Factors Affecting Sizing


Air Conditioners come in different capacities ranging from 12,000 BTU’s (1 ton)- 60,000 BTU’s (5 tons). Determining what size of air conditioner your home needs is a crucial step in ensuring you receive the proper comfort in the house.  There are many more factors in the sizing than simply the square footage. These factors include orientation of the home, amount of windows and which way they face as well as shading of the home. Furthermore, the age of the home and insulation values can affect your sizing requirements greatly.


A bungalow of a certain square footage may require a different sized unit than a three-story home with the same square footage. Furthermore, the way you operate the unit, and your lifestyle can greatly affect which unit will deliver you the comfort you desire.


The furnace and ductwork distribution are another key item in the equation when determining the best sized unit for your home.  Though you may feel a 3.5-ton air conditioner is needed, if the furnace blower can not deliver the proper amount of airflow, you may find yourself dealing with issues down the road.


When evaluating the costs of a central air conditioner in Ottawa, the sizing and capacity will play a large part in the expected costs of an installation.



Installation Parameters


When you are having an air conditioner installed in your home, the factors surrounding the installation can vastly change the cost of the unit.  These factors can include the following:


  • Does the lineset connecting the indoor to outdoor unit run through finished spaces?
  • What is the length of the lineset?
  • Is there an accessible drain near the furnace or does the condensate water need to be pumped to another location?
  • What are the electrical requirements? Is the electrical panel accessible and is getting a wire from the panel to the outdoor condenser cumbersome?
  • Do ductwork modifications need to take place? Are there adequate return and supply airs in the home for the new system?
  • Are there any other items that need to be brought up to current code standards for the installation?
  • Is the unit going to be placed on brackets or a pad outside and what is required to make this happen?



The installation of an air conditioner is the most important day in the life of the unit. These machines are quite different than an appliance like a refrigerator or stove that can be plugged in and work well. The installation is paramount in the longevity of the unit and as such, these installation parameters can add or subtract costs on the installation.



Quality of Air Conditioners


Air Conditioner quality varies greatly and as a result units can range from $2500-$10,000+. There are four factors that generally define the quality of the unit.


Sound Levels– The sound levels of condenser generally correspond directly with quality of unit. An entry level AC may run 76-80 dB and can be quite loud. A mid range AC is generally operating between 69-74 dB and high end units may be as quiet as 56 dB (Whisper quiet!)


Compressor Operation– The compressor is the heart of the air conditioner. Entry level units generally have a single stage compressor, meaning they are either on or off.  Two stage compressors allow the unit to operate at two different speeds (providing varying levels of cooling and dehumidifying the home much better than a single stage). Finally, variable speed compressors can ramp up and down allowing for precise temperature control and unparalleled dehumidification.


Efficiency Levels-Air Conditioners are rated by using SEER (Seasonal Energy Efficiency ratio). Entry level units start at 13 SEER with high end models reaching up to 28 SEER! The higher the SEER the less electricity your unit will need to run.


Warranty– Some air conditioners come with 1 year parts warranty. Most reputable brands come with 10 year parts and 10 year compressor warranty. You can find units with 12 year parts and even lifetime unit replacement warranties!


In summation, Air Conditioner prices vary greatly in the Ottawa area. With our relatively short but hot summers, we tend to see clients spending $3000-$4500 on average for their air conditioners, with many people opting for 14-16 SEER units.
