Common Furnace Questions

Sometimes problems occur with your furnace that are beyond what most of us understand. At Schmidt Mechanical, we receive many inquiries about these complex appliances and want to share a little information with you so that you know what to do in the event that your furnace has a hiccup:


Why is my furnace leaking water?
Do you notice water puddling around the furnace? This might be a sign that the condensate drain is clogged with slime. Either that or the floor drain has clogged up. Check the drain and clear if necessary. If you’re not sure how to handle such equipment, ask your HVAC technician, as this is an easy fix for them.

Why is my furnace not kicking on?
Furnace not turning on? First, make sure the thermostat is on (and switch to “heat”). If it’s already on, you might need to change the furnace filter to clear any dust. Still not doing the trick? Check for blocked or leaky ducts that might be stopping air flow and seal them. Call for HVAC service if none of these solutions solve the problem.

Why is my furnace not blowing hot air?
If your furnace is not providing you with warm hair, then chances are you need to replace the filter. This is an simple and common solution that can fix many furnace issues. But if that doesn’t kick your system into gear, check that the circuit breaker is on.

Why is my furnace blowing cold air?
Having the opposite problem? In the event that your furnace isn’t blowing enough cold air to keep you comfortable, make sure the pilot light isn’t out or the furnace isn’t overheated. Ask an expert for help if none of these solutions work for you.
