Pro-tip: Read on if you have a gas furnace………..

I think that 99% of furnace problems are due to some issue with flame sensor, flame roll out switch or furnace limit switch…..

Not cleaning your furnace and not changing filters causes problems with those 3 things……

Change your filter and clean your furnace and keep above 3 items on standby and you will avoid problems with no heat at midnight……….
