Thinking about getting an air conditioner? Smart move—Ontario summers can be scorching. But figuring out the costs can be confusing. Let’s break it down so you know what to expect in 2025.
What Does a New Air Conditioner in Otario Cost in 2025?
The price of an air conditioner varies based on the type, size, and features. Here’s a quick overview:
While window and portable units are options for homeowners, we recommend and specialize in both ducted (Central A/C) and ductless (Mini-split) systems.
With that in mind, we’re going to focus on those two major types of air conditioners and what they cost in Ontario in 2025.
What Affects New Air Conditioner Prices?
Efficiency Ratings (SEER)
Air conditioners have efficiency ratings known as SEER (Seasonal Energy Efficiency Ratio). Higher SEER ratings mean better efficiency but come with a higher price tag. For instance:
- 14 SEER: Standard efficiency; more affordable upfront but higher operating costs.
- 16 SEER: Moderate efficiency; better energy savings for a slightly higher cost.
- 18 SEER and above: High efficiency; significant savings in energy costs over time.
System Size and Capacity
The size of your home determines the required capacity of the air conditioner, measured in tons. Larger homes need units with higher capacity, which increases the cost. For example:
- Small homes (<1,500 sq ft): Typically require 2-ton units, which cost less.
- Medium homes (1,500–2,500 sq ft): 3-ton units are common.
- Large homes (>2,500 sq ft): Often need 4–5 tons, which means a bigger price tag.
Installation Complexity
How easy or difficult it is to install your air conditioner matters.
Some things that can affect the total cost of the job include:
- Existing Ductwork: If your home already has ducts, installation is easier. Without ducts, you’ll need a ductless system, which can cost more depending on a few factors like the design of your home.
- Electrical Upgrades: Older homes might need electrical upgrades, which can add $500 to $2,000 to the total cost.
- Labour Costs: Labour typically costs $1,500 to $2,000, depending on how complicated the project is.
Additional Features
Modern air conditioners come with optional features that make them more comfortable and efficient but also raise the price:
- Variable-Speed Compressors: Adjust cooling power to match your home’s needs. These can cost between $1,000 to $2,000 more than standard models.
- Smart Thermostats: Let you control your system remotely. Adding one will cost ~$200 to $500.
- Noise Reduction: Premium systems run quieter, but they can add $500 to $1,000 to the total price.

When choosing an air conditioner, it’s essential to understand the difference between single-stage and two-stage systems:
- Single-Stage Air Conditioners: Operate at full capacity or not at all. They are less expensive upfront but can lead to higher energy bills due to less efficient operation.
- Two-Stage Air Conditioners: Have two operating modes—high and low. They run at a lower capacity most of the time, providing more consistent cooling, better humidity control, and improved energy efficiency. However, they come with a higher initial cost.
Example Scenarios for Air Conditioner Installations
Customers often ask us to give them a ballpark figure and this is really hard to do because every home is different. But, if you want to wrap your head around all this and set some early expectations, here are a couple of scenarios to help you.
Scenario 1: Central Air Conditioner for a Medium-Sized Home
- Home Size: 2,000 sq.ft with existing ductwork.
- System: 3-ton central air conditioner with 16 SEER efficiency.
- Add-Ons:
- Smart thermostat: $300
- Permits: $200
- Total Cost: $4,500 (base system) + $300 (thermostat) + $200 (permits) = $5,000
Scenario 2: Ductless Mini-Split for a Home Without Ducts
- Home Size: 1,500 sq.ft without ductwork.
- System: 2-zone ductless mini-split system with 18 SEER efficiency.
- Add-Ons:
- Electrical upgrade: $1,000
- Permits: $200
- Total Cost: $5,500 (base system) + $1,000 (electrical) + $200 (permits) = $6,700
Considering a Heat Pump Instead?
If you’re shopping for an air conditioner, you might also want to consider the alternative: a heat pump. Heat pumps can both cool your home in the summer and heat it in the winter. This means you can replace your air conditioner entirely while leaving your furnace as just a backup system in the winter.
