how to choose a central air conditioner

When it comes time to replace your home’s air conditioning system, it can be challenging to know which unit best fits your needs. Many different makes and models are available on the market, each with its own set of features and benefits. But, do you have any idea how to choose a central air conditioner?

This blog post will discuss choosing the suitable central AC for your home. We will cover everything from sizing to budgeting to energy efficiency so that you can make an informed decision about which unit is right for you!

Type of Central Air Conditioner You Want

It’s advisable to choose one of Canada’s three most frequent kinds of central air conditioners. Price points and energy efficiency are the most noticeable distinctions between each model.

Dual-Stage Condensers

Consider a dual-stage air conditioner if you need two modes of operation. Dual-stage air conditioners operate at a lower or higher temperature depending on the weather. These settings allow your air conditioner to work more effectively than a single-stage unit while still costing less than a variable-speed model.

If you want to switch to a dual-stage condenser, ensure that the interior furnace or air handler, thermostat, and evaporator coil are all compatible.

Single-Stage Condensers

The most common central air conditioner in Canada is the single-stage condenser. If you have a smaller home or budget, this model may be the best option.

Single-stage units are less expensive than their dual-stage and variable-speed counterparts, but they only operate at one speed: full blast. It means that they are not as energy-efficient as the other two types of air conditioners.

Variable-Speed Condensers

A variable-speed condenser is the most energy-efficient type of central air conditioner. These units can adjust their cooling output based on the temperature outside. It means that they use less energy to cool your home, saving you money on your energy bill.

If you are looking for an air conditioner that is both energy-efficient and quiet, a variable-speed condenser is a way to go.

Size of Central Air Conditioner You Need

The size of the central air conditioner required for your home depends on a few factors. You need to consider the size of your home, the number of windows, the insulation, and more.

Even houses with similar floor designs and construction materials might have drastically different cooling requirements. For instance, neighbouring trees may provide more shade to one home but not the other, resulting in one house is naturally cooler than the other.

These variables may make or break the efficiency of your AC and the unit size you pick.

You’ll need to measure the cooling capacity of an air conditioner in tons. You may obtain a general approximation of the AC unit size you’ll need by comparing the square footage of your house to the cooling capability of the AC unit.

Budget for Central Air Conditioner

You may determine the cost of a central air conditioner by its size, type, and features. Single-stage units are the most affordable, while variable-speed condensers are the most expensive.

When budgeting for your new air conditioner, be sure to factor in the installation cost. Installation costs can vary depending on the complexity of the job and the type of unit you choose.

Energy Efficiency of Central Air Conditioners

Measure the energy efficiency of a central air conditioner by its seasonal energy-efficiency ratio (SEER). The higher the SEER rating, the more efficient the unit is.

You can find the SEER rating on the yellow EnergyGuide label. The SEER rating will be listed as a number between 13 and 23.

Remember that a higher SEER rating doesn’t necessarily mean that a unit is better. Units with a SEER of 23 may not be available in your area because they are not required to meet minimum efficiency standards.

The SEER rating is a good way to compare the energy efficiency of different models, but it’s not the only factor you should consider when choosing an air conditioner. The size, type, and features of a unit play a role in its overall efficiency. The higher the SEER rating, the more efficient the unit is.


When choosing a central air conditioner for your home, you need to consider the size of the unit, the type of unit, your budget, and the unit’s energy efficiency. Single-stage units are the most affordable, while variable-speed condensers are the most expensive. The size of the system you need depends on the square footage of your house.

Moreover, ensure to factor in installation cost when budgeting for your new air conditioner. The higher the SEER rating, the more efficient the unit is. Finally, make sure that the system you choose is available in your area.
