I found this out after awhile . I could not figure out how my house was still tough to cool down at night after it reached 95f that day . Explained to me the house collects a lot of heat in the house itself such as in the walls . I also learned it is a terrible idea to turn off the ac when out to work as it was impossible with my central air to recover for such high heat .

Was taught in school that you save 1% on your energy bill for every degree you set your tstat back up to 5 degrees. After 5 degrees, you start going backwards on savings. When most people hear that they only save 1% they leave it set to 1 temp.

[@bstevens9831]

Maybe a programmable thermostat would help. She can match the programs to her work schedule and allow it to run at a *slightly* higher temperature ( like 78º ) when not home. As you said to her, there is no way that unit is going to cool down to 72 at mid-day ( max heat ) when the inside ambient is 80º +. She's lucky you've kept that old Rheem running for her. Keep up the good work.

[@Garth2011]

One thing I noticed Curtis was the condenser fan motor did not "coast" when you spun it by hand. It came to a stop rather quickly vs. spin a couple of times before coming to a stop. Would a new problem free motor slow down that quickly, I'm guessing to be a no. I have noticed USMotors has the "Mojave" model and they are rated for higher outside temps and additionally they use "ball bearings" vs. the "self aligning" sleeve bearings. I'm just guessing those are more robust and for less than $10 more, a better bearing for the long run. I know, some HVAC folks might disagree about bearing types but its been my experience the most common reason motors need replaced is because the bearings fail and lock up the shaft. Could be that motor is going to be defective soon.

[@brianb8011]

I thought I was the only one who noticed that. You would think for a brand new motor that thing would have more spin or spin freely a little better.

You're correct, always select ball bearing motor replacements!

Sounds like she first said she turns it completely off then suddenly changed her mind saying someone stays there and that she does not turn it off . Odd . My first thought when he pulled up to the outside unit was it has to go . What a noise sore to the neighbors . But many cannot just up and replace there central air units . All in all central air is terrible for anything 90f and above . In this case , even if she keeps the unit on it will still have a tough time to keep up . Age is part of it in her case but even new (builder grade) units struggle at 90f and above . I hear it all the time in Florida where i live . That’s central air for you . Yes i got rid of my central air . Unless they have been improved over the past 10 years i will for now on avoid them .

[@jimjr9143]

Not just that . In many cases if not most , people really do not know technical details on how ducted central air works

[@MariosACandRefrigeration]

You need 18 to 20 deg delta on a unit that old,they had bigger compressors,you need to check return plenum for leaks,and to see if the house is negative ,if it is you have a supply duct leak .the suction pressure is high for a 74 deg return..2 cents.

[@jthonn]

That would do it, but I doubt that's the case.

[@sentryfe74]

Could blower fan speed be too high?

[@topher8634]

Overfeeding expansion valve will cause high suction too. But I'd be willing to bet there are leaks in the duct work. It's a single return system with the mechanical closet open to the attic. My experience with that setup is there are significant leaks especially if there has been a replacement system installed. It is difficult to seal around the coil and supply plenum when the space is just big enough for the equipment.

[@jthonn]

@@topher8634 True, if it is open to the attic it will never be right.

[@MrRupus2020]

My parents had the same setup with uninsulated ductwork. Old single pane windows and very little insulation on a conventional foundation. 77 is about as low as youd see on a hot Mississippi Summer

[@BlenderRookie]

Some people are convinced that turning their AC off while at work will be cheaper than leaving it on. It's way better to pick a reasonable temp like 75 or 76 and leave it there. It takes way more power to get rid of a lot of heat to cool it off vs getting rid of a little heat to maintain temp. I have tested it and typically in my case it will take 15-20% less power over a week to maintain temp than it does to bring the temp down just to let it go back up day after day. In this case the unit seems underpowered.

[@JJ-Toreddie]

Correct. Also, residential units tend to be undersized

[@eaglebill3738]

Thanks for another great video Curtis. Definitely an issue of on-off operation. I'm retired from school district HVAC operations and the first thing learned with AC is the air has to dry before it can cool. She indicated that it's operating continuously but it feels stuffy {6:44). That's because it hasn't had time to dry out the building and all the stuff in it. I believe your geographic zone can run dew points in the 60's? If so, running on-off won't work at all. Let alone factors of poorly sealed single pane windows and opening and closing doors or leaving them open etc. Especially every day, it will never have the capability of drying out the house. Basically as soon as it begins to get to the drying process, she turns it off and the system has to begin all over again the next day. This is most likely costing more than if she left it run all the time. Not your fault at all Curtis, Landlord shouldn't be upset with you. You certainly did your due diligence in making sure the system is performing. This is a great video to learn from.

[@stevehullings704]

New motor doesn't seem to spin freely, that didn't alarm you, brand new don't mean jack anymore, I guess we'll see . Of course customer thinks ac will instantly cool house down in minutes. That unit needs a cinder block on top to keep it from making rattling noise.

[@bobboscarato1313]

It sounds like grossly overcharged unit; I'm surprised compressor didn't burst!

[@Chris-ec9lc]

should the fan blades be so close to the motor? Maybe a lower profile motor is what should be in there too. And it spun like crap

[@topher8634]

Amp draw was below FLA. If it were dragging, I'd expect it to be over it. suction press was elevated but he said it was 80 inside and the system has been off, so it was a high heat load. Subcooling was a bit high, I don't know what the design subcooling temp is for that system, but I would not expect it to be over 15. High side pressure was 260-what you'd expect on a 90 degree day with an old 30 degree split condenser

[@hvacshinobi8047]

Duct leakage and maybe Retrofit cocktail, refrigerant mix topper, possible issues

[@andreeriner811]

No wasn’t your fault. 15 16 degrees is not fantastic, but as you said on a unit that old that’s no surprise at all. I had a heat pump that wasn’t keeping up not long ago. I think what I found out on that one the reversing valve was stuck partially. Wouldn’t go into heat at all. Wasn’t shifted all the way in cooling either.

With an older air conditioner it will have to work extremely harder to cool the house down. Like you said in the video don’t turn your air conditioner off before you leave because you’re going to have a very hard time getting the air conditioner to cool the house down.” I, agree with you!! Don’t turn the air conditioner off you should raise the temperature a few degrees. I hope the tenant learned her lesson! Do not turn the air conditioner off before she leaves the house. She needs to raise the temperature!!

[@darrolreeder235]

Judging by your air temp at the vent (I believe it was 100 degrees until you turned the condenser back on), you may very well have a heat strip that is energized if that system has electric heat. (sequencer stuck) Other than that, your advice to her about turning the system up or off during the day only allow everything in the house to go up in temp (that includes furniture) and all of that heat must be removed before system will start cycling.

[@raykrv6a]

Thank god I live in Minnesota. It may get up into the 90's, but it cools down at night. My house is 72 during the day and 66 at night when I crank the AC down. Just got my April Xcel Energy statement and I only used 432 kwh and that's less then half what other nearby home use.

[@JHACbiz]

Have to agree that motor didn't look like it was spinning very freely but we'll see. The biggest issue is clearly that she's turning it off. I always give people the analogy of the home is like a battery taking charge all day long. Every bit of material in that home is getting warmed up and more and more humidity because of the air is not being conditioned so when you get home turning that air on it's got to cool all that material down expending all that energy over and over and over again. Much better to maintain a set-point plan.

[@melvinwillingham233]

Residential structures are only designed to maintain 78 degrees inside when its 92 outdoors here in north Georgia. Most systems have a little bit more capacity and on a 95 degree day you might be able to get the inside down to 75 degrees.

[@Deploracle]

There is more than just heat in the air to remove but heat contained in all the furniture, the walls, appliances, carpets. That is why it is usually most efficient to leave the thermostat at one temperature. If all that stuff in the room is allowed to get hot again, it will take that much more time, and that much more money, to cool the room again when you get home. Once all the aforementioned items in the room arrive at your set temperature, they act as buffers to help keep the rest of your living space at a constant temperature.

[@shermanmaddoxrcpc774]

We use a setback thermostat on our old system in summer we’d set it to cool around 3 hrs before we got home. It was tolerable. On 100 degree days had to use ceiling fans

[@theshaddowaust]

Sorry a bit long winded but. :) When I was in the trade FT, I had one place that had a Daikin ducked system with a huge 3 phase out door (8' High 4' wide) (YES LARGE HOUSE too), they was complaining the unit would keep going all night and not cool the place down + huge power usage because of it. We had visited the place many times and then the head of Daikin rep's came up and we headed to the place to find no problems with the unit,(Every visit they had someone home and so the unit was on the hole time and working link it should) It then was coming to a point the owner kept complaining so one day we headed there without telling the owner (100o Day) and found the unit was not running outside, called the owner and he turned up 30 min later. The first thing we found was the thermostat was off to find out they was doing the same as this video (turning it off when they head out the door). Tho we had asked and asked if they turned it off when they leave and it was always a "NO" even when the rep was here. They didn't like the bill we had to send, for the wasted time visited and even the rep did too They still expect it to get to temp within 10 min of turning it on. It came to a point that they asked another place to look at the Air Con and when they saw the installers name called us (Good Friends) and we told them the same thing (Billed for that visit too). Surprising part: We did get an apology 3 months later when he decided to read all the paperwork and followed it and so found out we was telling him the right way to run it, and so the power bill went down and the house kept to temp.

[@brettbussell1077]

Curtis, I've been an HVAC tech for forty years. I notice that on r22 systems you always overcharge them. The industry standard has always been 63-70 psi on the suction and 30 degrees delta T on the air temp in and out of the condenser with pressures from 200-280psi depending on OAT. this unit was a bit overcharged. At 80 psi the saturation temp is 48 degrees and at 67 psi its 39 degrees, still well above freezing and a better delta t across the coil. I hope this helps as I am usually impressed with your skills.

[@OGHVAC]

Agreed. 45 years as a technician and retired now but that little system looked over charged for R22 to me as well.

[@chrisspanyer1525]

I noticed the super heat was only 10 degrees. I’m assuming it was at least 80-90 degrees outside as she said it never gets below 79 inside. Also the wet bulb was 74.6 (I think hard to tell bad image quality )degrees so should have had super heat of about 30 degrees. Assuming no other problems with airflow. Seams over charged.

[@mortimergladbreath]

Not just the air in the house but all the mass of walls, furniture, everything is heated up and has to be cooled down as well. Nice lady, but sometimes people just don't get it.

[@Garth2011]

Even though the "utilities" say to alter the temps when you sleep or leave the house, I have to agree, set it where you want it and leave it. Remember, power companies sell electricity and when your A/C runs more, they make more money. I recall years back some news journalist was interviewing a Walmart V.P. about their operational costs and the man had said they did several recommended methods for controlling temperatures inside their huge stores and they finally discovered that setting the thermostat's at the number they chose 24x7x365 used less electricity for them and maintained inside temps best and their observation was keeping all of the mass inside the stores at a controlled temperature was cheaper than allowing temps to rise then try to recover them again the following day. We do the same at home...we're home most of the time or at least someone is at the house most of the time so we set the temps and leave it there all summer, day and night.

To be fair to the tenant, the HVAC industry has stuck with single speed systems for too long. If you had more multiple speed systems, then you could have more capacity for peak cooling while still allowing things to be comfortable during normal operation. I live in upstate New York where days vary more often between warm and hot. Heaven forbid you get too busy and miss the weather forecast and leave for work without turning on the AC on an unexpectedly hot day. Or you have relatives come over during the day and change the thermostat setting. Or the power goes out for several hours after a storm. Or you go away for a few days - like leaving on a day when the high is 70 and getting back on a day when the high is 88. There is no way I'd stick with a single speed system the next time mine gets replaced.

[@rbking9296]

I have been binge watching your videos they are very interesting been having problems with my AC unit got to have a new evaporator coil installed tomorrow but what I have noticed watching all of these videos of yours is it seems like 99% of the repairs you are doing are all on Rheem units are they really that bad….. enjoy your channel you seem like and honest and very professional HVAC

[@NEW_INSITE]

I did apartment maintenance and also the heat and air on all the units, I was certified in heating and air in case anybody asks, And I had to explain to tenants many times not to turn the unit off but to just turn it down if they were out of the apartment. I had to explain to them that not only does the air in their apartment get hot, but also all the sheet rock in the whole apartment, which is a 1/2 inch thick or more, is basically a rock which absorbs the heat all day long and it takes a long time to cool off a heated rock that's been sitting in the sun all day.

[@TomLawson05]

Great call Curtis callback not your fault at all thanks for the video

[@CA-lk6fd]

I don’t think that’s your fault. You told her right, she’s trying to recover around 10 degrees plus the humidity, not gonna happen even in a brand new home with a brand new unit. We only drop ours back 4 degrees during the day, I wouldn’t go anymore than that on ours because it would be the same thing hers is doing. Honestly she’ll probably save money doing it the way you told her verses what she’s been doing. We have a 14 year old 3 ton Rheem split unit HP cooling 1900’ in Kentucky. It does really well at 72 setpoint even in 100 degree weather.

[@rickhendrickson3530]

Definitely bill for it

[@rolytech212]

You also have to see how well insulated the attic is. Rentals don’t have attics well insulated and with these temperatures in the summer it may be a problem

[@HVACGUY]

I tried. Access was likely in the other apartment. No access while I was there.

[@rickknosky6547]

17 degrees sub cooling? Seems like it may be a little over charged.

[@daultonbowers6897]

I was thinking either a little over charged or heat strips running, seen it a few times on those old ruud/rheems with sequencers

[@vincentgelles3805]

I had one of my Fieldpiece probes do what yours was doing there. I use Measure Quick because I’m not a huge fan of the Fieldpiece app, and I have a psychrometer for outdoor air. I noticed my head pressure target was bouncing all over the place so I checked the outdoor temperature and it was jumping from 85 degrees to like 55 degrees all the way down to 28 degrees then back up to 85. I put new batteries in it but it didn’t fix the problem so I bought a new one. If you had a psychrometer doing what mine was it would affect your Delta T like what was happening in the video.

[@navycorpsmanveteran61]

Had to turn the volume down. That unit was loud.

[@ALWATTS83]

If she concerned with the light bill. Sell her a 20 seer Bosch. Pretty sure as old as that unit is it’s not running at peak capacity. Nevertheless you’re correct can’t shut it off then expect it to cool it’ll never catch up

[@williamserver4332]

Thanks for the videos. Very informative

[@Sctronic209]

In your area I notice big time lacking insulation in the attic’s. That makes a huge difference on heating and cooling.

[@bladimirbetancur327]

I think the issue with the 20 plus years unit is the CFM(cubits feet per minute), condenser air flow ratio or inside unit blower fan air flow ratio. The numbers may look good on the charts delta t or thermostats for saturation, superheat or subcooling .also there may be a restriction in the air flow in the condenser coils, people cut grass there every once a while the grass looks pretty trimmed and mowed ,you should check the all those things to rule out any inconsistency . When I say cut grass meaning debris flies and get sucked in the condenser coils creating air flow restriction to efficiently cool off the hot refrigerant ,or maybe the brand new motor is just not match for the age old unit too fast or too slow CFM .MAYBE when you put the amperage check it showed up 1.00 amps and the motor says 1.5 amps running amps . In this case ,keep in mind every year there are improvements in motor technologies, perhaps is of higher efficiency and less resistance the reason it requires less amps to run. Better copper windings design or better build. Maybe is too fast and air is not dragging slow enough to cool in the evaporator. I would check with the manufacturer of the unit and look up recommended speed of condenser fan.

[@DennisDuffy-n8g]

[@stardust-rv7mr]

maybe adding a window unit in the hottest part of the house would also help! brick houses, once they heat up they are very hard to cool down!

[@robertoja2091]

Your patience is key, but I gotta be honest. This is why I don’t miss resi

[@billj4859]

In my opinion. If you hook up a gauge to a system connect a thermometer or your pressures can be useless. The fieldpiece app will tell you what range your outlet air should be. There's a ton of information there you don't seem to be using. I understand if it's not on camera but seems to be information left out of the job notes. I work on a lot of old garbage and the more info you document the more it covers you.

[@dh5594]

The condenser fan sure seemed tight when you spun it and had alot of play in the shaft and you said it was extremely hot too. I bet if you changed it it would pull the heat out better

[@chrisnapier5626]

Great job,Curtis!

[@jthonn]

Not your fault. Rule of thumb you can only pull down 20 degrees. That old unit is kicking booty. My only suggestion would be to put a window unit in the living area to give it a hand, if she wants it real cold. Also don't block the intake with clothes hampers or anything.

@@markchapman4197 Looking back I see you are 100% correct. My bad.

[@krishuntzeroable]

Do you keep logs of pressures from previous visits? Reference them, tell them they need to upgrade. I mean just look at that Ruud system. That would be a no go in Louisiana. Convince them to upgrade so they can stop blaming everyone else. What you said to the customer was 100%. When I’m gone I keep my place at around 76, around 8-9pm it keeps it maintained at 74. It’s comfortable enough for my roommates not to bitch. But it’s also 100 degrees most days. You can never expect a system to kick your house down lower than 70 unless you’ve got a newer house with double panned windows and lots of insulation. No cool air loss within the building and I always suggest attic tents if their thermostat is above the attic access.

I’ve had to put in larger top cabinet screws in those old Ruuds to stop fan vibration noise since the old holes strip out… Just don’t do that at the bottom since there is minimal clearance to the coil.

[@polishsharpshooter2876]

I would have washed that coil and used a 1075 rpm motor and a new blade. I also suspect an overcharge or a hunting txv causing that horrible delta t

[@kevinwalker4623]

He said coils were cleaned the first visit two months ago. Can you just arbitrarily change fan speeds or go with what the oem specifies? How would a new blade help on a twenty year old system that apparently worked fine until this tenant. I don't know, I'm not an a/c guy that is why I'm asking these questions. Had a guy tell me in my truck when its hot, put the a/c fan on low and crack the windows and the truck cools faster. It seems to work. He claimed it gave the gas more time to absorb the heat.

[@polishsharpshooter2876]

@@kevinwalker4623 the old blade is likely off balance causing the horrible vibration. The increase from 825 rpm to 1075 rpm will move more air helping the unit cool down the condenser better. Its not more efficient on electricity cost but more efficient on how much cooling you can get out of unit. Kind of like spraying water on the condenser in hot weather. You get more capacity. But that delta t was horrible. I still suspect overcharged or hunting txv. The unit is not doing all it could do

[@wiedapp]

That yard helicopter itself would even be a violation of code for excessive noise, as in living zones only 35dB are allowed at night and 45dB during the day at the nearest window of a neighbor. That thing is way beyond that. With a noisy outdoor unit like that you won't have many friends around here. Here some people only need to see an outdoor unit and complain about the noise - even though it's not connected to power or anything. Just. Standing. There.

[@aubrey5939]

Also there also seems to be a latency issue with Android phones compared to iPhones.

[@Leroy63]

A perfect similarity to the propaganda of programmable thermostats and setback temps. Not many people think of the thermal mass of literally tons of furniture, drywall, and other stuff that also gets to that 85 degrees that the system also has to cool back down. Thermostats are like the Ronco rotisserie tag line set it and forget it.
