\"logo-of-sun-and-snowflake\"When it comes to the weather in Florida, it\u2019s fairly predictable\u2014it\u2019s always hot, right?<\/p>\n

Well, if you\u2019ve lived in our area for even just a year or two, you know that\u2019s not always the case. Sure, we don\u2019t get snow <\/em>in the fall and winter like other states along the east coast. But when temperatures drop, the contrast is enough to make us very thankful for our heating systems.<\/p>\n

One of the most common types of heaters used within our climate is the heat pump system\u2014because we do have mild winters but very hot summers, the refrigerant process of a heat pump is the perfect year-round, 2-in-1 HVAC system.<\/p>\n

If you already have one in your home, you\u2019re using one of the most efficient heaters you can find! Though, if you\u2019re reading this particular blog post, it likely means you found it won\u2019t switch to heating mode. Why is this happening?<\/p>\n

Refrigerant Flow<\/h2>\n

To answer this question, we first need to explain how refrigerant works within your heat pump system. When in heating mode, the refrigerant circulates through the inside and outside components of the system to absorb heat from the outdoor air and bring it in. When it\u2019s switched to cooling mode, a reversing valve<\/em> activates to help that refrigerant flow in the opposite direction.<\/p>\n

There are components called check valves <\/em>that help the refrigerant avoid some parts it would otherwise pass through in the opposite mode. In order to switch from cooling to heating mode this winter, your heat pump relies on these valves in addition to another part called a sliding cylinder <\/em>to do the job. Read on as we describe these components, and what can go wrong with them, in more detail.<\/p>\n
