Calgary furnaces: Guide to How Furnaces Work

Homeowner’s Guide on How to Operate a Calgary Furnace

If you question the majority of Calgary homeowners as to “how does their furnace operate,” their usual response is that “it keeps them comfortable and warm.” Even if that is correct, a furnace’s actual operation involves more detailed processes.

You can cross your fingers and hope that your furnace will run as smoothly as possible for a lifetime, but Calgary furnaces will require repairs over time. Comprehending the necessary repairs or replacements your unit need, and for you to figure out right away if something is amiss with it,a basic understanding of your furnace’s entire operation comes in handy. It is not as if you must be adept at changing a blower motor if necessary, but more like being enlightened as to how your unit keeps you warm and cozy every night.


By setting your thermostat, you essentially set an alarm as to when your furnace starts working. As soon as your thermostat notices the change in your home’s temperature, it will automatically start working,and its heating cycle starts. A major reason for you to require the services of a Calgary furnace repair is a broken thermostat. It is of prime importance since it is like your furnace is waiting for instructions that have no chance of coming through at all. In some scenarios, your thermostat is disconnected and is no longer reading the right temperature. Hence, it stops cycling or inversely continues running nonstop that will incur skyrocketing heating costs. A lot of homeowners are primarily hooked to a programmable thermostat because they like coming home to a warm house after a frigid day outdoors. Another good feature is that it automatically lower your home’s temperature the entire day when no one is at home to manage your household’s heating costs.


As soon as your thermostat determines that it is high time to run your furnace, it requires air to start the heating process. Soon enough, a fan kicks in to suck air from within the room or outside to initiate the combustion airflow. However, a lot of people have been debating about this for so long as to where is the most efficient air coming from. One side says sucking in air from outside your home establishes an open-loop system that significantly takes in more pure air in contrast to the air coming from a boxed up utility room or perhaps an unfinished basement. Meanwhile, the other camp claims that the air from outside is way too cool during winter season, which puts undue strain on your Calgary furnace. But then, regardless of the air’s source, it goes through several processes to purify it and to attain the ideal room temperature. The air starts to warm up as soon as it reaches a sufficient flow.


A common complaint among homeowners that necessitate a Calgary furnace repair points to its ignitor and gas valve. In the long run, a furnace that doesn’t warm up the air in your home is outright useless and a big waste of money. As soon as your ignition fan has sucked in a sufficient amount of airflow to initiate combustion, your unit’s gas valve opens up just like what you do when you turn on your kitchen stove. The gas reaches its burners that allow the ignitor to establish a steady flame. A lot of old furnaces resembles a stove. It comes with a built-in pilot light that burns the gas whenever it is on rather than an ignitor doing it. Its pilot light constantly goes out and requires a homeowner to light it up once more. This one is another concern for Calgary furnaces. Modern furnaces utilize an ignitor that turns off on its own as soon as it senses the presence of flames.


After taking care of the ignition, you are not yet done. The majority of burners work for several seconds up to a minute to make sure that only warm air is led to the vents and out into your room. As soon as the flame becomes very hot, it signals the blower motor to start working and push the air into the unit’s heat exchanger. The heat exchanger is responsible for taking the cold out of the circulating air and makes it warm so you’d feel warm and toasty as it moves through your home’s duct system. Your furnace will either operate in response to a preset time or once it satisfies your thermostat. You can speed up the job of your furnace by increasing the thermostat’s temperature. However, it wears down your unit with the continuous rise and fall of the system.


As soon as your thermostat recognizes that the ideal temperature inside the room is achieved, it initiates the shutdown process. The gas valve turns off leaving the furnace without any fuel to power its operation. The unit’s blower motor keeps on working for a few more seconds as it tries to cool down its heat exchanger that is all worked up from the entire heating process. Furnace Repair Calgary regularly works on heat exchanger issues, especially during winter, secondary to the extreme strain it goes through each day. When the unit’s heat exchanger achieves the set temperature on the switch, or when the blower works after a certain period, the furnace turns off.It then lies in wait until the next time your home needs some serious heat.

You are not expected to become a pro when it comes to repairing Calgary furnaces, but to grasp the fundamental ins and outs of the operation of your furnace will not hurt you either. In truth, you will be able to pull off your own diagnostic stunts if you just observe the process we have shared earlier. For example, a running furnace that send out cold air instead of warm air points the problem to your heat exchanger. Whereas hearing a running sound way after your furnace has turned off indicates that you still have a running blower motor.Like what a popular comic soldier said in the past, “knowing is half the battle.”
