The Difference Between a Standard Heat Pump and a Split System Heat Pump

Everybody enjoys going to a cool home during the summertime heat. Unfortunately, not everybody can install central air-conditioning, and numerous people use window units. However, some places in the home aren't fit for window ACs. If you're looking for an unobtrusive way to bring more cool air into the home, our standard heat pump or a split system heat pump might be the ideal solution for your temperature-regulating issues. A heat pump is part of a central cooling and heating system that uses the external air to heat a home during winter and cool the home during summer. Here's what you need to know.

Standard Heat Pump Function

A heat pump is a mechanical system that can be reversed to cool or heat a controlled space. When you invest in our heat pumps for sale, installation usually comprises two parts: an indoor unit, the air handler, and an outdoor unit comparable to a central AC. A heat pump is like a heat transporter that constantly moves warm air from one place to another. Heat pumps work by transferring a refrigerant through a cycle of condensation and evaporation. This cycle is completely reversible allowing a heat pump to offer year-round climate control for a home by dehumidifying and cooling during summer and heating during winter. One benefit you can expect when you buy heat pump system is that it moves heat instead of generating it, enabling energy efficiency. Moreover, it's electricity-powered, so you will save a considerable amount on fuel consumption.

Split System Heat Pump Function

On the other hand, a split system heat pump comprises outdoor and indoor components that function together. On your home's exterior is the condenser or compressor, which sustains the optimal rate of the refrigerant's flow while increasing the refrigerant gas pressure through compression.

On the home's interior is the air handler, which distributes and cycles the air. A protected conduit joins the two parts. Unlike most traditional heat pumps, split systems are usually ductless. Additionally, numerous models enable the attachment of several indoor air handlers to a single outdoor condenser. Individual thermostats can program each of the air handlers indoors, thereby maintaining individual rooms at their specific temperature. You'll discover that the ability to control particular rooms saves energy and money. The split system redefines efficiency by eliminating the necessary duct system in traditional HVAC systems and packaged heat pumps.

Heat Pump Components


Since the heat pump functions in cold weather, there's a likelihood that the compressor may take in some liquid. Consequently, these appliances have accumulators, which gather liquid refrigerant and enable the machine to boil it into vapor before entering the compressor. This prevents liquid slugging, which could damage an AC compressor or heat pump beyond repair.


This component regulates the heating mode via a 4-way or reversing valve. The thermostat reverses the process of refrigeration when setting to the heating mode. When you require a new thermostat, it's imperative to recognize whether you have a heat pump or an air conditioner as there is a distinction between an air conditioner thermostat and a heat pump thermostat. While some manufacturers produce all-purpose thermostats, they aren't the same. We advise clients to ensure they have the appropriate thermostat, particularly for heat pumps.

Split System Components


When a split system is functioning, its thermostat will continually detect the existing air temperature. If its reading reveals an air temperature that's warmer than preferred, the system will turn on automatically. The thermostat in a split system is usually on the interior unit.


Once the thermostat signals the split system that it's time to begin cooling space, the compressor begins circulating refrigerant-a liquid substance that converts into gas as it cools. When refrigerant moves through the coils in the unit, it naturally starts cooling down the adjacent air. Low refrigerant can result in a general loss of efficiency and performance.

Evaporator Fan

As the refrigerant circulates through the system, an evaporator begins gathering warm air from the room. The warm air moves through a chilling chamber once the fan captures it. The air then recalculates indoors after being chilled, leading to lower temperatures. The compact nature of the compressor and evaporator systems permits the split system to be an effective addition to any HVAC. Whether you find that you're spending a considerable amount on air conditioning repair or you just feel it's time for the replacement of your AC unit, our company has professionals who will guide you on selecting the appropriate unit for your home.
