@ June 23, 2013 6:35 PM in freezing evap coilIs not the problem. Check for blocked dryer or bad TEV.
@ June 23, 2013 6:31 PM in 6" Boiler Exhaust w/ 5" chimney liner. how bad is this?In DC. It was a 7" down to 6" and was reduced right at chimney. Had a passed sticker on it.

@ June 15, 2013 7:53 PM in High subcoolProbely have a bad TEV and someone dumped a lot of gas in it to bring up the suction pressure.
@ June 15, 2013 3:32 PM in Boiler hot, 2 zones, both thermostats turned "Off"In the house getting hot? The way things should happen is Tstat calls and zone vavle opens. Zone valve end switch closes and send signal to boiler, boiler tells vent damper to open once damper fully open spark ign starts and boiler fires or if standing pilot gas valve opens when damper fully opens. If you have a standing pilot it may be that its generating enough heat with the damper closed to warm the top of the boiler and pipes.
@ May 5, 2013 7:55 PM in Suction line frosting??To differ. A properly charged and running A/C system with no low ambient control running at out door temps at 70* F or below will most definitley have bubbles in the SG.
@ May 5, 2013 7:46 PM in Suction line frosting??You assume 10*f super heat when the system is not performing properly?
@ May 3, 2013 5:01 PM in What the best leak detector for r410aThat I would get a little more chatter on this subject but be that as it may, I told my troubles to the good folks at Inficon and they sent me a replacement cell and new battery free of charge. I will let you know if the results are better, the battery is a upgrade, not the same as what came with my leak detector.
@ May 3, 2013 11:10 AM in Suction line frosting??Will go to where the pressure is lowest. Usually the coldest spot.
@ May 3, 2013 11:07 AM in Suction line frosting??Pressure control to cycle the condenser fan is enough for your issue. I doubt you will run the unit over night during cooler weather. Hard start is also a good idea. Another way is whats called a motor master control which slows down the fan instead of a on off type but they are much more expensive. Is it possible the people in the other area are cold and shut their air flow off? You could have up to a 4-5# pressure drop in 40 ' of line. Which means your coil could be clear but your lines at the compressor frosted. Was it frost or ice.
@ May 3, 2013 8:22 AM in ideal temp to check A/CTo block the outdoor coil inlet. Not really do-able with the top dischars units. Worked ok in the old side discharge days.
@ May 3, 2013 8:18 AM in Suction line frosting??Is the piping run? I think 70* outdoor is a little low to run a A/C unit all day long with out any low ambient controls. Does this unit serve only your office or others as well? Never assume the filters is clean, never.
@ May 3, 2013 8:07 AM in insulating type B vent pipeWe have the 1 1/2 times rule which means you can run 6" vent 9' horizonal and 4"
6' h. So seems to be your way over the max and it should have never passed
@ May 3, 2013 7:55 AM in Suggestions for frustrated and confused homeownerDo with the body of the electrocuted plumber?
@ May 2, 2013 8:35 AM in ideal temp to check A/CThe grass is still wet with dew on account of it being 70% rh and my kness get wet. Not really ideal, unless it's late in the afternoon and the unit is on the southside of the house and we have a breeze.
@ May 1, 2013 10:31 PM in Question regarding boiler sizing and IDWThe 110 turns down to 30K his stated load was 57k. I personally think the TT60's are to small for a quick recovery on your indirect.
@ May 1, 2013 10:15 PM in ideal temp to check A/CSo that would be 92*f @ 70%rh. Thank you and good night.
@ May 1, 2013 11:23 AM in Question regarding boiler sizing and IDWThe triangle Tube 110. That will heat the ID quickly and and keep you nice and cozy.
@ May 1, 2013 10:53 AM in subcoolSight glass on start up, on a hot day with a big load on the evap you are over charged. I don't normally use a sight glass on A/C mostly refrig. systems. I chagre to sub cool after a pull down and the evap tep at or less then 40* F. So there you have it 9 different ways and they all work.
