Air Conditioner Not Cooling 8 Reasons

It’s something we’ve all experienced. Sweating through a restless night or struggling through a hot July afternoon. It’s inconvenient when your air conditioner fails to chill, but it does happen. And it won’t be in the dead of winter when it does. It will be the hottest day of the summer, and no matter how many times you turn down the thermostat, the Air Conditioner will still not be pumping cool enough air.

Air conditioning systems are more than just the condenser unit (the AC unit or heat pump) that sits outside your house. An interior air handler unit (furnace or fan coil), an evaporator coil, an air filter, a thermostat, and copper tubing (refrigerant lines) that connect the indoor and outdoor units are all moving parts of a standard split-system air conditioner.

So there are various solutions to the query, “Why isn’t my air conditioner cooling the house?” But don’t be concerned. Simply because your system isn’t cooling does necessitate expensive Ac Repair in Bengaluru Services or the replacement of the entire system.

Some Reasons Why Your Air Conditioner not cooling

Dirty cooling coils

If any of these coils have a film of dirt on them, heat transmission between the coils and the air pushed over them becomes significantly more difficult.

Refrigerant leak

If your system has a refrigerant leak, it will be unable to transport heat out of your home effectively. Your air conditioner will run, but it will not offer you ideal comfort.

Blocked condenser unit

If your condenser unit is clogged, it will be unable to expel heat from the condenser coils effectively.

Dirty air filter

When your air filter is clogged, the amount of air that can pass over your evaporator coils is reduced.

Problems with the compressor

Your air conditioner’s compressor is in charge of ensuring that the refrigerant is at the proper pressure, making it one of the most crucial components of your machine. If it begins to fail, your air conditioner will be unable to adequately chill your house.

Old System

When an air conditioner approaches the end of its useful life, it will no longer be able to chill your house as effectively as it once did.

Incorrect thermostat settings 

If your thermostat’s fan setting is set to “on,” your air handler will blast air even when your system isn’t cooling. As a result, part of the air coming through your vents will be heated.

Power issue 

This may seem obvious to you. However, that might be one of the reasons why your air conditioner isn’t working.

How to troubleshoot the problem?

1. Check your thermostat 

If your air conditioner isn’t cooling. Replace the batteries in the thermostat, even if you’ve just done so. Examine the circuit breaker to which the thermostat is attached if it is powered by your home’s electrical supply.

Check to see whether you’ve recently relocated your thermostat. If this is the case, you may have put it in an inconvenient area where it cannot obtain an accurate temperature measurement in your house.

The thermostat will need to be relocated, preferably away from windows and vents.

2. Examine for Leaks

When it comes to an air conditioner that isn’t cooling properly, refrigerant leaks are a prevalent cause. A hissing sound emanating from the unit, frozen coils, and an air conditioner fan that is blowing but not chilling are all signs of a refrigerant leak. You should also inspect the problem from Ac Repair in Bhopal professionals to clean your AC drain pipes to prevent leaks from the outside.

3. Make Humidifier Adjustments

If you have a humidifier in your house, it might be the cause of your air conditioner not cooling adequately.

If the humidifier runs too hot, it will wipe out the cooling produced by your air conditioner. As a result, even if your air conditioner is operating normally, you will feel warmer in your house.

If you feel this is the problem, turn down the humidity to see if it makes a difference. You may also try shutting off the humidifier entirely if you don’t need it for anything special.

4. Examine the Filter

Checking your air conditioner’s filter is another simple task that you can perform without the assistance of a professional. A clogged filter restricts airflow, preventing your air conditioner from effectively blowing cold air. Some air filters must be updated once a month. If you haven’t checked on it in a while, now is an excellent opportunity to do so.

Scheduling maintenance can help you avoid costly repairs!
