Homeowner Questions

COMMENTARY

• David updates the cost of a Home Energy Audit and the details the audit provides on your home
• Discussion on need and specs for freon coolant

CALLER

• Deborah asks how do they inspect a home with a flat roof and a high ceiling. No attic like a pitched roof. And how does she know if there’s insulation in the walls or in the ceiling where you can’t see anything.  David explains using the thermal camera which allows them to find any heat gain behind walls and ceiling. Also we look at her energy bill based on square footage and highest summer bill

CALLER

• Roger has a couple of 10 inch steel pipes/duct in the garage going up to the attic for the furnace. He wrapped them in silver bubble wrap. Any other suggestion to cover it

Air Filters & Homeowner Question

CALLER

• Mark has a 1948 solid brick Hallcraft single story home in Tempe. Added a new two story 1200 square foot addition. The addition is a sealed envelope with foam attic and its own A/C. The original home is still a vented attic with its own A/C. Summer bills are around $600. Thinks his bill is too high and a home energy audit might show some deficiencies
• Change your air filters regularly for ultimate A/C efficiency
