Why Your Heat Pump Isn’t Switching to Cooling Mode

As the temperatures are warming up, you may be ready to switch your heat pump over from heating mode to cooling mode. But after a long winter season, sometimes your heat pump can get stuck and struggle to switch back to cooling.

The good news is, there are a few things that you can troubleshoot on your own before giving us a call for heat pump service in Egg Harbor Township, NJ.

Keep reading to learn more about why your heat pump isn’t switching to cooling mode and what you can do about it. If you can’t solve the problem on your own, you’re always welcome to give us a call and we will come out and do a thorough inspection of your system. We won’t just fix the problem, we’ll help you figure out the root cause and hopefully prevent it from happening again in the future. 

Thermostat Settings

When you want to change the temperature in your home or switch between heating and cooling, you use your thermostat to do so. The first thing you want to check is that your thermostat has the correct settings selected.

Maybe you thought you switched over to cooling mode, but you didn’t. Or maybe you thought you lowered the temperature, but you didn’t. Double-checking these simple things can save you a headache if that’s what’s wrong. 

Reversing Valve

Your heat pump also has a reversing valve that allows it to switch between heating and cooling. It’s what makes a heat pump so unique. It’s heating and cooling all in one. But sometimes this reversing valve can break or get stuck in one mode or the other. It’s completely normal for this component to wear down over time and need to be repaired or replaced.

If you try to troubleshoot and locate your reversing valve so that you can take a look at it, you may be tempted to just manually move it over into cooling mode. This may work as a short-term solution, but there’s still a problem that needs to be fixed. When winter rolls around again and you need to switch back to heat, the reversing valve may malfunction again. There’s also a chance that it could break off completely if it’s stuck in one position.

If you can’t pinpoint an exact problem, there is still a chance that your thermostat is not properly connected to your heat pump. It could be that your thermostat batteries are low, or the system is miscalibrated. If you check your thermostat settings and reversing valve and still can’t figure out what is wrong, our team can take a closer look. We can troubleshoot your thermostat and reversing valve to see what we can do to fix it. 

Other Problems

These are the two most common problems that we see with heat pumps not switching modes. But there is always the chance that something entirely different is wrong with the system. It’s always a good idea to have an expert come take a look when something is going wrong. Maybe your refrigerant charge is simply too low enough to cool air for your home, and you just think that the reversing valve is the problem. No matter what it is, our team can fix the problem quickly and correctly the first time.
