What to Expect When Installing Your Heat Pump


Installing a heat pump is an excellent step towards energy efficiency and consistent indoor comfort. However, the process may seem daunting, especially if you need to become more familiar with what to expect. This article breaks down the installation process, ensuring you\’re fully prepared when the big day arrives.

Understanding the Heat Pump Installation Process

Initial Consultation and Assessment:

The process begins with a professional visiting your home to assess your needs and determine the best type of heat pump for your space. This assessment will consider your home\’s layout, insulation, and heating system.

Choosing the Right Location:

Heat pumps must be placed where air can circulate freely. The external unit should be situated away from direct sunlight and water sources. In contrast, internal units should be placed in areas that promote efficient heating and cooling.

Preparing for your Heat Pump Installation

Clearing the Area:

Ensure that the area where the heat pump will be installed is clear of debris and accessible to the technicians.

Checking Electrical Systems:

Your existing electrical system may need an upgrade to handle the new heat pump, which will be determined during the initial assessment.


Installation typically takes a day, but it might extend depending on the complexity of your system and home layout.
