There are a number of reasons why your air conditioning also known as A/C system is not working, as it’s not cooling your home as required. We will look at a number of reasons that could be the cause:
Thermostat set to “ON” instead of “ AUTO”
This will result to your AC blowing out cool air and at other times lukewarm air. When the fan’s setting is “ON” this result to the fan running 24/7 even at times when the air is not cooled. This can be rectified by setting the thermostat to AUTO.
Dirty Air Filters
With dirty air filters the airflow to your AC is reduced, which causes the following reasons:
- The evaporator coil literally freezes; it turns into a block of ice which blocks air. This means that your home will get very little of the cooled air.
- The AC struggles to circulate enough of the cool air, which is to make your home have the desired temperatures.
To solve this problem check your filter and change it if it looks like it’s on the right.
Dirty Outside Unit.
The AC unit inside, which is the evaporator, absorbs heat that is from your air; then transfers it to the condenser in the outside unit. The condenser cannot dissipate heat, in the event that it’s either dirty or crowded with debris. Therefore, this makes you’re A/C to struggle in order to cool your home.
To solve this issue you can spray the outside unit with a garden hose gently. Remove the weeds that are growing around the AC unit, thus giving it room to breathe.
A Bad Compressor
This is the heart of an AC system; if the condenser is damaged; then the AC will not be able to cool your air. Replace the compressor if it has an issue, unfortunately it is uber expensive; therefore, unless you have a warranty for it, you will need to replace the entire outside unit.
A Broken Condenser Fan Motor
When you have a bad fan motor, this means that the AC system cannot cool your house; this is because the outdoor unit fan is not able to dissipate heat.
The refrigerant is the liquid which is able to absorb heat from your air. When you do not have refrigerant, then your AC is not able to absorb heat in order to cool air. When you have a low refrigerant level, this plainly means that you have a refrigerant leak. The following signs indicate a refrigerant leak;
- A bubbling or hissing noise
- When the A/C system is not able to cool your home especially on hot days; although, it cools your house on cool days and at night just fine.
- When there is an ice buildup outside and on the refrigerant line.
If you notice the signs above, turn off your AC and call a professional as soon as possible. This is because; running the AC at such a state can damage the compressor badly.
The above reasons are just some of the reasons why you’re A/C system is not cooling your home as required. It is always advised that you call a professional to come and have a look at it, in order for the problem to be solved.
