I love the way people install these systems and seem to be thoroughly convinced that they will never need to be serviced.

@michaelleeper3649 Год назад

I am amazed at how complicated these systems can be. The closest that I came to your line of work was changing filters and belts in the roof mounted units on factories, restaurants and stores. I almost lost my arm in one while replacing the belt. I moved to grab a tool and just as my arm was clear the unit kicked on. It turned out that someone bypassed all the shut offs that were located next to the units. Every single unit was tampered with. I notified the fire dept anonymously (they did the safety inspections). I didn't want someone else servicing them getting hurt or worse. I knew that telling the property manager would be pointless as it was their people that did the bypassing. City inspector and Fire Chief were involved. That place was a fire and death trap and the fines were in the thousands.

We work on a ton of those old Rheem/Ruud coffin style systems, mostly because my company installed them many years ago, and I love them. The condensers especially are super service friendly. And we still install Rheem equipment, and it has proven to be really good stuff. Very rarely factory defects, shipping issues, or warranty repairs.

@Kangenpower7 Год назад

I just installed a 18,000 Btu heat pump for my neighbor, the ductless unit is not the correct size for their home, but it is what they can afford. They bought the unit at Amazon for $899 including the tubing kit that is 15' long. I installed it in their living room, and told them they would still need to run their electric furnace with a 10 KW electric heater on the very cold days, but at least they can avoid running the electric heat most days. They are VERY happy with the nearly silent system. It is R-410, 17 SEER, and 9.0 HPSF. IT is all they could afford. I know the 21 SEER 10 HPSF model will save them money in the long run, but the $1,200 cost was not in their budget this year, so they went for what they can afford. I think the ducted unit was probably about 24,000 Btu R-22 heat pump that died about 15 years ago, before they moved in. They have been running the electric heat all these years, and I did not know about it. They could spend $200 - $400 a month in Portland Oregon, where 32F is a rare event most winter nights. I was 23F for 4 days recently, and they reported no problems! My heat pump had so much ice on the top of it, that the ice fell into the fan and prevented it from turning, and I discovered this the first 34F day we had, used my garden hose to thaw it out and run the fan without the compressor wire connected to thaw any more ice on the coil. IT has been in the upper 40's now, so everything is back to normal. I have a 2014 Goodman 14 SEER R-410 4 ton system with 1,800 square feet and I never connected the back up heater. Yes I get cold air during defrost, but I am OK with that. I sized my system not for the cooling load (like many do) but for the heating load at 23F. So it is rated at 25,000 Btu's at 23F - the lowest outside air temperature that I will normally have to deal with in Portland. I only have below 32F for about 30 days in 4 years. (some years never go below 30, this year we had 4 days so far). I have a feeling that the modern heat pump will save them about $100 per month for November to March. So payback will be in about 2-3 years. Also the air conditioner will be Silent! So no more buying window shakers! And this unit should use about 2/3 of the power of those window shaker units. I have a feeling that if the customer installed a R-410 system, with lower refrigerant costs, and higher efficiency, they could have saved the cost of the new system in a few years.

@jthonn Год назад

@@Kangenpower7 I agree with you totally. My system is a 4 ton Goodman, not a heat pump, but a split system and it is only 12 seer. It was a good one, never touched it for 13 years. The dang evaporator started leaking slow and I've been limping along for 4 years now. I know when it needs a charge because the efficiency goes in the dumper. I am going with all new and I am leaning towards the Rheem. I will post what I get when it is time. Not sure yet if I am going to change the whole air handler and furnace or just the evaporator, on the fence right now.

@adamrspears1981 Год назад

There are 2 ways an AC system comes out of a house: When the homeowner wants it to. Or when the system wants to. I'm am big fan of letting the homeowner decide when it comes out. Because if you leave it up to the system to decide, the system typically fails for its last time on the hottest days of the year. There are advantages to being able to offer homeowners financing. Where I live, a new AC split system costs at least $14,000. That's about as much as a lower priced new car costs. & I see a lot of people who live pay check to pay check, driving new vehicles. So they way I see it, is if they need a new AC system that costs 14 grand.....they'll come up with the money, or get financed through their bank if th installer can't finance them. Believing that people can't afford a new system, is not an excuse to convince them into putting a large amount of money into a major sealed system repair, if the system is out of warranty. This is why we owe it to our customers to give them both repair estimates AND replacement estimates. & then let them decide which they would like to do. & if they want to put over $1000 into a dinosaur system that already lost a significant amount of its efficiency due to excessive age.....then that's on them if they end up regretting it. But a company that has not presented them with all their options on that initial call....has done a dis-service to that customer, & SHOULD take full responsibility if the only option they offered back-fires on their customer. Its all about honesty & equipping your customer with everything they need to make the choice that they feel is best for them.....regardless of what the price tags are, on those choices.

The coils are the same for the most part. You can set it up with the expansion valve, expansion tube, TXV or what have you for the freon you use. Curtis used the mo99, so you can use that in a r22 system without changing anything.

@FatManDoubleZero Год назад

In Texas where I live, most contractors would price a coil replacement at $1,800-$2,200.00; basically forcing the owner to REPLACE the entire air-handler. I can see you are trying to help someone who needs cooling but has limited funds. Hope the customer gets a few more years service life out of his equipment, thanks to you Curtis. Kudos.

@Kangenpower7 Год назад

The last time I bought some R-22 it was $800 or $850 for a 30 pound container back in 2018. I think it has gone way up since then. I would never recommend a customer stay with a 10 SEER R-22 unit, just because of energy costs! It is sort of like rebuilding the engine on a 1975 car that gets 9 MPG. I would be selling them a modern heat pump with R-410 and much higher ability to collect heat when it is 5F outside! Back in the early 80's R-22 and R-12 both cost about $45 for a 30 pound container. Then the R-12 tax started to make them cost well over $125. In 1993, I got certified to use a refrigerant recovery machine. When I went to school in 1983, they did not have a recovery machine, I think it was about 1987 before I heard of them.

I like how you shimmied the valve core out while removing it under pressure. I’ve had problems with the schrader valves getting stuck and having to push the end back in multiple times thinking it grabbed ahold.

@jrtakesthesky27 Год назад

It's from over tightening the tool on the flare of the king valve. It will squish the large o-ring the tool has and obstruct the path for the core to be removed. If you have trouble getting the correct torque, just loosen the core then very slowly and carefully loosen the tool till you get a faint hiss as if you are purging, trying not to lose any refrigerant. You now know where you can have the least torque leaving the o-ring not deforming.

@jthonn Год назад

Nothing wrong with a little pinch in a pinch. You did a great job on that old system. That evaporator looked crooked, but may not have been helped. Personally, I would have tried to sell them a new system, maybe you did and it was unaffordable for them or one of those home insurance jobs. Well we will see what the future holds. I am sort of in the same boat. My unit is an old r22, but I am afraid if I just do the evaporator, how long before the compressor or condenser coil goes? I am going to bite the bullet I think, not sure if I can limp along another season. At least I have gas and it is not a shmeat pump.

Curtis, what would be your first guess/diagnosis on a blower motor that runs normally sometimes, but then takes longer then usual to come on during heating cycles? I seem to have that problem. It is not making any unusual noises such as grinding/squealing to signal a bearing is going out. I have a gas furnace, and everything else cycles on as it should.

@johncspine2787 Год назад

How long is longer? Longer than cooling? Furnaces (at least the gas ones I know) have a way to sense the temperature and then kick on the fan..but there’s usually a small delay, you hear it click, then the draft motor and ignition, then the fan sometime after that..if it’s really long then could be a sequencer isn’t working right, or a flame sensor is taking a while or is slightly out of position, or a control board is sending wrong information or..I’m guessing, hvac isn’t my thing..but I have learned quite a lot from his videos, lol..

@jamesboyd6174 Год назад

How did you get ahold of a r22 coil?

@HVACGUY Год назад

It’s still available

@Kangenpower7 Год назад

They sell the R-410 coil that is rated at about 550 PSI, and will also work with R-22 when you use a R-22 expansion valve. The R-22 normally does not go over about 350 PSI, and normally has a high pressure cut out at about 400 PSI, while R-410 cut out is much higher pressure. So the R-410 rated coils should last longer leak free than a R-22 coil that has a lower "Maximum service pressure" rating. That said, many installers will say (and salesman) that the R-22 coil is not available to get you to buy a new R-410 system. My thought is to offer the customer a choice and say "This repair comes with no compressor warranty, and the energy cost will be so much per 100,000 Btu's of heating and so many KW per 100,000 Btu's of cooling capacity." And the modern high efficiency R-410 unit will cost this much to get 100,000 Btu's of heat and 100,000 Btu's of cooling. This is normally about 20% less electricity than the older system like the 10 SEER units installed in the year 2000 by a tract home installer. (Who knows it might be a 8 SEER, I installed a couple of those back in the early 90's). 14 SEER will typically use 40% less power than a 10 SEER system. This is why many times they need to install a smaller circuit breaker to protect the newer high efficiency units. When I replaced my 1972 18,000 Btu unit (amp probe says it draws 18 amps of power) with a 24,000 Btu 12 SEER unit in 2000, I replaced the 40 amp circuit breaker with a 20 amp circuit breaker. My new home, I have a 48,000 Btu 14 SEER heat pump and 30 amp fuses, they never tripped in 8 years! It uses so much less power than the older units did. And in a heat pump, the higher suction pressure generates a lot more heat in the winter, making heat pumps run much better than this 22 year old system.

@throttlebottle5906 Год назад

most all R-410a coils will work fine with R-22, as long as you install a correctly sized piston or TXV. they're often listed and rated for it, and give the proper piston/txv, which you need to order separate or have on hand.

Can you mix mo99 with 22?

@Kangenpower7 Год назад

The idea is that you "Should" not mix MO99 and any other refrigerant. This is because when you recover MO99, it goes into a MO99 recovery tank, and not a mixed refrigerant tank. The mixed refrigerant tanks are much more expensive to send to a recovery place. There are other reasons to not mix them, also chemical reactions between the two fluids, and different pressures and so on.

@jcbecker2800 Год назад

@jthonn Год назад

I agree, but maybe there was a reason.

@Kangenpower7 Год назад

I agree, but this neighborhood probably does not have many Land Rovers in it. I like to tell the customer that the older R-22 systems do not collect as much heat in the winter as the modern R-410 systems, and that a 10 SEER system will use about 10 KW of electricity to heat or cool 100,000 Btu's while a 14 SEER system will only use about 7 KW. So a huge savings over the long run. And the new equipment will usually come with a 10 year compressor warranty. However if investing $1,000 in a repair means they can keep buying food for the kids and investing $4,000 is not a option, you have to do what you can afford. So saving $0.40 per hour and only running the system about 1,000 hours per year, it would take a really long time to pay back the higher installation costs. Yet it might help if there is rebates for installing higher efficiency heat pumps in your area. A $200 per ton of capacity rebate could save about $400 - $600 on a system this size, and by saving $400 a year in electricity, and not needing to do the $1000 repair, the savings for a new $4,000 system is starting to look better.
