Our DIY Heat Pump Install – Free Heating and Cooling for Life?


In this article, we will delve into the topic of installing a heat pump as a DIY project, exploring the potential benefits and drawbacks. We will also discuss the significance of heat pumps in revolutionizing the way we heat and cool our homes. This informative piece aims to provide a comprehensive guide for those considering a DIY heat pump installation.

The Quest for Optimization

Mr. Money Mustache, known to many as the early retirement financial guru, has a different perspective on life. He sees himself as a general Life Engineer, someone who strives to optimize various aspects of life for maximum enjoyment and efficiency. This includes finding ways to make the most out of money, time, health, and happiness. And when it comes to optimizing one’s living space, the choice of a home can have a significant impact on both financial and emotional well-being.

The Exciting Potential of Heat Pumps

Heat pumps have emerged as a game-changing technology in the housing industry. Similar to how the iPhone transformed the tech industry or how electric cars are revolutionizing transportation, heat pumps have the potential to redefine how we heat and cool our homes. The appeal of heat pumps lies in their numerous advantages:

  1. They are highly effective at both heating and cooling any building, all in one compact machine.
  2. Heat pumps are easy to install and more cost-effective to operate. They also enable more affordable construction methods by reducing the need for excessive materials and labor.
  3. By eliminating the reliance on burning oil or gas for heat, heat pumps contribute to reducing pollution, especially when coupled with clean energy sources.
  4. Advancements in technology have made heat pumps suitable for use in a wide range of climates, including areas with harsh winters.

The Magic Behind Heat Pump Operation

Contrary to popular belief, heat pumps do not generate heat directly like traditional electric heaters. Instead, they excel at transferring heat from one place to another. In the summer, heat pumps extract heat from the interior and release it outside. Conversely, during the winter, they draw heat from the outdoor air and transfer it indoors. This process may seem like magic, but it is simply a result of physics. Even in cold outdoor temperatures, there is still an ample amount of heat available to be harnessed.

Benefits of DIY Heat Pump Installation

Undertaking a DIY heat pump installation can be a rewarding endeavor if you possess the necessary skills and choose a DIY-friendly heat pump kit. While it may not be as simple as assembling IKEA furniture, installing a heat pump is considerably easier than installing a gas furnace or a metal roof.

The primary advantage of a DIY installation is the substantial cost savings. Professional installation of a heat pump can cost thousands of dollars, whereas a DIY approach can save you a significant amount of money. In fact, a basic installation can save you around $6,000 in exchange for approximately 16 hours of work. This translates to a commendable hourly rate of $375.

Step-by-Step Guide to DIY Heat Pump Installation

Step One: Selecting the Right Heat Pump

When choosing a heat pump, two crucial factors to consider are the physical size and heat output. Ensure that the dimensions of the indoor portion of the system align with your existing furnace or have a plan to adapt the new unit to fit within your ductwork. As for heat output, assess the capacity of your old furnace to determine the suitable heat pump output.

Step Two: Removing the Old Furnace

Before starting any work, prioritize safety by turning off the gas and electric supply to your furnace. Once the system is safely disabled, carefully remove the old furnace, preserving the ductwork. You can sell or give away the old furnace or dispose of it responsibly.

Step Three: Customizing the Ductwork

Adapting the ductwork may be necessary, depending on the size and configuration of the new heat pump. Connecting the return ductwork to the bottom of the heat pump and the supply ducts to the top is straightforward if you are lucky and the sizes match. However, you may need to make modifications if the sizes differ.

Step Four: Installing the Heat Pump

Once the ductwork is ready, the installation process becomes relatively easy. Secure the sheet metal boxes to the bottom and top of the heat pump, ensuring a tight seal. At this point, the project nears completion, and enthusiasm builds.

Step Five: Positioning the Outdoor Unit

The outdoor unit should be placed in a location that is both out of the way and in close proximity to the indoor air handler. With the help of a high-quality dolly and ratcheting straps, as well as an extra pair of hands, move the heavy outdoor unit into its designated spot. Connect the indoor and outdoor units with a lineset, making sure the length is appropriate for optimal performance.

Step Six: Running the Lineset

The lineset consists of flexible copper tubes wrapped in insulation. Carefully unroll and straighten the lineset, feeding it through a drilled hole in the side of your house. This step may require extra effort, particularly when drilling through thick walls. Once in position, follow the manufacturer’s instructions to connect the lineset to the condenser and air handler.

Step Seven: Wiring the Electrical Components

Electrical wiring requirements may vary depending on the system. Consult a professional electrician to ensure the proper installation of a 40 amp / 240 volt circuit for the outdoor unit, a 20 amp / 240 volt circuit for the main unit, and the necessary thermostat wiring. Take advantage of this opportunity to upgrade to a smart wifi thermostat for added convenience and energy efficiency.

The Moment of Truth: Firing Up the System

After completing all the necessary steps, it’s time to flip the breakers and power on the system. Don’t be alarmed if there is a brief delay before the heat pump starts operating. Once it kicks in, revel in the joy of cool air flowing through your home during hot summer days or the comfortable warmth it provides during colder seasons.

Enjoy the Benefits of DIY Heat Pump Installation

Throughout the summer, the heat pump will prove its worth as it effortlessly keeps your home cool and comfortable. As winter approaches, you can look forward to the efficiency and reliability of the heat pump in providing ample heat. The installation process may require some effort, but the rewards are well worth it.

Conclusion: Embracing the Future with Heat Pumps

By implementing a DIY heat pump installation, you can free yourself from the burden of high energy bills and reduce your environmental footprint. The initial investment of time and effort can result in a lifetime of cost-effective, eco-friendly heating and cooling. Heat pumps are the way of the future, offering a win-win solution for both your comfort and the planet.
