If your heat pump has not had a professional check in the last year, Heat Pump Servicing is a smart move for any Whanganui home. A regular service keeps your unit clean, efficient and reliable, and it helps spot developing faults before they become costly repairs. At GoFox Electrical Whanganui, we service and maintain heat pumps across Whanganui, Castlecliff, Gonville, Aramoho, St Johns Hill and Springvale, as well as Marton, Waverley, Taihape, Ohakune and Raetihi.
Our business is locally owned and run by Sotiris Grammaticogiannis, who was born and raised in Whanganui. Sotiris has more than a decade of experience with heat pumps and ventilation, so he knows how these systems behave in local homes. He also trains apprentices, which helps build the next generation of local electricians.
What Do You Get With Heat Pump Servicing?
A professional service covers far more than a quick filter wash. Our team works through both the indoor and outdoor units, then checks the whole system is running as it should. A typical service includes:
- Cleaning the indoor filters, coil and fan
- Clearing the condensate drain
- Checking the outdoor unit for debris, corrosion and damage
- Testing heating and cooling output
- Checking electrical connections and controls
- Looking for refrigerant leaks, worn parts and early signs of a fault
Once the job is done, we talk you through what we found. If something needs repair, you get a clear explanation and price before any extra work goes ahead.
Why Do Older Whanganui Homes Need Extra Attention?
Whanganui has plenty of character villas and bungalows, especially around Gonville, St Johns Hill and Durie Hill. These homes have real charm, but they can also be draughty and prone to damp. As a result, heat pumps in older homes often run longer and harder to keep rooms comfortable.
Damp air also affects the unit itself. Moisture inside the indoor unit can encourage mould on the coil and fan, which may cause musty smells when it starts up. A regular clean helps keep the air in your home fresher.
In addition, we can look at the bigger picture. Because we also install ventilation systems, we can advise on condensation and moisture control alongside your heat pump. For coastal homes in Castlecliff, we also check outdoor units for salt corrosion.
What About Holiday Homes in Ohakune and Raetihi?
Holiday homes and ski lodges near Ruapehu face a different challenge. These heat pumps can sit unused for weeks, then run flat out on cold winter weekends. During those quiet periods, dust, insects and even nesting pests can build up inside the unit.
For this reason, a service before the ski season makes a lot of sense. It means your heat pump is ready to warm the house quickly when you arrive, rather than letting you down on a freezing night.
How Often Do Whanganui Homes Need Heat Pump Servicing?
For most homes, we recommend one professional service each year. However, units in older or damp homes, busy households and holiday homes may benefit from more regular checks. Autumn is a great time to book, so your system is ready before the coldest months.
Between services, you can help by cleaning the indoor filters every few weeks during heavy use. It also helps to keep the outdoor unit clear of plants and garden clutter.
Call us sooner if you notice:
- Reduced airflow or slow heating
- Water dripping from the indoor unit
- Rattling, buzzing or grinding noises
- A musty smell when the unit starts
- Error codes on the display
- A rise in power bills with no clear reason

Frequently Asked Questions
Do you offer heat pump servicing and maintenance?
Yes. GoFox Electrical Whanganui services and maintains heat pumps across Whanganui and the wider region, including Marton, Taihape and Ohakune. Regular maintenance helps maintain airflow and performance. In addition, a professional service can identify wear or developing faults before they become bigger problems.
Why does my heat pump smell musty when it starts?
A musty smell usually points to mould or bacteria on the indoor coil or fan. This is common in damp homes, and a professional clean normally fixes it.
Should I service my holiday home heat pump before winter?
Yes. Units that sit unused can collect dust and pests. A service before the ski season helps make sure the system works when you arrive.
Can a heat pump help with damp in an older home?
A heat pump can help by keeping rooms warmer and drier. However, good ventilation also plays a big part, and we can advise on both.
Do you service heat pumps outside Whanganui city?
Yes. We cover Marton, Waverley, Taihape, Ohakune, Raetihi and surrounding rural areas.
