The Cost of Air Conditioning Systems

Last modified: 2022-05-10 | Approximate reading time 6 mins

When temperatures reach new heights, it is normal to want to stay cool. The easiest way to do this is of course to opt for an air conditioner. So what options are available on the market?

Types of air conditioner systems

There are several types of air conditioners that can easily be installed at home. It is recommended that you choose the power of your air conditioning system (which is calculated in BTU) according to the surface area of your living space. In order to provide you with an exact approximation, we will compare 3 air conditioning units, each designed to cover an area of 450 sq. ft. (41sq.m.) for a cooling capacity of 10,000 BTUs.

Window-mounted air conditioner

Individually, a window-mounted air conditioner costs an average of $400, with a price variation depending on the product range that you choose. This is the ideal solution for a tenant but the system must be removed during the winter and then re-installed every spring and it also remains a fairly noisy option. 

Mobile air conditioning unit

Another option is the mobile air conditioning unit which costs an average amount of $480 for a 3 in 1 system (air conditioner, fan and dehumidifier), this type of system can easily be moved from one room to another.

Wall-mounted air conditioner

The wall-mounted air conditioner is much more expensive than the window-mounted air conditioner, costing between $600 and $1200, for a unit that operated via remote control. It should be noted that the last two options make considerably less noise than a window-mounted unit and will not need to be re-installed each spring.

It is highly recommended that you invest in Energy Star certified air conditioners that guarantee high energy efficiency and energy savings. This kind of product helps reduce your electricity bills, as well as your carbon footprint.

Prices for central air conditioning systems

The other remaining options for keeping your home cool are central air conditioning systems. This alternative is recommended for homes with greater square footage that cannot be effectively cooled by window, wall, or mobile air conditioning units. In terms of energy savings, this option is more efficient but is also much more expensive to buy. 

The bi-block air conditioner sells for roughly $3000 while a central system costs around $4800. The heat pump will cost at least $4800 while the ceiling air conditioning system installed in the attic will be approximately $7800.

The dual-block air conditioner offers air conditioning in the top part of the walls using nozzles to disperse the cooled air. As for the central air conditioner, it allows fresh air to be projected into the same ventilation ducts as the heated air.

The heat pump offers both heating in the winter and fresh air in the summer but it is cumbersome and some models are very noisy, not to mention expensive. Therefore, it is absolutely essential to compare different options thoroughly.

Finally, the ceiling air conditioner is a solution that applies only when the house does not have a forced-air duct system. This system is installed within the roof and pushes air through ventilation slots.

The factors that will cause air conditioning system prices to vary

First, it is important to take into account that each quote will be different and that several factors can influence the price of installing an air conditioning system in your home.

Of these factors, the number of air conditioning units you have installed will have a significant impact on the costs of installation. Regular mono-split air conditioning systems require two units; one on the inside and one on the outside of your home to generate cool air. Multi-split units require a single outdoor component and several inlets within your home to refresh as much desired space as possible.

Obviously, a mobile air conditioning system will require a single interior unit since it is installed within the home and can be moved around freely. Several other factors should be considered, such as the quality of your air conditioner's motor and the power output of each unit as you use it.

Technological options and accessories, the location of the installation and the addition of a heating option can also contribute to increases in the price of an air conditioning system, potentially adding at least 15-20% to the final invoice.


Generally speaking, if you hire a contractor that specializes in air conditioning they will charge you around $60 per hour. On the other hand, it is very rare that a contractor will agree to install a unit that you have previously purchased from another company or over the internet. When you hire a professional contractor for this job, it is also important to keep several things in mind to ensure that they are well tasked for the job.

Before you’re ready for your quote, they should ask you several questions related to your needs for an air conditioning unit (as well as heating in the case of a reversible air conditioning system) since each job is different and prices could vary from one contractor to another.

Knowing that contactors often offer ''package deals'', it's necessary to check out prices. If the prices are too low then you should be wary and if they’re too high then it is simply too expensive. The best solution is often in the middle and will fit within your allocated budget.

Subsidies to finance your air conditioning system

It is true that the installation of a new air conditioning system can represent a significant investment. For this reason, various programs have been put in place to help you finance your air conditioning project.

Renoclimat Program: The  Renoclimat grant encourages work aimed at reducing the energy consumption of a home while improving its comfort. Financing prices differ depending on the improvements you are looking to make to your home (insulation, waterproofing, etc.).

You will find on this page of Energy Transition Quebec the details of the financial aid proposed according to the work you wish to do.

Warranties and quality

If you decide to buy your air conditioning system and install it by yourself, know that it is easy to get an idea of the system’s quality based on the warranty that is offered. Generally, the best quality products come with warranties that cover for anywhere between 5 and 10 years.

Also worth noting is the fact that when selecting your air conditioner, it is quite important to consider the number of BTUs you will need to make sure your home is effectively cooled. This aspect ensures your home’s temperature will be controlled optimally. It is also worth checking the SEER rating of the product to save on your energy costs and the level of decibels emitted by the unit. 

When to buy or change your air conditioning system?

As you can imagine, it is recommended that you change your air conditioning system outside of the summer period because air conditioning professionals are all very busy at that time of the year. If you decide to buy or replace your air conditioning system, you should do it in the fall or spring, as it will be easier for you to meet with someone. In addition, you will have access to a lot more choices between different models of air conditioning systems available on the market.

The other reason not to complete this work during the summer is prices. In fact, appliance and installation prices can increase by $200 to $600 and even beyond. In addition, the more complex the installation, the more expensive the process will be.
