Signs Of Thermostat Problems At Home

Here are a few of the signs that suggest you have a faulty thermostat problem at home:

Problem 1: Thermostat Doesn’t Reach The Set Temperature

The thermostat allows you to control your HVAC system. You can set the temperature you want, and the unit will follow what you input in the thermostat. However, if the room feels the same even after a few minutes have passed, you could have a thermostat problem. Check whether the thermostat is near any heat source, like a heat grate or a window. As your thermostat is exposed to heat, it will sense the wrong indoor temperature. It will think that the indoor environment is already hot, forcing the furnace to shut down before the set temperature is reached. Keep the thermostat away from heat sources. Use curtains to block the sunlight from windows as well.

Problem 2: Old Thermostat

Old thermostats are more likely to experience more problems. Thermostats are made to last for a long time, but their effectiveness significantly reduces at some point. They are harder to use, and you will have a lot of connectivity issues. It might also be harder to clean, and the sensitivity might also drop. Consider replacing your old thermostat with a modern one that can improve your convenience and efficiency.

Problem 3: Thermostat Is Dirty

A thermostat should be able to read the indoor temperature correctly. If it cannot do its job properly, it might be because your thermostat is dirty. Dust buildup inside the thermostat can cause errors, so it needs to be fixed right away. Open the case carefully and use a soft brush to remove dust and dirt.

Problem 4: Thermostat Miscalibration

Thermostats are equipped with internal sensors that were calibrated so that they can work properly. As time passes, your thermostat’s efficiency is reduced, and miscalibration occurs. You’ll end up experiencing uneven heating inside your home. Your thermostat might also give the system incorrect commands, like the fan will switch off prematurely. This problem can cause worn-out components, high utility bills, discomfort, and shortened lifespan.

Problem 5: Thermostat Display Doesn’t Work

The thermostat has a small display screen that lets you know the HVAC system’s current state, like the operating mode and the current temperature. Some thermostats have a touchscreen display, so you can use it to change the settings directly. Having a faulty display means that you cannot check the current temperature and change the settings.

The system might have been turned off, so try switching it back on. If that doesn’t work, it could be that your thermostat needs new batteries. Check if there are any loose wires and incorrect connections as well.


Advantages Of A Thermostat Replacement

Replacing your malfunctioning thermostat comes with many benefits. Here are some of them:

1. Save Money On Your Heating & Cooling Costs

HVAC units consume a lot of energy. Therefore, many homeowners are always on the lookout for ways to reduce their HVAC utility bills. One of the most effective ways to do this is to replace your old thermostat with a programmable one. This way, you can adjust the settings to fit your schedule and needs. For instance, the system can lay low during office hours and come back to life when you are about to arrive home. Modern thermostats also have energy tracking features that lets you know the amount of energy you are consuming and how much your energy costs are.

2. Auto Temperature Adjustments

A programmable thermostat allows you to input the settings you want for the day in one go, and it will do so on its own automatically. This way, you don’t have to keep going to your thermostat just to change the settings. You don’t have to worry and go about your daily activities, while your thermostat will direct your system to do what is needed automatically.

3. HVAC System Optimization

You do not need to replace your whole system to get the improvement you need with your HVAC operation. You can make small but significant changes, and your thermostat is always a good place to start. This will allow you to gain the reliability, convenience, and efficiency you need without breaking the bank.

Keep in mind that although a modern thermostat will help increase your home’s comfort and efficiency, it is still essential to replace your outdated HVAC unit with a new one. A modern thermostat will work best with a new HVAC system so that you get the highest level of efficiency and comfort possible.

4. Remote HVAC System Control

Some programmable thermostats are equipped with connectivity options that make them more convenient to use. For instance, some can be connected to your Wi-Fi so you can control your system via your smartphones even if you are not at home.



Thermostat issues can typically be fixed with easy solutions, like cleaning, changing its location, and replacing old batteries with fresh ones. However, sometimes you need to replace it with a new thermostat to increase the reliability and efficiency and get features like auto-adjustment and wireless connectivity.
