Unlike a traditional furnace that generates heat by burning fuel or using electric resistance, a heat pump moves heat from one place to another. This process allows it to provide both heating and cooling with the same equipment.<\/p>\r\n<p>Understanding how a heat pump works can help you decide whether one is right for your home, recognize when something is not operating as expected, and know when to call an HVAC professional. Galmiche &#038; Sons helps homeowners in St. Louis and surrounding communities explore heat pump options and keep their heating and cooling systems operating as intended.<\/p>\r\n<p>To learn more about heat pumps, check out our <a href=\"https:\/\/www.galmicheandsons.com\/heat-pump-buyers-guide.html\">heat pump buyers guide<\/a> or contact us today.<\/p>\r\n<h2><span class=\"ez-toc-section\" id=\"How_Does_a_Heat_Pump_Work\"><\/span>How Does a Heat Pump Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>A heat pump uses refrigerant and a cycle of compression, heat transfer, and expansion to move heat between your home and the outdoors. During summer, it removes heat from inside your house and releases it outside. During winter, it collects available heat from outdoor air and transfers that heat indoors.<\/p>\r\n<p>The important distinction is that a heat pump <strong>moves heat rather than simply generating it<\/strong>. Even when outdoor air feels cold, it contains thermal energy that a properly designed heat pump can extract. How much heat the system can move efficiently depends on the equipment and outdoor conditions.<\/p>\r\n<p>Because one system can provide both heating and cooling, a heat pump can be a practical option for homeowners who want year-round comfort from a single piece of equipment.<\/p>\r\n<h2><span class=\"ez-toc-section\" id=\"How_a_Heat_Pump_Cools_Your_Home_in_Summer\"><\/span>How a Heat Pump Cools Your Home in Summer<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>In cooling mode, a heat pump works much like a conventional air conditioner. It removes heat from indoor air and transfers it to the outdoors.<\/p>\r\n<p>Here is how the process works:<\/p>\r\n<ul>\r\n<li><strong>Warm indoor air passes over the indoor coil.<\/strong> A fan moves air across the coil, where refrigerant absorbs heat from the air.<\/li>\r\n<li><strong>The refrigerant carries the heat outside.<\/strong> As it absorbs heat, the refrigerant changes state and circulates through the system.<\/li>\r\n<li><strong>The compressor raises the refrigerant&#8217;s pressure.<\/strong> This increases its temperature, allowing it to release heat at the outdoor coil.<\/li>\r\n<li><strong>The outdoor coil releases heat.<\/strong> The outdoor fan moves air across the coil, helping transfer heat from the refrigerant into the outdoor air.<\/li>\r\n<li><strong>The refrigerant pressure drops.<\/strong> An expansion device lowers the refrigerant pressure before it returns to the indoor coil, allowing the cycle to repeat.<\/li>\r\n<\/ul>\r\n<p>As the heat pump removes heat from your home, it can also remove moisture from indoor air under suitable operating conditions. This helps support indoor comfort during humid St. Louis summers.<\/p>\r\n<p>If your heat pump runs but your home stays warm, airflow is weak, or cooling performance changes noticeably, the cause could range from a dirty filter to a refrigerant or component problem. Checking the thermostat and filter is a reasonable first step, but persistent issues should be evaluated by an HVAC professional.<\/p>\r\n<p>Learn more about <a href=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/common-heat-pump-problems-and-solutions\/\">common heat pump problems<\/a>.<\/p>\r\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/2026\/10\/how-does-a-heat-pump-work-1-300x201.jpg\" alt=\"How Does a Heat Pump Work?\" width=\"300\" height=\"201\" class=\"alignright size-medium wp-image-20811\" srcset=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/2026\/10\/how-does-a-heat-pump-work-1-300x201.jpg 300w, https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/2026\/10\/how-does-a-heat-pump-work-1.jpg 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><h2><span class=\"ez-toc-section\" id=\"How_a_Heat_Pump_Heats_Your_Home_in_Winter\"><\/span>How a Heat Pump Heats Your Home in Winter<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>When the thermostat calls for heat, a heat pump reverses the direction of heat transfer. Instead of removing heat from your home, it extracts heat from the outdoor air and delivers it indoors.<\/p>\r\n<p>The heating process follows the same basic refrigeration cycle, but the indoor and outdoor coils perform different roles:<\/p>\r\n<ul>\r\n<li><strong>The outdoor coil absorbs heat:<\/strong> Refrigerant collects thermal energy from the outdoor air.<\/li>\r\n<li><strong>The compressor increases pressure and temperature:<\/strong> This allows the refrigerant to deliver heat at a higher temperature.<\/li>\r\n<li><strong>The indoor coil releases heat:<\/strong> Indoor air passes over the coil and picks up warmth before circulating through your home.<\/li>\r\n<li><strong>The refrigerant expands and returns outdoors:<\/strong> Its pressure drops, preparing it to absorb more heat and repeat the cycle.<\/li>\r\n<\/ul>\r\n<p>A heat pump can extract usable heat even when outdoor temperatures are below freezing. However, its heating capacity and efficiency generally change as temperatures fall, and performance varies by model.<\/p>\r\n<p>Some systems include supplemental electric heating, while dual-fuel systems can use a furnace when additional heat is needed or when the system&#8217;s controls determine that another heating source is appropriate.<\/p>\r\n<p>For more information about equipment designed for winter conditions, see our guide to Cold-Weather Heat Pump Performance.<\/p>\r\n<h2><span class=\"ez-toc-section\" id=\"What_Does_the_Reversing_Valve_Do\"><\/span>What Does the Reversing Valve Do?<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>The reversing valve is one of the key components that allows a heat pump to provide both heating and cooling. It changes the direction in which refrigerant flows through the system, switching the roles of the indoor and outdoor coils.<\/p>\r\n<p>In cooling mode, the indoor coil absorbs heat and the outdoor coil releases it. In heating mode, the outdoor coil absorbs heat and the indoor coil releases it into your home.<\/p>\r\n<p>The thermostat and system controls signal the equipment to operate in the appropriate mode. The reversing valve then directs refrigerant flow to support heating or cooling.<\/p>\r\n<p>If a heat pump consistently delivers air that does not match the selected mode, a control or reversing valve issue may be one possible explanation. Other problems can cause similar symptoms, so accurate diagnosis is important before replacing components.<\/p>\r\n<p>Learn more about what to do if your <a href=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/heat-pump-not-heating-or-cooling\/\">heat pump is not heating or cooling properly<\/a>.<\/p>\r\n<h2><span class=\"ez-toc-section\" id=\"The_Main_Components_of_a_Heat_Pump\"><\/span>The Main Components of a Heat Pump<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>Knowing the basic parts of a heat pump makes it easier to understand how the system operates and why professional service can be valuable.<\/p>\r\n<ul>\r\n<li><strong>Compressor<\/strong>: The compressor circulates refrigerant and raises its pressure, helping it reach the temperature needed to transfer heat effectively.<\/li>\r\n<li><strong>Indoor and Outdoor Coils<\/strong>: The coils transfer heat between refrigerant and air. Depending on whether the system is heating or cooling, each coil absorbs or releases heat.<\/li>\r\n<li><strong>Refrigerant<\/strong>: Refrigerant is the working fluid that carries heat through the system as its pressure and physical state change. Refrigerant circuits should only be serviced by qualified professionals with appropriate equipment and training.<\/li>\r\n<li><strong>Expansion Device<\/strong>: This component reduces refrigerant pressure before it enters the coil where heat absorption begins. It helps the system maintain the conditions needed for the heat transfer cycle.<\/li>\r\n<li><strong>Fans and Air Handler<\/strong>: Fans move air across the coils. In a ducted system, the indoor air handler circulates conditioned air through the home&#8217;s ductwork. Ductless systems use indoor units to deliver conditioned air directly to specific rooms or zones.<\/li>\r\n<li><strong>Thermostat and Controls<\/strong>: The thermostat measures indoor temperature and signals the system when heating or cooling is needed. Additional controls coordinate system operation and may manage features such as defrost cycles or supplemental heating.<\/li>\r\n<\/ul>\r\n<p>Together, these components allow a heat pump to transfer heat and maintain comfortable indoor temperatures.<\/p>\r\n<h2><span class=\"ez-toc-section\" id=\"Why_Heat_Pumps_Can_Be_Energy_Efficient\"><\/span>Why Heat Pumps Can Be Energy Efficient<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>A heat pump can provide more heating energy than the electrical energy it consumes because it transfers heat from the environment rather than relying entirely on electricity to generate heat. The amount of energy used depends on outdoor conditions, system design, equipment efficiency, and how the home operates.<\/p>\r\n<p>Efficiency is not the only factor to consider when choosing a system. Proper sizing, installation, airflow, insulation, thermostat settings, and routine maintenance all influence performance.<\/p>\r\n<p>If you are comparing models, our guide to Heat Pump Efficiency Ratings can help you understand the ratings used to compare equipment.
