Ten things you should consider when buying or renting a new High Efficiency Furnace in Toronto, GTA and Ontario

Buying a new High Efficiency furnace in Toronto, Ontario can seem overwhelming.

With all the information about high efficiency furnace, HVAC systems and efficiency levels on the web; it is very easy to get carried away.  Here are 10 things you should consider before purchasing a new HVAC system in Toronto and Ontario:

1.      How can I tell if a furnace is really energy efficient

Select furnaces with efficiency values of at least 94%.  The ideal bet is to select a furnace with an EnergyStar® label, which will indicate that this model is the most efficient in its class of furnaces.

2.      What size of the furnace should I purchase?

Most gas furnaces in Canadian households are oversized.  A high-efficiency furnace should be sized 30-40% larger than the calculated heating requirements of the specific home.  If you want to figure out exactly what size of a new high efficiency furnace your house needs ask a specialist.

3.      Should I get single stage, multi stage or two stage furnace?

An efficient furnace with a two-stage and multi-stage burner burn fuel at different rates.  Low-fire settings, which are more efficient, they will provide enough heat to keep the entire house warm in most weather.  In colder weather where additional heat may be required; be sure to set back temperatures within a reasonable amount of time, these furnaces will shift automatically to high-fire settings to provide added warmth.

4.      What type and size of motor should I get?

It is important to take into consideration how much electricity the furnace blower fan motor will use.  Oversized motors could end up costing the owner more to operate.  This is very true when the furnace fan is used with a central air-conditioning system.  Be sure to ask your supplier to confirm that the motor is properly sized for heating and that it will deliver heat evenly to all rooms. A DC variable speed motor will be the most efficient type. Although DC motors usually will run at a cost of $500 to $800 which is more than alternatives, they save money in the long run.

5.      What is the best brand and model of furnace?

You can search various brands and models of high efficiency furnaces in the The Consumers’ Directory of Certified Efficiency Ratings for Heating and Water Heating Equipment. It is also a very good idea to ask your supplier for suggestions as they will know more details on furnace brands, their warranties and efficiency.

6.      What kind of thermostat should be I be chosing alongside my new high efficiency furnace?

Buying a thermostat that can be manually programmed to perform temperature setbacks over night and when the house unoccupied for more than multiple hours will be the best choice.

 7.      Will there be a need to modify the combustion air supply?

In most situations, when performing the installation of high-efficiency furnace the combustion air supply can be reduced in size significantly.

8.      Will my new furnace be compatible with the central air conditioning?

Furnaces that are being used in conjunction with central air conditioning will need to be circulated with more air than those used solely for heating.  This is in order to ensure that the cooling coils do not freeze up.

9.      Will I be required to have a condensation pump?   

Some situations may see a small electric pump installed with the furnace to pump furnace condensate to your sewer. Make sure to ask if a condensate pump will be required.

10.  What else should I be asking for?

Ask your contractor to quote on:

• Remove the old furnace from your home.

• Modifications to existing ductwork, if required.

• Modifications to the wiring to the furnace.

• Installation of vents and any modifications to the chimney.

• Cost of permits and inspections.
