Air Conditioner Not Cooling

 A common question that is often heard of from homeowners across the United States in scorching summer months is “Why isn’t the air conditioner cooling my home!?” If you have fallen under the same misery, the first step that you should take to get rid of it is to schedule a service call with a repair service provider. The repair service provider will first gather the details of your problem and will try to troubleshoot it from a remote location. If it does not work, their technician will come to your site.

Let’s take a look at how a typical troubleshooting procedure works when the AC is not cooling.

 Firstly, they will ask you to check if there is no air coming out of the supply vents or just that it’s not cold. In case, no air is coming out, the second phase of the question becomes baseless. If no air is coming out then you will be asked to check the thermostat and fan setting. The thermostat should be set at cooling mode, a few degrees below the normal temperature to cool your house. The fan setting should be set to “auto” not “on”, which will cause your AC to blow air even if it’s not being cooled. If everything is fine with these or restoring them does not make a difference then you will be asked to check if the air filter is dirty. If it is clogged with dirt then the flow of air from your AC will be weak. This will compromise your comfort level immensely. A dirty air filter blocks airflow to the air handler. You have to clean or change it immediately.

 Next, the external cabinet of the air conditioner has to be checked. Sometimes it gets covered with dirt, dust or grass. Its breathing space is completely gone and it gets choked. Clean the dirt and trim plants if they are smothering the AC. In such conditions the outside unit can’t cool down the refrigerant to cool your home’s air.

 If this is not the problem, the technician on the other side of the phone will ask you to check the electric connections. Check the service switches on the compressor in the outside AC unit and at the air handler in the inside AC unit Take a look at the fuses or circuit breakers in the electrical panel. Sometimes fuses blow or breakers trip for the safety of the machine such as to prevent over heating thereby burning. A water sensor switch shuts off, if the water is crossing the danger level in the condensate pan. If none of these helped, your AC may be low on refrigerant. The latter could be due to refrigerant leak. However, a professional needs to come and check your machine and perform a possible repair.

 Here are reasons for not cooling AC at a glance:

• Low refrigerant charge
• Refrigerant not flowing
• Defective metering device
• Unclean device
• Bad reversing valve
• Faulty compressor valves
• Leaky ducts
• Blocked air filter
• Outdoor coils damaged or dirty
• Open windows
• Poor insulation
• Closed vents
• Humidifier is on
