How to Install and Maintain Heat Pumps

A heat pump is a type of air conditioner that uses an indoor coil to distribute heated air throughout a home. The air passes over the coil and is distributed through ductwork. Typically, a single outdoor unit serves multiple indoor units. If you are looking to install a heat pump in your home, there are a few different types available.

Heating seasonal performance factor (HSPF)

The heating seasonal performance factor (HSPF) is a measure of the energy efficiency of a heat pump. It is calculated by dividing the heat pump’s heating output by the total energy it uses. The HSPF rating is measured in kilowatt-hours. One kWh is equal to 1,000 watt-hours. This metric is used to compare the efficiency of different heat pumps.

There are different methods of determining the HSPF. For example, some heat pumps use a supplementary electric resistance heater (SERH) to increase output during peak demand. Others use a ground loop and heating circulation pumps. Manufacturers also have a choice of testing for the PLF, but this is optional. The default PLF value reduces heat pumps’ performance by up to 25%. ThisĀ furnace repair test is conducted by the manufacturers themselves, but the data is not publicly available.

Coefficient of performance (COP)

Coefficient of performance (COP) is an important measure of the efficiency of heat pumps. This measure measures the ratio of the cooling output of the evaporator to the electrical power required to run the device. A higher COP means more power consumed and higher running costs. The Coefficient of performance (COP) of a heat pump can be improved by reducing the temperature differences between rooms and enhancing insulation. It can also be improved by using a ground-source heat pump system.

The best heat pumps have a COP of 4.5 or higher. However, heat pumps with lower COPs have room for improvement. COP figures are often much lower than those of real air conditioners. In reality, heat pumps use cold ambient air and heat it up to a comfortable room temperature. This does not violate conservation principles.


There are several different types of heat pumps. One of the most common types of heat pumps is ductless, which is installed on walls throughout the home. These systems can save you money on your heating bill as they use less energy per kWh. These are also more environmentally friendly than furnaces because they don’t burn fossil fuels.

Absorption heat pumps use another heat source for their power, such as geothermal or solar water. They are most often used in industrial settings, but are increasingly being used in larger homes and buildings. These pumps also offer the added benefit of providing heating during the summer and cooling during the winter.


Before you install a heat pump, you must prepare the area where it is to be installed. This includes removing the pad and leveling the ground. A good HVAC company will use a gravel base to make the area flat, then build up the area where the new heat pump will go. If you want to avoid additional costs, you can install a composite pad that is designed to be outside and will last the life of the heat pump.

Installing a heat pump is fairly simple if you follow the steps described below. First, you must make sure the system is located where it will be most effective. This will allow it to provide even heat and cool air in a home. Once the system is in place, it is important to ensure that it is working properly. A heat pump has two main parts: the indoor unit and the outdoor unit. Each unit has an electric component and piping that must connect. Once the units are in place, the contractor must make sure the units are connected to the home’s electrical system.


In order to get the most out of your heat pump, you must know how to maintain it. It is not a do-it-yourself project. In fact, improper maintenance can cause more damage than good. You should contact a technician to handle your heat pump maintenance needs. Here are some steps to take to ensure optimum performance.

Schedule regular maintenance sessions. Ensure that your heat pump gets pre-season tune-ups in the spring and fall. These tune-ups ensure that your heat pump is working at optimal efficiency and performance.
