How To Troubleshoot Your Air Conditioner Thermostat?

The thermostat is a primary component of your air conditioner. And if something went wrong or if it’s not installed properly, then chances are this device would not function the way it’s intended to be.

However, not all thermostat issues require the help of a technician for there are some troubleshooting steps that you can do on your own before calling an HVAC expert. So read more as we are going to share some DIY information on how to troubleshoot your air conditioner thermostat in today’s guide.


Things That You Need To Check When Performing A Thermostat Troubleshooting Process

Before considering the services of a professional, you need to check on these things first:

Is The Device Receiving Power?

If the air conditioner thermostat is always shutting down or the backlight keeps turning off, the first thing you need to do is to check if the device is receiving enough power. Thermostats are powered by batteries and your AC itself. So you need to ensure that there is enough power coming from these sources.

Likewise, you also need to check if the circuit breaker has tripped, which also causes the device and the whole air conditioning unit to lose power. We also recommend that you change the batteries and replace them with a fresh set.

Is The Thermostat Situated Near Sources Of Warm And Cold Air?thermostat installation

If the device is installed in very cold or warm areas, then it won’t be able to make an accurate reading of the temperature in your home. And as a result, it won’t be able to activate when cooled air is needed inside the house. So make it a point that the thermostat is installed in areas away from windows, vents, direct sunlight, and any other factors that might influence the temperature around the house.

Is The Device Properly Mounted On The Wall?

Proper installation is also necessary for the device to function well. If not, then it will only give you faulty readings which can then result in waste of energy (as reflected in your monthly electric bill).

So try to use a bubble level and check if the thermostat is properly mounted on the wall. Also, make sure that it is installed at least 5 feet from the floor to ensure accurate readings at all times.

Is The Thermostat Dirty?

And one last thing that you need to check is if the AC is dirty because any dirt buildup in your cooling system can also cause the air conditioner thermostat to malfunction. So clean up your AC unit by opening the cover and remove any dirt that you can find.

The 5 Features Of Environment-Friendly HVAC Units


In recent years, technology has made it possible to develop products and process that are not harmful to the environment. And with this in mind, the AC industry is no exception to these innovations as eco-friendly air conditioners are becoming widespread in use and manufacturers are phasing out the use of ozone-depleting refrigerants to give way for “clean and green” alternatives without compromising convenience.

Read more as we are going to tackle the 5 features of environment-friendly HVAC units in today’s entry.

Size Does Matter

This may come as no surprise but the size of the AC unit does play a role in its eco-friendliness. And the reason for this is that experts have found out that some people just install HVAC units without really considering the size of their homes.

Now if a wrong size of AC is installed, it will consume more energy to cool down the house, which will then produce more carbon emissions into the air (since most ACs are run by fossil fuels such as coal) and harming the environment in the process.

Good thing manufacturers have found a way to maintain this balance by producing AC systems in different sizes to suit the needs of every home or establishment.

Customized Matched Systems

In order to achieve optimal energy efficiency, some environment-friendly HVAC units make use of different energy sources for heating and cooling.

In other words, AC companies have developed modern ways to customize each part of the AC system from the indoor coils to the thermostat to meet the individual heating & cooling needs of every household.

2-Stage Compressors

Nowadays, air conditioners have 2-stage compressors to automatically compress more during hot days and less during cooler days to save more on energy.

Geothermal Heat Pumps

This innovation makes use of the earth as a natural heat-sink so the AC can capitalize on the flow of warm air for a certain area and convert it into cooled air. This feature has made eco-friendly ACs up to 40% more energy efficient compared to its predecessor units.

Smart (Programmable) Thermostats

Lastly, the introduction of home automation has also made it possible for environment-friendly HVAC units to use smart thermostats to automatically set the unit remotely so the entire house will be already cooled by the time you go home.

This simple advancement is by far the most effective feature since it prevents the appliance from exerting too much effort in producing cooled air as the device can automatically turn off the AC when the room has reached the appropriate temperature.
