system before and are familiar with it, the best thing to do here is to check the data plate. The data plate also has the manifold pressure, minimum and maximum gas pressures, and all sorts of information that will be useful later. With all that in mind, it may be beneficial to activate the equipment from the thermostat. If you raise the setpoint, you can see how the equipment operates. Whenever the system fails to start or does something odd, you can have a conversation with the customer before taking anything apart. 2. Check for water leakage around the system (on high-efficiency furnaces). If you're working on a 90%+ furnace, you will want to inspect the gaskets, condensate drain, and blower compartment closely for signs of water leakage. If you see evidence of water leakage, then you might be dealing with a failed component like a gasket, cracked collector box, or secondary heat exchanger.

Gas Furnace Maintenance Procedure

Gas-fired equipment has a different set of components than your typical straight-cool A/C unit or heat pump. With gas pressures to test, sensors to clean, and combustion to analyze, it can be difficult to figure out where to begin a maintenance procedure on a gas furnace. So, here is a start-to-finish guide to a thorough gas maintenance procedure developed by none other than Michael Housh. As with any other type of HVAC system, gas furnaces require you to do a thorough visual inspection before you even touch your tools. 1. Familiarize yourself with the equipment and see how it operates. Check to see what the furnace efficiency is; are you dealing with a standard 80% furnace or a 90%+ high-efficiency furnace? Does the system use natural gas or liquefied petroleum (LP or propane)? Unless you've worked on a Visual inspection
