Holmes Twin Window Fan

Holmes HAWF3095-U twin window fan

Holmes HAWF3095-U twin window fan

This fan may be a bit too deep at 5.5 inches to allow some users to keep their window screens in, and the expandable adapter doesn’t sit quite evenly with the rest of the unit. There is a small gap between the bottom of the adapter and where it is supposed to meet the window. It also doesn’t have a built-in dust filter or closable vent, so it’s best to make sure that this fan will fit in front of the window screen or take it out when it’s not in use.

Easy Installation

Installation is very easy. It includes adjustable and snap on extender panels and has a very secure fitting design. Fan dimensions are 25 inches by 13 inches, so it won’t fit  the smaller windows, but it will fit even many types of casement windows with a specifically designed bracket that the manufacturer can provide.

The mode button turns the fan on and cycles through three automatic temperature settings. The temperature can be further fine tuned in one degree increments with the two additional temperature buttons. There is no remote with the holmes HAWF3095-U twin window fan, so you have to rely on the thermostat if you want the fan to turn off at night when it gets too cool. When it cycles on and off, the noise is not too disturbing as this is definitely one of the quieter fans on the market.

You can’t just run one fan at a time or individually control their speed, but you can adjust the  fans individually with slider switches to intake, exhaust or one fan doing each for air circulation. This mode is very nice for cooling off a room while removing stuffy air and odors, especially in a hot kitchen while cooking on the stove or using the oven. For bedroom use, it’s good to have the fan on intake at night, and exhaust mode during the day if it’s much hotter outside than it is inside.

Sometimes, when the room temperature reaches close to the desired setting, this fan’s digital thermostat can cause the fan to cycle on and off rapidly, as often as two or three times a minute. If this becomes annoying, the timer function can be used instead. For instance, if you want the room cooled when you first go to bed, but you know that the temperature is going to become too cold to keep running the fan around midnight and don’t want the chill to wake you up, you can simply set the timer for it to turn off. The timer can also be set to turn the fan on a couple of hours before you return home without having to run it for the entire day. This makes a nice feature to get a house ready for the owners to return without wasting electricity.

Holmes HAWF2043 Twin window fan

Holmes HAWF2043 Twin window fan

Holmes HAWF2043 Twin window fan

 I have found that the Holmes HAWF2043 Twin window fan is a feature-rich, cost effective cooling device. It features an easy to use, one touch programmable thermostat that allows me to keep my home at the desired temperature automatically. All I do is press the button corresponding to the temperature I’m comfortable with, and the fan does the rest of the work. The thermostat regulates temperature effectively, and helps save money on energy bills to boot.

One of my favorite features of the Holmes HAWF2043 Twin window fan is that it works for both exhaust and intake. If the air inside is getting stuffy and stale, I switch the fan on to full exhaust to get rid of all of the old air, then change the setting to intake to bring in fresh, cool, comfortable air from outside. Since the Holmes Twin Window Fan,HAWF2043 is actually comprised of two separate fans, I can even set it to do both tasks at once, with one fan pulling in cool air from the outside while the other gets rid of stale air from inside the house. The fan itself does a great job of keeping the air comfortable, and it can also work in concert with air-conditioning by making sure the cool air keeps circulating.

Holmes HAWF2043 Twin Window Fan Features:

  • Digital Speed Settings – The fan has multiple speed settings, which are easy to use thanks to digital controls. Whether I want a real blast of cold air, or just a little bit of circulation to keep things comfortable, I can switch between settings easily.

  • Two-way airflow – As I already mentioned, the ability to operate as both an intake or exhaust fan, and even both at once, makes this fan a versatile tool for home comfort. Switching between the two is also as easy as pressing a button.

  • Serious Circulation Power – What good is a fan that doesn’t have enough power to really keep things comfortable? This fan has all of the power that I can ask for to cool down a room quickly. One of my favorite perks of the exhaust option is for when I use the fan after cooking fried or sauteed foods that create a lot of smoke. Instead of just opening the windows and waiting for the air to clear out, I turn on the exhaust on my Holmes Twin Window Fan,HAWF2043 and the air inside is fresh in minutes.

  • Solid, Sturdy and Safe – The fan is created out of durable plastic, and the fan machinery is water resistant so I don’t have to worry about any rain. The 8.5 inch blades of the fan are well-guarded by plastic shields, so there’s no risk of me accidentally nicking a finger, and no worry when there are kids in the house. Since most of the parts are plastic, it’s also quite easy to move the fan from room to room, as needed.

  • Digital Thermostat Control – With the digital thermostat and display, I can always tell just what temperature the fan is set to. It’s easy to adjust with just the press of a button, and the display lights up at night for easy temperature changing. With the digital control, I feel much more confident in the fan’s temperature regulation than I would with a fan with just a knob and three settings.

  • Adjustable Size – The Holmes Twin Window Fan,HAWF2043 is highly adjustable for fit, so that I can put it in almost all slider and double-hung windows. There is an adjustable screen for width changes, and the fan also comes with seven inch and three inch extenders for further adjustment.

  • Warranty – The fan ships fully assembled, and comes with a three year warranty against any defects in the product. This gives me the confidence to know that my fan is built to last over the long term, and that I won’t be put out financially if something does malfunction. It also shows the company’s trust in their product.

Overall, the Holmes HAWF2043  Twin Window Fan has delivered everything that I expected and more. On many days, it is more than enough to keep the air in my home cool and comfortable. When it gets too hot outside, the fan works excellently in concert with an air-conditioning unit to keep the air circulating. I also appreciate the digital display and easily adjustable settings. With many old fans, getting the temperature and air flow right feels like guesswork. The Holmes Twin Window Fan,HAWF2043 takes away the guesswork, as I can set it to regulate to any temperature I choose, and leave it alone knowing that it will get the job done. Overall, I’d strongly recommend this product to anyone in need of a powerful fan.

Holmes  Twin Window Fan - HAWF2043

Click Here For More Holmes Twin Window Fan – HAWF2043 Review

Holmes HAWF2021 Dual Blade Twin Window Fan is probably the model that can more closely replicate the functions of your average in-window A/C: albeit less powerful as a cooling device, it nevertheless boasts the added advantages of being extremely manageable, easy to install and, last but not least, incredibly inexpensive.”Holmes” is probably one of the most reputed producers of cooling home appliances in the US; with their wide selections of fans, they are fully dedicated in their mission of providing low-cost alternatives to A/C units.

Holmes HAWF2021 Dual Blade Twin Window Fan Features

At a glance, here’s the key features of the Holmes Twin Window Fan HAWF2021, as presented by the manufacturer:

  • Twin blade operation
  • Two-speed setting
  • Manually reversible air flow
  • Adjustable screen; a bonus extender panel is also provided
  • One year limited warranty

Incredibly convenient, incredibly adaptable, incredibly efficient 

I believe that Holmes has indeed managed to create a perfect alternative to your in-window air conditioning, one that is incredibly more convenient, cheaper and definitely more earth-friendly.
The Holmes Twin Window Fan HAWF2021  is available at most retailers (both in-store and online) for around $25-$30.

As I mentioned above, one of the very important features of this fan is its manually reversible air flow: this means that the fan can have two functions, and it can therefore be programmed to either draw cool air from the outside, or to exhaust the hot air from inside the house.
The manufacturer describes the Holmes  HAWF2021 Dual Blade Twin Window Fan as being incredibly quiet as well; this in itself is already a welcome change to your average, ever-so-loud, in-window A/C, something that would make this fan ideal for use in a bedroom or living room, at any time of the day or night.

Sleek and unobtrusive, by design

Its adjustable extender screen and the extra extender panel (which is provided in the box) make it possible for this fan to fit in every type of window; even better, this fan is so sleek that it will allow you to install it while even keeping the window screen in place!
I personally think that this last feature is really interesting, since it saves the hassle of having to “mess around” too much with the various parts of your windows; something that has always been my least favorite part of the in-wall A/C ritual summer installation.

All in all, this sounds like a really great product, at least on paper: but as always, who knows if the real thing will actually meet these expectations?
The only way to find out was to try the product out for myself, which I did: I have to say, the resulting experience was indeed quite a positive one.

My review for the Holmes Twin Window Fan HAWF2021

First of all, what really impressed me was that the fan was indeed very cheap, and I managed to buy one for less than $20 at a major retailer. At a first glance, the product did indeed look quite good; sleek, white, and shiny, albeit a little “basic”, though that had to be expected.
Installation was also extremely easy; the instructions were very straightforward, and the whole process of fitting the device into the window was very much facilitated from the fact that the fan is incredibly light. Again, an experience that is the complete opposite of the one you typically have with those dreadfully heavy in-window air conditioning devices.

As soon as I turned it one, I could see that the fan was probably not so impeccably silent as the manufacturer’s description promised, though it still was not as loud as my in-home A/C unit; therefore, this little setback was definitely not a problem for me.

I was especially impressed by the the exhaust function: unfortunately, my bedroom tends to get really stuffy in the summer, and I was very pleased to feel the temperature becoming way more pleasant within seconds of turning this function on. I’m thinking that I might even try it as an exhaust fan for the kitchen at one point,  that’s how powerful it was.
As for the cooling function, I was maybe a little less impressed with the results: but then again, it is “just” a fan.

Overall, I would definitely encourage anybody to consider buying the Holmes Twin Window Fan HAWF2021, and I would also definitely encourage them to utilize it as much as possible as an alternative to the A/C;  although it might not be a source of sufficient cooling during a heatwave, I think it is definitely powerful enough to provide relief from the heat under normal summer temperatures.
