Daikin Inverter Technology

Daikin offers their heating and cooling systems with Inverter Technology? What does that mean? Inverter (variable speed) HVAC systems are an energy saving technology that helps to reduce wasted operation in HVAC systems. Temperature is adjusted by changing the motor speed rather than turning the motor on then turning it off. Your comfort is maintained and your system operates at an energy conserving level. A simple analogy is comparing how your car performs in stop and go traffic versus cruising at highway speed making small adjustments to road conditions. Inverter technology allows your furnace to cruise along efficiently. Temperature is adjusted by changing motor speed and maintaining your comfort while operating at an energy conserving level. Inverter technology not only saves you money on your energy bills but helps prevent temperature swings in your home. You will feel the difference. Daikin inverter systems are also engineered to achieve lower operating sound levels. Finally the increased efficiency of the inverter technology system will reduce wear and tear on your HVAC system and therefore contributes to longevity and durability.

Continuous Fan Operation

Definite advantages can be obtained by providing continuous fan operation, particularly with the use of Fresh-Air Ventilation Systems, Energy Efficient Air Cleaners and Power Humidifiers. Today’s new and efficient motors can save you hundreds of dollars while providing better indoor air quality. Keeping your furnace fan running in the summer months can enhance home comfort, by circulating the air in your home. You’ll feel cooler and more comfortable.

Air Conditioner Maintenance

  1. After turning the power off to the unit, rinse outdoor coil annually with a garden hose to remove dust, grass cuttings, etc.
  2. Check unit operation annually. Do not wait until you need cool air! Annual maintenance is recommended.


  1. It is recommended that the thermostat be set no lower than 21ºC (70ºF) for cooling. Below this temperature, ice could form on the indoor coil, possibly resulting in damage to the equipment.
  2. If ice forms on the connectors going into the indoor coil or outdoor unit, turn the equipment off and call for service immediately!
  3. In cooling mode, do not lower temperature setting on the thermostat unless the outdoor unit has been off for five minutes. The breaker will probably trip or a fuse may blow if you turn it on too soon.

Eliminating Hot or Cold Spots at Home

The most common solution is to run the furnace fan on a continuous basis. A furnace with a variable ECM motor is the best choice for this.

You can also work on adjusting the registers or diffusers in the home. Start with restricting the flow through the registers in the rooms which are warmer than the others.

Does the Air Conditioner Sit on a Pad or a Bracket?

It really depends on the location of the condenser unit.

It is preferable to mount the unit on brackets attached to the foundation. This will eliminate any strain on the line sets due to movement of the ground around the foundation.  Call us to discuss if this option is right for your installation.

Noise Levels of Our Air Conditioner Units

The outside noise that comes from the condenser is 64 to 74 decibels (dB).

A hair dryer at three meters is 80 dB. The interior noise of the average car at 100km is 70 dB.

Our equipment suppliers offer the quietest air conditioner units available. Call us to discuss different units that are available.

I Have Two Furnaces, Do I Need Two Air Conditioner Units?

Tell us where the comfort issue is and at what time. Is it during dinner? At bedtime? If it is at bedtime and all the bedrooms are upstairs – it really might be possible to provide cooling only to that floor.

Troubleshooting Your Furnace or Air Conditioner

Please check the following before calling us for service. These are problems that homeowners tend to overlook and are not covered by warranty.

Step 1: Is your thermostat set to the correct function?

Step 2: Has the power to the furnace been shut off?

  • Electrical panel breaker
  • Power switch located close to furnace of high in the basement stairwell
  • Ensure the furnace fan door is on properly

Step 3: Is the filter clean? A dirty filter will eventually cause service problems and drastically decrease efficiency of both the furnace and air conditioner.

Step 4: High-efficiency furnaces have a System 636 PVC vent pipe which terminates on the side of home or through the roof. Ensure this is not blocked by debris, snow or ice.

If you cannot locate the problem by following these steps and require service, take note of the furnace model and serial number and call us.

Thermostat Maintenance

Conventional type: This type of thermostat does not require any maintenance.

Note: If the room is dark a small blue flash may be noticed when heating or air conditioning comes on. This is normal.

Programmable / Electronic types: Annual replacement of batteries is necessary for proper operation where applicable.


  1. This type of thermostat normally maintains the temperature within half of 1ºC, unlike conventional thermostats, which may vary up to 3ºC. The furnace or air conditioner may cycle more rapidly especially under low load conditions. This is a normal operating condition.
  2. Programmable Thermostats can conserve energy and save you money.
  3. Do not set back your temperature more than 3°C. A temperature difference of more than 3ºC will not provide any savings.

Registering Your Plumbing & HVAC Equipment

Equipment registration activates your extended parts warranty. It is also important to record your product purchase to ensure that you can be contacted in the event that there is a recall or other important product information to share.

With online product registration available, the process is quick and convenient. To register your furnace or air conditioner, all you need is the serial number, model number and installation date for each piece of equipment.

Registration must be completed within 30 days to activate the extended warranty.
