We have a gas furnace that intermittently, 20% of time, starts with a loud boom, it seems the main burner doesn't always catch light from the pilot so some gas builds up then there's a boom. The furnace is regularly serviced and the service people have been told of the problem, they always dismantle the burner and reassemble it but the problem remains. Aside from this the furnace works fine.Any suggestions?Thanks,Peter

Peter should certainly contact the service company that did the non-working repairs and let them know that he had the problem fixed by another repair company and what the problem was. That way, the first company can offer to provide a refund. But more importantly, it gives the company a chance to educate its repair person(s) so that they don't repeat the misrepair to someone else's furnace, with perhaps more serious consequences that just loud booms.
