Window mounted Air conditioning units that heat and cool come in two styles. 1.. Heat Pump Air Conditioner Combination 2.. 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 a A/C unit that has heat strips installed. Heat Strips work on the same principal 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 have their positives and negatives. Heat Pumps are more efficient and use less electricity but can cost more than a unit with supplemental heat. Since units that use heating elements to heat a space like a space heater they are often used simply to have more room instead of a bulky space heater taking up space.

Buying a Window mounted air conditioning unit that heats and cools 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. Installation will be the same with what ever type of unit is bought, first by making sure the wall outlet is the correct voltage type, and than 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. As always be sure to read the reviews on Amazon or elsewhere to be sure it is a good fit for your home. Asked on: August 28, 2014 by Beverly H., Weston Which A/C fan setting costs more, “on” or “auto?” My friend believes the “auto” setting uses more electricity. That’s actually a common, but important question. The on/auto fan switch on your A/C thermostat will affect the price you pay to cool your home. The A/C fan circulates the cooled or heated air throughout your home. Setting the fan switch to “on” will make the A/C fan run continuously, 24 hours a day. Choosing the “auto” setting will cause the fan to shut off with the rest of the cooling system as soon as your desired temperature on your thermostat is reached. Fan “on” costs more Advice from friends can be helpful, but in this case your friend was mistaken to think that the auto setting used more electricity.

Let’s assume your air conditioner normally cycles off 30 percent of the time. In this example, turning the fan switch to “on” will make the fan run over 200 extra hours a month. For a typical size central air conditioner, that would cost you about $8 more each month. Keep in mind, a fan that runs all the time may also wear out sooner. Another reason to keep it on “auto” Setting your A/C fan to auto also helps provide better dehumidification. Have you noticed how moisture from the air condenses on the outside of a cold drink on a humid day? Your A/C unit captures moisture the same way, helping your home feel more comfortable. When the fan cycles off using the auto mode, moisture has a chance to drip from the cold cooling coils into the condensation pan and then drain outside. However, when the fan runs all the time in the “on” setting, less moisture has a chance to drip and drain outside. Instead, some gets blown back into the air again. Some people prefer the feel or sound of the fan running all the time.

If that’s you, at least now you know how much that choice will cost you.
