The cost of a residential ducted system can range from $8,000 to $18,000, while commercial HVAC projects can cost between $150 and $400 per square meter of conditioned space. These costs are influenced by factors such as the complexity of the project, the materials used, and the location.
Regional Variation in HVAC Pricing
HVAC engineers in major cities such as Auckland and Wellington tend to charge higher rates than those in regional centres. This is due to factors such as higher costs of living and a greater demand for services. Homeowners in regional areas can expect to pay lower rates, but may also face longer wait times for services.
Licensing and Certification
When hiring an HVAC engineer, it's essential to ensure they hold the necessary licenses and certifications, such as a Refrigerant Handling Certificate and an REW (Registration of Electrical Workers) license. This ensures that the work is done safely and to a high standard, and can also impact the pricing of the project.
