One thing you probably want to avoid during Toronto’s hot summers is ending up with a broken AC when its 40°C outside. To prevent a breakage, read on some common issues that you need to pay attention to:

  1. Thermostat problems — check to verify that your thermostat has been switched to the “cool” setting and that the temperature on the thermostat is below the temperature of the room it’s located in. Then check the unit’s sensor (it’s situated near the coil) and correct its position.
  2. Insufficient maintenance —you need to work on your AC unit periodically to keep it running smoothly. Essentially, you need to replace the filter when it gets dirty and clean the coils once in a while. These two simple chores will improve your system’s energy efficiency and prevent it from failing ahead of its time.
  3. Refrigerant leaks —you might have a leakage problem if the refrigerant is low. Refrigerant leaks not only cause issues with your A/C unit, but are also bad for the environment. Make sure to hire an HVAC technician to fix the leak and match up the refrigerant with the manufacturer’s specifications, this is not a DIY job.
  4. Electric control breakdown — if you have a system that’s oversized (which commonly occurs if the installation technician hasn’t done a proper job) the constant on and off switching can exhaust the compressor and fan controls. Your AC technician should check that as well as the electrical connections and contacts which can also present a problem due to corrosion.
  5. Drainage issues –Air conditioners can occasionally have drainage issues when it’s humid outside. On an exceptionally humid day you might want to check your condensate drain to make sure that it’s draining properly and that clogging hasn’t occurred.

If you follow these steps and take good care you’re your AC unit it will serve you for a long time and help save the environment by improving the energy efficiency of your system. Contact us for more expert advice on you AC problems.
