    Ignorant homeowner requesting guidance - bad install, what next?

    Hello friends -

    I'm a homeowner who made the unfortunate mistake of hiring a "friend of a friend" to install a new central air conditioning system. Several thousand dollars later, it is not cooling as well as the 20 year-old unit it replaced. In the future, I will always use a reputable business (with trucks, advertising NATE certification, etc), but for now, I would like to ask the community's advice on what I should do next. I very little money left to get this right.


    Here is a brief summary of the installation:

    - House is 2700 SF, located in Austin, Texas

    - 5 ton compressor outside, vertical furnace and coil above in the garage closet

    - Hard duct with returns in the crawl space (existing, did not replace)

    - New equipment is Heil R410A- 16 SEER, two-stage outside unit with Copeland scroll compressor (model DXT+), Furnace is 80% efficiency (model H8MPV), Coil is also Heil. The guy who installed the new system highly recommended Heil mainly because he was supposedly familiar with their equipment and could pick it up from a local distributed.

    - Stat is Honeywell TH8000 series touch screen with humidification

    An here is whatI am experiencing:

    - Air is cool, not cold - only able to make house 20 degrees cooler than outside (95 outside, 75 inside at best)

    - Air feels damp

    - System seems to run 24/7

    - Just change the filter for the first time and noticed it was soaked with water and water appears to be accumulating near the coil


    The guy who installed it came back for a half day but say it's beyond his skills to get it working right. Could be a bad coil, compressor, or something in between. My wife is angry at me for being such a numskull, I am angry at the installer. Please tell me what to do.

    Thanks in advance.

    oops!

    Ok now you realize your error! Now your on better path, call in the pros.
    Ask for 90 day payout, confess what happen. you can find a contractor that
    will take a couple of payments..
    Could be something very simple. Time for second opinion. Find contractor that
    also sells the same brand [for warr parts if necessary.]
    Thats my best advice ..
    Please report back what is found and the cure.

    5 tons is more that enought for 2700 sq feet. Did you have a 5 ton system
    before. If not your duct work is to small. Do you have good airflow. What
    type of filter do you have, what is the MERV rating, if it is to high that
    may be restricting your airfow also.

    With your filter wet, either evap coil is not draining properly, or you have
    to low airflow, and coil is freezing up some, which will hinder performance.

    If you can post some pictures, that would help.

    I do believe you are going to have to call a pro in to help anyway.

    .

    OP:

    Don't hold your breath.

    You gave to good work away. Another contractor isn't going to want to wait for his money, for fixing someone else's crap install.

    Since you didn't post actual model numbers. We don't know that you have a 5 ton unit.
    You should always post the real model numbers, not just the model line numbers.

    Your going to have to pay for someone that knows what they are doing. And the majority of the time, that is not cheap.

    How many times must one fix something before it is fixed?

    I agree, 5 tons is probably a little bit oversized, but you never know the other factors involved....Sounds like, with the water issues, you may have a refrigerant leak (freezing up), or simply undercharged, maybe the blower isnt configured, maybe second stage compressor isnt wired up or configured at t'stat. When I hear about situations like these, it makes me smile, because of all the negative publicity we in the HVAC industry recieve. Chances are, Heil was used simply because that is the only brand the guy had access to. Should have paid a professional!!! Look in your local yellow pages and pay a contractor to look at your system you saved a few hundred dollars on. They will be happy to get you back on track again for a fair price. Any company I know of will work with you on paying, as long as you consistently pay on time without excuses....

    Search for local dealers at the Heil web site. You will have to pay for a service call, but that's life.

    20 degrees cooler than the outdoor temp. sounds pretty good to me.
    I don't know what you are expecting.
    Are you expecting it to be 70 inside on a 100 degree day?
