It’s an undisputed fact: heat pumps are the best way to keep an Auckland home comfortable year-round. They offer unparalleled performance when it comes to heating and cooling, making them a popular option among homeowners, new home builders, and environmentally-conscious consumers. However, one critical decision remains: should you install it yourself or hire a professional? Here at Air Conditioning Group, we appreciate and even encourage the Kiwi aptitude towards DIY. However, there are some problems that even the trusty toolbox can’t solve. This blog aims to help you decide when to do your own installation and when it’s best to leave things to the professionals. 


The Benefits of Heat Pumps 

Before diving into the installation methods, let’s quickly review why heat pumps are such a fantastic choice for your home. They provide efficient heating in the winter and cooling in the summer, helping you maintain a comfortable indoor environment without breaking the bank. Genesis Energy claims that heat pumps save Kiwis $500 a year on energy, not to mention, the health benefits are a great, often overlooked bonus.

However, to reap these benefits, proper installation is crucial. An incorrectly installed heat pump can lead to reduced efficiency, higher energy bills, and potential damage which defeats the whole purpose of getting a pump in the first place. 


DIY Installation

For those who enjoy tackling home improvement projects, installing a heat pump yourself can be an appealing option. Here’s a closer look at the pros and cons of this hands-on approach:

Pros of DIY 

  1. Cost Savings: The primary motivation for DIY installation is saving on labour costs. By doing the work yourself, you can potentially save hundreds or even thousands of dollars.
  2. Personal Accomplishment: Many DIY enthusiasts find the challenge and satisfaction of completing a complex task rewarding. Additionally, undertaking a project of this nature helps you develop and hone valuable skills that can be applied to future home improvement tasks.
  3. Flexibility: You can work at your own pace, fitting the project around your schedule. This is ideal for those who have busy lives and need to balance home improvement projects with other responsibilities.

Cons of DIY 

  1. Technical Skills Required: Installing a heat pump involves technical knowledge, including handling refrigerants, making electrical connections, and understanding HVAC principles. 
  2. Efficiency and Performance: Mistakes during installation can lead to reduced efficiency, higher energy bills, and potential damage to the system. 
  3. Costly Repairs: Improper installation can result in the need for professional repairs, which can negate the initial cost savings.
  4. Warranty Issues: Many manufacturers require certified professionals to install the system to maintain the warranty. If you install the heat pump yourself and something goes wrong, you might be left without warranty coverage, leading to out-of-pocket expenses for repairs or replacements.
  5. Local Building Codes: In Auckland local building codes are stringent, and failure to comply can result in fines or the need to redo the work. Additionally, handling refrigerants and electrical work poses significant safety risks.


Professional Installation

Opting for professional installation ensures that your heat pump is set up correctly and efficiently, providing peace of mind and optimal performance. Here’s a detailed look at the advantages and disadvantages of hiring professionals for this task:

Pros of Professional Installation

  1. Expertise and Experience: Our certified HVAC technicians bring a wealth of expertise and experience to the table. Their training and experience ensure that your heat pump is installed correctly, minimising the risk of errors that could affect performance.
  2. Adherence to Local Regulations: Professionals ensure your installation meets all Auckland regulations and safety standards. This compliance helps avoid potential fines and legal issues.
  3. Installation Warranty: Professional installation often includes a warranty on the work performed, providing added peace of mind. This warranty ensures that if any issues arise from the installation, they will be addressed at no additional cost.
  4. Optimal Performance: A correctly installed heat pump generally performs better and lasts longer. Professionals ensure that the system is calibrated and functioning at its best, which can lead to lower energy bills and fewer maintenance issues over time.

Cons of Professional Installation 

  1. Higher Upfront Cost: We’ll be transparent. Professional installation will cost more than DIY due to labour charges. However, this cost is often offset by the long-term benefits of a properly installed system.
  2. Availability of Professionals: Coordinating with a professional can sometimes lead to delays based on their availability. During peak seasons, such as the start of winter or summer, HVAC technicians can be in high demand.


Key Factors to Consider 

Still can’t decide which installation option to go with? Here is our step-by-step guide to determining what’s best for you: 

First, evaluate your own technical skills honestly. Heat pumps are complex systems, and there’s no shame in feeling overwhelmed or unsure. If you’re not confident in your ability to handle the technical aspects, professional installation is the safer choice.

Second, consider the short-term and long-term costs, including potential savings from reduced energy bills and fewer repairs with a professionally installed system. If you’re leaning towards the DIY route consider which tools you have and how much it would cost to purchase the correct ones. 

Next, look into your warranty coverage. Professional installation usually includes both a system warranty and an installation warranty, providing comprehensive protection. Additionally, proper installation can positively impact home insurance premiums.

Then, factor in the time commitment required for DIY installation versus the convenience of professional installation. Hiring professionals allows you to focus on other tasks and ensures the job is done quickly and efficiently. However, if you have a little extra time on your hands you might opt to install it yourself. 

Finally, we can’t overstate the importance of safety and legal considerations. Professionals adhere to local building codes and safety protocols, ensuring that all work is performed safely. This makes professional installation especially pertinent for commercial and other higher liability settings. 



At the end of the day, the best option won’t be the same for everyone. This is why it’s important to consider various factors when choosing between DIY and professional heat pump installation. However, for many Auckland homeowners, the benefits of professional installation—expertise, regulation compliance, use of specialised tools, and warranty coverage—outweigh the higher upfront cost.
