I did a repair today on a carrier brown round from 87 and it brought back so many memories. Machine nes I learned the trade working on and rarely run into them anymore.

Thank you for doing a good job!. I have a 1997 5 ton trane. It's been flawless until this year. Started randomly tripping breakers. I called two different contractors out. Both spent 20 mins tops looking and told me the unit is old and the compressor has a intermittent short... I didn't buy that so I went investigating. Tested compressor windings following internet instructions, tested fine. The original compressor cap terminals looked nasty so I replaced it with a 5-2-1 hard start kit with the relay etc. Still randomly trip my inside breaker. Found my outside disconnect box had a loose connection behind the breaker and melted behind it, would get hot and trip the inside breaker. Replaced the outside panel for $18 bux and been running flawless ever since. What's bad is that even if I got a new unit it would of done the same thing. Intermittently tripping the breaker....then I would of really been mad!

Well done. Nice to see someone actually fix a unit.

Great Fix! Thanks for taking care of people and not being a sales tech. Keep it up brotha!

This is my favorite video of yours as it touches on so many aspects of HVAC and troubleshooting. The previous company that looked at this was not incorrect with their diagnosis. However it's refreshing to see a "fixer" doing a great job making that ancient unit work. No doubt a sales manager would be upset about your ability to get more use out of that system but that homeowner was certainly pleased. Great job! If we need to determine a good working definition for value, let it be from the perspective of the pleased homeowner. A similar situation happened to us an imagine my surprise when the tech did two unexpected things: He reversed the compressor leads for 1 sec to slam the compressor in the opposite direction and when that did not work he broke out the rubber mallet and went to work. So booster + creative temporary wiring and + attitude adjustment got it done. Go figure, it did unlock the compressor and gave us a few more months of cool. Of course we replaced it, but it was neat seeing those fix actions actually work. Counterintuitive but effective. Paying for the hourly rate prior to replacement is worth it in Florida heat.

You are a true hero to me! I absolutely LOVE these old units with the horizontal discharge fan, so glad that you took the time and were able to get it back up and running for her! I also recognized it as a Bard, we had a restaurant here in town with one. It was from 1980 and they finally had to replace it a couple years ago. It ran practically non stop in that place. The bottom of the unit was starting to rust out and somebody took some sheet metal and bent it up in there to get a few more years out of it. Bullet proof units for sure. I sure wish I had an old system that you could come service and save for me. They certainly will outlast the modern junk of today! Great vid man.

Good on you! I hope that someone takes care of my grandparents this way or when I get to that age, myself!

When testing a start capacitor with a resistor across the two terminals you have to cut the resistor to get an accurate reading. That may be why it was high.

When checking a start capacitor, you must cut the bleed resistor, can't be checked with bleed resistor, that why you got high capacitance, and can't have a rating higher then the cap is rated for. Otherwise great job in getting it running.

I replace run caps at about 10 years, it’s $15 to $25 cheap, it avoids rotor lock damage, and since 50% of failed a/c calls are for bad capacitors, it just smart. Keep in mind your tiny meter can measure microfarad readings but cannot detect high voltage leaks. Just replace the cap first and only if that is not enough, then add the boost cap. The biggest mistake is leaving the old crappy probably failing cap in and adding a hard start cap - which really just to counter the effects of a going bad run cap when they are tied together. No one can argue that a bad run cap causing rotor lock is good for the expensive equipment it’s actually protecting. It’s like car tires - you replace them well before they fail or go bald. It’s enhanced fail prevention service. Be a wise guy!

I do also take my time calls to make sure I troubleshoot diagnose probably and fix it properly to avoid call backs just the way I am and was thought to run calls. I've told this to companies that work for. And if they are not looking for someone like that lets not waste anybody's time.

Simple green diluted into a garden sprayer works well if you are going to follow up with a pressure washer. I try to avoid the foaming cleaners so the fins don’t get eaten up. Or I’ll use the Evap Powr-C cleaner and a pressure washer followup with good results.

What about voltage drop on start up? Didn’t see you verify that the voltage remained within 10% of the specified value, when the unit was drawing LRA. Also that original start cap seemed to have a low MFD rating for a start cap. Usually they are rated a lot higher. Good job

Here is a helpful tip clean all debris before working on the unit

One thing you definitely need is experience for sure. You have to be new at the game. Don’t use super heat on these old ones just have your high side inline temp 30 to 35 above outside temp and low side inline temp above freezing.

Can’t hurt the system and the system isn’t over charged that will also raise amps.

I meg a compressor sometimes. I usually only use a meg tool on generators if I feel the rotor or stator is shorted or grounded. This is a really old ac system. Yet most residential ac systems are split systems. With ductwork to distribute the air somewhat evenly through the house. Ductless unit’s are used when running ductwork is impossible or a room added on. If a compressor winding is grounded to earth the breaker or fuses will trip. Then it’s very easy to just check continuity of resistance from compressor terminals to the copper line-set since that is connected to ground.

@@thehvachacker If it's operating then I don't meg test. Maybe environmental conditions cause a lot more compressors here to short to earth, the windings still have enough coating to not show up with a Ohm test, but when power is on they short out. The laws here are a bit over board so almost everyone has a meg on them, every circuit is "supposed" to be tested with it. Also we operate with 230 or 400 Volts so that might make difference in what fails more often.

And we get a lot of breaker trips here from many things, it is a good sign of compressor fail as you said, but 50/50 here from gecko's and rodents, and PC boards in single phase units that run a 3 phase compressor (the PC board takes our 230Vac, rectifies it to about 250DC, then square wave 400Vac with low amps). It's expensive to get 3 phase here, 2 phase is basically non existent, so manufactures cheat a bit and try all sorts of fancy tricks. I've done about 4 package units in my life, they are my favourite but unknown and expensive here, Split ducted is the "upper crust" solution, but mostly single split systems or multi split systems (one indoor head with no duct) or VRF and VRV (multiple indoor heads and one huge outdoor unit, shared pipe work). It's mostly a retrofit game here, 5 single splits per house or 20 per office is fairly common.

If the run cap is good it will limit the rates of voltage rise (or spikes). If the run cap went open circuit then the insulation is at greater risk. Many technicians will replace a weak 370 volt cap with a 440 volt cap to negate future failure. Many Inverter supplies lack filter caps and plow nasty voltage spikes into the compressor and that can damage the insulation. It's a combination of voltage and frequency(rates of rise) that initiates arcing and breakdown of insulation.

That coil was very stopped up, very neglected. I have to clean my outside unit every month because of all the cottonwood seeds floating around in the spring and early summer.

Looks like a Lennox HS6-411, Late 1960's, maybe early 1970. R-22 much better at dehumidifying than 410-a. Lower evaporator temperatures, more condensation. Older units had thicker copper coils, fewer refrigerant leaks. May save energy with newer units, but will spend more on maintenance, especially if going to the new ECM's. DOE is clueless on mandating energy savings. Lennox came out with condensing furnaces, Pulse, long before DOE mandates.

I have a cuestión...why do you use only fieldpiece but not testo

@thehvachacker

4 жыл бұрын

Fieldpiece made a superior product at the time. I was a testo fan if you watch my older videos. My 550 lasted 7 or 8 years before going down. A few of my coworkers had the testo probes yet barely used them. No range and constant dropping connection. It’s why I chose to invest into fieldpiece probes and haven’t considered anything else. Tools are an investment. Do you have the testo probes? Most techs at my shop use the testo gauges since management orders and allows payments. Many of my subscribers talked up the fieldpiece probes. I’m sure the newer gen of testo probes have been built better than the last generation. I use the same tools all the time until they break

I’ve got a similar issue except my compressor runs for 15-30 seconds with the hard start kit and then shuts off. Current Ac guys states the compressor is no good. Do I need a second opinion?

@coldkill47

A second opinion when changing a major component or even the entire system is always a good idea. Like a second opiniom from a doctor or a car mechanic. But from my experience compressors with a hard start kit are usually on their last leg. But there are a couple things that could cause your system to short cycle. Call a small company, not a big name that markets a lot.

@throttlebottle5906

just make sure they tested or replaced the run capacitor, it's probably dual section, one side for compressor and other for fan... adding a hard start kit when the run cap is bad can cause that, but many other things can also, bad run winding, low charge/no oil damaged compressor, bad thermal overload inside.. wise to always have a few people check the units and get a few bids

You need to find one good HVAC tech that you can trust and use him or her only. Asking if you may need a 2nd opinion tells me you haven't found him or her yet. Yes, i know a female tech that is really good and easy on the eyes too which is a bonus. She doesn't like it when i say that but she knows men are men and we can't help it... It's all about relationships in the service world especially in the HVAC field. Good Luck.

coldkill47 older systems usually came with hard start cap because stuff was made better 40 years ago. Now the manufacturers are so cheap they would rather sell you a unit without one so it dies right outside of warranty and they are cheaper to manufacture. All units should have them, especially if they are fitted with a txv. I agree tho that a hard start isn’t usually put on nowadays unless there is a problem, so if you see one you can probably assume the compressor isn’t to healthy.

I bet if you did the old school target superheat formula. Wet bulb x3-80-ambient temp outdoors,divided by 2 You'd get that (sh) calculation very close to yours. Seemed like in your video you may have been having a little trouble, getting it off your probe. I love that formula, been stuck in this old head seems forever..

Charging to feel of the suction was what a tech showed me about 20 years ago. Yet with ac systems pistons was always charged to superheat and TXV get charged to subcooling. Problem with trying to charge a piston to subcooling is the subcooling is always really high.
