Best Window Air Conditioners in India: Buying Guide
Factors to Consider When Buying Flour Mill for Home Use
If you want the best value for your money when buying the best flour mill for home use, you should ensure that it has the following features.
Size & Tonnage
A 1.5-ton window air conditioner is an excellent option for a 120-190 sq. ft room. However, if your room is smaller than this and you don’t want to spend money on a small A.C. unit for such a small area, consider an A.C. with several cooling modes like rapid cooling or turbo. If your space exceeds 190 square feet and up to 270 square feet in size, you’ll need a 2-ton window air conditioner to cool it properly.
Another important factor to consider when it comes to size is the unit’s physical dimensions. You’ll need to ensure that the air conditioner you select will fit in the window of your choice, so be sure to measure the window before making your purchase.
BTU (British Thermal Unit)
The BTU number of an air conditioner indicates how much heat the A.C. can remove from a room per hour. So, the higher the BTU, the more powerful the A.C. unit is. For example, a 1.5-ton window A.C. with a 10,000 BTU rating can remove 150 cubic feet of heat from your room per hour, whereas a 2-ton window A.C. with double the BTU (20,000) can remove 300 cubic feet of heat in that same amount of time. In short, choosing an A.C. unit with a higher BTU will result in faster cooling. Reduce A.C. capacity by 10% if your home is heavily shaded. Increase A.C. capacity by 10% if your home is sunny. Then, for each additional person who usually resides in the space, add 600 BTUs.
In other words, it is more efficient to use an 8,000 BTU unit that runs 75% of the time during hot weather than a 12,000 BTU unit that runs 50% of the time.
EER (Energy Efficiency Ratio)
The EER is a rating that indicates how much energy an air conditioner uses to produce one BTU of cooling. So, the higher the EER, the more energy-efficient the A.C. unit is. For example, a window air conditioner with a 10 EER would use 1,000 watts of power to generate 10,000 BTUs of cooling, whereas a 20 EER unit would only require 500 watts to do the same. In short, choosing an A.C. unit with a higher EER will result in lower energy bills.
The star rating of an air conditioner measures how energy efficient it is. The higher the star rating, the more energy-efficient the A.C. unit is. A 5-star window A.C. unit uses 20% less energy than a 4-star unit and 40% less energy than a 3-star unit. In short, choosing an A.C. unit with a higher star rating will result in lower energy bills.
An air conditioner’s noise level (measured in decibels) indicates how loud it is. Therefore, the lower the noise level, the quieter the A.C. unit is. A window air conditioner typically has a noise level between 40 and 50 dB.
If you’re looking for a quiet air conditioner, check the noise level before purchasing. The decibel rating will be listed in the product specs.
Of course, you’ll also want to consider the cost of the A.C. unit before making your purchase. Window air conditioners range in price from INR 25,000 to INR 40,000. The size, features, BTU rating, and EER rating all play a role in determining the cost of the unit. So choose the A.C. unit that best fits your needs and budget.
Inverter Or Non-Inverter
Inverter A.C. helps save electricity by 30-40% if you continuously run it for more than 2-3 hours, and inverter ac is comparatively more expensive than non-inverter A.C.s.
Therefore, if your usage is less than 3 hours daily, you may go for a non-inverter A.C.
For example, if you use a 1.5-ton inverter A.C. for 5 hours daily, your total cost is reduced by more than ₹4000 each year compared to a non-inverter version.
Inverter ac is quiet and has a lower noise level when compared to non-inverter A.C.s. When an inverter ac is turned on, it doesn’t make that irritating sound that a non-inverter A.C. makes.
Warranty and Service
Most window air conditioners come with a one-year to two-year warranty, so double-check the service and replacement terms before buying. Choose a company with a nationwide service network so that you may easily get help if required.
If a unit is installed correctly, it can improve cooling and save energy. As a result, if you install a 1.5-ton unit for a 180 sq. ft. room exposed to direct sunlight, its efficiency will fall by 30-35%, resulting in higher electricity bills. Choose an appropriate installation site and engage the services of a competent and experienced technician.
Advantages of Window A.Cs over Split A.Cs
- Window air conditioners are less expensive than split air conditioners and suitable for budget-minded consumers.
- Window air conditioners are also easier to install than split air conditioners. They can be installed in just a few minutes, whereas split air conditioners require professional installation.
- Window air conditioners are also more compact than split air conditioners, so they take up less space and can be used in small rooms or apartments.
- Window air conditioners require less maintenance than split air conditioners. Since there is only one unit, there are fewer parts that can break down or require repair.
Disadvantages of Windows Air Conditioner
- Windows air conditioners can be very loud, making it challenging to enjoy peace in your home.
- Because they are installed in your window, they can block out natural light and make your room feel more closed off.
- Windows air conditioners are less energy-efficient in larger homes because they only cool the installed room. This means you will have to run several units to cool your entire home, which can be very costly.
- They can also be a security risk since they must be installed in an opening in your home. If not installed properly, they can easily fall out of the window, which could cause serious injury.
Tips to Maintain your Window Air Conditioners
Regular cleaning and maintenance of your window ac are essential as it helps in better cooling and performing under good condition while making it last longer. While there are so many cleaning and maintenance tips, there are different things that should be considered for window air conditioners, especially in those summer months after use.
Here are some tips to follow:
Note: The mandate step is to unplug it whenever you perform any cleaning.
Filters are the most important part of any air conditioning unit. Filter helps you provide fresh air with proper airflow by eliminating dust particles. If it is not cleaned properly, it results in blockage or clogged filters, which will not be good for better flow. Generally, replacing a filter in 1 to 3 months is recommended. Some are permanent, so they do require cleaning. Just brush, and they are clear. If required, wash them with soap and dry them after you can reuse them. Whereas some need replacements means you must replace them in a certain period. It is always better to seek professional help while replacing filters.
Condenser Coils and Evaporator
If a filter is dirty and blocking the air and filled with dirt and other harmful contaminants. In that case, it can impact the air quality and degrade the condenser coil quality and evaporator.
Regular cleaning and coil maintenance will help you alleviate the performance. It is recommended to clean the coil every year.
- Vacuum the coil using brushes.
- Remove the coils.
- Place it outside.
- Rinse the coils
- Rinse off the cleaner and let it dry.
Inspect Coils and Clean them
The outside coil may get dirty from harmful particles and contaminants, which will also impact the unit’s performance. It is essential to check them regularly, and if they get dirty, you can blow air or clean them by using cleaning material with a soft brush. If the coil gets entangled, make sure to strengthen them by using a fin comb.
Clean the Water Pan
It is essential to clean the water pan as it may lead to mildew or mold growth. You can use warm water, soap, or vinegar to clean the base of the pan.
If it is not possible to check the issues regularly or in a timely manner, it is essential to look for professional advice. Schedule your services with the best technician to check for leaks, airflow, and coils, which will impact the air conditioner’s performance.
Window air conditioner maintenance is essential to work this in a proper condition. With these points in mind, you can take care of the window air conditioning units.
