What is the furnace make and model number? Are you getting any LED flash code?

Customer reply replied 2 years ago
Burnham series 2
No flashing I didn't take the cover off yet though
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Do you have zone valves?

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Not sure what that is
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Single thermostat in the house or more than one?

Sorry I'm an idiot l
Customer reply replied 2 years ago
2 thermostats on the same floor
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Are they both for heating?

Ask Your Own HVAC Question
Customer reply replied 2 years ago
only heat. No centra air
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Do you have zone valves down near boiler? They may look like this. Sometimes a different brand may be used other than Honeywell.

Ask Your Own HVAC Question
Customer reply replied 2 years ago
2 of them
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

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.

The cover off the furnace or the blue cap
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Cover on zone valve. The one you sent me a picture of.

Ok sorry
Customer reply replied 2 years ago
They are both on auto? Not on/main

The temperature really dropped I'm in Staten Island , Nyc it's like 5 below
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

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.

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Move the levers both to open
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Now lets see if any heat starts coming up the pipe.

Ask Your Own HVAC Question
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Tell me if the boiler kicks on.

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Didn't kick on. Cap is still buzzing I don't see a pilot light on
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Is your boiler electronic ignition or a standing pilot? Standing pilot would be the pilot on all the time.

Ask Your Own HVAC Question
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

That would be standing pilot. Do you know how to light pilot?

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Not really
Customer reply replied 2 years ago
On the water tank it has a black pilot switch
Customer reply replied 2 years ago
Looking for a match
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

OK

Ask Your Own HVAC Question
Customer reply replied 2 years ago
I have regular matches.. Not long ones.
The pilot on the furnace not the water tank correct
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

The one on the picture I sent you. Blue arrow.

Ask Your Own HVAC Question
Customer reply replied 2 years ago
I got the pilot light on , still loud buzzing, and I didn't hear the furnace kick in yet
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Did you turn valve knob to ON

Ask Your Own HVAC Question
Customer reply replied 2 years ago
lol
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

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?

Ask Your Own HVAC Question
Customer reply replied 2 years ago
What about the buzzing?
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Nothing to worry about. Zone valves do that sometimes.

Did you want to work further on this or can we close question out?
