When I purchased my current house, there was a gas furnace installed.
I didn’t love the idea of having a gas furnace instead of an electrical one, but I loved everything else about the house and it felt like something I could look past. As soon as I moved in, I called an HVAC company so they could come examine the entire HVAC system but especially the gas furnace. I wanted to make sure that everything was running safely with the gas and speak to an HVAC professional about proper maintenance before I began using it to heat my home. The HVAC professional was really understanding of my concern and he validated my feelings by explaining that a lot of homeowners with gas furnaces had the same concern. After looking at the gas furnace, he assured me that it was running safely. He even checked for carbon monoxide detectors around the house and found one. The HVAC professional suggested that I install a few more carbon monoxide detectors just to be safe. He also said that I needed to keep a close eye on the carbon monoxide detectors to make sure they had working batteries. Other than the carbon monoxide detectors though, the best thing I could do to keep my gas furnace running safely was hiring an HVAC professional to come service it at a minimum of twice per year. This would not only keep the gas furnace running efficiently, but it would also bring me peace of mind.
