Factors to Consider When Buying the Best Ductless Air Conditioner

The Price

A ductless air conditioner has a higher price tag than the traditional ones, but it is still more economical in the long run as you save money on electricity costs. If you have a large room, or if you want to have a heat pump as well, be prepared to spend more.

Aside from the upfront cost, you should also consider the installation and ongoing energy costs. Most ductless air conditioners are easy to install because you no longer have to worry about running ductwork like a central air conditioning system does. However, there are times that you need to hire an HVAC specialist to get the job done especially if installing the unit yourself will void the warranty.

Energy Efficiency

If you want to know how efficient an air conditioner is at saving energy, check out the SEER rating. The higher the number is, the better the unit will perform with regards to overall energy use.

BTU Requirements

Power in air conditioning is measured by BTUs, the higher the number, the more space an air conditioner will be able to cool or heat effectively. If you live in an area that experiences intense hot summers, then choose an air conditioner that has a high BTU of 18,000 or more.

You may also need to measure the size of your room to get the right BTU for the air conditioning unit you will put in it.

Quality

A ductless air conditioner is a big investment, and as such, you need to make sure that what you are buying will last you a long time. Some units come with warranties, so it is a good idea to check these out. Also, we highly recommend checking out online reviews of the product you want to buy. This way, you can have information from those who have actually bought the product and give useful feedback.


Ductless air conditioners are becoming more popular because they are proven to be energy efficient and cost-effective. You can have the cooling comfort in your home without spending so much money on electric bills. When you have figured out the money you want to spend, the features you want to have, or if you already have a model in mind, this guide will help you decide what the best ductless air conditioner for your home.
