A heat pump that stops working properly is more than an inconvenience, especially when the temperature drops across the Welsh borders. The good news is that most faults have clear warning signs, and many are simple to fix when caught early. At Green Flow Heat Pumps, our Heat Geek certified engineers carry out heat pump repairs for homes and businesses in Presteigne and right across Builth Wells, Hay-on-Wye, Hereford, Leominster and Llandrindod Wells. Below, we explain the most common problems we see and when it’s time to call in an expert.
Why Heat Pumps Develop Faults
Heat pumps are reliable, but they’re still machines with moving parts. Over time, fans wear, filters clog and settings drift. In addition, a system that was poorly designed in the first place often struggles, no matter how new it is. That’s why so many heat pump repairs we carry out actually start with fixing how the system was set up.
6 Common Heat Pump Problems
1. The House Isn’t Getting Warm
This is the complaint we hear most. It could be low refrigerant, incorrect flow temperatures or a faulty sensor. Equally, radiators that are too small for the room can leave you feeling chilly.
2. Strange Noises From The Outdoor Unit
A low hum is normal. Grinding, rattling or loud clicking, on the other hand, usually points to a worn fan motor, loose panels or a compressor issue.
3. Ice Building Up On The Unit
Light frost in winter is expected, and the system will defrost itself. However, if thick ice stays on the coil for hours, the defrost cycle may have failed.
4. Error Codes On The Controller
Most systems display a code when something goes wrong. While it’s tempting to keep resetting it, a repeating code means a fault needs proper attention.
5. Water Leaking Around The System
Some condensation is perfectly normal. Even so, puddles indoors or near the cylinder could mean a blocked drain, a split pipe or a failed valve.
6. Higher Running Costs Than Usual
If your electricity use creeps up while comfort goes down, the system is working harder than it should. Often, this is an early sign that heat pump repairs will soon be needed.
Quick Checks Before You Book Heat Pump Repairs
Before picking up the phone, a few simple checks can save time:
-
- Make sure the thermostat and controller are set correctly
-
- Check the power supply and any tripped switches
-
- Clear leaves, snow or debris from around the outdoor unit
-
- Look at the system pressure gauge, if you have one
If none of these sorts the problem, then it’s time to call a qualified engineer. Please don’t open the unit or touch refrigerant parts yourself, as this can be dangerous.

How Regular Servicing Prevents Costly Breakdowns
Many faults that lead to heat pump repairs can be spotted during an annual check. Our heat pump servicing looks at refrigerant levels, electrical connections, controls and flow rates. As a result, small issues get fixed before they turn into a cold house in January.
Repairs For Homes & Businesses
For homeowners, a breakdown means cold rooms and no hot water. For businesses, though, it can mean unhappy staff, closed rooms or guests complaining. Because of this, we treat every call-out with the same urgency. Our engineers diagnose the root cause rather than just clearing the symptom, so the same fault doesn’t keep coming back a few weeks later.
