Air Conditioning

In summer, high relative humidity, elevated air temperatures and sunshine can combine to produce an uncomfortable indoor environment. Air conditioning can provide comfort by lowering the air temperature and also the humidity level in the home. When you're in the market for new cooling products, it pays to learn all you can about them first. With the proper facts in hand, you can make choices that will save you money and help protect the environment. You might also want to take a look at our ductless options. A ductless unit is suitable for apartments, condo living, boiler heated homes and homes without ducting.

There are three main cooling options available:
• central air conditioners
• heat pumps
• room air conditioners

The EnerGuide rating and ENERGY STAR® symbol can help you identify the most energy-efficient products available in Canada.

Central air conditioners cool only, while heat pumps also provide heat in winter. Central air conditioners and heat pumps are used to cool an entire living area. Room air conditioners can effectively cool up to three rooms at low cost, and can be installed with minimum effort.

Before you decide what to buy, ask yourself if the whole house must be air-conditioned or if your needs would be satisfied by cooling one or two rooms. The answer will determine which type of air conditioner would be more appropriate.

No cooling? What to do before calling for service

The “before you call” 8-point checklist
If homeowners are not comfortable checking these items, they should call a technician.

If a/c unit outside is not on at all, check fuse or breaker. If breaker is tripped off, reset.

Ensure furnace filter is clean. If it is plugged with dirt, etc. replace the filter, turn the system off for 2-3 hours and restart.

Check your thermostat. Make sure it is set to the ‘cool’ position and also that the temperature has been turned down.

Check for ice build up. This could be caused by a dirty air filter or thermostat set too low. If there is ice build up, shut a/c off and let the ice melt.

Check thermostat batteries.

Check outside disconnect. When the box is opened, the black piece inside should say ON.

Check exhaust pipe which is located outside to make sure it is clear or debris.

Make sure you removed the winter a/c cover.
