Ultimate Buyers Guide
A must-read before you pay for your new minisplit system
What is ductless split system?
A split system consists of two parts – an outdoor compressor and one or more than one indoor air outlet units.
"Ductless" means that the air conditioners rely on a set of pipes instead of ducts to connect the outdoor compressor to the inside unit.
Besides keeping your home warm in the winter and cool in the summer, it also provides protection from allergens and pollutants year round.
What is BTU?
BTU stands for the British Thermal Unit. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
Here is an approximate sizing guide:
250 square feet = 6000 BTU
350 square feet = 9,000 BTU
500 square feet = 12,000 BTU
750 square feet = 18,000 BTU
1000 square feet = 24,000 BTU
1250 square feet = 30,000 BTU
1500 square feet = 36,000 BTU
* Some Asian countries use 匹 instead of BTU. 1 匹 is arund 8000 BTU
Why it can save money?
Ductless cooling and heating systems can save 30-40 % off the energy costs of a forced air system. They are the go-to choice for newly constructed houses and additions, as well as those houses with no existing ductwork and which rely upon radiator or electric baseboard heating.
Zone-based Cooling and Heating Split-ductless systems can use up to eight separate indoor air-handling units for each outdoor unit. In this way, you can have eight separate rooms or zones, each with its own controller. You can save a lot of money by sending less heat into lesser-used areas of your home. For larger homes, you might consider purchasing two ductless multi-room outdoor units in order to boost your indoor cooling and heating to the entire house. The extra costs will be more than compensated for through eventual energy savings.
Do I need a 220 volt outlet ?
All multi-zone AC systems require 220V. For single zone units, while some brands do have less powerful models designed for 110V, we highly recommand that you check if it possible to have 220V at your place. If yes, ask the technicians to wire a 220V wire circuit for AC system exclusively.
How to install?
Do not install the AC system by yourself if you are not a certified technician. Simply buy from a store that will deliver the units to your place as well as intall everything for you, including wiring a new 220V power. The certified technicians are well-trained and happy to answer your question.
Where to buy?
We highly recommand that you buy from a local store, even if they charge a little bit more than the lowest price you find on Google. Call them first and ask if they can send a technician to your place to do a complimentary estimate. Then ask them to assist you with the paperworks such as 0% interest finance, move in/out insurance, rebates from ConEd if there is a promotion etc.
How to repair?
If you buy from a local store, contact them first. Usually they provide one year warranty with no charge. Minor issues such as parts replacement, not cooling, fan noise, water leaking etc. can be solved within a day by any local centified technician. Do not repair by yourself!
