Ways to Check Whether AC is Cooling or Not?
The very first step to check AC is cooling or not is ro feel the air coming out of the vents. If the air feels warm or tepid, then it is likely that the AC unit is not cooling properly.
Another way to check the cooling of your AC unit is to measure the temperature of the air coming out of the vents with a thermometer. The temperature should be lower than the temperature of the room in order for the AC unit to be working properly.
If you notice that your AC unit isn’t cooling properly, then you should check the listed possible reasons and solutions.
Possible Reasons Why AC is Not Cooling & Solutions:
Air conditioners are a godsend during hot summer days. However, when they stop working properly, it can be a nightmare. If your air conditioner is running but not cooling the house, there are a few things you can check before calling a professional.
1. Thermostat is set incorrectly
One of the most common reasons if your AC is not cooling is that the thermostat is set incorrectly. The thermostat controls the temperature of the room by turning the AC unit on and off. If it is set too low, the AC unit will run continuously without ever reaching the desired temperature.
On the other hand, if the thermostat is set too high, the AC unit will turn off before the room has cooled down.
Solution: To fix this problem, simply adjust the thermostat to the correct setting. If you’re not sure what that is, consult your owner’s manual or contact a professional AC technician.
2. The filters are dirty
When your AC is not cooling properly, another thing you should check is the filters. Over time, they can become clogged with dust, dirt, and other debris, which can block airflow and prevent the unit from working properly.
Solution: In some cases, you may be able to clean the filters yourself. However, if they are excessively dirty or damaged, you may need to replace them. Depending on the type of filter, this can be an easy and inexpensive fix. So, if your AC unit is not cooling as well as it should be, be sure to check the filters and clean or replace them as needed. Cleaning a window AC is different than cleaning a split AC, do have a look at the different methods to make sure your AC is functioning properly.
3. The condenser unit is blocked
If your condenser unit is blocked, your air conditioner will not be able to properly cool your home. The condenser unit is responsible for releasing heat from the refrigerant, so if it is blocked, the heat will build up and prevent the refrigerant from cooling properly. In addition, a blocked condenser unit can cause the compressor to overheat and shut down.
Solution: If you notice that your air conditioner is not cooling properly, check the condenser unit to make sure it is not blocked. You may need to remove debris, dirt, leaves, or anything else that’s blocking the unit. In extreme cases, you may need to call a professional to clean or replace the unit.
4. The heat pump is damaged
A heat pump is an essential part of an AC system, and when it’s damaged, the AC will not be able to effectively cool your home. The heat pump is responsible for moving heat from the inside of your home to the outside, and when it’s not working properly, that process is disrupted. As a result, your home will likely be warmer than usual, and your AC unit will have to work harder to try to reach the desired temperature.
In some cases, the AC may even shut off entirely due to heat pump damage.
Solution: If you suspect that your heat pump is damaged, it’s important to call a qualified AC repair technician as soon as possible. A technician will be able to diagnose the problem and recommend the best course of action. In many cases, heat pump damage is caused by a lack of maintenance.
If you haven’t had your heat pump serviced in a while, it’s important to do so as soon as possible. A qualified technician will be able to clean the unit and check for any signs of wear and tear. If you have an older heat pump, it’s also a good idea to replace it with a newer model. Newer heat pumps are more efficient and can help you save money on your energy bills.
5. The evaporator coil is frozen
One of the most common reasons if your AC is not cooling is the frozen evaporator coil. The coil is responsible for absorbing heat from the inside of your home, and when it gets too cold, the coil can actually freeze over. There are a few different reasons why this might happen, but the most common is low refrigerant levels. When the refrigerant level is low, it can cause the coils to get too cold, which leads to ice buildup.
Another possible reason for a frozen evaporator coil is a dirty air filter. A dirty air filter can restrict airflow to the coils, causing them to get too cold. Lastly, a faulty blower motor can also cause the evaporator coils to freeze.
Solution: If you suspect that your evaporator coils are frozen, you should call a professional AC repair technician to have them inspected and repaired.
6. The compressor is malfunctioning
If your AC isn’t cooling, it could be because the compressor is malfunctioning. In order for the AC to work, the compressor needs to be working properly. The compressor helps to circulate the refrigerant through the AC unit.
If the compressor is not working, it could be because it is not getting enough power, there is a problem with the airflow, or there could be a leak in the system.
Solution: If you think that the compressor is not working properly, you should call a technician to come and take a look at it. They will be able to diagnose the problem and get your AC unit up and running again.
7. The refrigerant is leaking
If your AC is no longer cooling your home effectively, it may be due to a refrigerant leak. Refrigerant is essential for the AC unit to function properly, and a leak can cause the unit to run less efficiently and even break down entirely.
Solution: There are a few ways to tell if you have a refrigerant leak. One is if you notice ice or frost buildup on your AC unit. Another is if your AC unit is making strange noises or emitting a foul smell.
If you suspect that your AC unit has a refrigerant leak, it’s important to have it checked out by a professional as soon as possible. Otherwise, you may find yourself dealing with an expensive repair bill or even having to replace your AC unit entirely.
8. Your AC is undersized
If your AC isn’t cooling, one possibility is that it’s undersized for the space it’s supposed to be cooling. This is a surprisingly common problem. Many people don’t realize that there are specific AC sizing calculations that need to be done in order to ensure that an AC unit is properly sized for the space it will be cooling.
An undersized unit will struggle to cool a space and will often lead to poor indoor air quality and high energy bills.
Solution: If you think your AC unit may be undersized, the best course of action is to consult with a qualified HVAC contractor who can help you determine the proper size unit for your needs. This article on how to calculate room size for AC can also help you.
How to Increase AC Cooling in the Room
When it’s hot outside, the last thing you want is for your air conditioner to struggle to keep your home cool. Fortunately, there are a few things you can do to help your AC run more efficiently and effectively to cool your home.
1. Keep the area around your AC unit clear and free of debris
If you want your AC unit to work at peak efficiency, it’s important to keep the area around it clear and free of debris.
