Frequently Asked Questions about Heat Pump Installation

How do heat pumps work in cold climates?

While heat pumps are most efficient in moderate climates, advancements in technology have made them a viable option even in colder regions. Modern heat pumps can operate in temperatures as low as -13°F (-25°C), thanks to advancements in refrigerant technology and system design. However, in extremely cold climates, a supplemental heat source, such as an electric resistance heater or a gas furnace, may be necessary to maintain comfortable indoor temperatures. Dual-fuel or hybrid heat pump systems, combining a heat pump with a furnace, offer the optimal balance of efficiency and comfort in cold climates.

What is a variable-speed heat pump?

A variable-speed heat pump has a variable-speed compressor based on the heating or cooling needs of your home or business. Unlike single-stage heat pumps, which operate at either full capacity or off, variable-speed heat pumps can modulate their output to precisely match the required heating or cooling load.. This results in more consistent temperatures, quieter operation, and better energy efficiency compared to single-stage systems. This reduces strain on components, thereby maximizing the lifespan of your system.

What is the difference between an air source heat pump and a geothermal heat pump?

The key difference between air source and geothermal heat pumps lies in where they get their heat:
Air source heat pumps extract heat from the outside air. They are less expensive to install than geothermal heat pumps, but their efficiency can be affected by extreme outdoor temperatures.
Geothermal heat pumps use the stable temperature of the earth as their heat source. They are more expensive to install due to the ground loop requirements, but their efficiency remains consistent even in extreme weather.

What is a geothermal heat pump?

A geothermal heat pump uses the earth's natural temperature to provide heating and cooling. It circulates fluid through underground pipes (a ground loop), absorbing heat from the earth in winter and transferring it into the building.. In the summer, the process reverses, and the system transfers heat from the building to the ground. While geothermal heat pumps have a higher initial cost than traditional HVAC systems due to the ground loop installation, their operating costs are significantly lower, resulting in long-term savings and a smaller carbon footprint.
