  • door types

  • total square footage

  • other factors to fulfill the homeowner’s comfort requirements.

In addition to the load calculation, the site’s readiness for outdoor units is also evaluated. The following steps are taken to ensure stability and protection for the new heat pump:

  1. The ground is leveled.

  2. A recommended composite pad is selected for the new heat pump to sit on.

  3. In regions like Ohio, it’s advisable to elevate the heat pump about 9 inches above the pad to safeguard it from snow accumulation, which can impact the functionality of the unit.

  4. This is a critical step as it averts potential freezing or air leaks that may hamper the heat pump’s performance.

Removing the Old System

The existing system needs to be safely dismantled before the new heat pump can be fitted. This step includes the following tasks:

  1. Turn off the power to the system to establish a safe working environment.

  2. Use a screwdriver to remove any screws or fasteners holding the system components in place.

  3. Use an adjustable wrench to disconnect any pipes or fittings.

  4. Use a hand truck to transport heavy components, such as the indoor evaporator coil, to a safe location.

  5. Use a vacuum pump to remove any refrigerant from the system.

  6. Use a nitrogen kit to purge the system of any remaining refrigerant or contaminants.

These specialized tools and steps are necessary for the safe and efficient removal of the indoor evaporator coil and other system components.

The removal process entails:

  1. Utilizing a recovery machine to capture and safely remove the refrigerant from the old system.

  2. Disengaging the electrical connections.

  3. Readying the system for removal.

These steps ensure that you can install heat pumps smoothly and safely, with new electrical connections put in place for your new heat pump.

Installing the New Heat Pump Components

With the safe removal of the old system and site preparation completed, it’s time to begin closing process of installing the new heat pump components. It’s important to ensure the outdoor unit is positioned at a higher elevation than the snow level to ensure efficient operation and minimize snow-related complications.

The indoor unit of an air conditioner typically includes a cased evaporator coil, which enables the system to switch between heating and cooling modes, providing cool air when needed. The refrigerant lines are connected using a process called brazing, which effectively joins the copper line set and service valves, ensuring a long-lasting and leak-free operation of cooling systems.

The installation process for a heat pump typically involves the following steps:

  1. The heat pump is connected to the home’s electrical system.

  2. The thermostat is configured to initiate the heating and cooling cycles of the pump.

  3. An outdoor sensor is installed, which signals the heat pump to transition between heating and cooling modes and activates a defrost mode in low temperatures.

One key difference to consider between air-source and ground-source heat pump installations is that ground-source pumps do not have a visible outdoor unit. Instead, ground loops are buried, unlike air source heat pumps that do have access to an outdoor unit.

Factors Affecting Installation Time

Comprehending the installation process is vital, but it’s equally significant to recognize that several factors can influence the length of a heat pump installation. These include weather conditions, modifications to the ductwork, and electrical upgrades.
