Winter is the worst time to have your heating system stop working, but that’s often exactly when a breakdown occurs. Fortunately, if you pick up on the signs early enough, you won’t need to go without heat for long and your repair technician should be able to resolve the problem before it gets too bad.
Your Boiler Blows Cold Air
Put your hand to the vent and see if you are getting warm or cold air. When the boiler first starts up, it will likely push out cooler air, but it should rapidly warm up. If the cool air continues to blow, there’s something wrong somewhere and you need to have it seen as rapidly as possible. Cold air will do nothing to warm you up.
