Type B (B-vent) chimneys and HVAC contractors
Forget the chimney repair, tear it out.
If your gas appliances are using B-vent, they're probably old,
inefficient and wasting your hard-earned money.
Replace them with high-efficiency models that vent horizontally with pvc
pipe thru the side of your house. They'll actually pay for themselves in
a few years or so.
