We can already feel the mercury dropping, especially at nighttime, as we are back in schools and companies are planning to call people back in offices from the long work from home culture. No matter how long the transition takes, it is always better to be prepared and give your employees, students, customers & other civilians the best comfort conditions and your HVAC system plays an important role in this.

Since Canada is known for its crazy weather, there might be a weekend coming very soon where we realize we need heat from the hibernating Air handling units, boilers, heat pumps, roof top units or furnaces and the system is just not ready. This is without a doubt the best time to schedule the winter – prep HVAC maintenance.

It is always better to be proactive than reactive when it comes to the harsh winter weather. Also, considering the global supply chain crisis, every industry is scrambling to get the required parts and raw materials for their projects, the lead times can vary a lot when the need is urgent. Commercial and industrial HVAC industry is no different to this squeeze in supply of HVAC equipment.

Importance of Winter Maintenance for your HVAC system

The annual tune ups and calibration of your HVAC system is the most important thing in your “to-do” list in order to avoid any untoward situations later on.

The benefits are as follows:

  • Life of the HVAC equipment or Heater. All manufacturers consider the scheduled recommended preventive maintenance services into account when forecasting the life of the Heater, VRF, chillers, boilers or any other equipment which provides comfortable conditions for a facility. The heater is unlikely to make it that far without maintenance. You get the longest possible effective life for your heater with regular care.
  • Avoid warranty being void. Sometimes it might just be the unfortunate factory or manufacturing defect and a major costly part of the equipment can fail. When you apply for warranty claims you need to provide the manufacturer reports of timely maintenance of the equipment in order to get the parts replaced.
  • Maximum energy-efficiency. The regular tune ups of the HVAC system ensure the units are running at maximum efficiencies and thus reaching designed temperatures in minimum amount of time. This will bring down the operating costs to minimum and ensure longer life of the equipment as well.  
  • Fewer repair calls. Being proactive with the scheduled maintenance most of the time results in fewer breakdowns and thus fewer repair calls.
  • Safer operation. Now that you have made the right choice of getting the equipment tested for pre winter maintenance, this ensures the chances for any major catastrophic event goes down and it is safer to operate.

Across food and Medical industry Small refrigeration units are very popular and important. If unit is breakdown in an unexpected time, then you have to face profit loss along with the repair cost. Mostly the reason for failure is lack of proper maintenance.

To achieve the reliable and uninterrupted operation follow the following tips

  1. Before starting the refrigeration unit make sure that the crankcase heater be energized at least eight hours minimize refrigerant migration foaming of the oils and the resulting immediate compressor failure.
  2. Manually check out and calibrate the basic parts such as safety controls and expansion values
  3. All electrical and mechanical equipment’s should be checked visually for any damages and wear outs.
  4. Measure the oil levels in the unit and check out the quality. If oil is low in level or damaged in quality replace with new oil.
  5. Check the motor magnetic starter and ensure the safe starting the unit
  6. Visually inspect all electrical terminals and ensure it was on proper tight.
  7. Examine the over load protection on the unit
  8. Check and clean the condenser from dirt and dusts.
  9. Check the system for the presence of moisture, if so install the filter dryers
  10. Take preventive actions to avoid moisture

Heating Systems Preventive Maintenance Checklists

It does not matter what type of heating is installed – it is important, what is being done to keep the system in optimal working condition. Timely preventive maintenance of heating systems – is the best way to ensure trouble-free operation and maximum performance. A maintenance before cooling and heating season also very important, it will avoid future failure of the system and keep the optimum temperature at the time when it is most needed.

 Gas Furnace Preventive maintenance Checklist

  1. Visually check for black Soot for chiefly composed of carbon, produced by incomplete combustion, if so contact Air Track Inc.
  2. Remove the combustion chamber and inspect the color of flames, the flames should be fairly even and blue. Yellow flames indicate dirty burners.
  3. turn the thermostat off and flip the power switch off on the heater
  4. Remove and clean the burners. Dirty burners can cause poor combustion
  5. Inspect the blowers and clean
  6. Change the heater filter every one to three months
  7. Check the heat exchanges for crack and damages
  8. Inspect the fuel pipe for corrosion and damages
  9. Check controls of the system to ensure proper and safe operation.
  10. Check starting cycle of the equipment to assure the system starts, operates and turns right.

Oil Heater Preventive Maintenance Checklist

  1. Look for signs of black soot around your heater. Soot outside the furnace itself could mean that the unit is burning more than oil
  2. Look at the smoke color, if the smoke is black the oil is not burn completely
  3. Carefully check for any vibrations and unwanted noise, if notice contact Air Track Inc.
  4. Check the fan belt
  5. Lubricate the blower motor fittings
  6. clean the burner nozzle prevents clogs and ensures that oil can easy move
  7. Check controls of the system to ensure proper and safe operation.
  8. Check starting cycle of the equipment to assure the system starts, operates and turns right.
