Q:
My furnace isn’t working, what could be wrong?
A: There are several things that you can check before calling a service technician. Change the batteries in your thermostat. Check your filter (a dirty filter will cause lack of airflow which could possibly trigger the high limit trip out on your furnace). Listen to the operation of your furnace. Listen for the small fan to come on, you should see it glowing orange or hear a clicking noise for the ignitor, then you should see flames, then the blower motor should come on. If one of these fails, you’ll need to call a technician, but it will help point to what the issue is.
Q:
There’s water coming from my furnace, what’s going on?
A: You could possibly have a frozen coil (part of the air conditioner). Shut off your air conditioner. Check your filter. If it is clean, you either don’t have enough freon in your unit, or have too much freon. You’ll need a technician with gauges to determine what the current pressure is.
Q:
How much will a new furnace cost me?
A: Furnaces need to be sized to your home. A high BTU furnace in a small house would not have enough air to fire up properly, causing it to trip out on high limit constantly. A small BTU furnace in a large house would run all the time and burn twice as much fuel necessary to adequately heat your home.
