Tell them to open their ****ing windows.

LOL
They aren't really complaining but the blower isn't coming on for the heater either..
I dont want to look like some lame duck landlord either..so there is that too

but yes the windows are open AFAIK at this point - still needs to be fixed

If the fan isn't working at all then it either lost power, has a bad capacitor or the motor is cooked.

Tell them to check the fuse on the shutoff switch by the furnace.

Approximately how much is it to replace an automatic ignition for a furnace?

The furnace heats and blows fine but late last winter it struggled lighting.

It's sixty ****ing degrees outside

Should have read farther.

doh

Struggled lighting the pilot flame, or the burners?

Pilot flame. When it lights the burners always quickly followed.

Ah, gotcha. As far as cost, I don't think that would be a very expensive fix but it could vary widely depending on the brand of the furnace and the labor rate and markup of who you call to fix it. If it's easily accessible you might just try cleaning the thing up first.

Thanks for the knowledge, Bugeater.

Do I want to keep my attic space open or closed in the summer?

Big trees around your house will help, too.

Since my online stalker bumped this, I'll take the opportunity to mention that now is the time to check your condensing units and make sure they don't look like the one in the OP. And even if they don't it's not a bad idea to hose them out anyway.

so, realized my ac is not working this morning.
last year, the ac guy replaced the outside fan. seized up, wouldn't move. fans inside blowing air, just not cold. went outside,fan is off, pressed the small red (reset?) button, unit kicked on. the goddamned fan doesn't move (just like last year), but the unit kicked on, while the fan is not.
what's the general warranty on parts like this? why the hell did it freeze up again? why why why why why?

(any advice is greatly appreciated!!!)
thanks in advance
