there's a more expensive pump that you can hide in behind the indoor unit

taht temperature isnt really overheating, i've never repair a windows ac before, why do you think that temperature is overheat, what I consider overheat is when it's too hot to touch the compressor....

the high pressure is okay if it's hot, well it's hot at miami. Your thermostat is set to 56 degree, it shouldn't frost at all imo. Check your thermostat, see if it's working properly, check the...

these mini split AC has a lockout system on the board, that if the high pressure switch trips, more than once in a 24 hr period, it will lock out the outdoor and indoor unit, even if you try to turn...

i hope you did not put in a R22 compressor, even you did put in a R410 compressor, the compressor probably took a great hit of damage by now

the purpose of the solenoid valve is to just let the refrigerant flow. I have not look into the mechanical part of split ac, but they should work the same as all refrigeration systems. So if the...

Both, btw why does ur profile said hvac engineer? :)

solenoid valve opens when there's a call for cool, and high pressure switch trips when the discharge pressure is too high, the reason it they're in series is so that if the high pressure switch...

yea, the super heat is very high for a freezer, you have the doors open the whole time or something? did you measure it at a steady state? And yes for a freezer, you should see little frost build up...

like all others said, what exactly do you want to do? Having a duct going through the roof on the bottom of the unit is already sufficient for air flow. Are you saying that you need an extra duct on...

shows the freezer uses 1/3 HP compressor, what's the new compressor you put in, 1/4 hp is a little under sized imo

What tools do you guys use, specifically to measure the line temperature? I've seen those tool that can measure the pressure at the valve, and the clamp tool to measure the line temperature, but was...

what model is your AC, outdoor units should have contactors to control the compressor. If you say there's one contactor in 1, and not in the other, that means your INDOOR UNIT is also different. So...

It's harder to convince residential customers to pay that amount for their appliance to be fix, and they usually ask several technicians before having it service. As for commercial places, the owner...

AmeriCooler is good walkin. Although I've hit the lottery twice with AmeriCooler, they gave me a wrong Panel twice when I installed their walk ins, you know the hook is on the right side, but upside...

for these simple pump down systems, like walk in boxes, remote cooler/freezer, what are your typical settings for Cut In, and Cut Out, let say for a r134a, 1/3 HP, high temp compressor, with less...

depending on what you like to do, but if the wages of the sales vs technician aren't much of a difference that they offered, i would prefer to work as sales, less hard manual work involved

just wondering if anyone any good place around NYC area that sells GOOD quality dumbwaiter (food elevator) cable, the one that I got from my local electrical store tend to worn off easily.

here in NYC, many small restaurants buy Leader brand, which is crap, sometimes they undersized the compressor, and soemtimes they don't leave room for the condenser to cool, like those beer coolers...

what do you guys think of Beverage Air

thanks for the help guys, if it fails again next time, i'll make sure i go through a detail diagnose.

currently servicing this ice machine, it's new, 3 months old. The machine stops making ice and BEEPS TWICE. The problem is due to long harvest cycle, because there's a big slab of ice in the ice...

what's the information on the condenser unit, what's the high pressure at the time it cuts off, is there any high pressure cutoff?, need more infos

yea, make sure the base are flat, and all the panels are aligned, if one panel came up just a CM higher or shorter than the other one, u will have a hard time securing all the panels.

we do installation and maintenance of hvac, most painful task would be talking to the customers you are repairing the units, tellign them this is how much they need to pay, CONVINCE THEM, or else you...

i can only think of the start switch is staying on for too long to pop the start capacitor

any brand thermostat generally last for long long time, unless you get those with touch screen, which the screen might not last long. I just use the cheapest thermostat there is.

okay, make sure you are looking at the right PCB, there's one at the burner assembly, if that work has a steady blink, then it's working fine, according to what you say, it might not be ignition...

i don't believe this is the installer's fault, it's probably customers couldn't pay enough to get it done the right away, they want it cheap right, so they have it

well, it's working right? that's all that matters :)

if the CO alarm goes off, that little bathroom vent won't do you much by staying on, yes get out of the house.

Fujitsu mini split system, very good quality, reasonable price, Mitsubishi or LG are a little overprice

the flame sensor needs to get very hot in order to allow the gas valve to open for main flame, here's the two things that usually solve the problem, most of the time, gas pressure doesn't come into...

correct me if i am wrong, but if the disconnect is inserted, then it will automatically trip the breaker since the White wire is grounded at the unit. Assuming there's not flame spot around the...

most unlikely, rooftop units has many limits that can prevent compressor failure, even if you can get a call for cooling on the thermostat, the rooftop unit has several limits that can prevent the...

give out business cards to restaurants and people you know that can help. I will stay away from newspaper and ads for now unless YOUR company does big installation jobs. For general maintenance and...

I agree with the guys above, when i get a service call, I always always go on the site to take a look. I will not agree with what the customer said, if he say it's compressor burnout and give me all...

My father is an HVACR technician, and I started to follow him to work for few years now. We do installation work mostly for restaurants and residential places. Some works that we do are, install all...

ouch, did you happen to get a new one from the supplier free of charge?

i would do the following steps in order:
1) check proper refrigerant charge, if correct go to next
2) check defrost heating element, if good, next
3) check timer, see if it's stuck on...

tell them the freezer isn't even going to freeze stuff with that much of ice at the coil, it's not even freezing at this point. If you really can't turn it off, what i would do is chisel off the big...

it's a very very rare case, even if the lines are not properly secured to the wall or other stuff around, the vibration shouldn't be strong enough to cause such an abrasion from over time. I would...

1) RLA is closed to the FLA, but not the same, RLA is usually a rating given by the manufacturer of the ampere the compressor should run, and FLA is the maximum ampere the compressor should be...
