Learn about propane. You can request information from local dealers, or you can visit any number of websites that offer free access to information about heating with propane, such as the National Propane Gas Association's website.
Find out if it is possible to convert to propane heat by having one (two or three is better) HVAC contractors come to your home to examine your existing system and advise you.
Seek estimates from at least two or three HVAC contractors or local propane dealers on the cost of installing or converting to propane heat. If you are converting, make sure that the estimates include all costs, including those for removal and disposal of the old system components.
Make sure you have the HVAC contractors scope your yard for a place to position a propane tank. Safety codes differ from area to area, but almost all municipal codes have minimum distance requirements for safely locating propane tanks away from buildings. Some propane dealers will bury your tank, depending on how large it is and how much volume you will use.
Ask your HVAC installer to teach all the members of your household how to identify a propane leak and what steps should be taken once a leak is suspected.
Install carbon monoxide detectors and smoke alarms throughout your home if you don't already have them. Replace the batteries in existing detectors and alarms every six months.
