Furnaces are meant to last a long time – and usually, they do live up to expectations. But as always, not all homeowners know how to take care of their furnaces. In effect, these machines wear down more quickly than they should. The good news is that this is avoidable.
Heating contractors in Salt Lake City say that preventive maintenance is always a good way to keep the machine in top shape. But more than anything, it is important to remember one thing: to not reduce the airflow in the furnace itself.
The experts say reducing the airflow is the absolute worst thing you can do to shorten the lifespan of your furnace. Inside the machine is a metal coil known as the heat exchanger – and it’s the part responsible for increasing the temperature of the airflow. The blower sucks in air and transfers it to the heat exchanger, which then cranks up the heat.
Now, cutting down the airflow deprives the heat exchanger of sufficient air to heat up. As a result, it overworks itself with little to no opportunity to cool down. Once it overheats, it cracks – and that’s that, you have to call a technician at that point.
Most probably, you think you don’t do this thing anyway so you’re good. Then again, maybe not. Sometimes, homeowners cut down the airflow by accident – and there are many instances in which this happens.
For one, closing the air supply vents increases the pressure in the duct system. The blower has to work in an environment with a set pressure level, and altering this could have an impact on the airflow. Simply covering the vents with drapes – or even heavy items like furniture – could result in this. Forgetting to change the filter also contributes to this, as the dirt prevents the air’s free flow.
You wouldn’t want a furnace breakdown to happen, so try your best to prevent it. Avoid cutting down on air flow to ensure your machine stays in top shape for the longest time possible.
