HEAT PUMP FAQ’s


As a multifamily building owner, you may have heard about heat pumps as an efficient and cost-effective way to heat and cool your property. However, you may also have some questions and concerns about their performance and reliability. In this article, we will answer some of the frequently asked questions about heat pumps, to help you make an informed decision about whether they are right for your building.

  • A heat pump is an HVAC system that uses refrigerant to transfer heat from one place to another. In the winter, it extracts heat from the outdoor air or ground and moves it indoors to heat your building. In the summer, it reverses this process to cool your building by moving heat outdoors. Heat pumps are more energy-efficient than traditional heating and cooling systems for a number of reasons, the most important one is that they don't generate heat or cool air; they move it from one place to another which makes them the ideal substitute for high carbon-generating types of equipment.

  • A hybrid heating system combines a heat pump with a traditional furnace or boiler. The heat pump is used for heating and cooling when outdoor temperatures are mild to severe, but the furnace or boiler takes over when the temperature drops below a certain point. This allows you to take advantage of the efficiency of a heat pump without sacrificing comfort in cold weather.

  • No, heat pumps do not increase humidity. In fact, they can help to reduce humidity in your building by removing moisture from the air during the cooling process. This can help to prevent mold growth and improve indoor air quality.

  • Wood fire heaters produce large amounts of smoke and particulate matter emissions that can trigger asthma. The same is the case with gas heaters which can release chemicals such as nitrogen dioxide which can be a trigger for asthma. Heat pumps are an amazing alternative for your tenants with allergies and asthma.

  • A well-maintained heat pump can last for 15 years or more. However, the lifespan of a heat pump depends on several factors, such as the quality of the equipment, the frequency of maintenance, and usage patterns. It's important to have your heat pump serviced regularly to ensure that it is operating at peak efficiency and to catch any potential issues before they become major problems.

  • The amount of electricity a heat pump uses depends on several factors, such as the size of the unit, the climate, and the temperature settings. However, heat pumps are generally more energy-efficient than traditional heating and cooling systems, which can result in lower utility bills over time. According to the U.S. Department of Energy, a well-designed and properly installed heat pump can save up to 50% on energy costs compared to traditional heating and cooling systems.

    The amount of electricity a heat pump uses depends on the size of the unit, the climate, and how often it runs. However, because heat pumps are more energy-efficient than traditional heating and cooling systems, they can save homeowners up to 30% on their energy bills.

  • A heat pump should run for at least 10-15 minutes at a time to be effective. Running the unit for shorter periods can reduce efficiency and increase wear and tear on the equipment. However, the exact amount of time a heat pump should run depends on several factors, such as the outdoor temperature, the size of the unit, and the temperature settings.

    In extremely cold or hot weather, the heat pump may run longer to keep up with demand. If your heat pump is running constantly, it may be a sign of an issue and should be inspected by a professional.

  • Heat pumps are quieter than traditional heating and cooling systems, but they can still produce some sound. The amount of noise a heat pump makes depends on several factors, such as the location of the unit, the size of the unit, and the type of compressor. However, many newer models are designed to be very quiet, with sound ratings as low as 56 decibels.

    Heat pumps are typically quieter than traditional HVAC systems because they don't rely on combustible fuel sources. However, some units may make noise when the compressor turns on or off. If you notice unusual noises coming from your heat pump, it may be a sign of a problem and should be inspected by a professional.

  • It's important to clean or replace the air filter in your heat pump regularly to ensure that it is operating at peak efficiency and to prevent dust and debris from accumulating in the system. To clean the filter, turn off the unit and remove the filter from the air handler. Clean it with a vacuum cleaner or wash it with soap and water, then let it dry and put it back in place. For specific cleaning guidelines, please follow the filter cleaning instructions that came with your heat pump.

    Cleaning the filter on your heat pump is an essential maintenance task that can help extend the life of your unit and improve its performance. If the filter is damaged, replace it with a new one.

  • Yes, heat pumps can work in the winter, even in cold climates. Technology has advanced in recent years to accommodate much lower temperatures. Many units now offer electric resistance heat strips that work in conjunction with your heat pump to ensure that heating is not interrupted on the coldest days of the year. You can, therefore, guarantee comfortable heating all year, even in the coldest climates.

  • It's important to use a specialized cover designed for heat pumps to ensure that air can still flow through the unit. Covering the heat pump with a tarp or other material can trap moisture and cause damage to the unit.

  • Choosing the right size of heat pump for your multifamily building is crucial. If the unit is too small, it won't be able to keep up with demand, and if it's too big, it will waste energy and money, as well as impact the lifespan of the unit. So, how do you determine the right size?

    The size of the heat pump you need depends on several factors, including the size of your buildings, the climate, and your heating and cooling needs. First, you need to calculate the heat load for your building. This includes factors such as square footage, ceiling height, insulation, windows, and doors. You can use an online heat load calculator or consult with a professional to ensure accuracy.

    Once you have your heat load, you can choose a heat pump that matches your needs. Heat pumps are typically measured in BTUs (British Thermal Units), and you should aim for a heat pump that can deliver the required BTUs for your building.

  • Heat pumps are often touted as a more cost-effective heating solution than natural gas, but is this really the case? The answer depends on various factors, such as your location, the cost of electricity and natural gas in your area, and the efficiency of your heating system.

    In areas where electricity is cheaper than natural gas, heat pumps can be more cost-effective. However, in regions where natural gas is less expensive a natural gas heating system may be more economical. This is likely only in the short term, as the government will further crack down on carbon emissions and start implementing carbon fines on building emissions.

    States like New York City and Colorado already have these fines in place and they are scheduled to increase over time. Gas heaters also come with additional problems such as large amounts of carbon monoxide.

    Additionally, the efficiency of your heat pump plays a significant role in its cost-effectiveness. Higher-efficiency heat pumps can reduce your energy consumption and save you money on your heating bills.

  • Smart thermostats can help you get the most out of your heat pump by allowing you to control and schedule your heating and cooling settings remotely. They can also use sensors and algorithms to learn your habits and adjust your settings automatically to save energy and reduce your utility bills.

    It is important to choose a smart thermostat that is compatible with your particular type of heat pump. You should also make sure to follow the manufacturer's instructions carefully when installing and configuring your smart thermostat to ensure that it works properly and safely with your heat pump.

  • No, you do not need a furnace with a heat pump. Heat pumps can provide both heating and cooling for your building, making them a versatile solution for multifamily buildings.

    In some cases, people choose to keep a backup heating system, as an alternative to an electric resistance heat strip inside the heat pump. For example, in extremely cold temperatures, it is important to include one of these options when you are designing the system.

  • Yes, heat pumps can be installed in old houses. In fact, heat pumps can be a great solution for older homes, as they can provide both heating and cooling without the need for separate systems. However, it's important to note that some older homes may not have the necessary ductwork or insulation to support a heat pump system. In some cases, additional upgrades may be required to ensure proper installation and optimal performance.
