Cooper & Hunter Air Conditioner Not Cooling

From time to time, Cooper & Hunter air conditioners can stop cooling the air they blow out

If your Cooper & Hunter air conditioner isn’t cooling or blowing cool air, the problem is most likely a clogged air filter or a faulty thermostat.

However, you don’t need to worry, as reading the causes and solutions below might help you solve the issue.

Possible Solution(s):

Thermostat

If your Cooper & Hunter air conditioner is blowing hot air, the thermostat may have been set to “heat” by mistake. If this is the case, it’s a simple remedy that you can do on your own.

Simply turn the thermostat to “cool” and observe if the air conditioner starts to blow cool air once more.

Check the thermostat and make sure it is set to “cool” and at the proper temperature. If it needs new batteries, replace them.

Dirty Filter

A dirty air filter can lead to a dirty evaporator coil, even though air filters have nothing to do with air temperature.

There may not be enough free airflow to allow for efficient cooling operation if the evaporator coil becomes blocked with dust and debris.

Debris build-up from a filthy air filter can cause frozen evaporator coils.

Although you may believe that “frozen” equals “cold,” the frozen coils actually obstruct the flow of cool air, causing warm air to flow from the running engine instead.

Depending on the environment, filter type, and home, air filter change should be done every 30-60 days by the owner.

Setting a monthly reminder to check the condition of your air filter is recommended.

Cooper & Hunter AC Not Blowing Air

If your Cooper & Hunter air conditioner turns on but doesn’t blow out any air, it’s likely to be a clogged air filter or defective thermostat.

Possible Solution(s):

  • Remove the filers with care and gently clean them, removing any dust on the filters.

  • To check if your AC fan is in working condition, open the unit and remove any debris inside the fan while fixing the loose axle. 
  • If the fan blades appear to be in working condition already, chances are the AC’s fan motor is broken.
  • To test it, open the unit and turn the fan manually.
  • If the fan rotates with resistance, you will need to replace the motor.

Cooper & Hunter AC Leaking

So, you discovered a puddle of water beneath your air conditioner. It’s vital to remain calm and figure out what’s causing the problem at this point.

Because there could be multiple causes, there is no one-size-fits-all answer to this question.

A clogged drain line is one of the most common causes of air conditioners leaking water. Dust and debris can accumulate and clog the drain hole. When the pan is full, the water has nowhere to go and begins to drip over the sides.

Below are the likely problem and solutions

Cause Result Solution
Full Drain Pan The drain pan has collected condensation to the brim and is overflowing with water. Clear the water from the drain pan clogged.
Clogged Line Dust Line Dust or debris is clogging the condensate drain line, causing water to back up into the A C unit. Use a chopstick to manually clear the drain line or remove it and use a burst of water to force the
obstruction out.
Dirty filters A clogged air filter will cause the air conditioner to freeze and drip as it thaws. To avoid this, clean the air filter regularly.
Frozen Evaporator Coil A dirty evaporator coil can freeze, causing the air conditioner to leak water as the ice melts. Use a can of compressed air or a long brush to clean the evaporator coils.
Refrigerant Leak Refrigerant liquid is leaking out of the AC. Unplug the AC unit and contact an HVAC technician.

 

Possible Solution(s):

Full Drain Pan

It is simple to repair an air conditioner that is leaking water from its drain pan.

Simply drain the condensation that has accumulated in the drain pan to get your AC back up and running.

When your drain pan becomes full, schedule a routine to drain the water before it overflows.

This is most appropriate for portable and floor air conditioners.

Clogged Drain Line

One of the most common causes of air conditioner water leaks is a clogged drain line.

Dust and debris can collect in the drain hole and clog it.

When the pan is full, there is nowhere for the water to go, and it begins to drip over the sides.

Use a chopstick to manually clear the drain line or remove it and use a burst of water to force the obstruction out.

Dirty Air filter

Leaking water is one of the problems caused by dirty air filters in your air conditioner.

If the filter is clogged, the appliance may freeze and leak water as the ice melts.

The dust on the filter can also travel through the drain line and cause clogs, allowing water to back up into your AC unit.

Remove the filter and clean it gently with soap and water.

Allow the ice to melt if the filter is frozen, and then gently scrub the air filter mesh with a soft brush.

Let the filter dry before reinstalling it in your air conditioner.

Frozen Evaporator Coil

A dirty evaporator coil, like a dirty filter, will cause the air conditioner parts to freeze, resulting in water leaks as the ice melts.

An air conditioner leaking water inside your home indicates a frozen AC, especially if the unit leaks as it is turned off.

To avoid further damage, allow the ice to melt before cleaning the evaporator coil.

Refrigerant Leak

The water leaking from your air conditioner could be refrigerant. If you hear a bubbling noise and see a small leak that has iced up, you most likely have refrigerant leaks.

If you suspect your air conditioner is leaking refrigerant, contact a licensed HVAC technician right away because touching or inhaling freon can irritate your skin and lungs.

Avoid staying in the same room as a liquid or gas refrigerant leak, and if you suspect a refrigerant leak, turn off the air conditioner immediately.

Aside from the causes listed above, other reasons why air conditioners leak water include a faulty condenser pump or an incorrectly installed unit.

Some of the solutions listed above require the services of a qualified HVAC technician, so it is best to call an HVAC to get your AC back up and running.
