How to Turn Your AC On For the First Time After Winter

After months of non-use, your air conditioner may not work correctly, leading to costly repairs or a complete breakdown. That’s why turning on your AC securely after winter is crucial. If you live in Hamilton, ON, and need professional AC service, B & G Heating Air Conditioning & Ventilation is here to help you with all your AC-related needs.

Steps to Follow to Turn On Your AC After Winter

  • Check Your Air Filter

The air filter is one of the vital components of your AC unit. It traps dirt, dust, and other particles, preventing them from circulating throughout your home. If your air filter is dirty or blocked, it can restrict airflow, reduce efficiency, and cause your AC to work harder than necessary. Therefore, before turning on your AC, it’s essential to check your air filter and replace it if necessary.

To check your air filter, do the following:

1. Locate the filter compartment on your AC unit, usually in the return air duct.

2. Carefully remove and inspect the filter for dirt, dust, and debris.

3. If the filter is dirty or blocked, replace it with a new one.

Depending on usage, changing your air filter every 30 to 90 days is recommended.

  • Inspect Outdoor Unit

The outdoor unit is essential for your air conditioning system but can get damaged due to weather and other factors. Therefore, it’s essential to check it before turning on your AC after winter. Clear any debris around it, check for visible damage like dents or rust, and ensure enough clearance for proper airflow. If you’re not confident in inspecting it, consider scheduling an air conditioning service in Hamilton, ON. Routine maintenance can prevent costly repairs and extend your system’s lifespan. If you notice any problems, get a professional air conditioning service like B & G Heating, Air Conditioning & Ventilation.

  • Check Thermostat Settings

Before turning on your AC:

1. Make sure that your thermostat settings are correct.

2. If you have a programmable thermostat, ensure it is set to your desired temperature and schedule.

3. If you have a manual thermostat, adjust the temperature accordingly.


  • Turn On AC

Once you have completed the above steps, it’s time to turn on your AC. Set your thermostat to your desired temperature and turn on your AC unit. Allow your AC to run for a few minutes and ensure that cool air comes from your vents.

  • Monitor your AC

After turning on your AC, monitoring it for the first few hours is essential to ensure it is running correctly. Check your vents to ensure that cool air is flowing and the airflow is steady. Listen for any unusual sounds from your AC unit and look for any signs of water leaks. If you notice any issues, contact us immediately for emergency AC repair in Binbrook.
