Thread: Legit excuse?

  1. #1

    Legit excuse?

    We live in an apartment complex, and the AC just plain sucks. Our management says its because we live on the 2nd floor.

    During the day it peaks at about 80 degrees inside and doesn't dip below 72 at night so the unit is constantly running.

    Only solutions they offer is to close vents in other rooms. The air that comes out is cold, but you nearly have to put your hand against the vent to feel the blowing air. They keep telling is the unit is fine and working normally. Even the fact that the air handler shakes and knocks, they says its fine.

    Our electric bill says different, along with the daytime sweats. Any ideas?

    No matter what Management says, it's not even close to right. Have they had a qualified service technician (not a hack) look at it?

    Apartment = dirty evap coil.

    It's their in-house techs so they claim they're are real techs.


    They've also said they've cleaned the coil

    The way apartment maintenance techs clean a coil is they clean the front surface and the rest of the coil is impacted with crap ,then they put a thermometer in the duct and have a big delta t and think they acomplished somthing due to the lw output temerature .ill bet the blower wheel and coil are all clogged up
    We really need change now

    You may have to pay out of pocket to get it fixed right, the property management will not pay to fix anything right just cheap in most cases. It's either pay a tech to fix it or pay the power company every month

    You said they cleaned to coil. Were you there, should have been obvious they were cleaning the evap. Ahu is in the closet?

    What catmanacman said is sadly so true. The last apartment I lived in was after I left the apt. maintenance field. Shortly after moving in it was obvious to me the a/c was not up to par...kept the place marginally cool but did not dehumidify well. This was a downstairs apartment, with only two windows and two doors. I could have called on-site maintenance, but knew it would be faster to just resolve it myself. Long story short...blower wheels filthy, evap coil filthy, system overcharged. Cleaned everything and recovered the refrigerant. Place was mighty comfy after that.

    In your case it's likely the same thing...dirty indoor unit (the knocking could be from blower wheels out of balance) and possibly overcharged (that happens when someone comes to check it and goes by reading gauge pressures only. He sees low pressure and adds refrigerant, not realizing the dirty coil is responsible for the low pressures, not a loss of refrigerant). The end result is insult was added to injury.

    Ever notice how many condensing units an apartment complex chews through in a year? Give me almost any complex approaching five years old and count how many original condensers are still there. Not a lot.

    • Refrigeration makes the HVAC psychrometric process happen.
    • HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.

    Actually, I live in a large apartment complex and I'm always surprised at how many orginal condensing unit there still are. They must have built them tough back then. I know they do not maintain them at all. When I moved in I had to clean everything inside and out and then recharge.

    What brand was originally installed at your place?

    You may also have a shorter cooling season than we do here in TX. The complex I referred to in my last post did have a lot of the original Trane condensers (from 1989) left...those "Climatuff" recips are pretty hard to kill, apparently. Other complexes I've seen go through condensers pretty quick...variables vary as to how long they'll last.

    Goodman "Janitrol" 26 years old. I'd say about 75% of them are still left. I havn't checked, but I'm sure you have a longer & harder cooling season that us, but still, you should have seen how much dirt I washed out of that condenser. I know the rest of them are the same way.
