Why Upgrade From A Window AC To A 1.5 Ton 5-Star Split System?

Window ACs are the old way of ensuring cooling and comfort, they are not very energy efficient or feature rich when compared to latest split AC models. This causes the electricity bills to rise high, a 5 star split air conditioner on the other hand even if comes at a high upfront cost helps with energy efficiency and reduces electricity bills.
Window ACs that are old eventually require more maintenance and servicing, leakage issues, noise interruption, inconsistent cooling are some of the major issues you start facing, replacing with a 1.5 ton 5 star split AC would solve all of this in one go.

Beyond Noise Levels: Assessing AC User Comfort Factors

When your air conditioner generates noise when functioning, that sure is a matter of proper discomfort, but that is not the only thing that contributes to comfort. Here are some factors that need to be considered for better user experience.

The capacity of an AC to cool a space quickly and ensure that the entire room gets comfortable impacts the comfort of the user directly.
For coastal areas where the humidity is high an AC that comes with a dehumidifier not only cools the space but also maintains the balance of moisture in air for better comfort.
The method of controlling the function of an air conditioner also needs to be simple and convenient, it should not be complex or confusing in any way as that will deter the experience of AC function and affect comfort.

Maintenance Difference In Window Vs Split AC

Window AC	Split AC
The aspect of cleaning the filter of a window AC is quite easy and simple, one can easily do it at home without much hassle.	Filter cleaning for a split AC is also quite simple, it is similar to that of a window AC and can be easily done at home.
Servicing of an AC in case it starts malfunctioning can be done easily and is not much of a complex issue since there is a single unit to handle.	With a split AC malfunctioning service needs to be done by professionals and depending on the damage may be costlier and more complex than that of a window AC.
Refrigerant leakage is not very common with window air conditioners.	The frequency of refrigerant leakage is more and also needs professional gas recharging.
