Most homeowners know that heat pumps and air conditioners use refrigerants as part of their cooling process, but many wonder: does a heat pump still use Freon in the winter? The answer is yes. Even during the cold months, your heat pump relies on Freon or another type of liquid refrigerant to provide heating by effectively transferring and reusing waste heat.
In this blog, Doc Dancer Plumbing, Heating, AC & Generators, will explain how heat pump systems operate in the winter, the role refrigerants play, and how to keep your system running efficiently throughout Indiana’s colder months.
What Is Freon?
Freon, also known as R-22 or HCFC-22, is a refrigerant that was widely used in older heat pumps, air conditioners, and refrigerators. It works by facilitating heat exchange, transferring heat energy from one area to another, enabling both cooling and heating functions.
However, Freon has been phased out in the U.S. due to its harmful effects on the ozone layer, as regulated by the Montreal Protocol. Since 2010, new heat pumps have used more environmentally friendly refrigerants like R-410A (commonly known as Puron) or other modern alternatives. Although a limited supply of Freon is still available for servicing older systems, upgrading to a modern, energy-efficient heating system is recommended for long-term energy savings and sustainability.
How Does a Heat Pump Work in Winter?
Heat pumps work by transferring heat energy between two areas rather than needing to generate heat like traditional systems. In winter, air source heat pumps extract heat energy from the outdoor air, even when temperatures drop, and transfer it indoors to warm your home.
In contrast, geothermal heat pumps (also known as ground source heat pumps) draw heat energy from the stable underground temperatures. A network of buried pipes, called a ground loop, circulates a liquid that absorbs heat from the ground and delivers it to the heat pump. This makes geothermal systems highly efficient, especially in colder climates where outdoor air may not provide as much energy for air source heat pumps.
By utilizing these methods, heat pump systems deliver reliable and energy-efficient heating during the winter and effective cooling in the summer.
The Role of Refrigerants in Heat Pumps
Refrigerants like Freon or Puron are essential to the refrigeration cycle, enabling heat exchange between the indoor and outdoor units of your heat pump system. The heat exchanger, a key component of the system, facilitates this process by transferring heat energy efficiently.
Here’s how the process works:
- Heat Absorption: The refrigerant passes through the outdoor coil, where it absorbs heat from the outdoor air or the ground in the case of geothermal heat pumps. This absorption causes the refrigerant to reach its boiling point, converting it into a low-temperature vapor.
- Compression: The compressor pumps the refrigerant, increasing its pressure and temperature, turning it into a hot gas.
- Heat Release Indoors: The hot gas moves to the indoor coil, where it releases heat energy to the air circulating inside your home. This heat produced is then circulated throughout your home by the central heating system.
- Reverting to Liquid Form: As the refrigerant releases heat, it cools and condenses back into a liquid, ready to repeat the cycle.
Why This Process Is So Efficient
The refrigeration cycle enables heat pumps to efficiently move heat rather than generate heat, which significantly reduces energy consumption. This process results in substantial energy savings and makes heat pumps an outstanding choice for residential heating.
Whether you use an air source heat pump or a geothermal system, these technologies provide a sustainable way to keep your home warm with outstanding energy efficiency. With the ability to deliver consistent warmth through their heating mode, heat pumps are a versatile and eco-friendly option for modern homes.
My Heat Pump Is Leaking Refrigerant, What Should I Do?
If your heat pump system is leaking refrigerant, it’s not something to ignore. Refrigerant leaks disrupt the refrigeration cycle, making it harder for your heat pump to provide heating or cooling effectively. Unlike oil in a car, refrigerant doesn’t get “used up” over time—it flows continuously through your system. A leak indicates a problem that needs immediate attention.
Signs of a refrigerant leak include:
- A noticeable drop in your heat pump’s ability to maintain the desired temperature.
- Increased energy bills due to reduced efficiency.
- Strange noises or frost buildup on the outdoor unit.
Only certified heating and cooling system professionals should handle refrigerants. At Doc Dancer, our skilled technicians will inspect your system, repair any leaks, and restore refrigerant levels to ensure optimal operation. Addressing leaks promptly prevents further damage and ensures your home stays comfortable all year.
