A typical tour of a house that our highly experienced inspectors would take prior to giving the homeowner an estimate or recommendation include:
- Furnace – check existing furnace capability and efficiency; blower configuration (up-flow, down-flow or horizontal)
- Furnace venting – newer, more efficient furnaces radiate less heat than older systems
- Flue or chimney liners may be required to reduce their size.
- Without liners, a more efficient system may not put out enough heat to fill the volume of the ducts. which can let cold air enter the chimney or flue.
- This can cause condensation and moisture buildup in the chimney.
- When combined with the flue gases, this moisture forms an acid that can actually eat into material.
- Additionally, this water buildup can seep into the mortar and freeze in the wintertime.
- As the water freezes, it expands, which can cause serious, costly, damage to the chimney.
- Many companies do not take this step, as the material is expensive and it is a difficult, labor-intensive operation.
