’t resolve the issue, the problem may be more technical than what can be seen from the outside. Internal system errors, failed capacitors, broken motors, or faulty sensors can prevent an AC unit from powering on. These components require special tools and the training to inspect and repair them safely.
Our professionals begin by running diagnostic tests on your system. This includes voltage checks, capacitor testing, and system communication scans. Since every home layout and unit installation is different, our technicians approach each case with a fresh look instead of applying a general fix.
Trying to handle electrical components without proper certification is dangerous and can void warranties. That’s why contacting our team makes more sense once it’s gone past the basic checks.
Repairing the AC correctly the first time helps avoid future breakdowns and usually costs less than repeated trial-and-error fixes. Getting professional support early also gives you answers faster, so you don’t have to sit around waiting in Sherman Oaks heat.
Prevent Breakdowns With Regular Maintenance
Staying on top of maintenance can lower the chances of your AC suddenly quitting in the middle of summer. Consistent upkeep lets you catch small wear-and-tear signs before they grow into bigger repair needs. Many of the problems that lead people to call for AC repair in Sherman Oaks begin with neglected maintenance.
Here are a few ways homeowners can support their systems between appointments:
– Replace air filters every 1 to 2 months during active seasons
– Keep vents and intake grilles clean and unblocked
– Schedule annual inspections before summer hits
– Keep the surrounding area around the outdoor unit clear of clutter and vegetation
– Listen for unusual noises during regular use and report them early
When our technicians handle maintenance, they often spot hidden problems like refrigerant leaks, slightly burnt wiring, or pressure imbalances. Finding those early means your AC can be fixed during a scheduled visit rather than an emergency call on a hot day.
Regular service also helps the system run more efficiently, which can make it easier to handle higher temperatures without overworking the equipment. Simple habits plus seasonal check-ups keep everything functioning how it should.
