I Will Say This About Hillary….

She should consider herself very lucky that she is running against Trump….

Cruz, Rubio…… even Jeb……. If that cheeto toned clown had not bashed all the decent people out of the way….. I believe Hillary would be in a fight for her life in this race….

Everyone was quick to dump Cruz….. I just dont get it….

Windows A/Cs with automatic (not manual) dehumidification?

Does there exist a window or portable A/C that will go into dehumidify while in cooling mode if the compressor is not running? The units I have seen have a separate dehumidify mode which then precludes cooling and vice versa. I want one that will dry the air if the a/c is slightly oversized, which causes the compressor to not run enough to dry the air.

TXV Woes

Ok I had a no cool call the other day that has been giving me trouble. I found a bad condenser fan motor and a dirty evaporator coil. Cleaned the coil and replaced the motor. Turned the unit on and it purred like a kitten. pressures where spot on. The unit was cooling great. I leave and go to two more calls, and the shop calls me and tells me the customer called and the unit quit cooling. I finish the call im on and head back over there the compressor wasn’t running. I ohm it out and all is good so I turn it on and it is running. I notice that the suction line is not sweating now and reach down and feel of it and the liquid line and they feel to be about the same temp. I go to the truck and get my gauges hook them up and I have a very low suction about 38# and the liquid line pressure is about 184# which was standing pressure for the current outdoor ambient of 96 degrees. next thing I know the compressor starts bypassing and then trips on overload. My first thought was a compressor valve issue. I cooled the compressor off tapped on the top of the compressor a bit and turned it back on. Pressures where the same so I jarred the condenser a little, and the pressures went back to normal. So now im definitely thinking compressor valves. I inform the customer that if it happens again we may have to replace the condenser since it is r22 unit. Another tech and a helper go out there a few days later and he checks to see if he can get it to pump down and he determines that the problem is a bad txv so he goes and gets an r22 valve and replaces it. This was friday and as far as i know the unit is still running. My problem is that I have never seen a closed down txv that didn’t have a high liquid line pressure an low suction and I havent seen one make the compressor over heat. Freeze the Evap. coil yes. and never one that would work intermittently. The liquid line pressure not changing is what led me to believe that the problem was the compressor and not the txv. Can someone explain to me what is going on. Thank you

Hanging very heavy carriage doors

Hi – I was lucky enough to find a great Amish builder who made me two pairs of solid mahogany carriage doors for my garage. Each opening is 8×7 and my contractor added additional studs for extra support. The builder estimates them at 130lbs each but it took 4 guys to get each door off the truck and I can barely lift a door a few inches.

My GC is a bit nervous about getting the install right since its hung on hinges that are lag bolted to the underlying structure. The frames aren’t perfectly square so he will need to do some shimming to get it just right. The issue is that he can’t shim the jambs because the lag screws go deep into the supporting frame. So I suggested that he build a temp support to hold the doors in the exact closed position he wants it and then use that to line up the hinges.

Anyone try anything like this before? Given the weight we are worried that they will shift a bit and then will be out of alignment. Or over time they will sag. The lags have a out a 1/32 of an inch of play within the hole of the hinge. Plus the hinges are mounted on the face of the building frame so he can’t shim it horizontally.

Kairak condensing units

Hey guys I have never worked with a Kairak condensing system before. Its a big condensing unit with like 3 compressors in it. two walk in coolers and a walk in freezer with some cook line equipment share this ‘rack’ system they call in here in TN. I replaced and expansion valve because of freezing up and low pressure. No luck with the new TXV I checked all 4 evaps in the walk in coolers and they all are running the same. about 0 deg saturation on suction and 90 deg on the head side.404A, Another complaint their having is the walk in freezer with 2 evaps is running about 20 deg. Ive asked my manager if the system could be low on charge he said no the receiver on the condenser is just over40 percent full. Anyone work on these before?

Poor sealing fridge door gasket.

Might there be a tradesman’s trick for getting aftermarket gaskets to seal properly. I have a fridge that I’m told had this gasket replaced about 5 years ago. Even at that time the gasket fit was as you see it in the attached images. They’ve made no previous attempt to get a better fit. I just looked at it and the installation looks proper — The gasket simply seems like it has no extension (accordion effect) at the two corners.

The poor seal caused much condensation both inside and out. Unfortunately this is taking its toll in the form of minor isolated corrosion (as seen in pic) along with a constant mildew problem. This Kenmore (#2539768481) is probably 12-15 years old and, while still in otherwise very good condition, I’m not sure investing in a $100+ genuine gasket is worth it.

Any tricks-of-the-trade appreciated.
