It’s a hot summer day in St. Albert, and you’re looking forward to the relief that your air conditioner will bring you once you power it up. However, to your frustration, it’s blowing out warm air—making the hot, muggy day more insufferable and frustrating. Instead of the soothing, blissfully cold breeze it should be emitting, it’s recreating outside weather conditions inside your home.

If your air conditioner is blowing warm air, there may be something wrong with it. Fortunately, this is a common issue that is very solvable. Here are five tips for troubleshooting your air conditioner:

– Review Your Thermostat Settings

Before you panic, you’ll want to check your thermostat settings. Even though you’re confident that you hadn’t changed the temperature from your desired one, someone else may have adjusted it to suit their preferences and forgot to tell you about it. Ensure your air conditioner is set to Cool or Auto and not just “On,” causing the fan to run. Your air conditioner can also switch to Heat mode, which may be the culprit of the warm air it’s blowing out.

– Check Your HVAC System’s Air Filter

If nothing is amiss with your thermostat settings, you’ll want to inspect your system for a dirty air filter. The filter protects the delicate parts of your air conditioner from dust, dirt, and foreign objects to keep it running smoothly. However, when the filter is clogged with these substances, it will block the air conditioner’s airflow, making it harder to distribute chilly air.

It is best practice to inspect your air filter once a month and change it once it’s clogged. If you hold up your filter against the light and you can’t see through it, then it’s due for a change.

– Clean Your Condenser Coil

Similar to a bogged down air filter, your condenser coil may also be dirty, hampering your air conditioner’s performance. It can also obstruct the flow of cooled air and wreck your air conditioner when left unchecked. It’s best to have your air conditioner regularly maintained to ensure your condenser coil is clean, helping extend the life of your appliance. If your condenser coil is dirty, you’ll want to call AC repair near you to have it cleaned up in no time.

– Inspect Your Circuit Breaker

Another area you’ll need to check is the circuit breaker. Although an air conditioner blowing out warm air means that the power supply is working as it should, the outdoor unit or the condenser may be experiencing some power-related issues. Check your circuit breaker and reset it if it has tripped. However, if the breaker continues to trip, you’ll end up with a dangerous problem, which requires an HVAC company to solve.

– Call AC Repair Near You

Some problems are beyond your control, so it’s ultimately best to call a technician to repair your air conditioner. For example, your AC may be blowing out hot air due to a low refrigerant supply, indicating a refrigerant leak in your system. This particular situation isn’t something you can do by yourself, which means you’ll need to call a professional to assess the damage, repair it, and make recommendations to prevent it from happening again. Fortunately for you, they can maintain and repair your system in one go, giving you an air conditioner that will blow out the cool air you’ve been looking for!


Regularly maintaining your air conditioner is crucial to ensuring it performs as expected while extending its lifespan. It will also ensure that it gives you the much-needed relief of cold air on a hot summer day. By following these tips, you’ll find reliable refuge in your air conditioner!
