Central air conditioner units and ductless mini-split systems are the two most common options homeowners can choose for cooling their homes. Both of these two air conditioning systems have their pros and cons, which may depend on various factors. This short guide will help you make a decision which best suits your home.

Ductless Mini split system

This is a system which consists of an outdoor compressor unit and indoor cooling and control unit. These two are connected with bundled wiring. There are also multi-split systems with more than one indoor unit, one for each room, allowing the inhabitants to separately manage each indoor unit.

Ductless-Mini-Split-acMini split systems are expensive, but convenient and easy to install. These are good for concrete buildings, or old buildings with thick walls. Air conditioners are fully electronically controlled, which allows these to maintain the same temperature for prolonged periods and can have a postponed turning on and off with a timer.

Most split systems can use a reverse cycle in winter, which turns these into heaters. Some also have inverters, which allows their operation in extreme heat or frosts. Inverter mini-split systems are highly energy efficient and the best option for those who consider the heating function. Note that air conditioners are not among the most energy efficient ways of heating your home, due to high costs of power. However, it’s always good to have a source of heat which will supplement the existing oil or gas heating system.

Central air conditioning

central-air-conditionerCentral air conditioning system consists of a central air treatment unit from which the air is distributed to the rooms by fans via ducts. There are also collection ducts which recuperate warm air throughout the home and brings it back to the air treatment unit. Central AC systems are usually just meant for cooling.

Ducted central air conditioning systems are the best for people living in detached houses, and those who don’t want air conditioning systems to be visible on the facade or windows. Central air conditioning’s air treatment unit is usually located behind the home, on the ground, next to the rear wall.

These systems are cheaper to buy, but require additional ductworks, so installing the entire system has a greater cost than mounting a mini-split system which is ductless. The ductwork used by air conditioner unit is usually the same one used for heating.

SUMMARY

Mini Split systems: Quiet, compact, easy to install very precise, but expensive. Most suitable for people living in condos or small homes, and for those who require or want high level of comfort regarding temperature and noise. Also good to supplement the home’s heating system when it’s insufficient. Mini split systems can be installed quickly, but the outdoor unit will remain visible.

Central air conditioners: Convenient to use, highly energy efficient. The system needs duct installation. If you already have ducts of your heating system, central air conditioner may use it. These units can be noisy sometimes but are generally better for people living in larger homes who almost exclusively utilize this system for cooling.
