3 Causes of Heat Pump Failure This Spring

When heat pumps encounter problems this spring, it usually stems from one major cause: a lack of cool air when you turn them on. Heat pumps have likely been in warming mode for more of the winter, but spring has arrived in Normangee, TX, and that means you ‘’ll be switching it over to cooling mode before long, if you haven’t done so already.  You may be in for a bit of a shock if you do so only to find that there’s no cool air coming out of your system. There’s a number of reasons why, and the issue may have lingered for weeks or even months since you spent the winter with your system in heating mode. Here are three potential causes to look out for.

1.      Low Refrigerant

Refrigerant moves in an endless cycle through the heat pump and it requires a set amount in the system in order to cool the air properly (and heat it in the winter, for that matter). Leaks aren’t supposed to spring up, but they do sometimes, and when they do, that delicate balance is thrown off and the cool air won’t be generated.

2.      Broken Reversing Valve

Heat pumps are designed to function as both heaters and air conditioners by reversing the flow of refrigerant depending on the setting. A reversing valve allows that to happen. If the valve breaks for malfunctions, you won’t be able to shift modes, and since your heat pump has likely been heating for the last few months, there won’t be any cool air.

3.      Faulty Thermostat

A bad thermostat can wreak havoc with a heat pump, causing it to run when it shouldn’t or blow hot air when cool air is called for. Always check the thermostat before calling in a repair service to see that it’s set correctly. If it is, then the issue may lie there instead of in the system itself.
