IS IT NORMAL TO SMELL GAS WHEN HVAC IS RUNNING?

Residential furnaces that are powered by natural gas are one of the most common types of home heating systems in the area. Sometimes with these systems, there can be a malfunction which may lead to funny smells coming from your vents or around the furnace. Though it is uncommon for the system to produce a gas smell, it is important to know what to do if it happens, as this could be a very serious concern.

Propane (LP) gas: You have this type if your gas comes from a tank located outside close to your house. Propane is stored as a liquid under pressure in tanks and cylinders. In most residential applications, propane is used as a vapor. When liquid propane changes into a gas vapor, it expands in volume. This means that even a small leak of liquid propane can result in a much larger quantity of propane vapor, which can be especially dangerous in a confined space. A chemical odorant has been added to propane to give it a distinct smell. Learn to identify this odor. Propane gas is heavier than air, so it will sink to the floor and spread. To check for the presence of propane, carefully smell all over a room, especially in low spots.

If you smell propane (LP) gas:

  • Exit your home immediately.
  • Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
  • From a safe area, contact your propane supplier and call 911.
  • If you are able, shut the propane gas supply off at the tank.
  • Stay away from your home until you've been told that it is safe to return.

Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor. If you smell gas faintly, check all areas of your house for strong odor. If the smell is only faint throughout all areas of your home, call your heating contractor to get it fixed within 24 hours. Keep the house well ventilated by opening windows.

If you smell a strong, persistent odor:

  • Exit your home immediately.
  • Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
  • From a safe area, contact your gas company or call 911.
  • If you are able, turn the gas off at the meter.
  • Stay away from your home until you've been told that it is safe to return.
