Here are some key things to consider:

  • Home Size and Location:
    The amount of sun (heat) your home receives, the direction it faces and the size of the space you wish to cool are key when evaluating the best air conditioning system to keep your home cool.
  • Insulation/Air Tightness:
    The height of ceilings, the thickness of windows and the materials that make up the wall assembly, play a significant role in keeping the cold in and the heat out during hot Ottawa summers. These and other structural details will be determining factors when choosing the size and power of the AC unit that’s best for your home.
  • Energy Efficiency:
    Energy consumption and costs are important considerations when choosing the right AC unit. Checking the energy efficiency of an air conditioning system (SEER) is important when evaluating the best system for your home. The higher the SEER rating, the less energy the unit needs to reach and maintain your ideal temperature and the lower your energy costs will be.

There are other factors to consider before making the final decision when renting or buying an AC system. Call today, we’re here to help you find the air conditioner that’s right for your home and budget.

  • What does SEER mean and why should I pay attention to these ratings?
    The Seasonal Energy Efficiency Ratio (SEER) measures the cooling and heat pump efficiency of your air conditioning unit. Ratings range from 13-21. The higher the SEER rating, the more efficient the AC unit.
  • How often should my AC get maintenance or a tune-up?
    Keeping your air conditioner working at its best for a longer period requires regular maintenance and the occasional tune-up.
