Should I Invest in a Split System Air Conditioner?

When you are considering a home renovation project, one of the major purchases might be upgrading your heating and cooling system to a split system air conditioner. There are considerations when choosing such an expensive reno. You will want to consider the type of unit for your particular home and climate, the price of the unit, operating costs, potential savings and the intrusion of the unit.

What type of home do you have?

Is it a small condo or apartment, semi-detached or fully detached? The size of unit will need to reflect the total square footage, as well as how many outside walls you have. Do you live in a tropical climate, temperate, or one with wide variations in climate (-30C to +30C) , A split system air conditioner splits the hot side from the cold side within the unit, so both heating and cooling options are available.


The up-front price of the unit is only one consideration in the financial picture. Of course, the price of the unit depends on the size of unit for area required, as well as additional options (such as wide variable climate adaptation, remote control, zoning vs whole-house control, etc). Many local utility companies offer rebates or government grants periodically, which will help with the up-front cost. The ongoing maintenance cost should be much much lower than your existing method. Overall savings can be calculated after one full year of use – allowing for changes of seasons, humidity and other climate issues.


Like any other hardware in your home, there will be a visible unit for the split system air conditioner within the living space. Most have the appearance of a smooth white bulkhead with venting on the top. It mounts on the wall at a high level so it will be safe from small children. There may be a separate panel or remote control. There may be a neat cube-like unit outdoors. Specifics depend again on the type of model chosen and specific manufacturer. The noise produced is low, like a fan, and many people agree it becomes background “white noise” much like your fridge.

Manufacturers’ websites will often take you through a decision-making process to help identify the unit specific for your needs. Read from multiple quality sources, speak with your local HVAC installers (a home building supply store may identify some), and have an in-home assessment done by the manufacturer which are usually cost-free. All of these things will enable you to choose the best unit for your home, climate, needs and budget.
