Heat pumps cut heating costs by $500 per year, on average, improving comfort while reducing carbon footprint.
Examples
1Space Heating/Cooling
The most popular application, providing comfortable indoor temperatures by transferring heat in or out as needed.
2Water Heating
Heat pumps can efficiently heat water for domestic use, like bathing and dishwashing.
3Dryers
Heat pump dryers offer greater energy efficiency than conventional models, drying clothes by reheating internal air instead of drawing in large amounts of cold air.
4Swimming Pools
Heat pumps can maintain a pleasant water temperature, using less energy than traditional pool heaters.
5Integrated Systems
Some homes use heat pumps for combined space heating, cooling, and water heating, maximizing efficiency.
Pros
- Energy Efficiency: Heat pumps use less energy compared to traditional HVAC systems, as they transfer heat instead of producing it, potentially leading to substantial savings on utility bills.
- Lower Emissions: By using less energy, heat pumps reduce your home’s carbon footprint, making them a more sustainable choice for combating climate change compared to fossil fuel-based systems.
- Versatility: Heat pumps provide both heating and cooling, offering year-round comfort from a single system, unlike many other HVAC solutions.
Cons
- Upfront Costs: Heat pumps can be more expensive to install than conventional systems. However, this can be offset by long-term energy savings and various incentives or rebates.
- Performance in Extreme Cold: While technology is improving, some heat pumps may struggle to heat efficiently in extreme cold, although supplementing with a secondary heat source can mitigate this.
- Installation Complexity : Proper installation is critical for optimal operation and requires a skilled technician, adding to the upfront cost.

Do It Yourself
- Educate Yourself: Start your search with trusted books & websites such as those found in our resources.
- Right Tools: Ensure you have all necessary tools and safety equipment. Heat pump installation requires specialized tools for tasks like refrigerant handling.
- Understand Your System: Different heat pumps (air-to-air, geothermal, etc.) have different installation procedures. Be sure you’re familiar with your specific model.
- Follow Local Codes: Check local building and environmental codes to ensure your project is compliant, and obtain necessary permits.
- Seek Professional Help if Needed: Heat pump installation is complex. If you’re uncertain at any stage, don’t hesitate to call a professional. Improper installation can lead to higher operational costs and decreased lifespan of the unit.
Tips for Renters
Looking for a Rental:
1Ask Upfront
In your initial inquiry about a property, ask about the type of HVAC system installed.
2Prioritize Energy Efficiency
Rentals with heat pumps will likely have lower utility bills and provide more consistent comfort.
3Check the System
If you tour the property, try to see the HVAC unit. Heat pumps often have labels or brand names that indicate their type.
Convincing a Landlord:
1Highlight the Savings
Emphasize the potential for lower utility costs and maintenance expenses with heat pumps.
2Discuss Incentives
Some areas offer rebates or tax credits for installing heat pumps, reducing upfront costs.
3Promote Long-Term Value
Installing a heat pump can increase property value and attract future energy-conscious renters.
Tips for Designers & Builders
For the Design Team:
1Size Accurately
Correct sizing of the heat pump system is essential for optimal performance and efficiency. Oversized or undersized systems can lead to increased energy usage and decreased comfort. Use the Manual J calculation method from the Air Conditioning Contractors of America to calculate the heating and cooling loads.
2Optimize Building Envelope
An energy-efficient building envelope can significantly enhance the performance of the heat pump system. This includes designing for superior insulation, air sealing, and window selection.
3Plan for Integration
The integration of the heat pump system with other systems, like ventilation and hot water, should be planned from the beginning. This can maximize overall system efficiency and provide enhanced comfort.
For the Builder:
1Ensure Proper Installation
Incorrect installation can lead to inefficient system performance and reduced lifespan of the unit. Follow manufacturer guidelines strictly and ensure the team is trained in heat pump installation.
2Plan for Future Maintenance
Make sure all components of the heat pump system are easily accessible for future maintenance. This can help ensure the system continues to operate efficiently for many years.
3Test the System
Before completing the project, thoroughly test the heat pump system to ensure it’s functioning as expected. Measure airflow, check refrigerant charge, and make sure all controls are working properly. This can help catch any issues early and ensure the system is ready for efficient operation.
