Hiring a handyperson might seem cost-effective, but HVAC inspections require specific training and licensing that most handypersons do not have. Without the right experience, tools, or knowledge of local codes, a handyperson may not properly diagnose or repair issues. This can lead to incomplete repairs, voided warranties, or safety hazards.
Only consider a handyperson for very minor, non-technical HVAC tasks, not for system inspections or repairs involving electrical or refrigerant components. For comprehensive inspections, always choose a licensed HVAC technician near you.
Licensed HVAC technicians follow a structured approach to inspecting your system:
They begin by checking the entire system, including both indoor and outdoor components, for visible damage or wear.
The technician confirms that your thermostat reads and responds accurately, then examines air filters, ductwork, and cleans accessible parts.
They assess refrigerant levels and check electrical connections for safety.
Finally, they evaluate fans, motors, and safety controls.
Once issues are found, the technician recommends repairs, cleaning, or replacements as needed.
The cost of an HVAC inspection ranges from $100 to $650, depending on your unit’s size, any underlying issues, and whether emergency service is required. Inspections for larger or more complex systems, or those needed on short notice, often fall at the higher end of this range.
Routine checks cost less, whereas urgent diagnostic or repair services can increase the total price. Always request an estimate from your HVAC technician before work begins so you can clearly understand your investment.
