HVAC SYSTEM ASHP York 3.5 Ton 2011 Pressure Pan Readings Duct Leakage Results 0.7-1.5 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 only 5 years old, no need to replace. Post Images Marshall Insulation 2 P age
ROOM PRESSURE TESTING Room Pressure Testing/Total Rooms 2 1. Master bedroom 10.5 2. Spare room 8.9 3. Spare room 12.6 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. Marshall Insulation 3 P age
