Greg offers the full package – from expert analysis and free, no-obligation, in-home energy audits, to expert installation, warranties he stands by, Flybuys and a range of payment options – and brings quality brands and products to a wide range of customers with different requirements.

It’s no secret that the Waikato can be a bit muggy and foggy so both new-home builders and renovators are keen to ensure their houses are well-ventilated – and this has seen the region become one of the highest users of Harrisons’ i-vent system, alongside high demand for solar, heat pumps and insulation.

So contact Greg and the Harrisons team today for a free, no-obligation, in-home energy audit – ask about our interest-free payment options, and regional council or finance card payment plans – and take the first step to a warmer, healthier, more energy-efficient future.


Here’s what the locals had to say...

Sara Dover


Extremely satisfied with our Harrisons solar install. Julie and Greg were fantastic and answered all our questions, nothing was too much trouble. Their install team were really professional and efficient and did a great job. I honestly can't find fault with anything. Really appreciated the after install visit to make sure we got the most out of our system and knew how to use the app.

David Hulme


Excellent product and support - very knowledgable and easy to deal with. Highly recommend Greg and the whole team.

Angela & Rex Brown


We are very pleased to have chosen Harrison’s Energy Solutions - Waikato to install our farm solar system. The service from start to finish was impressive, professional and personal. The installation team were well organised, clearly as the result of excellent communication from Greg and Julie. The post-installation visit was so important and as a result we have been able to monitor the system performance from day one. Our experience has changed the way we use our appliances and power consumption in general and consequently our monthly power account is a pleasure to receive. GO SOLAR.

Nicholas and Penelope Roberts


Honest, local, professional. Highly recommended.

David and Tina


The system you installed is exceeding our expectations and we are very happy.

Tom and Lailaa


We had Greg Foster install our solar system and it was done with ease and efficiency. However, the best thing has been Greg's after sales support. It's easy to sell something but it's the after sales input that really matters and here is where Greg has been fantastic - always available to answer quires and sorted out the initial teething problems without a fuss.

We are happy with the (Ventilation) system, from the day it was installed all our windows including the frames have been dry. The first morning Lesley was looking and saying they were still wet, having a closer look it was the outside that was wet.

It is so quiet we don't hear the fan working, in our old house with a HRV System we could always hear when it was working. While I was not here when it was installed, Lesley said they were very good, saying where they were putting the vents, putting down plastic sheets to catch any debris, all in all very professional.

Marie Rogers


Excellent service from Greg and his team (Denise is a super star), kept me well informed through out the whole process and all really great to deal with. Any questions answered quickly. Very impressed with the system I have received. Thank you very much for the great service and awesome system.

Ameil and Lucy


Thanks we are already enjoying our mositure free home. The mustiness has cleared up from the spare rooms which is amazing. Very impressed. Just hope that the summer kit works as well during the (hopefully) longe summer.



Absolutely toasty as. You & the installation guys have been very professional and done Harrison's Energy Solutions proud. I will recommend TEAM Harrison's to anyone who wants a heat pump. Thank you
