Our Picks for Best Window A/C Units That Heat and Cool

Window AC Units That Heat and Cool

Window-mounted air conditioning units that both heats and cool come in two styles.

  • Heat Pump Air Conditioner Combination
  • Supplemental Heat Air Conditioner Combination
  • A Heat Pump works by cycling refrigerant the same as any A/C unit does. When it becomes cold the process is reversed and it produces heat instead of cold air.

    Supplemental heat is an A/C unit that has heat strips installed. Heat Strips work on the same principle as a space heater using elements that become hot in combination with a fan that blows out hot air.

    Each of these types of systems has their positives and negatives.

    Heat Pump vs Supplemental Heat

    • Heat Pumps are more efficient and use less electricity but cost more to buy than a unit with supplemental heat.
    • Supplemental heat units cost less to buy but use more electricity and cost more to operate.

    Since units that use heating elements to heat a room like a space heater, they are often installed simply to free up space with no other real benefit.

    Each type of unit has its own benefit that needs to match the scenario.

    There are many units available with those listed below some of our picks.

    As always be sure to read the reviews on Amazon or elsewhere to be sure it is a good fit for your home.

    Our Picks for Best Window A/C Units That Heat and Cool

    1. LG LW1216HR
    2. LG 12,000 BTU 230V Window-Mounted AIR Conditioner with 11,200 BTU Heat Function

      LG Electronics makes this 115 Volt window unit that heats and cools using supplemental heat.

      It is rated to heat and cool a space up-to 320 sq. ft.

      Since it uses supplemental heating when it is cold out the unit will work like a space heater mounted in a window.

    3. Koldfront WAC12001W
    4. Koldfront WAC12001W 12,000 BTU 208/230V Heat/Cool Window Air Conditioner

      This unit from Koldfront uses 220 volts to operate which supplies more heating and cooling compared to many other units.

      It is rated at 12,000 BTUs and for a room 450- 550 sq. ft. in size.

      220 volts is not commonly in every room and is usually only used by a dryer or electric stove.

    5. Frigidaire FFRH0822R1
    6. Frigidaire FFRH1822R2 18500 BTU 230V Median Slide-Out Chassis Air Conditioner with 16,000 BTU Supplemental Heat Capability

      This heat pump unit from Frigidaire is a 230 Volt 18500 BTU package.

      It can heat or cool a small room up-to 1170 sq. ft.

      It uses supplemental heating units.

    Buying a Window mounted air conditioning unit that heats and cools a room comes down to the type of heating you want the unit to do.

    Electric heat works great but can be more costly in the long term.

    Heat Pump units while more efficient can be more costly to buy upfront.

    The installation will be the same with whatever type of unit is bought, first by making sure the wall outlet is the correct voltage type, and then the window dimensions are correct for the unit to fit.

    For a more long term solution Heat Pump units called Mini Split units can be installed for better long term solutions. Mini Split units separate the condenser and compressor with a line that recycles the refrigerant away from a home.

    This makes them much quieter and better built than a packaged window unit.

    Since Mini Split units are also Heat Pumps they can heat or cool a space very well. Of course, the cost of a mini split is much greater than a window unit and installation is much harder.

      Bought a house with a Friedrich heat/cool AC in the master bedroom addition. The unit is probably about 30 years old and just went out! Looking at replacing it and would love another Friedrich but they cost so much!!! Like you said, you get what you pay for!

      We have that Frigidaire 8000-Window A/C that heats and cools. Nice machine, but we didn’t ever Use the Heat because the booklet didn’t explain how to use it, or its purpose. It never blew a whole heap of AIR out of itself in the summer-but it cooled. That A/C is a mystery to us.
