Prevent AC Breakdown by just looking, listening and cleaning

You can help prevent your air conditioning from breaking down and reduce repairs with some very simple, basic tasks you can easily undertake with your cooling system.

It should be noted we do not recommend taking anything apart or sticking your hand in it unless you are qualified. Leave that stuff up to the professionals.

Steps You Can Take

  • Cleanliness is the #1 problem. Keep it clean!
     Inspect your AC for dust, dirt and tree fluff build up
     Ensure furnace air filters, AC condenser (outside), AC evaporator (inside on top of furnace), secondary heat exchanger of furnace and dirty motors are kept clean
  • Listen for unusual noises, bearing squealing / grinding noise or vibration
  • Look at motors and see if oil is leaking out of them. Most new motors are non grease-able and if they are leaking its just a matter of time before seize up
  • Inspect for water leaks. High-efficient furnaces produce water and if water is present anywhere other than the drain, you need to get it to stop. Water can leak from the AC evaporator coil into the furnace causing damage

The above steps are a quick way to monitor any potential problems that may need to be addressed.

HVAC Maintenance

It is recommended by most HVAC equipment manufacturers to have your system maintained annually for safety, to prevent breakdown and in some cases to keep your warranty valid (see owners manual).

In addition to the inspection tasks (listed above) Airdrie Air’s furnace and AC tune ups will prevent future issues or break downs. The tests below should be performed by professionals.

We Provide the Following Tests and Inspections

  • Spin tests of motors. With the power off the inducer motor, blower wheel, condenser fan blade should spin and keep going freely. When we spin it and it stops quickly the bearings are seizing up. (Usually followed by over amperage number 6 below)
  • Check amperages to see if there are in proper safe range
  • Check capacitors / microfarads to see if there are in proper safe range
  • Check voltage to see if it’s in proper safe range when not running and running
  • Checking gas pressure and setting up properly for 3600 feet above sea level. (Airdrie is 3602 feet)
  • Checking safety limits and pressure switches
  • Check AC refrigerant levels, superheat, sub cooling, temperature differences (TD) and check air flow (400 CFM per ton of cooling)
  • Check circuit boards and contact points for burn marks, pitted contacts or resistance through relays
  • Check drain lines for proper flow and no blockages
  • Check ignitor for visible wear/breakdown of material, whiteness spots and check for high Ohm readings
  • Check flame sensor for corrosion build up and low flame signal readings - then clean
  • Pull and Clean furnace P traps on high-efficient furnaces
  • If you’re on an acreage and you have a high-efficient furnace or boiler you should always have a condensate neutralizer kit to protect your septic tank concrete walls from breaking down
  • Checking static pressures on supply and return air ductwork and let you know if you have an air flow issue which will affect your temperature and comfortability throughout your house
  • Checking Carbon monoxide levels from flue pipes and your homes air you breath

We will present 3 options if we find an issue with your system. – leave it, fix it or replace it.
