Heating Frequently Asked Questions
What Size Gas Furnace Do You Need for Your Home?
Unless you are HVAC professional, it's almost impossible to determine the size of a replacement furnace. A trained heating specialist knows all the standards and can evaluate your home for not only the heating appliance, but also the quality of the heated air, and proper air distribution in your home. The " Heat Loss,Heat Gain" calculation is necessary to determine the proper furnace size in some cases. Also changes made to the home since the previous furnace was installed should be taken to the consideration. New windows, doors, wall and attic insulation, exterior changes, additions and other appliances that may have a huge affect on the size of the furnace needed today. A consumer can tell a contractor the exact furnace they now have, but without a complete home analysis, it's impossible to determine the proper size of the replacement furnace equipment.
When Is The Right Time To Replace a Gas Furnace?
There are many factors involved in determining the best time to replace a furnace, such as its current operating efficiency, condition, make, model and the age of the furnace. A very basic rule-of-thumb is that every 10 years. This is a somewhat broad generalization, many well-maintained furnaces may last much, much longer energy-efficient heating, and less quality models may only last a few years. The only way to really know the best time to replace your furnace is to have an HVAC inspection and energy analysis performed on your heating and cooling system. We offer this service as part of any appointment, but you might get the most use of the information for free by scheduling a certified technician to perform the analysis and discuss the furnace options available to you. Every home and person is different, a Comfort Adviser can help you find solutions customized for your specific home and family’s comfort needs.
How Often Should You Maintain Your Heating System?
Maintaining your heating system is good for you and its also the law. Annual regular maintenance is recommended by all heating equipment manufacturers. Most Canadians pay very little attention to their home heating systems - except when they fail. Regular maintenance, however, is not only a good idea, it is actually a legal obligation.Most provinces in Canada have fuel safety regulations that put the burden on the owners of furnaces and boilers that burn fuel (oil, natural gas or propane) to “maintain equipment in safe operating condition”. These regulations exist because, though incidents are rare, there is always a risk that improperly maintained equipment will cause harm to building occupants. But maintenance of home heating systems is not just about ensuring safe operation of the equipment; it is also about making that system work as effectively and efficiently as possible, so that thermal comfort is assured throughout the home (or building) and energy consumption is minimized.While homeowners can safely handle basic routine maintenance, such as replacing air filters on a furnace, annual maintenance needs to be done by properly trained technicians with the appropriate fuel safety certificates and trade licenses. Fortunately, there is a whole industry of trained and licensed professionals available to assist homeowners and commercial building owners in meeting their equipment maintenance obligations. The Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) requires its contractor members to hold the appropriate credentials (including fuel safety licenses and trades training certificates) to do the work they do.
What is Carbon Monoxide?
Carbon Monoxide or CO for short is a by product of incomplete burning of fuels, including wood, heating oil, propane, natural gas, kerosene, gasoline, diesel fuel, coal or charcoal. Equipment that are not maintained properly, inadequate fresh air supply for safe burning and venting of exhaust gases, and a deteriorating or blocked chimney or flue can create a carbon monoxide hazard in your home. Careless use of equipment can also create such a hazard. If you suspect carbon monoxide is present in the home, open windows immediately to allow fresh air inside. Turn off all heating appliances.If you feel weak or need emergency assistance call 911 immediately.Seek medical advice for physical symptoms and have a licensed gas contractor inspect your home and gas appliances. Carbon monoxide poisoning is a real threat in today's energy efficient houses. Most modern houses are so tightly sealed that carbon monoxide cannot escape as easily as it can in drafty old houses. Carbon monoxide detectors can help. You should check your CO detector annually to make sure proper operation.
Tips to Reduce Your Home Heating Costs
  • Install a digital programmable thermostat and set it 3°Celsius (5 ̊ Fahrenheit) lower when you’re asleep or away from home
  • Clean, inspect or replace your furnace filter every three months
  • Seal drafty windows, doors and electrical sockets with weather stripping or caulking
  • Keep drapes closed at night and open on sunny days
  • Set your water heater dial to 120°F
  • Install a heat recovery ventilator (HRV) to recover lost heat from the building
  • Using your dishwasher instead of washing dishes with your hand and save up to 40% in energy usage
What is Heat Exchnger?
The heat exchangers in forced air high efficiency furnaces, typical in residential systems, are made of two parts. Primary and secondary heat exchangers which are interconnected. In residential and light commercial applications, heat exchangers are gas to air or oil to air systems that are typically made of stamped stainless steel sheet metal or tubes for durability and fast heat transfer. The combustion products pass on one side of these heat exchangers, and air to heat on the other.Condensation water produces during combustion. Condensation water is corrosive and can damage the heat exchanger over time if it's not made of durable materials. For instance Carrier secondary heat exchangers are defective due to use of propelyne to laminate inside secondary heat exchangers. for more information on Carrier Heat Exchangers Click Here
The combustion products pass on one side of these heat exchangers, and air to heat on the other. A cracked heat exchanger is therefore a dangerous situation that requires immediate attention because combustion products may enter living space.
