The Reversing Valve: How A Heat Pump Switches Between Heating And Cooling
Have you ever wondered how a heat pump can switch from heat to air conditioning and back again as the seasons change? Your heat pump’s ability to both heat and cool depends on one key component: the reversing valve. This part changes the direction of refrigerant flow inside your system.
In cooling mode, the refrigerant removes heat from inside your home. In heating mode, it reverses course, drawing warmth from the outdoor air and moving it indoors. If the reversing valve sticks or malfunctions, your system can’t switch directions — which means it may blow cool air even when it’s set to heat.
Problems with the reversing valve are one reason why you may find your heat pump to be struggling, but they’re not always to blame.
What To Do When Your Heat Pump Won’t Turn On In Heat Mode
If nothing happens when you switch to heating mode, the issue is often electrical or control-related. Here are some of the most common causes — and what you can do about them.
Tripped Breakers Or Power Issues
A surge or overloaded circuit may have cut power to your system. Check your home’s electrical panel and reset any tripped breakers that power your heat pump. If the breaker trips again soon after, leave it off and call a professional to inspect for electrical faults.
Thermostat Problems
If the thermostat isn’t sending the correct signal, the system won’t know to switch on. Make sure the thermostat is set to “heat” and the temperature is higher than your current room temperature. Replace the batteries if needed, or consider upgrading to a programmable thermostat for better reliability.
Wiring Or Capacitor Failure
These electrical components help start and regulate your system. When they fail, the unit may stay completely silent. Avoid touching or inspecting wiring yourself. This requires professional tools and training. Turn the system off and contact an HVAC technician to safely troubleshoot and replace any faulty parts.
More Possible Problems: Is Your Heat Pump Blowing Cold Air?
Sometimes, your heat pump powers on — but the air coming from your vents isn’t warm, despite it being set to heat mode. This typically points to a performance or mechanical issue, such as:
- Low refrigerant — Insufficient refrigerant means the system can’t effectively absorb or transfer heat.
- Dirty filter or coil — Restricted airflow makes it difficult to maintain warm temperatures.
- Blocked outdoor unit — Ice, leaves or other debris can reduce efficiency and prevent heating.
Even minor issues can worsen over time, so regular maintenance is the best way to prevent small problems from becoming costly repairs. If you have a heat pump that won’t heat when it should, give us a call. We’re happy to lend a hand.
How To Prevent Future Heating Problems
Heat pumps are durable, but regular maintenance is key to long-term performance. Seasonal tune-ups help to keep the reversing valve, coils and electrical components clean and efficient.
