We want to be clear about this from the start: Only a trained, licensed HVAC professional should repair a gas furnace. This is a matter of safety—although even if it were safe to tinker with a gas furnace on your own, you’d still only want a trained professional to touch the system to make sure the repair is done right. In many jurisdictions, it’s illegal for anyone without a special license to work on an appliance connected to a gas main.
In this post we’re making a distinction between trying to repair a gas furnace and going through basic troubleshooting steps when a furnace isn’t working properly. There’s nothing wrong with making checks on a furnace before you call us for heating repair in Plattsburgh, NY. Often, the problem with a non-working furnace is something simple you can correct on your own. Just don’t take any steps where you need to get tools and open up the furnace! That’s the point where you’ve gone past troubleshooting and might get into actual trouble.
