What Does an HVAC Inspection Include?

During an HVAC inspection, a certified technician will thoroughly examine all the major components of your system. Here’s what typically happens:

HVAC System Overview

The technician will visually inspect the entire HVAC system, looking for signs of wear and tear or potential issues.

Check of the Moving Parts

All moving parts, such as fans and belts, are inspected for wear and lubricated as needed to ensure they’re running smoothly. This helps prevent breakdowns and extends the life of the equipment.

Thermostat Calibration

The thermostat is checked for accuracy to ensure it’s regulating the temperature in your home properly. An improperly calibrated thermostat can lead to inefficient heating or cooling.

Electrical Component Inspection

The technician will inspect electrical connections and components to ensure everything is secure and functioning correctly. Faulty electrical connections can be a safety hazard and may cause system failures.

Air Filter Replacement

Air filters are examined and replaced if necessary. Clean air filters are essential for maintaining indoor air quality and ensuring the system runs efficiently.

Refrigerant Level Check

For air conditioning systems and heat pumps, refrigerant levels are checked and adjusted if needed. Low refrigerant levels can reduce cooling efficiency and damage the compressor.

Heat Exchanger and Burner Inspection

In furnace inspections, the heat exchanger is inspected for cracks, and the burners are cleaned to ensure efficient operation. A cracked heat exchanger can lead to dangerous carbon monoxide leaks.

System Safety Checks

Built-in safety features, such as emergency shutoffs and pressure switches, are tested to ensure they're functioning properly.

Optional Testing

Finally, the system is run through a full operational test to ensure it starts, runs and shuts off correctly. The technician will also listen for unusual noises that could indicate a problem.

Why Do You Need HVAC Inspections?

Regular HVAC inspections are essential for several reasons:

Preventive maintenance. HVAC inspections help catch small issues before they become major problems, reducing costly repairs or system replacement.
Energy efficiency. A well-maintained HVAC system operates more efficiently, resulting in lower energy bills.
Extended equipment life. Regular maintenance extends the life of your HVAC equipment, providing better value for your investment.
Safety. HVAC inspections can identify potential safety hazards, such as faulty electrical connections or cracks in the heat exchanger, ensuring your home is safe.
Comfort. HVAC inspections ensure your system is working properly, making your home comfortable year-round.

How Long Does an HVAC Inspection Take?

An HVAC inspection typically takes between one and two hours, depending on the size and complexity of your system. Larger or more complex systems may take longer, while smaller, simpler ones can be inspected more quickly.

How Often Should You Inspect Your HVAC System?

It’s generally recommended to have your HVAC system inspected at least once a year. Ideally, you should schedule a furnace inspection twice a year, once before summer starts and once before winter sets in. Similarly, you should schedule an inspection of your air conditioner before and after the peak seasons.

How Much Does an HVAC Inspection Cost?

The cost of an HVAC inspection can vary, but you can expect to pay between $150 and $500 (CAD 206 and CAD 688) for a standard inspection, according to data from HomeGuide.

Additional Considerations

DIY Vs. Professional HVAC Checkups

While there are some basic maintenance tasks you can perform yourself, such as changing air filters, it’s important to have a professional HVAC technician conduct a thorough inspection. They have the expertise and tools to identify and fix issues that may not be apparent to the untrained eye.

Seasonal HVAC Inspections

Scheduling inspections before the major heating and cooling seasons start can help avoid emergency repairs and ensure your HVAC system operates at peak performance when you need it most.
