Frequently asked questions about the Best Window Air Conditioner With Heat

How does window AC with heat work?

Due to the increased cost of running multiple appliances, many people are opting for ‘all-in-one’ units. These units are more efficient with power. They are also able to reuse some compartments to achieve desired results.

One such appliance that is rapidly gaining popularity is the window air conditioner with heat. Unlike the conventional window AC, this unit is both useful both during the summer and the winter. This is because it is capable of adding removing heat from the house as demanded by the user.

In many parts of the world where there are extreme winters and summers, such a unit is useful. This reason is it can help keep indoor temperatures in constant levels no matter the weather outside.

The Heat Movement Cycle

In the HVAC world, heaters, refrigerators, and air conditioners are referred to as heat pumps as they move heat from one place to another. To cool the house, a refrigerant is used to move thermal energy from one part of the system (usually inside the house) to another, where it releases it.

For this to be achieved, a number of components have to be present. These include;

  • Compressor. Here, the refrigerant (or the coolant if you will) is pressured and turned into a hot, high pressured gas.
  • Condenser. This part receives the squeezed gas from the compressor and passes it through a long thin coil tube. As it travels through the tube, it loses most of its heat energy. This heat loss is further accelerated by the use of a fan that blows cool air past the coils. This section faces the outside so that the dissipated heat does not go back to the house.
  • Expansion valve. As the coolant loses heat, it slowly turns back to a liquid and an expansion valve is used to help speed this up.
  • Evaporator. The coolant is then pumped here where it is subjected to less pressure and turns into gas as it pulls heat energy from the air. This section takes away heat from the air and the resulting air is much cooler than before. This cycle is repeated until the desired levels are achieved.

The reversing valve

A valve is used to reverse the above-discussed process and help warm the house instead of cooling it. It changes the direction of flow of the coolant whereby the condenser coils become evaporator coils and vice versa.

Warm air is thus drawn into the room while cold air is expelled. This gives this type of window air conditioner the ability to use much less energy since it is only taking advantage of natural thermodynamics.

The reversing valve changes its orientation to reverse the flow of the refrigerant.

110/115/220 volts: what voltage for my window AC with a heater?

Window air conditioners need to be plugged to a proper voltage source for them to work properly. These units can put a lot of strain on domestic electric systems or may not even work properly as intended.

Most households’ outlets are wired from 110/115V power sources. This makes using smaller window air conditioners with heat suitable for low voltage the only choice. Luckily, there are many appliances that work well with such voltage and so this should not be a big deal.

Heat pumps, especially those that provide more than 15,000 BTUs, draw as much as 20A from the power source. Keep in mind there may be other electronics plugged to the same power. Making sure you have a 220V power source before buying such a power-hungry machine could save you a lot of hassle.

Can I find window air conditioners with heat at Walmart/Lowes?

Walmart stocks a lot of these from big brands like TCL, Haier, LG, Frigidaire, CE, and many others from as below as $100 to more expensive ones like Friedrich’s smart Kuhl Plus YS10N10B 26″ that goes for over $2000.

Lowes also stocks from most of these and other big brands and you will surely get a unit that suits your needs be it an ultra-quiet or a smart unit.
