What’s a heat pump?

Heat Pump

Heat pumps are by no means a recent invention, as first attempts to transfer thermal energy from a cooler to a warmer space have been made as early as the mid-19th century. These devices can either cool or heat an entire home or a single room, depending on their size and how they’re used.

They’re generally utilized as a replacement for conventional HVAC systems in regions with moderate climates. A unit relies on a refrigerant that circulates between the outdoor compressor and the indoor fan coil to redistribute the heat.

It is worth pointing out that heat pumps cannot generate heat, so while the unit is in the heating mode, it collects the heat of the outside air and releases it into the home’s interior. In the cooling mode, the unit does the opposite, as it gathers the heat from the inside of a house and releases it outside.

The key components of heat pump systems are:

  • An outdoor unit equipped with a coil that serves as an evaporator or condenser
  • An indoor unit that features a coil and a fan that keep the air inside of a home circulating
  • A refrigerant that releases or absorbs the heat
  • A compressor that pressurizes the refrigerant
  • An expansion valve is tasked with controlling the flow of the refrigerant through the system.

Types of heat pumps

The exact components of heat pump systems depend on the pump type, and the system we described can either be a ductless mini-split or an air source. However, these aren’t the only types of heat pumps; geothermal, dual fuel, or solar-assisted models are also available.

Each of these systems utilizes different sources to heat or cool the air, and you should also keep in mind that some heat pump systems can be connected to furnaces in case they’re used for heating purposes.

Let’s take a look at the most common types of heat pump systems.



Instead of relying on the air, the geothermal heat pump features a loop pipe system installed several feet under the ground level. A water solution heated by the ground’s or well’s thermal properties circulates through the loop pipe system providing the cooling, heating, or humidity control for the entire structure.

Geothermal heat pumps exceed the needs of homeowners searching for models with 2-ton outputs as they’re usually designed for large venues. Read our guide through the humidity control systems for further information on how you can control humidity levels in your home.

Ductless mini-split

Ductless mini-split

As their name indicates, ductless mini-split heat pumps don’t require ducting to heat or cool a room. These systems contain indoor and outdoor units connected by flexible tubing, enabling the refrigerant to move between the two units.

Their power output depends on the model, but finding a 2-ton ductless mini-split heat pump shouldn’t be difficult.

Air source

Air source heat pump

This is by far the most common type of heat pump. The outdoor and indoor units move the air outward or inward through the tubing that connects them. The refrigerant in the system either absorbs or releases the heat depending on the heat pump’s current mode of operation.

Dual fuel

Dual fuel

These hybrid systems are perfectly suited for climates with stark temperature differences between the winter and summer months. Dual fuel heat pumps draw heat from a furnace while they’re in the heating mode, and they utilize air for cooling purposes.

In addition to being energy efficient, these systems have varying output capacities, so you can choose a model that is best suited for your home.

Understanding the output capacity ratings

The heat pump’s output is measured in BTUs, so for instance, a system with a maximum output of 56.000 BTUs can cover areas of up to 3.100sq/ft.

However, companies use another metric for the heat pump systems with output capabilities of over 10.000BTUs per hour. A heat pump system with 12.000 BTUs is sometimes labeled as a 1-ton heat pump, while a model with 18.000BTUs has 1.5 tons.

Manufacturers don’t always include the heat pump’s output in the specifications, and they opt to replace it with the unit’s seasonal energy efficiency ratio.

Although the 14 SEER should be the equivalent of a 2-ton heat pump, this isn’t always the case, and you’ll encounter models with SEER ratings ranging from 10 to 21. That’s why you need to go through the specifications of the heat pump system you’re interested in to determine its exact power output.

Compatibility with other HVAC systems

Depending on the heat pump type you choose, you may or may not be able to pair the heat pump with other HVAC systems in your home. Most models have moderate heating capabilities, which is why heat pumps can’t replace a heating system in cold climates entirely.

Dual fuel heat pumps are your best option if you need a system that can heat or cool your home efficiently because they’re compatible with furnaces that serve as their source of hot air.

It is advisable to consult with an HVAC technician on the heat pump’s compatibility with other HVAC systems in your home to find out if connecting them is possible.

It is also worth pointing out that taking steps to increase your home’s energy efficiency reflects positively on the performance of the heat pump unit. Go through our guide to heating systems for more information on how these systems work.

The most important factors to consider while choosing a 2-ton heat pump

The specifications of different heat pump models can seem incomprehensible and confusing to someone who hasn’t encountered terms like SEER or single-stage compressor before.

In addition, assessing how difficult it will be to install a heat pump model in your home just by looking at its specification list is nearly impossible. That’s why you should seek different opinions before you decide to control cooling and heating in your home with a heat pump unit.

We’ve shortlisted some of the most important factors you have to keep in mind while searching for a 2-ton heat pump, so let’s take a look at them.

Coverage area

2-ton heat pump

A 2-ton or 24000BTU heat pump can cover areas from 800ft to 1300sq/ft under ideal conditions. However, seemingly insignificant factors such as the height of the ceiling or the number of doors and windows a room has can affect the size of the system’s coverage area.

Besides, whether or not a 2-ton heat pump will provide sufficient heating or cooling for a 1300sq/ft. the area depends on your home’s energy efficiency since spaces with poor insulation might require higher outputs.

Noise level

Heat pump systems are generally not very noisy, as most of them operate within a 40dB to 60db radius. A unit’s noise level depends on the distance from the unit, so the same heat pump can produce 56dB and 65dB of noise depending on how far away from it you are.

That’s why you have to pay attention to the size of the room in which the indoor unit is going to be installed since models that generate more than 60dB of noise can be too loud for small rooms.

Seasonal Energy Efficiency Ratio (SEER)

2-ton or 24.000 BTU heat pumps don’t have identical energy efficiency ratios, as their SEER rating can vary from 10 to 21. States throughout the country have different SEER rating standards, and depending on the state you’re living in, you’re going to need a heat pump that is 13 SEER or 14 SEER rated.

A Heating Seasonal Performance Factor or (HSPF) measures the unit’s energy efficiency, and the minimum HPSF for a heat pump is 7.7 HSPF. So, the heat pump you chose should have a 15 SEER and 8.5 HSPF to provide you with an efficient, energy-saving performance.

Installation process

Installing a heat pump isn’t a simple DIY task since even the simplest of units require extensive knowledge and experience. The ductless mini splits are the easiest to install, but even so, a team of two HVAC technicians needs around five hours to complete the job.

The installation process of air source heat pumps usually lasts for several days, while the thermal heat pumps require pre-installation analysis to determine if it is possible to install the loop pipe system.

Cost and warranty period

Heat pumps are durable, and most manufacturers offer 5 to 10-year warranties for all parts of the system. However, exposure to low temperatures can cause a heat pump to freeze and affect its projected life span.

The price of a heat pump depends on the complexity of the system and its SEER rating, so a high-end air source model with a 15 SEER rating can cost over $10.000, while most heat pump systems are within the $2.000 to $8.000 range.

The advantages of heat pumps

  • Excellent cooling capabilities: All heat pumps, regardless of the type, can cool large or small spaces with the same efficiency level. The system absorbs the heat from the air in a room and replaces it with fresh and cool outdoor air.
  • Reduced power consumption: Unlike the conventional HVAC systems that inflate the electricity bill during warm summer months, heat pumps lower the power usage in your household while keeping the temperature at an optimum level.
  • Noiseless operation: The vast majority of heat pumps are equipped with technologies that lower the amount of noise they generate. Consequently, these systems won’t cause disturbance to your family members or your neighbors.

The disadvantages of heat pumps

  • The performance is influenced by the climate: Heat pumps are a poor fit for regions with long and cold winters, as they struggle to keep the room temperature at a comfortable level if the outside air temperatures drop below 40F.
