Air Conditioner Not Working

In Ottawa we encounter hundreds of air conditioner issues each year. The first question you need to ask yourself when you think there is something wrong with your air conditioner is if it is actually not working correctly. We often get asked by customers if their air conditioner is broken when in fact it is operating correctly. Here are a few signs that your air conditioner is actually not working as it should:


Warm air coming out of the vents – This is a pretty obvious one but if your thermostat is set correctly and the air conditioner is not blowing cold it indicates a problem with the cooling system.


Turning on and off constantly – Is your cooling equipment having frequent cycles? It should turn on and off fairly routinely and if it starts to deviate from this behavior then it can indicate an issue.


Bad smell – Another common indicator of an air conditioner not working properly is if a smell is coming from the equipment. This is typically an issue with mildew and can certainly indicate a service visit is in order. UV lighting equipment is a popular choice to help with odours.

Strange noises coming from the HVAC system – There are many different types of noise that can indicate an improper air conditioner operation. These noises can include things such as buzzing, whistling, and other loud noises.


Air Conditioner Troubleshooting Steps

Step One:


The first thing you should always check when having issues with your air conditioner is whether it is turning automatically or not. You can find this out quickly by ensuring that your thermostat is set to “cool”. Next, make sure that the temperature on the thermostat is set lower than the temperature in the home.


Have a look at your electrical connections – Is there a blown fuse? A tripped circuit? Is the power switch set to ON for your furnace and condenser?


Step Two:


Next let’s have a look at the blower unit. Sometimes an air conditioner gets clogged up, and does not put out enough air flow. To check this, go outside to your air conditioner housing. Check for damage to any blades or debris in the blower. Think about where your ducts might be pinched inside your home to prevent the flow of cool air.


Step Three:


If you are still having problems with your air conditioner, we recommend that you contact our experts at AirZone HVAC Services.

Air Conditioner Not Working Efficiently
There are many different aspects to consider when considering whether your air conditioner is not working efficiently. First, consider the age of your cooling unit. With technological advances air conditioners have become a LOT more efficient. In fact, a high efficiency air conditioner replacement cost can be significantly offset when replacing most 10 year old plus units. The second consideration is that your air conditioner is not working efficiently because of a problem. This is where you have a newer cooler that is not doing its job correctly. The most common cause for this is a blocked filter that is in need of replacement. High efficiency air conditioners can also lose efficiency because of outdoor issues around your outdoor unit. We recommend inspecting for plants and excess dirt that may be preventing airflow to restricting the fan from spinning easily. We commonly see plants that have grown too close to the unit. We recommend keeping a couple of feet clear all the way around to ensure proper airflow.
