2 HVAC SYSTEM ASHP Rheem 3 Ton 1979 Pressure Pan Readings Duct Leakage Results pa 740 No Mastic on ducts Visible leakage Why is this important? As much as 1/3 of your home's expensive conditioned air may be leaking into or being pulled from to the attic or other unwanted areas through cracks or poorly fitting duct connections. In addition, to increasing utility bills, indoor air may be contaminated with pollen, exhaust fumes, or other hazards. Pressure pan readings under negative pressure should be less than 1.0pa.. Recommendations: 1. Seal ducts with Mastic and test for leakage 2. AC unit is over 20 years old, need to replace. Marshall Insulation 2 P age

3 ROOM PRESSURE TESTING Room Pressure Testing/Total Rooms 2 1. Master bedroom Spare room 10.7 Why is this important? High room pressures (greater than +/- 3 Pa) do not allow for air to mix and exchange, causing the unit to run longer and increasing occupant discomfort due to uneven air temperatures. Additional Notes: These high or negative room pressures are only a concern if the bedroom doors are kept closed for any period of time. Recommendations: 1. Keep all doors open or install In Door Passive Vents to balance home. If needed Marshall Can provide and or install these items. ATTIC FLOOR INSULATION Marshall Insulation 3 P age

4 For insulation to be effective, it must be in 100% contact with the air barrier, no gaps, voids, or compressions. A ½ gap in the air barrier reduces the R-value by 75%. Total Attic Square Footage: 1210 Insulation type: Blown in fiberglass Average Depth: 5 inches Overall Installation quality: Effective R-value: Description: Customer has very little insulation in the attic and it needs to be upgraded to R38. Recommendations: Upgrade insulation to R38 CFM50 Blower Door Infiltration Test was pa negative pressure. Air Changes per hour ACH@50 was 15.0 Marshall Insulation 4 P age

5 Recommendations 1. Replace front and rear doors/ visible leakage- 2. Replace windows only single pane windows, one window is completely broke. 3. Seal all attic penetrations on the ceiling floor. Why is this important? Your home needs to breathe to be healthy. Too much leakage brings contaminants into the home, and increases CFM50 while too little leakage does not allow healthy air exchange with the outside. SAFETY-COMBUSTABLE APPLIANCES Marshall Insulation 5 P age

6 Why is it important? A large negative pressure inside the home will pull carbon monoxide and other toxins from combustion appliances and the garage. Unsafe water heater placement can be a potential fire danger and can cause other serious dangers. Recommendations: 1. Keep all Flammable Items away from Water Heater. 2. Water heater is 4 years old, no need to replace. WINDOWS Existing Windows = Single Pane Windows that demonstrate high leakage. Marshall Insulation 6 P age

8 Why is this important? With 300+ days of sunshine a year, homes in Phoenix are exposed with large amounts of radiant energy from the sun. Windows are a large source of air conditioning load along with causing considerable comfort issues. Shade screens can reduce the sun s rays by 80-90%. Recommendations: N/A 1. Customer has new shade screens. 2. Replace windows if possible- Marshall Insulation 8 P age

9 Abbreviations: CFM50= Cubic Feet per minute air leakage at 50pa negative pressure. Air Changes per 50pa negative pressure Additional Items to be addressed: 1. Need to paint the addition with fresh paint. Marshall Insulation 9 P age
