The size of your air conditioner unit is important, but so are efficiency and performance levels. Advanced HVAC in Ottawa can help you find the right size and configuration of air conditioner for your use and budgetary needs. One of our friendly & helpful A/C techs can visit your home or business, assess the size and layout of your home, look at the existing ductwork and (if you already have one) current A/C unit, then will advise on recommendations for a new air conditioner that will serve you and your home or office/store/etc. well. Square footage of the building is one unit of measurement we look at. But there’s also the total length of the ductwork that the air will be flowing through. Also, we take into account how many floors are in the home or space being cooled, as well as the sun and/or shade conditions outside, etc. All of these combine to give us a good idea of the size of air conditioner unit you need as well as how well it should perform.
