Always Fiddling With the Thermostat? Something May Be Wrong


Although there are many high-end thermostats available on the market today, including energy-saving smart thermostats that come up with their own programming, at their core thermostats operate on a basic principle: they signal to the parts of the HVAC system when to turn on and turn off. If your thermostat and HVAC system are operating correctly, then all you need to do for comfort during a season is to find a single setting for the day when people are home and a different one for night and when people are away. For example, during cold weather, 68°F is the recommended daytime setting.

You shouldn’t need to continually adjust the thermostat throughout the day to be comfortable. If you find that you are—because the house always seems a bit too warm or a bit too cold—it’s a reason to be concerned about the HVAC system. The thermostat may be malfunctioning, or the heater could be. Either way, we recommend you call us for heater repair Sherman Oaks, CA.

What the Problem Might Be

There are many possible causes for a thermostat that can’t land at the right temperature. The first option to consider is that the thermostat is at fault. A thermostat registers the general temperature of the house with a sensor, and if the sensor reading is miscalibrated, it will be difficult to find the ideal setting. Fortunately, miscalibrations are usually easy for professionals to fix.

If the thermostat is over ten years old, this may be a sign the unit is decaying and it’s time to replace it. Any thermostat that still has a manual needle readout is too old, and this problem with temperature settings is the sign to get a new one.

Now we go deeper into the HVAC system to trouble with the heater itself. A common source of a house never getting to the right temperature is that its heater is short-cycling, i.e. it’s turning on and off too frequently. A heating system should run for at least 15 minutes each heating cycle before cycling down, and if it starts running shorter than this, the house will get caught in never getting warm enough except for some parts that get too hot. Short-cycling can be the fault of a clogged air filter, worn-down motors, or a poor installation.

Another source of the problem can be leaks in the air ducts. In this case, the thermostat and heater are working as they should, but some of the heated air is failing to get to the rooms, creating an imbalance and the heater not reaching the desired temperatures. Fixing this requires having professionals test the ducts and then seal them with special equipment; you can’t use duct tape for this job!

Don’t worry if you’re still unsure why the thermostat settings are giving you grief. It’s our job to do the detective work and get to the bottom of it. We’ll diagnose the problem and see that your HVAC system is restored, along with your comfort.
