Electronic Ignition Gas Furnaces | HVAC Heating
While the three are different they all offer higher efficiencies and are both controlled by solid-state circuit boards. Many of these furnaces also have higher efficient heat exchangers.

Gas Furnace Components | HVAC Heating Systems
Gas Furnace Components | HVAC Heating Systems. Different types of gas furnaces are available for purchase today and the older models which were installed many years ago still in operation. The older models were typically atmospheric-type gas furnaces and used a lot of gas to produce heat, much of which went up the flue because efficiencies were low.
The standing pilot atmospheric type gas furnaces still exist today, but they are slowly going the way of the dinosaur as newer more efficient furnaces are replacing them. (more…)
Gas Valve Troubleshooting | Diagnosis and Repair
Gas Valve Troubleshooting - Gas valves used in modern state-of-the-art residential gas furnaces are typically controlled via a state-of-the-art electronic ignition control or a printed circuit board. Other types of gas valves include the standing pilot gas valve.
Gas valves can be found on gas furnaces, gas-fired steam boilers or hot water boilers, and gas-fired water heaters. With gas valve troubleshooting and any “gas valve” issues, safety is always first.
When troubleshooting a gas valve, the technician should only be concerned with input to the gas valve and output of the gas valve, whether it is an electronic module or circuit board controlled gas valve, or a standing pilot gas valve. The input with gas valve troubleshooting includes ensuring the safety circuit is good.
