Air Flow Issues

This is a common issue that we deal with on service calls. This happens when you turn your furnace on but only a small amount of air comes out of your registers. Here are some common causes:

  • Clogged air filter – A dirty air filter can cause a ton of problems for your furnace and low air flow is definitely one of them.
  • Blower – The blower is the fan that pushes the heated air through your duct work. If the fan’s belt, bearings or motor aren’t in good working order, you may be experiencing low air flow.

Strange Sounds and Flame

Your furnace can make sounds when it operates and this is normal. However, there are some sounds that you’ll want to watch out for as they can be an indication of a dangerous problem. You’ll also want to watch the flames on your furnace if you have a gas-fired furnace as this can be an indication of the same dangerous issue.

  • Rattling sound – If your furnace is making a rattling sound it could be loose screws or covering on the furnace. However, it might also be that the heat exchanger in your furnace is cracked. The heat exchanger is designed to heat the air and also exhaust dangerous combustion fumes. If it is cracked, those fumes might be getting sent out into your home.
  • Yellow, wiggling flame – The flame on your furnace should be blue. But if you notice that it has turned yellow or has started to wiggle, this can also be an indication that your heat exchanger is cracked.


The thermostat for your home in Suffern is what tells the furnace to turn on or off. Obviously, if this breaks it can cause a lot of problems.

  • No heat or low heat – If your furnace isn’t providing enough heat or no heat at all, it might be the thermostat. You should check to make sure that the pilot light or igniter is working correctly and that the furnace is lit.
