The decision to install an air source heat pump (ASHP) is one that many homeowners grapple with. A crucial factor to consider when making this choice is your local climate or location. This blog post will discuss how different climates affect the performance of an ASHP and help you determine if it's an ideal solution for your heating and cooling needs.

Understanding How an ASHP Works

An air source heat pump works by absorbing heat from the outside air and transferring it indoors. In colder months, ASHPs take outdoor heat—yes, there's heat in cold air—and move it inside. In the summer, the process reverses, and the pumps remove heat from your home and release it outdoors, thereby cooling the indoor space.

ASHPs in Mild Climates

In climates that have mild winters, where temperatures rarely drop below freezing, ASHPs can perform very well, providing both heating and cooling capabilities with high energy efficiency as compared to traditional HVAC systems. The heat pump has an easier task of extracting warmth from the external air, resulting in top-notch performance.

ASHPs in Cold Climates

Conversely, in extremely cold climates, where temperatures regularly fall below freezing, an ASHP may struggle to provide sufficient heat. However, advancements in technology have produced 'cold climate' ASHPs designed to perform well in lower temperatures. These can function effectively even when temperatures dip well below freezing. Still, it's essential to ensure you choose a model suited to your specific climate needs, and often a secondary heat source like a furnace might be needed for especially chilly days.

Considerations for Humid Climates

Air source heat pumps can also effectively control humidity levels, more so than some traditional HVAC systems. Therefore, they can be a great choice in areas with high humidity levels, making indoor spaces more comfortable.

Consult with HVAC Professionals

Because location and climate variability are so key to an ASHP's effectiveness, it's crucial to seek professional advice when considering this heating and cooling solution. A local HVAC professional will have helpful insights regarding the most effective and efficient systems for your specific location.


Air source heat pumps can be a fantastic solution for many homes, providing both heating and cooling capabilities. However, their effectiveness is heavily influenced by your location and the corresponding climate. While they excel in mild climates, in colder conditions, you may need to consider a cold-climate ASHP or provide a backup heating solution. Furthermore, if controlling humidity is a concern, an ASHP could be a great option. Always consult with a HVAC professional to ensure that you're making the best choice for your heating and cooling needs.
