The following statement(s) is/are true about SEER (Seasonal Energy Efficiency Ratio):

8 or 10 SEER is the current minimum efficiency manufactured.

13 or 14 SEER is the current minimum efficiency manufactured.

Units before 1995 may be only 4 or 5 SEER.

Units with a higher SEER are approximately the same physical size as units with a lower SEER (but this is starting to change).

The previous standard for SEER was 5.

13 or 14 SEER is the current minimum efficiency manufactured.

When inspecting an AC unit installed in an attic, what is the foolproof way to ensure leaking is detected and doesn’t spill over onto the floor or ceiling?

You should see a proper drip pan.

You should see a drip pan and a drain on the pan that flows out the side of the house.

You should see a drain that carries the water to the basement.

You should see a drip pan and an emergency float switch.

A float pan is not necessary because in warm weather, the hot air in the attic causes quick and efficient evaporation of the water.

Safety precautions when working in an attic include wearing a dust mask and gloves, using a headlamp or flashlight for illumination, and walking only on secure joists or beams to avoid falling through the ceiling.

**What is the role of a vapor barrier in attic insulation?**

A vapor barrier is a layer of material (e.g., plastic sheeting) that prevents moisture from entering the insulation. It is typically installed on the warm side of the insulation (facing the living space) to prevent condensation from forming within the insulation.

What are the energy-saving benefits of proper attic insulation and ventilation?

Proper attic insulation and ventilation can significantly reduce energy costs by minimizing heat loss in winter and heat gain in summer. It also helps maintain a more comfortable and consistent temperature throughout the house.

**What are the different types of roof vents?**

Different types of roof vents include ridge vents, box vents, turbine vents, and static vents.

**What is the importance of proper roof ventilation, and how does it affect the lifespan of the roof and prevent moisture problems?**

Proper roof ventilation is crucial for: Extending the lifespan of the roof: It prevents moisture buildup that can lead to rot and deterioration of roofing materials. Preventing ice dams: In winter, proper ventilation helps maintain a consistent roof temperature, reducing the risk of ice dams forming at the eaves. Improving energy efficiency: In summer, ventilation helps release trapped heat, reducing the load on the air conditioning system.

**What are the signs of inadequate roof ventilation?**

Signs of inadequate roof ventilation include: Mold growth in the attic: Indicates excess moisture. Premature aging of roofing materials: Curling or cracking shingles can be a sign of heat and moisture damage. Ice dams in winter: A clear indicator of poor ventilation. High energy bills: Inadequate ventilation can lead to increased cooling costs in summer.
