as a left handed adjustable (crescent) wrench...all my others have a right hand thread, this is the only one that has a left hand thread. threw me off when went to use it the other day, loosens when...
I have gear wrenches, bought a 1/4" one to add to set. used it same week to get 1/4" screws off a furnace. they were sandwiched between the j-box and return duct, 1" gap.
also have a rachet that...
after second look, that duct is between floors (flat trusses) so would be tricky to access. most flex does have the size written on side, but its amazing how on sucky systems the writing is...
heartland products dryer vent. they had a bathroom vent adapter kit to use it with bath fans as well. I bought mine through walmart, since lowes didn't have it.
pretty immune to blockage or being...
air will leak where the metal butts to wood, or between pieces of wood, or the joints where duct is assembled. so the duct seal needs to fill and coat over those places.
duct seal will adhere to...
people think the hole I drill to properly test equipment is an issue, but don't want me to seal the rest of duct joints which add up to a 6" round hole. people are funny like that.
seal the joints in ductwork, and where metal meets wood, that's where air is going to leak. no need to coat solid areas. I've also used it to seal down tape on duct insulation so it won't come loose.
that?
I must have been there:whistle:. I do that so can find the test hole easier.
I like duct seal myself. this one has some flex once sets up. can span over a gap with some tape and seal over top of it. 1/16-1/8" thickness is good.

yes, but comprssor was bad, so used to recovery machine to transfer the refer. have used the compressor for pump down on a hp if txv was bad or replacing condensor coil.
cop would be the refrigeration cycle.
I worked on one unit , not santa fe, which had a corrugated plastic layer in it, two air flows through the layers to act as a heat exchanger. I suppose the...
wow, that is high. only ever saw that high once before.
compressors have a coefficient of performance, for every watt of power consumed, can remove several watts of heat energy from air on evaporator (removes heat and condenses moisture) coil and then...
we're having to put auto-transformers on to bring the voltage down at the unit.
today I had to replace evap coil. put tool between filter dryer and txv in condensor, pumped down into condensor. switched out f/d inside condensor and evap coil inside without having to pull...
3/8" line, took over 45 minutes to get refer out unit. was hot inside and in 30's at night, no sump heater, so you know where it all migrated. checked air flow and had to adjust. may have had slight...
used it today. pinched off line next to filter dryer outside unit. closed suction line service valve, pumped refer into evap side. replaced compressor and filter dryer. opened line and suction valve...
I've got that style. have used to replace high psi switches on minisplits and heat pump units. great time saver, and don't have to open up the system.
also, have pinched off past the filter dryer...
I've used piece of metal (s-lock or drive cleat, look like long strip metal) to hold the insul mechanically in place. the glue nowadays isn't all that great. if the insul comes loose, could block air...
should be black iron, short nipple out tee for loop or wye fitting, too long nipple is issue on hartford loop tee. manufacturer should have had a diagram for the piping size they want. or like...
rubber hose isn't a permanent part of the house gas piping, either. it's only an appliance connector.
fwiw, rubber hose will break down if grease from grill drips on it, a common use for the...
It may have some setting for intelligent recovery, starts hp earlier when colder to hit setpoint at the set time. some tstats allow you to delay elec ht usage during recovery from the setback temp....
didn't think a 15 seer was variable compressor.
I suppose you're referring to the blower motor having speed ramping, off delays? That aspect is set at the air handler unit.
longer run times at night, so if breaker has wire loose or weak connection to buss bar, will heat up more and trip, my theorey anyway.
If it weren't for the "woke" and other foolishness going around now, I'd say good idea.
I've heard blast tube as older term for burner tube. have seen two so far this years that end cone/turbulator was burned and tube right at cone was also heat damaged. so you could call it "rot" I...
multiple 125 tanks can replace a 500 gallon, and do not have the clearance requirements or a single 500.
elec heat can be disabled with a regular toggle switch, have done so with other customers...
a "desuperheater" on a standard ht pump would do it.
the first pic, broken parts of metal are dark, so may have been cracked already.
being next to an open louver, wonder if the plug valve froze?
on a boiler, they're pressure only. water heaters have temp and psi. does make sense, though.
not sure why on water htrs, the valves are oriented side ways or vertical, but on boilers they're all...
office wants us to take pics and send to shop that we put stickers on units. sent a text saying "noobs, old school sticker on this one, been haunting this cellar for 17 yrs". was old one that most...
you spray burning gasoline with afff and it stays out. batteries will relight for days after, they're a delta fire (flammable metal) vs a b (flammable liquid) fire. the energy content of the burning...
with this ev stuff getting lots of press, and even semis and tractor/trailers, this came to mind last week. one of these with lithium batteries. co-worker who drives one, yeah thta's scary, what...
is that plastic wire loom in the bx connector?
yeah, i'd just cut the insulation and glue/tape the longitudinal seam. the pipe may start to drip further down, since air inside is warming some as passes through pipe. the exposed section will now...
I have run into units where the minimum heating airflow was too high for ac.
ie, 800cfm for cooling, but 1100 min for elec ht. I added a relay to allow two speed airflow, since a lower speed was...
I'd just wipe the wires off with disinfecting cleaner, get rid of the dirt that feeds whatever, assuming it wasn't just dirt. also wipe down/spray interior unit.
would put light on incoming side...
could have the wrong serial number applied to warranty , or wrong customer. had that happen with a generator one time, was already registered to another person, but was never out crate.
haven't...
I had to look a second time before I noticed the pipe out top of tee. yeah, the air sucking in (blowing in from coil)would cause flooded hx header and shut off the furnace pressure switch and it...
third pic looks like holes in the rusted seam, top pipe about 1/3 way down. if you poked the pipe with tool would probably break through. have seen it number of times, seams rust through before rest...
yep, my bad, cw vs ccw. saw the tap on left side of valve, looks like 1/4 turn type valve
the valve has a stop, can't imagine you were pushing it the wrong way? would have to turn it ccw to operate it, assuming the section under the square is one part.
I expected to see a valve wheel...
may want to put di-electric grese on/in the wire harness connections as well to keep moisture out the plugs and corrosion occuring there.
seen plenty of circuit breakers and contactors fail in units. air leakage around the breakers and wire/piping penetrations. sealing the cabinet helps, but did have a york unit that did same issue in...
I got the plug out blind, put it back in blind.....
service tech later told me the wiring got burned up, had stuck the plug in the wrong place on side of valve. felt like the hole but was a dimple...
oh man, the york valves buried in a corner, down in a hole, in a gas package unit. super hateful to access pressure port.
each company has its own policy. some systems are a nightmare to get blower out, some easy. some it isn't coming out unless you pull the system out wherever its jammed.
nordyne air handlers had a funny smell to them (insulation) . not sure why.
