Water Coming Out of Your Furnace & Other Furnace Issues You Shouldn’t Fix Yourself

Those who are mechanically-minded might want to try to fix their furnace themselves, especially if they’ve developed a problem that is quite common. But, the common furnace issues we outline here shouldn’t be fixed by amateurs. Without professional knowledge, you will not be able to resolve these issues. What’s worse, you may actually make things worse.

1. Why is There Water Coming Out of Your Furnace?

High efficiency furnaces are most likely to develop this problem because they use condensation to cool their exhaust before sending it out.

If you’ve found a puddle near your furnace’s exhaust, your furnace condensate pump may not be working, there may be a leak in the condensation lines, or the furnace’s secondary heat exchanger may be faulty. A professional can tell you which of these is the source of your problems.

Why You Shouldn’t DIY: Furnaces, and the electrical equipment near them, are dangerous when wet. Without professional knowledge, you could electrocute yourself trying to fix the condensation problem.

Further, sometimes a condensation problem is so expensive to fix that you’re better off getting a whole new furnace. If this is the case, asking a professional for their expert knowledge will save you money in the long run.

2. Why is there a Booming Noise coming from Your Furnace?

If your furnace is making a booming, rumbling, or “flexing” noise when it starts up, you’re right to be concerned. Just like with the water mentioned above, there could be a few sources of this problem.

Your ducts may be too small for the size of your furnace, causing the metal to flex and ripple when the furnace comes on. Or, there could be a gas build-up before the furnace starts up, causing it to use up all the gas when it turns on, which makes the booming noise.

Why You Shouldn’t DIY: As this problem may be from gas build-up, you shouldn’t try to fix it yourself. The gas could fuel a fire, or exposure could put your health at risk.

Further, there are many other noises your furnace may make that could indicate other problems. It’s important to have a professional confirm the problem so you don’t waste time and money trying to fix the wrong thing.

3. Why Does Your Furnace Turn Off Early?

A furnace that starts up, but then turns off before your home has reached the temperature you’ve set is an indication that one of the furnace’s internal components is likely damaged. Sometimes this is due to a sensor malfunction, which needs to be cleaned or replaced.

Or, the furnace may be hitting high temperatures, at which point a safety feature will switch it off to prevent fires and damage to the furnace.

Why You Shouldn’t DIY: HVAC professionals will be able to pin point which part of your furnace is short-circuiting, or if there’s a safety issue with the furnace. If you try this on your own, you may guess the wrong part, or let a safety issue go unchecked.

Ultimately, if you’re wondering why there is water coming out of your furnace, or why it has other problems, it’s wisest to call the professionals at ABW Halton ClimateCare for help.
