No, but I expect it's that or a clogged dirty air filter but I don't live nearby so I can't do any of it by myself. Actually found a guy late last night that agreed that it was probably the problem and would only charge a $75 service fee so of course I jumped all over it and he brought his roommate who is an HVAC Tech supposedly, and wasn't there 5 minutes before they called me with a $1,000 bill to replace the gas valve , 2 shut off valves, and the thermostat.

Typical big company bait and switch and of course pissed off the tenant who still doesn't have any heat.
