Best 2.5 Ton Heat Pump

The Best 2.5 Ton Heat Pump Guide: Which is Right for You?

Heat pumps are essential to the home, and despite their name, they do way more than heating. They provide humidity control and air conditioning. They work by removing the heat indoors, transferring it outdoors during the summer, and doing vice versa during winter. Due to their efficiency, they have grown in popularity over the recent years.

According to an EIA Survey, over 12 million households in the United States use heat pumps. Also, did you know that if you install a heat pump with an Energy Star designation, you will qualify for a $300 tax credit? Amazing, right? For the average-sized American home, a 2.5-ton heat pump is essential.

This Best 2.5 Ton Heat Pump Guide talks about the best 2.5-ton heat pumps in the market and how they function. We will help you choose the best 2.5-ton heat pump for your home.

How Do Heat Pumps Work?

Heat pumps have been around for decades. They transfer heat by circulating the refrigerant through evaporation and condensation. Like a refrigerator, they evaporate the refrigerant at low pressure to absorb heat from the surrounding. After that, the refrigerant is condensed at high pressure on the other coil to release the heat already absorbed. This process can either heat or cool your home.

Types Of Heat Pumps

There are three main types of heat pumps: air source, split ductless, and geothermal. We recommend that a professional HVAC technician helps you install the heat pump, as you should not do it on your own, regardless of how confident you are in your abilities. A professional HVAC technician will also ensure that you get the right product for your home and needs.

Air Source Heat Pumps

Also known as air-to-air, these are the most commonly used heat pumps. They have an indoor unit (air handler) and outdoor unit (heat pump) that extract heat from the outdoors and transfer it into the home. They also have a refrigerant that circulates between the two units and absorbs and releases the heat back and forth

. The new air-to-air heat pumps can reduce heating costs by up to 50% over baseboard heaters and electric furnaces. They are also better dehumidifiers than the central air conditioners, hence perfect for the summer. Air source heat pumps were only used for warmer climates in the past.

However, with the advancement of technology, they are also used in colder environments such as the Midwest and Northeast regions. Some of these heat pumps have a freeze protection feature that helps keep your pipes from freezing in extreme cold.

Air Source Heat Pumps


  • They are energy efficient.
  • They are cheap to install.
  • They take up little space.
  • They are eco-friendly as heating is not done through the burning of fossil fuels.


  • Their efficiency reduces drastically as the temperature difference between the outdoor and indoor temperatures increases. They do not run efficiently when temperatures are below -4°F or -20°C.

Split Ductless Heat Pumps

These are also called mini-splits. They have two units: an outdoor compressor and around four indoor handlers. They use a compression/expansion cycle to extract heat energy from the outside and transfer it indoors during the cold season. During summer, they do the opposite by removing heat energy from the inside air and taking it outside.

The quiet indoor units are usually installed high on the ceiling or wall and are operated by remote control. If your home does not have ducts, then this is the option for you. Since they do not require ductwork, they are also great for single-room additions. They can also be used to power multiple indoor units; hence individual units can be controlled independently, in what is known as zoning.

  • They are energy efficient as they avoid the energy losses associated with ductwork, around 30% of the home’s energy consumption.
  • They offer design flexibility.
  • They are quiet.
  • They are ideal for homes without ducts.


  • Installing a mini-split heat pump with multiple indoor units is expensive.

Geothermal Heat Pumps

These are also known as ground-source or water-source heat pumps. They use the earth or the ground water as the source of heat in winter and the sink for heat in summer. They move heat through pipes buried horizontally or vertically in loops outdoors.

The tubes have a water solution warmed by the ground’s constant 50-60 degree temperature and circulated into and out of the home. They employ a closed-loop tubing buried below the frost line, and the water/antifreeze mixture circulates through the tubing while gathering heat from the earth. Geothermal heat pumps not only control temperature but also humidity. Compared with a conventional system, they can reduce your home’s energy use by 25-50%.


  • They require little maintenance.
  • They are highly effective in extreme climates than air-to-air heat pumps.
  • They are long-lasting, with their indoor units lasting about 25 years and loops around 50 years.
  • They are quiet.
  • They have low operating costs.
  • They are energy efficient, reducing energy use by up to 50%.


  • They are not practical for small lots and some soil conditions.
  • Installation is costly. However, the initial cost will drop considerably due to the federal and local incentives for installing these heat pumps.

Key Industry Heat Pump Definitions To Know

Below are some of the vital industry definitions you need to know before buying your 2.5-ton heat pump.

SEER and EER Ratings

The SEER (Seasonal Energy Efficiency Ratio) is usually calculated by dividing the cooling output by the energy used by the unit. The higher the SEER rating, the more energy-efficient the heat pump will be. As per the Department of Energy mandate, all heat pumps in the U.S. have a minimum efficiency requirement of 13. Energy Star heat pumps have a SEER rating of between 18 and 27.5. The EER measures a unit’s efficiency when the outdoor temperatures are at 95 degrees Fahrenheit.


The Heating Seasonal Performance Factor (HSPF) is quite similar to the SEER in that it determines the amount of heating in BTUs divided by the total electricity used. The difference is that it also includes calculations for the energy required to defrost the pump during winter and any other backup requirements needed. A higher SEER is more vital in warmer climates, but in colder climates, a higher HSPF is recommended. In Energy Star heat pumps, the HSPF ratings will be between 8.5 and 12.5.


It stands for British Thermal Unit and measures the amount of heat energy required to raise one pound of water to one degree Fahrenheit at sea level. The higher the BTU, the faster the unit can cool the home.

AFUE Rating

The Annualized Fuel Utilization Efficiency (AFUE) rating measures how efficiently a unit uses fuel. The higher it is, the more efficient the pump is.
