If you are not satisfied, I'd appreciate it if you'd tell me why before leaving a negative rating and allow me to continue to work with you until we are able to both agree on an outcome to follow. Thanks for your business!
What is the furnace make and model number? Are you getting any LED flash code?
Do you have zone valves?
Single thermostat in the house or more than one?
Are they both for heating?
Do you have zone valves down near boiler? They may look like this. Sometimes a different brand may be used other than Honeywell.
Take the cover off and see if the valve is open. The way you tell is to push the small lever over and if there is no resistance, then it's open. If you turn off that zone and the lever pushes with some resistance, then that valve is closed. Need to know if it's open or closed.
Cover on zone valve. The one you sent me a picture of.
I understand your concerns since it's cold there. That's why I need you to do the things I mention so we can try and figure out what's going on.
Now lets see if any heat starts coming up the pipe.
Tell me if the boiler kicks on.
Is your boiler electronic ignition or a standing pilot? Standing pilot would be the pilot on all the time.
That would be standing pilot. Do you know how to light pilot?
There is a knob on your gas valve. Turn to pilot position, push down, HOLD, and reach in with a long match and light pilot. Continue to hold down for about 60 seconds, then release knob and turn to ON position.
The one on the picture I sent you. Blue arrow.
Did you turn valve knob to ON
If pilot is lit and valve on, either you have a bad thermocouple or not calling for heat. Are the levers on zone valves still in the ON position instead of AUTO?
Probably have a bad thermocouple then. This can be pulled out, brought up to a local hardware and replaced. It is on the pilot assembly. The thermocouple is at the end of this copper line.
Nothing to worry about. Zone valves do that sometimes.
Did you want to work further on this or can we close question out?
Your vent damper. Have all your questions been answered?
