At Oria Heating and Cooling, we specialize in providing top-notch air conditioning installation services. Whether you’re replacing an old unit or installing a brand-new system, understanding the process can help you make informed decisions and ensure a smooth installation. In this blog, we’ll walk you through the steps involved in installing a new air conditioner in Oshawa.

1. Initial Consultation and Assessment

Understanding Your Needs

The first step in the installation process is understanding your specific cooling needs. During the initial consultation, our expert technicians will discuss your preferences, budget, and any concerns you might have. This conversation helps us recommend the best air conditioning system for your home.

Home Assessment

A thorough assessment of your home is crucial for determining the appropriate size and type of air conditioner. Our technicians will evaluate various factors, including the size of your home, the number of rooms, insulation levels, and the existing ductwork. This assessment ensures that the new unit will provide optimal cooling efficiency.

2. Choosing the Right Air Conditioner

Types of Air Conditioners

There are several types of air conditioners to choose from, each with its own set of advantages:

  • Central Air Conditioning: Ideal for cooling large homes, this system uses a network of ducts to distribute cool air throughout the house.
  • Ductless Mini-Split Systems: Perfect for homes without existing ductwork, these units offer flexible installation options and zoned cooling.
  • Window Units: Suitable for cooling individual rooms, these units are easy to install and relatively inexpensive.
  • Portable Air Conditioners: Versatile and movable, these units are great for temporary cooling solutions.

SEER Rating and Efficiency

Selecting an air conditioner with a high SEER (Seasonal Energy Efficiency Ratio) rating is essential for energy efficiency. Our team will help you understand the importance of SEER ratings and guide you in choosing a unit that balances efficiency and cost.

3. Obtaining Necessary Permits

Local Regulations

In Oshawa, installing a new air conditioning system may require permits to ensure compliance with local building codes and safety standards. Our team at Oria Heating and Cooling will handle the permit application process, ensuring all regulations are met.

Inspection Scheduling

Once the permits are obtained, we will schedule any necessary inspections with local authorities. These inspections ensure that the installation is performed correctly and safely.

4. Preparing for Installation

Pre-Installation Checklist

Before the installation day, our technicians will provide you with a pre-installation checklist. This checklist includes steps like clearing the installation area, ensuring access to electrical panels, and making sure any necessary repairs or modifications to existing ductwork are completed.

Equipment and Materials

We will also confirm that all required equipment and materials are ready for the installation. This includes the air conditioning unit, thermostat, refrigerant lines, and any additional components needed for a seamless installation.

5. Removing the Old Unit

Safe Removal

If you are replacing an old air conditioning unit, our team will safely disconnect and remove it. Proper disposal of the old unit is essential to ensure environmental safety and compliance with local regulations.

Inspecting Existing Infrastructure

After removing the old unit, our technicians will inspect the existing infrastructure, including ductwork, electrical connections, and the outdoor unit pad. Any necessary repairs or upgrades will be addressed before proceeding with the new installation.

6. Installing the New Air Conditioner

Positioning the Indoor Unit

For central air conditioning systems, the indoor unit (often called the evaporator coil) is typically installed in the basement, attic, or utility closet. Our technicians will position the unit to ensure optimal airflow and easy access for maintenance.

Installing the Outdoor Unit

The outdoor unit (condenser) is placed on a stable, level pad outside your home. The location is chosen to maximize efficiency and minimize noise. The unit is securely fastened to the pad to prevent movement and ensure proper operation.

Connecting Refrigerant Lines

Refrigerant lines are used to connect the indoor and outdoor units. Our technicians will carefully route these lines, ensuring they are properly insulated and secured to prevent leaks and improve efficiency.

Electrical Connections

Proper electrical connections are crucial for the safe operation of your new air conditioner. Our team will ensure that all electrical components, including the thermostat, are correctly wired and meet local codes and standards.

Installing the Thermostat

The thermostat controls the operation of your air conditioning system. Our technicians will install and configure the thermostat to ensure accurate temperature control and efficient operation. We can also recommend and install smart thermostats for enhanced convenience and energy savings.

7. Testing and Calibration

System Testing

After the installation is complete, our technicians will thoroughly test the system to ensure it is operating correctly. This includes checking refrigerant levels, airflow, and electrical connections. Any issues identified during testing will be promptly addressed.


Calibrating the system involves adjusting settings to achieve optimal performance. Our technicians will fine-tune the thermostat, airflow, and other components to ensure your home is evenly cooled and the system operates efficiently.

8. Final Inspection and Approval

Quality Assurance

At Oria Heating and Cooling, we take pride in our high-quality work. A final inspection is conducted to ensure that all aspects of the installation meet our stringent standards and that the system is performing as expected.

Customer Walkthrough

Before we consider the job complete, our technicians will walk you through the new system, explaining how to operate it and providing tips for maintenance. We will also answer any questions you may have and ensure you are completely satisfied with the installation.

9. Post-Installation Support

Warranty and Service Plans

We offer comprehensive warranties on all new air conditioning systems we install. Additionally, we provide service plans to keep your system running smoothly and efficiently. Regular maintenance is crucial for prolonging the life of your air conditioner and maintaining its performance.

Troubleshooting Assistance

Our commitment to customer satisfaction extends beyond the installation. If you encounter any issues with your new air conditioner, our team is always available to provide troubleshooting assistance and support.

10. Tips for Maintaining Your New Air Conditioner

Regular Maintenance

To keep your new air conditioner in top condition, schedule regular maintenance with Oria Heating and Cooling. This includes annual inspections, cleaning, and any necessary adjustments to ensure optimal performance.

Change Air Filters

Regularly changing the air filters is one of the simplest yet most effective ways to maintain your air conditioner. Clean filters improve airflow, enhance efficiency, and reduce the risk of breakdowns.

Monitor Performance

Keep an eye on your system’s performance and be alert to any changes in cooling efficiency or unusual noises. Early detection of issues can prevent costly repairs and extend the life of your air conditioner.

Keep the Outdoor Unit Clear

Ensure that the outdoor unit is free from debris, vegetation, and obstructions. This allows for proper airflow and helps maintain the system’s efficiency.

Use a Programmable Thermostat

Using a programmable or smart thermostat can help you optimize your cooling schedule and save energy. Set the thermostat to higher temperatures when you’re away and lower temperatures when you’re home to maximize efficiency.
