Heat pumps are one of the best ways to stay warm in winter and cool in summer, especially with Christchurch’s ever-changing weather. But like any home appliance, they can sometimes run into problems. If your heat pump isn’t working as it should, don’t panic. Here are some of the most common issues people face, what causes them, and how to fix them (or when to call in the experts at Hiko Heating).
My heat pump isn’t blowing warm or cold air
Check that the unit is set to the right mode (heat or cool), and the temperature is set correctly. If that looks fine, the filters might be blocked. Dirty filters reduce airflow and make the unit struggle. Clean them every few months for best performance especially if you’re in a high-dust area or have pets.
My heat pump turns on but stops too quickly
This is known as short cycling. It could be due to a dirty filter, a faulty thermostat, or even an incorrectly sized unit. If your system keeps starting and stopping, it’s best to book a technician before it causes further wear and tear.
My heat pump is leaking water inside
If water is dripping from the indoor unit, the most common cause is a blocked drain pipe. Heat pumps remove moisture from the air when cooling, and if the water can’t drain properly, it can leak indoors. A regular heatpump service usually includes clearing this out.
I hear strange sounds like clicking, buzzing or rattling
Odd noises can be a sign of loose screws, fan problems, or electrical issues. If you hear buzzing, hissing or grinding, it’s best to switch off the system and call for help. Don’t wait until it breaks completely.
How often should I get my heat pump serviced?
Ideally, once a year or twice a year if your system works hard through both summer and winter. A service keeps things running smoothly and catches problems early.
My outdoor unit is covered in ice
Some frost on the outside unit is normal in winter, but if it’s completely frozen, that’s a problem. It might be a defrost cycle issue or poor airflow. Avoid chipping away at the ice, this can damage the unit. Book a professional heat pump check-up instead.
The remote isn’t working properly
First, check the batteries. If the screen is blank or buttons aren’t responding, replacing the batteries may solve it. Still not working? You might need a new remote or to reset the unit. Your local installer can help diagnose it quickly.
My energy bills have gone up
If your power bill has increased and you suspect your heat pump, it could be working harder than usual due to blocked filters, old refrigerant, or wear and tear. It might also be time to consider a heat pump replacement as newer models are far more efficient.
One room feels great, but the rest don’t
This is often an issue in bigger homes with one standard unit. A ducted heat pump solution or a multi-room system could solve the problem. Zoning options like Airtouch can give you control over each space,heating or cooling where you need it, not where you don’t.
