• What if I smell gas?

  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 natural gas:

  • 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.
• What is the average life expectancy of equipment?

  Most systems have a lifetime of 10 to 20 years. As your equipment gets older, it’s efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it’s age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.
