Lennox Air conditioner in the Attic
WARNING MIGHT NOT BE THE CORRECT PLACE TO POST BUT HERE GOES
HI,
I live in Montreal, Canada and over 15yrs ago installed a Lennox Air conditioner in the Attic with the main ducts and flexible duct. The heat/compress is outside and the coil is in the attic. All the Returns and vents are from the ceiling, all the ducting either fixed/metal or flexible ducting is insulated at the time.
What I’ve observed is the following
Attic Temp Vent Air
25C 13C
37C 18C
50C 21C
wondering if this is normal?
Alberto

How close to the return and discharge do I need to be? The unit is in the attic, is there a easy way with Lennox Machines to get a reading of the temperature at the return and discharge without having to physically climb into the attic?

Take temp reading at a return grille and at the supply register. That will get you close and save a trip to the attic.

It's only a Air conditioner Unit and not a Heat pump.
The readings I took them back on July 4th we had a very hot stretch. I have a thermometer in the attic and a thermometer to measure at the supply vent in my room.
Yesterday it hit 30C in montreal but only turned on the AC unit end of day, i took the following small TWO SAMPLES sample
6:00pm
Attic Temp 37C
REturn/Discharge 25.9C
Supply 18C
10:00pm
Attic Temp 27C
REturn/Discharge 25.9c
Supply 16C
