Hi all
I need some help / advice on what to do.
I have a 1600 sq/ft home and just had a York air conditioner installed, both air handler and compressor – model numbers - AE36BX21D / YCG36B21SA.
My old system was 19 years old and was on its last legs – not very cold. The air handler is installed in the garage (in Florida). Compressor on the side of the house.
After they installed everything I was amazed at how cold the A/C was and how quickly it cooled down the house.
Problems:
1. They did not change the breaker to the correct amperage for the compressor – it was a 40 amp and should be a 35 amp – I changed it myself and everything is working.
2. There is a quite a bit of condensations (sweat) on the air handler in the garage – the inside of the unit does have insulation but they did not seal any entry pipes into the unit or seal any electrical wires entering the unit. Could this be a cause of the condensation? I know that any cold metal in contact with humid air will cause condensation. My older 19 year old unit used to do the same until I insulated the inside of the unit and taped up the seams on the outside. My friends also have newer units and theirs are bone dry – also located in the garage.
Is this typical of a York unit or is there something else that can be done?
The problem is that the unit is on a stand (wood) and it will eventually rot the wood and cause mold.
3. The air intake (filter) for the unit is on the same wall as the air handler (living room floor) – the filter size is 24x20. When operating I find that the air flow is loud. I can hear it from all the bedrooms, regardless of whether I open the grate and remove the filter or not. My older unit was much quieter. Granted this is a new unit and a lot more powerful but I checked my neighbor’s unit (carrier) and it was so quiet. He has the same size house and the physical size of his air handler is bigger than mine.
I also timed how long the unit stays off after reaching the set temperature – between 5 and 8 minutes. Regardless of temperature or time of day.
Insulation in the attic is at least R19
I do not have any returns from anywhere in the house other than the main return in the living room.
The plenum (duct) from the air handler goes into a junction box in the attic (about 12.5 x 12.5 inches) and then has 2 ducts running to other junction boxes for the rest of the house (other boxes are smaller).
Can the blower motor on the York air handler be slowed down to reduce noise? Will increasing size of first junctions box help? How can I reduce the air flow noise into the air handler?
Is this system too powerful for my house? Should I switch it out with something else?
I want to find out all this information before contacting the installer.
I tried calling some AC techs in my area and no one was willing to discuss or help because they did not do the install.
Any help would be greatly appreciated.
