Heat Pump Repair in Gatineau and the Outaouais
Heat pumps rely on a defrost cycle, a working compressor, and correct refrigerant charge to deliver both heating and cooling, so when any of those falter the symptoms can look like error codes, ice buildup on the outdoor unit, or heating and cooling capacity that has quietly dropped off. We service ductless and central heat pump systems throughout Gatineau, Hull, Aylmer and surrounding areas. Call 819-800-6457 with the model and any code shown on the indoor unit.
Error codes on the indoor unit
Most manufacturers use blinking lights or a digital code to point to a specific fault, from a communication error between indoor and outdoor units to a sensor or pressure switch problem. Reading and noting the code before calling helps us prepare for the visit.
Persistent icing on the outdoor unit
A light frost during a normal defrost cycle is expected in cold weather, but heavy ice that does not clear points to a failing defrost board, a blocked fan, low refrigerant, or a reversing valve that is not switching properly.
Weak heating or cooling capacity
A heat pump that used to keep up but now struggles in the same outdoor temperatures may have a refrigerant leak, a dirty coil restricting heat exchange, or a compressor that is losing efficiency.
Fan and compressor issues
A noisy or seized outdoor fan reduces heat exchange and can trigger high-pressure faults, while compressor problems usually show up as short cycling, tripped breakers, or a unit that runs constantly without reaching setpoint.
How it works

- 02
Phone assessment
We narrow down likely causes and confirm whether a technician visit is the right next step.
- 03
On-site testing
The technician checks refrigerant pressures, electrical components, defrost operation, and airflow on both indoor and outdoor units.

Findings and options
You receive a clear explanation of the fault before deciding on repair.
Frequently asked questions
Is ice on my outdoor unit always a problem?
A thin layer of frost that clears during a normal defrost cycle is typical in cold, humid weather. Thick ice that builds up and does not melt, or ice that forms even in mild temperatures, usually means the defrost cycle is not working properly.
What does an error code on my ductless unit mean?
Codes vary by brand but generally point to a specific sensor, communication, or pressure fault. Note the exact code or count of blinks so we can be better prepared when we arrive.
Can a heat pump be repaired in winter?
Yes, outdoor units are designed to be serviced in cold weather, though some refrigerant work may be limited by outdoor temperature. A technician can assess this on site.
My heat pump heats fine but will not cool in summer, or the reverse. Why?
This can point to a reversing valve that is stuck in one position, which affects the direction of refrigerant flow between heating and cooling modes.
Do you service both wall-mounted and central heat pumps?
Yes, we repair ductless wall-mounted heads as well as central, ducted heat pump systems.
