Frequently Asked Questions

Q. Is higher BTU better for air conditioners?

A higher BTU generally means that the air conditioner will be able to cool down larger spaces in a shorter time. Generally 8000-10000 BTU is recommended for small rooms. 12,000-18,000 or more BTU capacity air conditioners are better choices for larger rooms and offices, especially hallways and living spaces. You can select one depending on the size of the room or how fast you want the room to be cooled. Avoid buying air conditioners with higher BTU for small spaces as it will cost you a lot of unnecessary expenses which can be saved.  Also remember that higher BTU means more energy use and higher electric bills.

Q. Is Smart Control necessary to have in air conditioners?

Smart Control is a special feature that allows you to operate the air conditioner easily from your mobile phone or devices like Alexa and Google Home. It is not an absolute requirement to have smart control as it’s more about user experience than efficiency. If you want to have a low budget air conditioner and don’t require fancy features then you can opt for a normal air conditioner that doesn’t have WiFi features. However, if you already have multiple appliances with smart control that you actively use, then you might want to get a smart air conditioner as well.

Q. Is it necessary to buy an expensive air conditioner?

It is not always necessary to buy expensive air conditioners just because of their price. Oftentimes moderately priced air conditioners tend to have similar features to expensive ones but go unnoticed because people think the low price tag doesn’t guarantee good quality. While it is not advisable to purchase cheap air conditioners, you can easily opt for reasonably priced ones that come from trusted brands and have good user reviews. Remember that higher BTU costs more so if you have large rooms, be prepared to spend a few more bucks for best results.

Conclusion

Air conditioners are amazing devices that will help you have some comfortable summers without worrying about heat and sweat. When you decide to buy an air conditioner,  make sure you list down your requirements to check if the model meets them. It is also important to have a budget so that you don’t overspend on an appliance that could have been bought with a lower price. Make sure you thoroughly check the specifications of the model and compare user reviews to make the best pick.
