Intertherm Heating and Air system
Posted: Tue Feb 04, 2014 3:30 pm
Coming from the marine field I have very little experience H/A systems in mobile homes.
I have 2 questions.
1. Last summer at night from the master bedroom we kept hearing a ticking, kind of like water dripping. We concluded it was from the vent register in master bath. It was when the air was on and it slowly stop after the air cut off. I could not find anything obvious so we turned off the a/c at night.
Now we have a tapping noise in the dinning room coming from the vent on the floor, only when the heater is running. It sounds like someone dropping nails or screws on the deck. After the heater cuts off the noise stops. No noise from the heater in the master bath or in the dinning room from the a/c.
The ducts are sheet metal and about 14"x 6" (just guessing) they run the full length of each side of the house with cut outs for the floor registers, I do not see any flexible ducts under the house and the sheet metal duct is covered by the insulation and vapor barrier.
I tried running the fan for 2 hours everything was quiet , I think it has something to do with expanding and contracting.
Any body have any solutions to this problem or am I the only one experiencing this?
Question 2
We have vent type registers in the ceiling, 1 in each bedroom a larger one in the hallway and 1 in the living room. The air conditioning guy said they for speakers, can you believe that, I politely told him to leave.
I have turned on the system removed the grill covers no air enters or leaves these vents, I used a candle to determine this, they do have flexible ducts on them.
Anybody have any idea what they might be for, also we have no access panels to the roof above the ceiling for further inspections. Oh yea for got they 9" in diameter.
Thanks
Jim
