Heat Pumps are a very efficient way to heat and cool a home; unfortunately, most window air conditioning heat pump units require 220/240 volts to operate.
While 220/240-volt electrical lines can always be installed, this can add to the cost of installing a heat pump unit.
With most outlets wired for 115-volt, a unit that matches this voltage is often the only choice.
With this in mind, some 115-volt heat pump window units are available.
Below are some of the best units we have found. If you have found a good unit, let us know in the comments below.
As always, be sure to read the reviews on Amazon or elsewhere to be sure a unit is a good fit for you.

Our Picks for Best 115 Volt Window Heat Pump Units
- Frigidaire FFRH0822R1
- Honeywell MM14CHCS
- Amana Thru-the-Wall Heat Pump
The Frigidaire FFRH0822R1 is a 115-volt unit that puts out 8000 BTU for cooling and 7000 BTU for heating.
While all window units make noise, it is quieter than many other units and works very well.
It will need a 20 Amp breaker to run from, which is common in most living rooms and bedrooms.
Frigidaire is a well-known HVAC manufacturing company with a good reputation and warranty on their products.
The Honeywell MM14CHCS is a portable heat pump that has a hose connection that feeds out a window.
This is a unit that would be easier to set up as a hose is simply fed outside to pump out hot or cold air.
It is also not a permanent fixture and can be easily carted away to a closet.
Amana makes this 115-volt unit that is rated at 9,000 BTU.
It has a SEER rating of 10.4 that, while not as good as other options, is expected for a pre-setup all-in-one package.
The unit fits into a wall and is commonly used in motel rooms that need heating and cooling for individual rooms.
Summary
Although most window heat pumps are 220-volt units, a few are dedicated to 115-volts.
Keep in mind other electronics that may be on the same circuit as the outlet you plan to use.
Units like that above are likely to draw 10-20 amps. If there are other electronics on the same circuit breaker, it will flip off if the amps are exceeded.
One way to tell what outlets are on the same breaker is to plug into the outlet with an electronic device such as a radio and turn the breaker off. Other electronics on the breaker will also go off, giving you an idea of what is being used.
Also, heat pumps have a low-temperature rating, which means they can work and pump out heat. This can vary from unit to unit.
Most heat pumps can work down to 20 degrees Fahrenheit without any problems. Below this and the outside condenser can begin to ice up. When this happens, most will use heat strips which work like a big space heater to send out heat.
If the temperature does drop low enough for the heat strips to come on, it should only be temporary while the condenser becomes unfrozen.
