Some think it is far easier to save on energy if you own a house. After all, you have *almost* complete control over appliances and how they run in a house. And there is a certain degree of truth to that. You have greater responsibility over the appliances and their upkeep, but if something goes wrong, you can turn off the unit altogether and come up with an alternative solution – or replace it.
Apartments or specifically the renters that reside in them don’t have those burdens – though they are …

Fixing your window air conditioner instead of replacing it saves you money, hundreds possibly. Chances are, a rattling or noisy air conditioner unit is due to faulty installation, a loose part, loose or worn window frame, loose window panes, loose filter (or wrong filter size), fan obstruction, loose front or side panels, or the condenser coil hitting any moving part (such as the fan).
The good news is you can repair all these.
Faulty Installation
We’re all human, and in the course of “being” human, we’re going to mess up installing something. I’ve …

Well without seeing the unit, there’s a small handful of things that could go wrong with the window unit air conditioner.
Is it dirty?
Believe it or not the number one cause of window unit air conditioner malfunction is dirty or grimey coils or condensers. The symptoms range from the unit smelling musty or blowing dirty air to the condenser not turning on at all even when the a/c unti is supposed to turn on (request for cooling was sent by the thermostat.) The fix is simple: clean the coils. Take a …

There is a natural tendency for people, especially Americans, to always opt for the biggest and best air conditioner they can possibly afford. The going thought is, the bigger the unit (as long as it fits in the window), the better it will work. It will cool the room faster, and thus use less energy.
This isn’t the case.
A professional knows what the homeowner doesn’t. In this instance, the right sized air conditioner should be selected for the room it will be placed in.
Under most circumstances, the btu, or cooling power, …

When a portable air conditioner that is in good working order senses (through a thermostat) that the temperature of the air in the room is too high, or above the threshold set, it begins the cooling cycle. Modern window unit air conditioners typically operate in “dual” phases – and cool using one of the phases. This is set at the factory to ensure the most efficient use of energy.
The first phase uses the internal fan. When the fan turns on, air is blown into the room to circulate it. The …

Before you plug in the AC and crank it up, there’s some things you can do to keep it running efficiently.

clean it. Remove the filter and clean it out, even if it looks relatively clean. A dirty or partially clogged filter can reduce efficiency dramatically.
wipe it down. Using a cloth, carefully wipe the outer coils or grill. (Be very careful – the grate is very sharp and can slice easily!)
inspect it. After you remove the filter, check the area around the compressor and coils. Vacuum it out if it is …

The number one cause of air condioner problems is compressor failure. When this happens, a professional needs to contacted to replace the compressor. However, many other air conditioner problems are a little simpler and easier to troubleshoot.
But a dirty filter can make the unit behave like there is a compressor problem. When the filter is dirty and air flow into (and our of) the unit is severly limited, in most air conditioners the compressor will not turn on. This is because there is insufficient circulation for proper efficient operation. And …

Finding and setting the optimal temperature may be a science in itself. You have to take into account the heat you use with your comfort level based on your activity.
For example is it necessary to have the heat turned way up at night while you’re asleep in your bed?
Do you need the heat turned off at any time?
You need to find the balance that suits you best.
I suggest playing with it some, but don’t make it too high or low.
In the winter set it no higher than 68 or 70 …

Basically, make sure the thermostat location isn’t too hot, or too drafty. The thermostat measures the temperature and locating it in either location can throw off the reading.
The effects can be disastrous for your utility bill.
The area might be warm, so the thermostat will be tricked into thinking the heat has done its job and turn it off. Actually, just the area where the thermostat is located is warm because it is directly over or very close to a heating vent.
The opposite is true as well. If …

Perhaps you have a few window air conditioner units for a few rooms of your house, rather than having central air.
That’s fine. In fact, it is much cheaper to operate if you stay in a couple of rooms most of the time.
Make sure they are working properly and efficiently. Most of them today are built to run pretty quietly. So if your unit starts …
