Spring Checklist: Things To Do Before Turning On Your Air Conditioner [13 steps]

 In Air Conditioning in Waterloo and Listowel

Spring has arrived in the Waterloo and Listowel Region! Before you know it, the hot, humid weather will be upon us and you’ll want to turn your air conditioner on. Before you turn your system on for the season, take a look at this spring checklist that our team put together for you. This list will walk you through the steps you need to take before turning on your air conditioner.

Spring A/C Checklist

  • Visually check your outside unit for any damage
  • Replace the filter in your furnace
    • Make sure you replace the filter with one that was designed for your duct system. Not doing this may cause your air conditioner coil to freeze and leak water through your furnace. If you are not sure what filter is right for you, contact your heating and cooling professional.
  • Replace the batteries in your thermostat
  • Make sure all your vents are open
  • Remove the cover on the outdoor unit
  • Visually check for any damage to insulation on the refrigerant lines going into your house from the outdoor unit to your furnace
  • Visually check for any damage or broken wires going to your outdoor unit
  • Pour about a ½ cup of chlorine bleach down your condensate drain and flush it with about four litres of water
  • Clear any shrubs, grass, and debris away from your outdoor air conditioner unit. This will ensure that you have sufficient airflow and will allow it to work efficiently
  • Turn your humidifier to the summer setting and put the damper in summer position
  • Set your air exchanger to the summer setting
  • After you start the air conditioning, monitor around your furnace regularly for a couple of days to ensure there are no condensate leaks
    • If you notice water around your furnace, shut off your air conditioner immediately, turn the electricity off to your furnace, and call a professional
    • Listen for any banging, screeching, or other unusual noises once your air conditioner is running
  • Call a professional to inspect the refrigerant, electrical, and duct system to prevent unnecessary breakdowns, repairs, or costly energy bills

Other Things to Consider

While our spring checklist was designed for the average DIYer, the following suggestions may require professional assistance:

  • Installing a less restrictive filter system designed for your ductwork. This will not only protect your equipment from dirt but it will also make the air in your home cleaner.
  • Getting a musty odour from your air conditioner? Add an ultraviolet light to your coil to prevent mould and bacteria.
  • Do you have pets that venture around your air conditioner unit? Consider that the urine from animals is extremely corrosive to the aluminum fins on your air conditioner. Try to identify if any corrosion has occurred because of urine.
  • If you haven’t disinfected your ductwork or furnace blower for a while, spring is a great time of year to have this work done.
  • If your air conditioner is old and you’re noticing that your energy bills are climbing each year, you’ll want to consider upgrading your HVAC system to one that’s newer and more energy-efficient.

Many of these considerations can be addressed with a semi-annual inspection in the spring and fall. If you need professional maintenance before turning on your air conditioner, let us know.
