    Compressor cuts out on high speed

    I'd like your thoughts on this problem. I have a Carrier 38TDB 4 ton with a two-stage compressor. It's been super hot here. In the afternoon, when the compressor tries to switch to high stage, it...

    Yes I'm sure you're right about using the right materials. I've finally figured out how my duct work was installed, and have looked at other houses under construction. Apparently the common way...

    Often the most leakage is at the supply boots. If the boots aren't sealed to the drywall ceiling you will have a lot of leakage there. It's relatively easy to seal all of these from the attic or...

    You might also consider a mini-dehumidifier. I got one for my master. I also have an exhaust fan, but the mini-dehumidifier is nice especially in winter, since it generates some heat, uses only 60...

    When you say you clean the coil, do you mean the outside unit or the indoor unit? When a tech says the "coil" is dirty, I believe he's usually referring to the indoor coil.

    120+ is not unusual. The amount of venting you describe is also common but may not be adequate. There are many ways to address your problem. I suggest ruling out obvious problems first. If the...

    Running two big dehumidifiers all the time uses a lot of electricity. I have a small portable Sears model that uses 500 watts. Are the dehumidifiers drawing in fresh air? If yes you may be...

    There are two-stage furnaces that have a high and low setting for the blower and the burners. Not the same as a variable speed blower. Variable speed is nice because it will automatically adjust to...

    The Halo brand has a sticker on the inside you can see if you remove the bulb and trim. It will say "IC" somewhere, like H7ICAT means 7 inch, IC, airtight. Not sure about other brands. The ICs are...

    Not an expert but I do live in Austin and commend your interest in an alternative design. Good luck with it. I would focus on humidity concerns. Austin doesn't get a lot of rain but don't let the...

    Jiffy Lube didn't change the oil filter

    Just before wifey left to get her oil changed, I whipped out a Sharpie and made a mark on the filter. Sure enough, she returns and the filter is untouched by human hands. She calls to complain,...

    The easiest way is with a caulk gun or a squeeze tube of caulk. Mastic comes in a caulk tube. Really any kind of caulk will work.

    If your problem is leakage, you need to remove the registers and caulk the gap between the drywall and the boot. Caulking around the registers won't do anything.

    That's a shame. Looks like a clever design. The bathroom fans should have their own dampers, so the damper at the wall is a backup of sorts. You should be okay with a regular vent. I glued a...

    Mine look like that. Six year old Carrier evaps in a humid climate. It may be galvanic action caused by dissimilar metals touching, or ordinary rust. Doesn't seem to be a big deal. Painting them...

    A portable AC might work, if you have a window. The AC sits inside the room and a tube attaches to a flat panel that fits in the bottom of the window. You hardly notice the panel from outside.
