As a Canadian homeowner, air conditioning is essential for keeping your home comfortable during the summer months. However, if your AC unit is struggling, it can lead to higher energy bills, reduced comfort, and even system failure.

In this article, we’ll discuss five key indicators of a struggling air conditioning unit and what you can do about it.

1. Reduced Airflow

Reduced airflow is one of the most common signs of a struggling AC unit. If you notice that your air conditioner is blowing weak or warm air, it could be a sign that your AC unit is struggling. This could be due to a number of issues, such as a clogged air filter, a faulty blower motor, or a refrigerant leak.

To address reduced airflow, start by checking your air filter. If it’s clogged, replace it with a new one. If this doesn’t solve the problem, it’s best to call a professional to diagnose and repair the issue.

2. Strange Sounds

If your air conditioning unit is making strange sounds, it could be a sign of a struggling system. These sounds may include grinding, squealing, or banging noises. These sounds can be indicative of a number of issues, such as a loose belt, worn bearings, or a damaged compressor.

If you notice any strange sounds coming from your AC unit, it’s best to call a professional to diagnose and repair the issue. Ignoring strange sounds could lead to more serious and costly issues down the line.

3. Higher Energy Bills

If you notice a sudden increase in your energy bills, it could be a sign that your air conditioning unit is struggling. As your AC unit becomes less efficient, it will have to work harder to cool your home, leading to higher energy bills.

To address higher energy bills, start by checking your air filter and cleaning your vents. If this doesn’t solve the problem, it’s best to call a professional to diagnose and repair the issue.

4. Foul Odours

Foul odours coming from your air conditioning unit could be a sign of a struggling system. These odours may include a musty or mouldy smell, which can be indicative of mould growth in your ducts or air filter.

To address foul odours, start by replacing your air filter. If the odour persists, it’s best to call a professional to diagnose and repair the issue.

5. Short Cycling

Short cycling is when your air conditioning unit turns on and off frequently, rather than running in longer cycles. This can be indicative of a number of issues, such as a faulty thermostat, a refrigerant leak, or a clogged air filter.

To address short cycling, start by checking your air filter and cleaning your vents. If this doesn’t solve the problem, it’s best to call a professional to diagnose and repair the issue.

Final Thoughts

If you notice any of these signs of a struggling air conditioning unit, it’s important to address the issue as soon as possible. Ignoring these signs could lead to more serious and costly issues down the line. By taking proactive measures to maintain your air conditioning unit, you can improve its efficiency, reduce energy bills, and ensure that your home stays comfortable throughout the summer months.
