Its worse than that. There is no TXV. It has 16 individual feeder tubes, each with its own orifice. Trane tech support says the statics are too low, that we should have 1.5 ESP. There are 2...

OK guys I know this is simple, but my brain is frazzled and I need a fresh perspective.

We replaced a 10 ton compressor 2 weeks ago. After the install we had perfect superheat and pressures. Now,...

Hello

We are having issues with a 15 ton Trane RTU. The model # YCD181****ABA. We are hosing down the outdoor coil every 3 weeks. I read a thread months ago about splitting the coil to clean it....

I had the same problem about 2 years ago with a 15 ton RTU. Trane would not offer any help. We replaced the entire indoor coil because 2 out of 16 feeders were icing up. Your situation sounds like a...

Hello Folks,

Does anyone know where I can locate Aspen coil performance data charts matched up with Ruud equipment? I need the chart that shows ambient temps through 115 degrees, with various...

This system has given us a lot of trouble. We replaced the indoor coil last year because 2 of the 16 metering orifices became clogged. The compressor that failed was constantly struggling to maintain...

This is an RTU. The first failure was an acid burnout. Knowing the company that was doing the maintanance, I presumed it was due to sloppy technicians introducing contaminates into the system.

The...

We replaced this compressor 2 years ago. Did everything by the book. We even installed a suction line filter drier that we replaced every 3 days for 2 weeks to make sure no acid was in the system. It...

Hey Guys,

I am a small HVAC shop in the Palm Springs-Indio, CA area. I am in need of an experienced technician and installer. I do not require a lot of experience. I actually prefer guys with less...

Apparently this has been a problem for 2 years. It is a rental. Another company put in a new 4 ton condenser about 5 years ago, but left the original e. coil from 1979. They also tapped 12" ducts...

Apparently this is where I made my mistake. I sized it to 1800 cfm, assuming .5 iwc static. We used 14 x 6 cans w/7" flex and 14 x 8 cans w/8" flex. How do you recommend I fix this without re-ducting...

Don't mean to be a smart ass, but if it did, I wouldn't be here discussing this, and there would be no need for a re-duct:cool:

sounds like your overcharged or the TXV is stuck closed. This is not a leak. To bring the temps between the liquid line and the condensation temp closer together (10-15 degrees) the pressure must go...

4 ton condensor, 5 ton e. coil, 4 ton air handler with 5 ton blower wheel/motor upgrade.

Hello fellow HVACer's,

I think I'm in over my head on this one. I re-ducted a mobile home with flex duct to get better air flow to each room. It is much better, but not good enough. We installed a...

That sounds like a good approach since I'm dumb founded at this point. But won't reducing the main supply trunk increase my statics?

7" & 8", with a couple of 5" thrown in for the bathrooms

His expectations are reasonable. The home will not cool below 84. I've looked at more modern M/H's, and they seem to have the same airflow...

Yes

Yes we ran an 18" trunk to a supply plenum in the middle of the home so all of the ducts are of equal length to their terminations.

The old smaller registers were not moving enough air to compete...

The home is a double wide, about 1500 sq. ft. I reducted with R-6 flex duct, removing the old and many 10 x 4 floor cans and replaced these with either 14 x 8 x 8 or 10 x 10 x 8, depending on free...

When the unit is in high speed it does not have any return pressure at all. High amp draw, no air flow. A piece of paper won't even stay against the return grill. The guys at Nordyne admit that they...

Hello

I am a contractor in S. Cali. I recently looked into a product that you can leave in a customers home for a few days and it will provide scientific air testing results about humidity, radon,...

Does anyone know a formula for figuring out the sensible btu's if the outdoor ambient temp is 115 F. I used a load calc program for a job, but all data for residential coils is rated for 95. I need...
