• SETTING THERMOSTAT’S TEMPERATURE:

The first thing you need to do is set your thermostat’s temperature. The operating mode should be “Cool”, and the fan should be in “Auto” mode. Along with this, set your thermostat to the lowest possible temperature and then leave the unit for some time. Now check whether it is cooling or not.

• CONFIGURING OTHER SETTINGS:

It is essential to put the correct time on your thermostat. Along with this, check other settings as well. In case of wrong settings, the cool on indicator might start blinking.

BATTERY REPLACEMENT:

If you own a battery-operated thermostat, then make sure to check the working of its batteries. Worn-out batteries might cause this issue, so make sure to replace the batteries once they stop working.

• FAULTY WIRING CHECKUP:

The wiring in your thermostat might be faulty. The presence of such wiring will cause this issue.

• CHECKING THE COOLING UNIT:

You should also check the cooling unit. Make sure that it is receiving enough power. You can also restart your device to resolve this issue.

• CHECKING THE MAINTENANCE:

Your AC filters come with a life duration. If these filters have completed their time, they will stop the AC unit from working. At this point, you have to make sure that the AC filters are cleaned and still have some time to be working.

• RESETTING THERMOSTAT:

If nothing works out for you, then it is time that you reset the thermostat. Resetting would help you to solve other problems as well.

AC NOT BLOWING COLD AIR – TROUBLESHOOTING METHODS

If you are experiencing that the AC unit is not blowing cold air, then there could be two possibilities. The number 1 possibility is that no air is coming from the vents at all. While the second possibility is that warm air is coming from the vents.

If you are experiencing the former case, try the following fixes.

• Make sure that there is sufficient power being provided to your thermostat
• Cross-check the settings of your thermostat
• Replace the AC or Air filters if they require a replacement

If you are experiencing the latter case, you could try the following fixes.

• Keep the outside unit of your system clean
• The fan should be set to “Auto” mode

WHY SHOULD I SET MY THERMOSTAT TO “AUTO” MODE?

You will generally come across two options; auto or on. If you set your thermostat to “ON” mode, it will move the cool air around the house accordingly. Along with this, the fan will continue to work even when the AC has been turned OFF.

On the other hand, if you talk about “Auto” mode, then it is an energy-efficient option to consider. The fan will only work in auto mode when the heating or cooling unit is ON. Another advantage of setting your fan to AUTO mode is that the fan will take all the moisture from the coils and drain it outside.

However, this is not possible if the fan is continuously running. In this case, the moisture will stay inside and will bring further inconveniences for you. If this happens, the moisture and warm air will be blown back into the house.

HEAT OR COOL, WHAT TO CHOOSE FOR MY THERMOSTAT?

Choosing between heat and cool mode depends. If your house is sweltering, then set the thermostat to cool mode. But if your home is chilly, change the mode to hot. Also, if you want the air to circulate throughout the house, set the fan mode to “AUTO”.

TURNING YOUR THERMOSTAT ON COOL MODE:

By now, you must know about your thermostat’s cool mode. Briefly speaking, the cool mode brings the AC into working, and you start experiencing a relaxed atmosphere. You can also pick the maximum temperature while in this mode.

You can also perform a dehumidifying process by using the cool mode. It is up to you to use a cool mode or any other mode according to your preference.

IDEAL COOLING TEMPERATURE OF YOUR AC:

If you want to have complete comfort and save your dollars, then choose an ideal cooling temperature for your AC. Luckily, we have already figured the temperature out, i.e. 78 Fahrenheit.

This is just a guess. You can find the perfect temperature for yourself as well. However, if you want to save on your cooling costs, you can adjust the temperature at night when most people are asleep.

TEMPERATURE ADJUSTMENT:

If you want to warm up your house, you only need to raise the temperature. Similarly, reduce the temperature if you’re going to cool it up.

But if you want the air to circulate in your house, you must set the fan to “ON” mode and don’t need to adjust the temperature.

INDOOR AND OUTDOOR TEMPERATURE DIFFERENCE:

The air conditioners are designed in such a way that they cool down your house 20 degrees lower than the outdoor temperature. If the outdoor temperature is 90 F, then the inside temperature of your home would be 70 F.

BLINKING FURNACE LIGHT:

• RED LIGHT:

If your furnace blinks red light, it could mean many things; for example, there is an issue with the pressure switch, the inducer has become faulty, or an ignition failure.

• GREEN LIGHT:

The blinking green light on your furnace could mean one of two things;

1. The furnace provides heat
2. The furnace is ON, but there is no heat

THERMOSTAT BLINKING HEAT ON – WHY?

CAN I USE AC AND FAN TOGETHER?

It is a common misbelief that whenever you use AC, you cannot use a fan with it. Using both these things in combination is a good option. However, if you don’t use this combination, it is also okay, but if you use it, you will feel much more comfortable than usual.
