Furnaces can be extremely dangerous if they are not cleaned and maintained on a regular basis. The main hazards are aggravated asthma and breathing problems, usually caused by poor filtration; gas or oil leaks, which create a fire hazard; and carbon monoxide leaks, which are very deadly. A poorly maintained furnace may also be a health risk because it can cause airborne pollutants such as mold, bacteria, and particulates to be released into your home.
Furnace maintenance involves the cleaning and inspection of a furnace’s heating elements, blower fan, duct work, thermostat and electrical connections. It also includes lubricating moving parts and ensuring all safety controls are working properly.
Performing these routine tasks helps the system to operate more efficiently, which reduces fuel usage and lowers utility bills. It is best to complete these tasks before the heating season starts so that the furnace can be ready for use when needed.
Most manufacturer warranties require yearly furnace maintenance to uphold the warranty. This will protect you from costly repairs if the unit should break down, and ensures that you are fully covered.
Professional maintenance services include the following:
Checks for a carbon monoxide leak. https://www.eheatcool.com/services/heating/furnaces/maintenance/ release carbon monoxide as a byproduct of combustion. This is normally vented out of the house through an exhaust pipe, but if this system is not functioning correctly, it can leak into the home. Licenced professionals will inspect the venting to make sure it is intact and that there are no cracks or gaps.
Cleans the blower fan and heat exchanger. Keeping the blower fan and heat exchanger clean ensures proper air flow and efficiency. This will also help to minimize any dust or debris that is circulating in the home.
Inspects the flame sensor. This is a small device in the burner assembly that tells the system that there is a flame present. If it is not burning blue, this is a sign of a problem and should be checked by a professional.
Tests the thermostat for correct operation and temperature control. This includes a verification of the fan speed, the thermostat set point and scheduling, and the actual operating temperatures. A licenced technician will also test the temperature sensors to ensure they are reading accurately.
Examines all ductwork for potential leaks or blockages. Leaky ducts can result in poor heating throughout the home and can even lead to mould growth. The technician will also test the return air and hot water vents for any signs of corrosion.
