    Carrier Installation

    Doubt that the float switch will work as intended. Also looks like someone forgot something when installing the air handler...

    I talked to one of the installers as he was getting ready to finish up on another home in the development. He was hooking up his vacuum pump so I casually asked him if he had to get down to 500 microns and his answer was "no, we just go down to 30-in or so because this is a new system". Yikes!

    How does that non-trap pass the building inspection? Is there no duct testing for new homes?

    I wondered about that myself but then I realized that the run itself is the "trap" because it is routed down and under the slab and then back up above ground outside.

    Yes, Florida - forgot to mention that little tidbit. Below is a sketch of the run with the trap partially inside and partially outside.

    Mine neither. Drain pan has cracked before, but never a stopped up drain and I never cleaned it out. Funny how that works.

    Im in Florida, 90% of the drains are run like that. They usually work, but it can be challenging.

    What air filters do you use? Filter grilles or rack at the furnace?

    In my area, new construction is paying by piece work. No nitrogen, no checking pressures or temperatures, just how many units can be installed in one day.

    I need to clarify this...

    I was referring to new construction... sorry for not noting that.

    In new construction... it is all piece-pay...
    And very little follow up...

    It's such a disservice to the people who end up with these poorly installed systems though, and it gives the industry and the equipment manufacturer [where homeowners usually place the blame] a bad reputation in general.

    It's not uncommon to see the installer's service vehicles at homes less than a year or so old, sometimes making multiple visits to fix problems, and often running around with a torch...

    Yes but doesn't the quality of the house match the quality of the HVAC installation? Usually these get done fast and cheap builders are the worst quality. There was a house built in my area that the stairs coming off the deck behind the house were not even straight/didn't fit. They should have been an inch or two shorter to straighten them out, you could see it from the street. If there are things that obvious how much is hidden?

    Granite countertops and black SS appliances sell a house...
    Few seems to care about quality...

    They want glitz and glamor...

    Then they learn the hard way...
    Yet they go back and do it again when they buy their next house.

    We as a society have flunked the prosperity test...
    We have lost consciousness of what value is...

    Sadly... history teaches us: re-learning the lesson, comes with pain.
