How to Check Your Air Conditioner Before Calling for Service

Of course, this would be the hottest day of the year that your air conditioner stopped working! Serving this can be costly, and you just need to swear when waiting for a service technician. or do you? Check these steps that may save some money, and at the same time can help keep you calm!


Assess the problem. Is the unit not working only, is it not heating the air, or is it just flowing around hot air?

It is not working at all: condenser (for an external unit) or an air handler / indoor unit is not running.

Make sure it is plugged in. It may seem obvious, but there are occasions when it is a problem at all. Whether an accidental tap with a child, dog, or vacuum cleaner, the plug may be partly or completely disorganized.

Check the circuit breaker and fuses. Make sure they are in the right place, are working and are working properly. Circuits are easily overloaded, especially with older homes, if the air conditioner shares with a circuit such as iron, refrigerator, or microwave.

Check your thermostat (cooling control) and make sure it is set to cool at the current temperature, and is working properly. With plugs, sometimes settings can change with a crash.

Check your fan blower belt for excessive dull, damage, or breakage. This can cause less air flow which allows for ice making, and thus causes less cooling performance.

Repair or replace the blower belt. Let the ice melting before restarting the AC unit.

Check the coils and filters. If they are ripe with dust and debris, clean them well. Make sure that you have melted any ice before resuming your unit.

Call for service. If you have verified that everything is connected, operated, set up properly, and is clean, it may be time to call the service department.

Preventative Maintenance

Wash your condenser coil during the season or as needed. Turn off your air conditioner, get a garden tube, and spray a coil using an up-and-down pattern. Be especially careful if your condenser is close to a dryer vent, or if your neighborhood is full of cotton trees. These two items are “air conditioner killer”.

Clear or change your filter regularly. This simple step alone can increase the efficiency of your air conditioner alone. It will also work less, which will increase the life of your device

There is a good indication that your filter needs to be changed, the fact of making ice inside your cooling unit (evaporator section).

It can be difficult to see that the unit has been sealed, but touch the outer metal and feel the noticeable temperature difference. You can also see the snow on the large line leading to the outer unit (suction line).

If ice is formed, it is possible that your air filter is severely dirty and your normal air flow is restricted. This allows the creation of ice due to the fact that not enough heat is being offered in your cooling section.
