Beckett AFG burner Peerless boiler Honeywell R8184G1427 controller Furnace was install in 2000, I purchased house in 2009. I cleaned the firebox, boiler plates, then replaced the oil filter, oil screen, nozzle, electrodes in 2012. This season it started to puffback (bang). But only after restarting during a cycle. Furnace would start normally. After the boiler reached 6.5-7.0 psi burner will shut down. After psi reaches 4.5-5.0 burner would restart, delay 3-5 seconds then puffback upon ignition. If I shut off the furnace while it is running, and turn it back on (at the on/off maintenance switch). It starts normally no puffback. Anyone have advice/know why it happens when it's cycling back on?

My old HEIL high effieciency unit has to be replaced due a cracked exchanger. I live in Baltimore, MD. The installer deals in Carrier and Trane. I have not had a quote yet (today sometime I hope). This is my first foray into a furnace replacement. Questions for the forums: 1) Are these brands generally reliable 2) What brand will offer me the best value for the money 3) Stick with a high efficeincy model I assume since I already have one at the house? 4) Should I get multiple estimates as long as there is no charge Thanks, Scott
