In the past – heating contractors developed the poor habit of oversizing furnaces to be on the safe side. It was not as serious an issue back then since energy costs were a lot less than they are today. The combined losses in efficiency due to an oversized furnace and chimney liner is much more of a loss with today’s energy costs than ever before. An oversized furnace will always cost more to purchase, more to install and more to operate and maintain. Therefore, it becomes extremely important to properly evaluate and calculate the actual heat loss.

Sizing A Furnace

Today’s heating contractor typically will size a furnace to no more than 10-15% higher than the actual heat loss of the home. At Tradesman Mechanical – we can input all of the required values into our computer heat loss program for an accurate assessment of your home. These will include wall dimensions & construction, insulation values, colours, type of basement, windows, doors, number of occupants, lifestyle & more.

Buying a furnace means buying the right furnace for your home or business, and now, right here on our Web site, we provide you with the information that you need to make an informed decision. Featuring our unique; Heat Loss Calculation Tool, free for your use.

Once you have completed the Heat Loss Calculation Work Sheet - Please Fax to (204) 831-7713. Please allow 2 working days for a response.

Please note you will need Adobe 5.0 or higher. 

Hot Tips

  • Replace the batteries in your digital thermostat annually and avoid a no-heat situation.
  • A clean air filter is a cheap and simple way to reduce failure and operating costs. Mark the dates on your calendar as a reminder.
  • Programmable thermostats will keep your home comfortable while helping you avoid paying for heating or cooling when you are not there to enjoy it. - Energy savings of up to 10% may be realized and will pay for itself in as short as one season of operation. - Set back of more than 7-8º will offer less savings due to recovery and is not recommended.
  • Opening curtains and blinds allowing sunlight into your home will generate free radiant heat. Window coverings will reduce heat transfer at night keeping the wwarmth inside.
  • Fireplace dampers should be closed when not in use. Chimney drafts can allow unnecessary heat loss. A fireplace flue that is never used, should be properly sealed off.
  • Humid moist air will feel more comfortable than dry air at the same temperature. Maintaining the humidity in your home will provide personal comfort at a lower temperature setting and save you money.
  • Remove all flammable items from around your furnace and hot water heater. Paints, aerosols, solvents, boxes and clothing should not be stored near this equpment.
  • Furnaces and water heaters require combustion air for safe and efficient operation. If your gas burning appliance is isolated in a sealed room or closet, a combustion air duct or transfer grilles should be installed.
  • Save energy by closing off dampers to areas not in use.
  • Never close off more than 25% of your dampers or vents. reducing the total airflow through your system beyond this may lead to problems. - Low airflow will affect the temperature rise through the heat exchanger and may lead to unsafe operating conditions and equipment failure. Low airflow will also affect the temperature drop when in air conditioning mode. This may lead to freeze up of the evaporator (cooling coil).
  • Consider replacing your furnace if it is more than 15-20 years old. Any repair costs would have been better spent on a more efficient new system that will also provide you with lower operating costs.

Another important thing a homeowner can do for the environment; regardless of the refrigerant used is a selected reputable dealer that employs service technicians who are EPA certified to handle refrigerants. Technicians often call this this certification "Section 608 certification," referring to the part of the Clean Air Act that requires minimizing releases of ozone depleting chemicals from HVAC equipment.

The maximum term is 5 years for all energy efficiency upgrades and 15 years for the purchase of a high efficiency natural gas furnace. Applicant must be a Manitoba Hydro customer and the owner of the home in which energy improvements are to take place. Appointments are limited and Real Estate Agents welcome.


To Repair or Replace

One of our comfort consultants can explain all of this in more detail if you wish, and will calculate a Payback Period to help you make a more informed decision. The physical life expectancy of a Furnace or Air Conditioner can often be longer than its economic life. You may also use the following link to help you calculate a true payback period on this investment. Future costs of fuel and energy will tend to go up more than down.

Ventilation::HRV::ERV::Central exhaust::Air exchange::Air Quality::Humidity control

Environmental concerns for air quality have been known to us for decades, but only recently have we seriously begun to address the quality of indoor air, the air that we are exposed to the better part of our lives, the air in our homes. High efficient air-tight homes help reduce energy costs, but have a negative effect of reducing air changes, keeping higher concentrations of airborne contaminants trapped inside.
