I have two 4-ton units in a house that was built in 1959. It's 98 degrees outside right now, and on one side of the house (west side) the vents are blowing out at 64-65 degrees and other side of the house (east side) is blowing at 68 degrees. Do I have a problem or can this be expected?
The energy cost of exhaust-only or natural ventilation versus energy recovery ventilation can be easily demonstrated. Take a 2,500-square-foot house with indoor conditions of 70Â°F and 40% relative humidity, and outside air conditions of 30Â°F and 50% relative humidity.Heating season function shown by flow arrows.). A closeup of the air-to-air heat exchanger core. The heat recovery ventilator (HRV) and its close cousin, the energy recovery ventilator (ERV), can often make a home more efficient.
