When your air conditioner suddenly stops cooling your Herriman home in the middle of summer, one common culprit is the thermostat. This small device plays a big role in keeping indoor temperatures steady and comfortable. If it stops working the way it should, your whole system might shut down or operate at the wrong times, leaving your home hotter than it should be.
It is not always easy to know if the thermostat is causing the issue, but certain signs can give it away. Maybe the display goes blank, settings keep resetting, or your AC does not respond when it should kick on. These kinds of problems leave many homeowners unsure about what has gone wrong or what steps to take next. Understanding how thermostat issues affect your AC system is the first step in fixing the problem and getting your comfort back on track.
Common AC Thermostat Problems
Thermostat problems can come in several forms, and it helps to recognize the symptoms early. Some issues might seem small at first but can cause system failures or energy waste over time. Here are a few problems that often come up in homes across Herriman during the summer months:
1. Thermostat Doesn’t Turn On
If the display is dark and does not light up even after pressing buttons, the thermostat may have no power. This could be from dead batteries or an internal wiring issue.
2. Inaccurate Temperature Readings
Sometimes the thermostat reads a room as being cooler or warmer than it actually is. This leads to the AC either not turning on soon enough or shutting off too early, which causes discomfort. Heat from nearby appliances, windows, or poor placement on the wall can also play a role.
3. Not Communicating With the AC Unit
You may hear the click from the thermostat, but the AC stays off. If the thermostat cannot send a signal to the system, it might have a wiring issue or internal error that needs checking.
4. Frozen or Unresponsive Controls
When buttons stop working or touchscreens lag, it could be a software glitch or circuit problem. Without control of the settings, you cannot adjust the temperature or fan schedule as needed.
Problems like these do not just affect comfort. They can also wear down your AC system if it is cycling on and off too frequently or running longer than needed. Over time, this can shorten the system’s lifespan and increase repair costs.
DIY Thermostat Checks To Try First
Before calling for help, there are a few things you can check at home. These steps are safe for homeowners and can sometimes get things working again without deeper inspection. Walk through each one slowly, and always handle the thermostat gently.
– Replace the Batteries
If your thermostat runs on batteries, try switching them out. Weak batteries can shut down the screen or mess with connections.
– Check Basic Settings
Go through your preset schedules and preferred temperatures. Sometimes settings can be accidentally changed, especially if guests or kids have access to the controls.
– Look at Placement and Obstruction
Your thermostat should be placed away from direct sunlight, vents, and heat-generating appliances. If something nearby is affecting it, the readings may be off.
– Inspect the Wiring
Remove the cover carefully and look at the wires inside. If any are loose or hanging, that could be the cause. Do not try to fix or move wires on your own. This is where you stop and call our technicians.
– Reset the Thermostat
Some models have a reset feature that puts the thermostat back to factory defaults. This can remove glitches caused by errors in storing data or updates.
While a few of these checks might bring the system back to normal, a persistent issue means it is time to stop guessing. Thermostat problems can shift quickly from small annoyances to bigger system-wide damage, so it is important not to delay if the steps above do not make a difference.
When to Bring in Professional Help
If none of the basic troubleshooting steps work, it is likely time to stop investigating on your own. A thermostat that keeps causing issues could be a sign of something deeper, like failing internal components or an electrical problem within the AC system. In some cases, the thermostat may not even be compatible with your setup, especially if you have recently upgraded part of your system. That mismatch can cause missing signals, fan delays, or complete system shut-offs.
You should also pay attention to signs of wiring problems. If the thermostat display turns on and off randomly, or if the system makes clicking noises without turning on, there could be a short or loose connection. Issues like these should never be ignored or patched with temporary fixes, as they can pose safety risks over time. Electrical components inside an AC system are complex, and getting to the bottom of an issue often requires specialized tools and knowledge.
When reinstalling or replacing the thermostat becomes the likely solution, our professionals can check compatibility, wiring, and system programming. This avoids guesswork and helps prevent future issues from popping up due to incorrect settings or installation mistakes. Accurate diagnostics ensure the root of the problem is found the first time, saving you from repeated breakdowns and extra service calls later.
Preventive Maintenance Tips for Ongoing Comfort
Avoiding future thermostat problems starts with a good maintenance routine. While it may not be the first thing homeowners think about when it comes to AC care, keeping the thermostat in top shape is just as important as cleaning vents or replacing filters. Preventive action now can save you from sudden breakdowns during Herriman’s peak summer heat.
Here are a few simple ways to keep your thermostat running efficiently:
– Schedule periodic checks to confirm it is responding quickly and correctly to adjustments
– Keep the area around the thermostat clear of lamps, electronics, and direct sunlight
– Dust the unit gently to avoid buildup inside button triggers or sensor areas
– Upgrade to a programmable or smart thermostat if you are still using a manual one
– Include thermostat inspections as part of annual AC service visits
Smart thermostats can be a helpful long-term investment. They allow more precise control of your cooling settings, cut back on unnecessary runtimes, and learn your usage patterns. Many options even let you check performance remotely, giving you alerts when the AC is not operating as usual. This extra layer of monitoring helps you stay ahead of small problems.
Regular AC service also ensures that all parts of your system, including the thermostat, are working well together. Issues often show up in patterns, with thermostat problems sometimes signaling larger concerns in the system. Maintenance appointments help catch small things before they turn into major inconveniences.

Staying ahead of these issues by knowing when to troubleshoot and when to call in help can keep your home comfortable all summer long. Reliable cooling does not happen by chance.
