Richard sets up a combustion analyzer, which calculates furnace efficiency by measuring gasses in the exhaust flue. He makes sure that the burner's air gates are adjusted for the proper ration of fuel to air. "You want the fuel that you've brought to the be burned before it goes up the chimney," Richard says. He also replaces the oil nozzle, which atomizes the fuel just before it ignites, and checks the flame color and shape at the igniter. For either oil or gas, this is a key indicator of stable and complete combustion. In a gas system, this is the time when the burner tubes should be vacuumed clean.
We asked This Old House plumbing and heating expert Richard Trethewey to show us the proper steps that a service professional would follow for an oil-burning forced-air furnace; the basics on a gas system are similar. In both, fuel is mixed with air and ignited, heating a sealed chamber. Fresh, filtered air then blows across the outside of the hot chamber and into the heating ducts. (Homes with radiators have boilers instead of furnaces. These heat water instead of air, but the annual checkup is similar.) In all, the dangerous exhaust from the combustion chamber is vented out a flue or chimney.
Yes. You should expect to pay a diagnostic fee to cover the cost of the technician's visit, the diagnosis of your air conditioner's problem, and a quote for the repair options. You will be advised of the issue along with recommended options to correct it, which may include a system replacement if your unit is old or significantly damaged. If you decide to replace the system, the diagnostic fee will be credited toward your replacement purchase.
