Looking at lines I guess a 3 tons if it was a 4 ton the vapor lines would be 7/8 OD and the model number would be YCJF48S41S1
Looks like a York YCJF36S41S1
The first thing I always do before starting to work on anything commercial is ask the manager what been going on. When did it stop cooling? When was the last time it was work on, and what was done to...
I will pass this along to him.
Yeah, thought of that, but the customer thinks he's engineer. You probably know what mean by that.
The customer is complaining about the door pulling in when the system comes on. Does anyone have a formula for calculating return air through a louver door? The gap between each louver is 1/4 inch...
Thanks! Last I heard he's complaining to GC. I just hope leave me out this.
I'm going to get the model and serial numbers and check on register the equipment, but in Texas small claims court is joke.
I got a friend that is complaining to me about the air conditioning system in his new house in Florida to me. He said the contractor is license, but won't come out and check the system. He said they...
I love the smell of cutting duct board in the morning!
They use the old RTU return just to get the refrigerant lines into the building. These are things that make you go hmmmm!
I didn't know you could cut into the TAM cabinet.
No I've never heard of refrigerant being stolen from unit, put I have heard of refrigerant valve locks stolen.
The next thing the environmentalist will be saying that CFC cause volcanoes to erupted.

I remember someone saying that if you put a higher or lower mfd capacitor than rated for the motor your amperage will go up. I never try it, but it makes sense.
Carrier test them before selling them, but they still had problems with compressor failure.
Carrier Corporation was the first company to introduce an R-410A-based residential air conditioning unit into the market in 1996 and holds the trademark "Puron".
I came across one leaking water once and when it was installed they forgot the coil support rails. We had robbed one from a damaged air handler at the parts house.
It could be a indoor air quality problem that is causing slime. I would recommend UV light in return air.
The genes your born with is large part of it and the way you look at life is the other part of it.
I turn 69 today and use to think everything in this business was going to kill me, but looking back on the past 47+ years in the HVACR business. I can tell all you techs and especially younger ones...
Maybe 20 years from now Thermoelectric cooling will replace refrigerants.
Something you don't see every day in handicapped parking spaces.
Several years ago I installed a York 5 ton package unit with a mirco channel condenser coil on a church and it would trip the HPS. I try several things and come to find out from York Tech support...
Thanks, I forgot it was a belt drive blower in that furnace.
I'm trying to find out can this old furnace move 7.5 tons of air. It did have a 7.5 slab evaporator coil on it.
The last York zone control board (4 zones) I did was about eight years ago with a bypass. Never had any problems.
If water comes out of the coil looking like chocolate milk, it would best to wash the coil inside and outside.
I never use coil cleaner on condenser coils, unless they are exposed to grease or oil. I only use water with light pressure (no pressure washer).
I haven't seen anything on 1040.
Which thermostat?
I am not sure, but I think this is what happened. The renter put some weak batteries in the thermostat. That Vivint needs a lot of power to work the display and lights. The thermostat needed power so...
I got a call to the rental property and it had a Vivint thermostat that was on cooling and the heat strips coming on at the same time. The renter told me they thought it may be time to change the...
Those valves mess up those a/c guys that think it was installed backward at the factory. lol
Some thermostats can read static pressures but only on communicating systems.
Down here in Texas if contractors make false claims about equipment being installed or the system doesn't work right. They can be fined by the state license bureau. Do they even have the required...
I'm a one-man show again and have been busy and haven't had time do much.
I would take a piece of copper tubing the same size as the pipe with the hole in it, split it and make a patch.
Welcome to the party!
Wouldn't pass here, the condenser has to be set 3 feet from the electric meter.
Damn, I bought my static probes.

They are all basically the same quality nowadays. A two-speed and variables will be better at taking humidity out and lowing electrical bills, but may be more complicated to you have never worked on...
I really don't have that problem. I'm in better shape than when I was 40. I run about 6 to 7 miles three times a week. I run 5k races and still ride my motorcycle. If the weather is bad I go to gym...
