Why a Window Air Conditioner with Heat Pump Makes a Good Investment
Typical window air conditioners cool the room. They are only used when the temperatures get unbearable in summer. However, during the cold season, you’ll need an electric space heater to supplement your central unit or warm up a small room that you occupy. And that is an extra investment.
With window air conditioners with heat, you have control over your indoor environment all year round. But that’s not all you benefit from these types of units.
Here are the reasons why a heat and cool window air conditioner makes a good investment
– Perfect for Small Spaces
If you rely on your central unit during the months with extreme temperatures, you’re aware that some rooms always require a little bit more time to reach the set temperature. As a result, you end up closing them or spending a lot of energy to cater for the extra time it takes for you to feel comfortable in these rooms.
Installing a window A/C unit is perfect for these small spaces, such as the upstairs rooms, converted garages, or attached guest house. This is because the unit cools/warms the rooms within a short period. Also, you don’t have to close them off to save energy.
– Quiet and Easy to Install
One of the reasons some homeowners don’t prefer installing window air conditioners is the loud noise they produce. However, things have changed, and windows AC are no longer noisy. The quietest window air conditioner will make less white noise than the hum of an average refrigerator.
Also, installing a window air conditioning system is easy, and no costs are involved. They are portable and easy to set up. If you have a little homeowners DIY experience, then it is easy to follow the installation manual and have your unit set up in a matter of a few minutes. You need to make sure they rest on a windowsill and have a standard electrical wall outlet where you can plug the cord.
– Packed with Energy- and Money-Saving Features
Like many other types of air conditioners, window AC units have various energy and money-saving features. One of the essential features that make new models more efficient to run than older window models is a programmable thermostat. It allows you to preset the unit to turn on when the temperature is below your preferred room temperature and turn off when the temperature exceeds the set levels.
Before choosing an energy efficient window air conditioner, you need to be aware of the size that will perform well in your space. An air conditioner with heater should be powerful enough to remove the hot/cold air in the room you want to warm/cool. If you select a small undersized unit, it will have to work twice as hard to cool/heat the room. Therefore, it will take more time to reach your desired temperature, creating a waste of energy. On the other hand, a large oversized window AC will cycle on and off more frequently than heating and cooling, which also wastes energy.
– Reduce Hazards
Unlike portable space heaters, window ACs with heat are safe to use. Following all the safety tips laid out by the manufacturer for using a space heater are all great, but the fact of the matter is there is a less potential risk for using a window ac than a portable space heater.
Some of the things you need not do with a space heater is leaving them unattended, running them in rooms with small children or pets, or spaces with potential for dampness like bathrooms or kitchens. Also, trailing cords can create tripping hazards.
Installing a window air conditioner with a heater not only keeps your space at the temperature you desire but also eliminates these risks you have to be worried about when using a space heater. Moreover, you don’t have store your unit when the temperatures moderate or enter a different season of the year. That means you don’t have to store an air conditioner when summer ends or space heater when winter ends.
How to Choose the Best Window Air Conditioner with Heat Combo [Buyer’s Guide]
Now that you have decided that a window air conditioner is a perfect unit for your home, how should you go about choosing one? Well, many factors determine the unit you select. Here are the main factors to keep in mind before choosing the best window air conditioner brand.
Only a few people in the world can make purchases without considering the cost. If you’re not one of them, then you need to figure out how much you’re willing to spend and stick to it. What’s important is to find the right balance between what you can afford to pay and what you need.
Typical window air conditioner prices range between $100 to over $2,000, which is a huge difference. Most low-end units have basic features and ideal for cooling/heating small spaces. High-end units cool large rooms and tend to have numerous features and functions. If you are looking for cheap and reliable options, you can check our review for the best cheap window air conditioners under $100.
Apart from the initial purchase price, you need to consider how much it will cost to use the unit. What would be your energy bills and maintenance costs over time? Air conditioners have been found to use a lot of energy. Most homeowners spend half of their total energy bills on heating and cooling. For that reason, investing in an Energy Star rated model is a good move towards saving a good amount of money over years of use.
– Cooling Capacity
The cooling capacity of heating and air conditioner window units should be given at least as much weight in your consideration as the cost. To determine how powerful your AC should be, you need to measure the size of your space.
The amount of power a window air conditioner offers to remove hot air from your room is measured in British Thermal Units, or BTUs, per hour. A unit with a high BTU rating is more powerful and performs effectively in large rooms. Low BTU ratings mean the air conditioner is less powerful and best suited for small rooms.
Usually, when you’re perusing air conditioner options, it’s crucial to select a unit that has a BTU level designed to fit your space. If you purchase one with too little BTU rating, then it’ll have to run continuously for long hours to keep the area you are using cool and comfortable. As a result, it consumes a lot of energy, and still, sometimes it doesn’t reach your desired temperature level. If you choose one with a high BTU rating, it will cycle on and off frequently without cooling the space evenly, leaving your room air susceptible to uncomfortable hot and cold pockets.
The chart below will help you determine your ideal cooling capacity. All you need to do is measure your space and choose the right amount of BTUs. For slightly large rooms, look for the best window air conditioner for large room.
– BTU CHART BASED ON ROOM SIZE
[wpsm_comparison_table id=”9″ class=””]
Keep in mind that some factors will affect the distribution of cold air across the room. So, you need to take them into account as well. Some of them include:
- Ceiling height: the estimates recommended above are ideal for rooms that have an 8-feet ceiling height. If your room’s ceiling height is more than 8 feet, you may want to increase the BTU level.
- Sunlight: you need to increase your BTU power by 10 percent if your room experiences excess heat or direct sunlight.
- The number of people occupying the room: it’s recommended that you add 600 BTUs for every person that occupies the room.
- Kitchen: Add 4000 BTUs if you’ll be installing the window AC in the kitchen.
– Window Type
Just from the name, window air conditioners should be installed in a window. Before choosing a window unit, you need to check the type of window you have. Some can fit vertically or horizontally, while others can be installed on sliding or casement windows. For these types of windows, we have reviewed some of the best casement window air conditioners on the market.
What you must avoid is installing a window air conditioner through the walls. Find out if the model you have chosen has both window and wall installation options. If it is only meant for windows, don’t attempt installing it through the walls because the process may be hectic and the unit may not fit properly.
If you decide to install it in a window, make sure you have the measurement of your windows. This is important because most window air conditioners manufacturers provide the maximum and minimum window sizes in their instruction manual, so you have to make sure the model fits your window size.
The next important thing to keep in mind is the position of the window AC. How far will it be to a power outlet?. Different models have different electrical requirements. Powerful units will require a higher-voltage outlet while a less powerful unit will operate off the standard household outlet.
Additionally, make sure the window, where you prefer to install your AC, is in the shade to avoid wastage of energy.
Window air conditioners make some sounds that are attributed to their normal operation. The noise level isn’t usually distracting, and you should be able to go about your business whether you’re working in your office, relaxing in your living room or sleeping in your bedroom.
However, not all window ACs are created equal. Some models can be noisy than others. What you don’t want is an air conditioner that makes it hard to go about your daily duties, which is why you need to choose a quiet air conditioner.
Generally, window air conditioners are a little bit louder than other types of ACs. Since it’s not easy to tell how noisy a given model will be, choose a window AC from a reputable manufacturer. Also, not all manufacturers include noise measurements (decibel readings) on the units. If you are not sure about a specific model that you like, check the reviews of other customers who have used it so you can have a better idea of how loud it will be. We have also reviewed the quietest window air conditioners.
– Energy Efficiency
It’s common for homeowners to experience an increase in their electricity bills when they decide to use an air conditioner. This is because air conditioners use a lot of electricity, no matter what type you buy.
Amongst the different air conditioning options, windows ACs are not the most energy efficient. However, since they are designed to supplement your central unit or cool small rooms, they may turn out to be energy efficient than central air.
If you’re concerned about the potential energy usage of your window air conditioner, look for energy star rated units. These type of units have been proven to use less energy, approximately 20 to 50 percent less than others. Another feature to check is the Energy Efficiency Ratio. It will help you determine how much electricity an air conditioner will require to cool a specific room capacity in an hour. The higher the EER rating, the more efficient the air conditioner.
Do you want to minimize your electricity bills? If so, it’s a good idea to choose an AC that has energy saving features. Find a unit with a programmable thermostat that will allow you to set your desired temperature. And when the temperature is reached, the unit maintains it without using more energy. Another feature is a programmable timer that lets you set the unit to run when you are home and turn off when you’re away from home. So, you only use the unit when it’s needed.
– Electrical Requirements
Unlike other common household appliances, window air conditioners are more powerful. Therefore, you need to make sure your electrical system is designed to provide the proper voltage, or you risk blowing a fuse or the unit not working to it’s cooling or heating potential.
After choosing a specific model, check its specifications to find out its electrical requirements including voltage, amps, and watts. Many manufacturers list or picture the correct plug face type, and you can find in its NEMA (National Electrical Manufacturers Association) classification.
Overall, 115-, 125- or 220-volt circuits will serve most room air conditioners perfectly. If the AC cooling capacity is below 15,000 BTUs, it can operate on standard residential (115- to 125-volt) circuits. If the cooling capacity is more than 15,000 BTUs, it ideal to use 220-volt circuits. If you’re unsure of anything, seek out the help of an electrician.
– Ease of Use and Maintenance
Somebody’s going to have to control the unit, whether it’s adjusting the thermostat, timer or changing the modes. If it’s difficult to figure out how to use it, you may run into problems. For the most part, window air conditioners are easy to operate and use, so the controls shouldn’t be confusing at all. If you are worried that the controls of a particular model may be complicated, it’s wise to choose another unit.
Another vital factor to keep in mind is window ac maintenance and the cost involved. Find out how often you’ll need to clean the filters and the AC unit as a whole and how complicated the cleaning process is. Choose window air conditioners with a slide-out chassis because the slide out function makes them more accessible thus easing the cleaning processing.
– Ease of Installation
Most window air conditioners shouldn’t be difficult to install. However, some will need more work than others depending on your window type. Since it’s difficult to tell how much work a model requires to install, one of the best sources for knowing what to expect is reading other customers reviews. If you see positive comments about how easy it is to install, then you know it’s for you.
Window air conditioners are a massive investment, and you want to make sure you get the most out of it in the long run. Most window air conditioners have similar service lives, but their longevity depends on use, maintenance, and proper storage.
Additionally, reputable air conditioner brands have a good name on the market because their units have proven to be reliable and durable.You can know a model is durable and reliable by checking the warranty offers. You want to make sure the warranty is extended enough, and the manufacturers offer to help you out with any fixes if need be.
Features of a Good Window AC with Heat
Some window air conditioners have extra features that make them simple to operate, maintain and help minimize your operation cost.
Most contemporary units have these features, but not all of them. So check if your window AC has these features to improve your cooling and heating experience.
A programmable thermostat allows you to set the unit for the precise temperature you want. This is important, especially if you like your room temperature at a specific level but don’t want your AC running all day long. Once the temperature is reached, a shut-off feature will automatically cycle the unit on and off to maintain the selected temperature. Most new window air conditioner models feature a digital display that shows you the preselected temperature and the actual temperature. This readout is not only convenient but also more accurate and maintains a more consistent temperature in the room. If you decide to purchase a basic model, you’ll control the cooling output using a mechanical thermostat. This involves adjusting the temperature using a dial found on the control system of the unit.
A programmable timer gives you the control over the amount of time you want the window AC to run. That means you can set a delayed start or stop time depending on what you want to achieve. If you’re going to come to an already cool home, you can set the AC to run a few hours before you reach home. Also, you can set it to turn off when you leave for work. Therefore, the unit only runs when you need to cool the room, helping you manage your energy consumption.
Air conditioners are fitted with control functions that make it easy to operate them. A remote control is one of these functions that offer you a more convenient operation. It allows you to adjust the temperature, set the timer, select the operating mode all without having to stir a step. Some air conditioners have an inbuilt magnetic hold that ensures the remote is secure and neatly displayed where you want it.
Adjustable Fan Speed
You can take advantage of the fan mode to help blow the cold air from the air conditioner or circulate room air when cooling isn’t needed. Whichever option you choose, the fan offers a variety of speeds that eventually affect the rate at which your rooms cool down. Most air conditioners will either have two or three fan speeds. Keep in mind the fan speed you choose affects the level of noise produced by the unit. In a hot summer day, you can use the high speed to cool the room quickly. However, when you’re sleeping, selecting low speed ensures your sleep is peaceful.
Energy Star Rating
Aside from the programmable thermostat and timer, another feature that can help you save energy is the energy star rating. Most energy star rated units can save up to 10-30 percent of your total cooling and heating usage.
Air Direction Control
You want to make sure the cold or hot air is blown to the direction that needs it the most. A good AC should have adjustable louvers so you can manipulate the direction of the cool air from the unit. If your window air conditioner is installed in the living, make sure it is positioned strategically so that it cools or warms the room evenly. You should also be able to optimize the airflow especially in those spaces where you utilize a room or ceiling fan.
Depending on the type of filter your AC uses, you need to be up-to-date with when your air filter needs cleaning or replacement. Find out if your unit has a standard filter or washable filter. Standard filters need to be replaced from time to time while washable can be cleaned and reused.
How To Install Window Air Conditioner Unit with Heat
Window ac unit with heat must be installed properly for them to cool your room.
A window air conditioner is fairly easy to install. As long as you have all the components, you can do it yourself in less than an hour.
This guide is a step by step guide of how to install a window AC through a window.
1. Choose the Right Location.
Make sure the position where you want to install the unit is close to the center of the room and on the shady side of the house. Also, the location of the AC must be close to an outlet to avoid using an extension cord. If you want to use an extension, make sure it is rated for window air conditioner use.
Prepare and inspect the window and surrounding area.
Inspect if the window is in excellent condition. Damaged or rotting window sills and slashes need to be repaired before installing the unit. If not, the window may present a safety hazard should the unit fall due to disrepair.
The surrounding area should be free of obstacles, and anything that interferes with the installation process must be removed. In some cases, you may need to remove storm window frames and window screens entirely.
2. Install Brackets if Required
Depending on the windows you have and the unit you purchase, you may need to install a bracket that attaches to the outside of the house. Use metal screws when installing these into metal frames or wood screws when installing into vinyl or wood.
3. Position and Secure the AC Unit in the Window Opening
At this time, the window should be ready, and you can place the unit into the window opening. Before positioning the AC, read the owner’s manual to get an idea of the angle you need to position it.
Most installation manuals will tell you to open the window to provide enough space for the placement of the unit. Next, the accordion panels must collapse inward to avoid interfering with the initial position. After placing the air conditioner in the opening, lower the top sash to hold it in place.
Once the unit is in the right position, the next step is to screw the accordion panels into the bottom slash. But before that, make sure you expand the accordion panels outward into place to reach the edges of the window. Drill pilot holes in the bottom of the slash to prevent the wood from splitting.
Next, if your unit comes with angle brackets, you need to fasten them to prevent the window sash from moving upward after the air conditioner has been installed. If there are no angle brackets, you can use stock to wedge between the window sash and frame. Make sure you measure the length from the bottom of the window sash to the top frame of the window.
4. Weatherproofing and Insulation
When all is done, and the window is left open, you’ll see a gap between the two panes of glass. Most window AC kit includes foam weather stripping that you can use to seal the opening. You can also purchase it from your local hardware store. If you install the unit on the side of the house that receives a lot of rain or wind, make sure you add caulk to the outside of the window. This will help improve the airtightness of the installation and keep any water, wind, and pests from getting through.
5. Ready to Plug it in
Your window air conditioner is ready for use. You must see to it that the power supply you intend to use is appropriately rated for the unit. Also, if you must use an extension cord, make sure that it’s appropriately rated.
A lot of factors play a significant role when purchasing a window air conditioner with heat. However, when you finally make a move to acquire window AC with heat, you’ll appreciate you made the right decision when you turn it on during a hot summer or cold winter day. We hope this window air conditioner guide has opened your eyes and instead of going for the regular window AC that only cool, you can shift to one with a heater so you can stay comfortable all year round.
