How SEER2 Broke The HVAC Industry! SEER2 Explained

[@paulmarc-aurele5508]

I retired from the HVAC industry 5 years ago and think higher efficiency is good to a point. More importantly is keeping ductwork out of attics and building houses better. A house that by design that requires 50% less cooling is better than a cooling system that has expensive motors and controls to gain a little efficiency. On one of my last repairs I remember an ECM blower motor that cost 750 to replace. It never saved the difference in electricity as it failed in 8 years.

[@CD-vb9fi]

Yep, we design everything like trash these days. everything. Cars, houses, computers, and parts for them.... garbage all the way, unless you find rare quality, because the industry likes "recycling" and I don't mean that in the "beneficial" sense. It's not the duct work must be kept out of the attic, its that if the duct work is in the attic, it needs to be conditioned as well. If not... then you are totally right it should be kept out of the attic. The other problem with repairs is the "limitation" with self repair. Things are built to intentionally limit repair by owner. Parts are always changing shape, size, and mounting in slight ways all the time. Mfg's keep stock exclusive to themselves and the "authorize repair" dealers as much as they can. Nothing but corruption and trash... every industry, no question, no doubt.

[@rb8049]

There is no reason an ECM motor should cost this much. The components are cheap. They are just jacking customers because they can.

[@GilmerJohn]

@@rb8049 --- In the fullness of time they may become cheaper as the electronics driven motors can "simulate"" a motor of it's HP and speed on down. The switch between a two speed to a variable speed might just be a jumper change.

[@xeridea]

@@CD-vb9fi I never understood why houses were designed to have the HVAC in the attic. Surely surrounding the unit and all the duct work in a sauna can't be good for efficiency.

[@robertsmith2956]

It is bad because nothing happens in a vacuum. Just look at commifornia, they forced everyone into efficient and electric cars, now they are punishing them for not buying enough gasoline. The power company will NOT take a hit, how will they bribe the officials. You will pay just as much if not more for using a more efficient AC.

[@johnhaller5851]

Even before SEER 2, my dealer had to remove the fence to get a 3 ton Carrier Infinity system into the side yard. That is not a small unit. But, it probably meet SEER 2 minimums before it was required.

[@JosephWett-vw7zp]

It was also bean counters. I’ve installed tons of Carrier units (pun intended ). Some outdoor units were huge because it was cheaper to have a single row coil and larger cabinet instead of a two row coil and a stronger fan to pull the air thru it.

So, to summarize. SEER2 was a good change because it more realistically depicts how a system is actually used ( .5 static is still low for most actual installs in the US) thus giving consumers a better idea of how the equipment will actually perform. OEMs have been optimizing for the old unrealistic test and even though they knew the change was coming put off redesign and building the new units until the last minute. This caused some logistical difficulties.

[@sand0can1]

Are you telling me that the installer after installing the system measures if it will pass SEER2? Of course not! What is the complaint about? The condenser size is not an issue the handler is only an issue if you didn’t first measure the homeowner dimensions and got a bigger unit even though there are smaller units.

[@Beastphilosophy]

"Some logistical difficulties" is a bit of an understatement given that no one appears to be able to source an efficient RTU within 20 weeks right now. That said it was a long overdue change given that most people have a filter attached to their HVAC system and at least some ductwork. I can count on one hand the number of houses where I measured less than .5 tesp.

Everyone said that these changed made AC more expensive, but where is the evidence of that? The cost of living and the demand for higher salaries by workers, higher cost of health care, insurance, and energy, the supply chain, cost of materials, and shipping have far more to do with pricing than the change from SEER to SEER2. The engineering and design changes to get to SEER2 probably had a minimal impact on the price of the equipment.

[@shenmisheshou7002]

@@ch3vy327 I it is labeled as SEER 14 because that is a more accurate description. SEER used to be tested with .1 w.g. static pressure (essentially no supply or return duct, so no pressure losses). Seer 2 uses .5 w.g. to better reflect the real world static pressure. A 14 SEER system from 5 years ago would really be lower if measured by today's standards. so the equipment is not really the same. My 4 ton 16.5 seer 2 stage has noticeably larger coils both at the condenser and the evaporator than the 3.5 ton it replaced, but 80% of the time, it is only running at 75% (3 ton). While it is not hugely less expensive to run than the old 15 SEER 1 system, it did not cost that much more than a new 3.5 ton would have cost. Payback is only 8 years, and the unit will probably last about 12 to 15 years. Now that being said, the cost step between single stage and 2 stange is pretty small, but the cost jump to a full inverter system is very high and seems unjustified to me. I am getting ready to build a new house and I am not sure that I can justify the cost of a variable speed heat pump over at 2 stage AC and conventional gas heater.

[@marklahiff4319]

Maybe this will drive contractors to do a manual J calculation for residential customers. This calculation provides the right size equipment. Contractors near me always oversize. I didn't know that SEER 2 was coming but replaced both furnace and air conditional. I searched a lot to find someone that would do this calculation for me. I told them I was willing to pay. Everyone just said a ton for 500 sq ft. I ended up with more like 850 sq ft per ton. I'm going to have to wait at least one more year to see if my AC is undersized. We only had three 90 degree days this year and not one 91 or over according to Detroit metro.

[@josephgriffin1065]

[@anthonylosego]

If you get a communicating unit, it can run as low as 30% capacity, which can "auto adjust" for oversizing. It's also quite a bit more efficient that way. Like always driving 55mph or lower. When aerodynamic effects go exponential with speed, you have to waste a lot of fuel to drive a car over 55mph. Same with compressors, cycling times, and blowers. My 3 ton unit barely pulls 12A most of the time and keeps the swings extremely low. So going communicating can let you oversize and also have a less tight system. Not ideal, but what ever is?

[@johnhaller5851]

Most people do a lazy Manual J. To do it properly requires information mostly not available after the building was built, and sometimes not even then, including the R-value of the insulation in the wall, the U-value of the windows, and the results of a blower door test. You can find Manual J calculators online, just to look at the kind of input required. Manual S is used to pick the right equipment for the home. Then, they should also do a Manual D to ensure the ducts are sized properly for the selected unit. But no, they will reuse the existing ductwork because no one is paying for new ductwork. In my last house, the return was way undersized, and the poor unit was trying to suck through a straw that was too small, and getting extra air from any hole it could, and the basement was a low pressure zone. Now, to get a permit for a new house, you need to have window specs (among other things) to do the J, S, and D calculations to be sure there is enough space for ductwork in the framing. Typically, a blower door test is required to show air leakage meets the design. A maximum for air changes per hour (ACPH) is 5 to meet International Building Standards. A really good house is under 0.5 ACPH.

[@thewisecracker-rq1pu]

This isn't rocket science. It's always better to slightly under size rather than over size. You want it to work and remove the humidity rather than just cool it off quick and leave it cold and clammy. Also, manual J never takes into account the fact that it is calculated with an empty house when in fact most houses are at least half full of people's stuff which makes a huge difference. SEER 2 is BS, it's the same equipment, just rated differently depending on where it is installed. Modulating equipment is the way to go for larger homes if you can afford it. Bosch makes high quality modulating condensers and I highly recommend them.

[@AudioFanMan]

Manual J does account for occupancy, and in addendum A (Manul J dos and donts) its supposed to be bedrooms +1 so a 4 bedroom house would be 5 occupants. And those occupants should be located in the home where they might be on a design day about 5PM not necessarily the bedrooms. @@thewisecracker-rq1pu

An R-22 refill is close to the cost of a new basic condenser for anyone who doesn't know, but In trying to research what other refrigerants I could DIY use to replace R-22, I found out that they make direct-replacement refrigerants since R-22 is basically nonexistant anymore. The names are weird, like R407a or something not easy to remember, but it's a way better option to repair a leak and use those than replacement units if the condenser is still solid.

@@Demoralized88 You could DIY maybe, but you have a leak, do you have the means to trace the leak? Do you have the equipment to recover the remaining charge? You cannot repair a leak with refrigerant still in the system, and you cannot legally vent it. So you found the leak, where is it? is it a copper to copper joint? or is it copper to aluminum joint? Can it be re brazed without damage to other components? Do you have the tools needed to fix it? If you fixed the leak, Do you own a vacuum pump and a micron gauge to evacuate the air and moisture after the repair? How will you recharge the lost refrigerant after the repair? Buy manufacturers weight? Or will you go by super-heat, or sub-cooling charge methods? do you possess the instruments and knowlege to use either method? In my 36 years of HVAC I would say R-22 is generally the best residential refrigerant, but the commies outlawed it, and the last 30 lbs. jug I purchased was just under 1700 bucks, R-410A was the replacement and it was billed as (("eco-friendly")) but the commies have now decided its not. So starting in 2025 we will switch to the new (("eco-friendly")) refrigerant until the commies decide its not. So yeah its expensive, but don't blame it on HVAC contractor greed, blame your communist government.

[@Demoralized88]

Did they happen to install (upsell) a whole-house Humidifier when you bought the new Condenser? Mold growth in the ducts ain't normal for even the preposterously oversized units that HVAC companies use, as even pretty low duty-cycle AC will remove a good deal of humidity. I very much doubt your install was done correctly, and you likely have a humidifer running, EVAP drain clogged, or some other problem from the install. My guess is that they screwed up the condensation drain or something on the Evap Coil, and you probably have water pooling in your furnace. Mold doesn't start forming everywhere even if you had the windows open constantly and no AC, so you MUST have water being ADDED to your system from something like mentioned.

[@davidgapp1457]

We have a single level house in Phoenix, Arizona. The 2 HVAC unit are nominally SEER 14. However, the duct work in the attic is a disgrace. ALL of the insulation is flexible hose rated at R-6. How much you ask? Well, I painstakingly measure it. We have, for our 2,750 sq ft house, a total of 186 yards of ducting. Keep in mind it is quite normal for attic space in Phoenix to range between 120 and 140 deg F between the months of June through September. When you crunch the numbers, and assuming a target temperature of 80 deg F, more than 1/3rd of the energy used by the HVAC is lost directly to the attic space. In peak months, or if you lower the target temperature, the losses are worse. Much worse. Set a temperature of 76 deg F and almost 1/2 of the energy is lost to the attic. That HVAC engineers, during construction, are allowed to install such a shoddy system is a simply wicked. Chalk it up to almost non-existent building standards. So what did we do? Well retrofitting the house with internal ducting (ducting that is inside the cooled space) was impractical both from a cost and engineering perspective. So what we did was install SEER 23 mini-split systems to all the closed spaces (such as bedrooms, office, bathroom areas). Then we simplified the ducting in the attic and finally installed a single, top tier Carrier Infinity system (nominally around a 22 SEER2 solution). We then insulated the remaining ducts using R22 lagging. This was an affordable solution, not least because I installed all the mini-split systems myself. The net result was that our total electric bill for the summer months was slashed in half, meaning the HVAC component was cut by more than 60%. Not only that, the Carrier is a very, very quiet machine. The original Goodman units (2 of them rated at 4 ton each) were positioned directly outside two of the smaller bedrooms - the noise was unbearable. By comparison the Carrier runs almost silent and loses the unpleasant 'start up' noise guaranteed to wake the dead. It is painful to speculate how much energy is wasted in Arizona every year. I wish our house were the exception, but really it isn't. However, a 2 level house will always be a much better proposition for the same square footage, because at least half the duct work will be internal (but often more). Single level house in Arizona are a disaster. As for SEER2. Well from an Arizona perspective, the numbers are still something of a joke. It is frustrating that WWII era technologies are still allowed. When will we join the 21st century I wonder?????

The attic is A frame so to make any difference we'd need to insulate between the roof tiles and the A beams, with some kind of lining to keep the foam in place. I would be interested to know how you did that. Also, the ducting is flexible hose, suspended by straps, from the A beams. I've discussed with builders what it would take to resolve the problems.

Maybe at the 10 year mark you have enough loss through permeation to get a couple ounces of top up, but leaks shouldn't happen with a good install. If you really worry about not being able to get a few pounds of 410a at a good price, 454b is so close to 410a in volumetric capacity and everything else that units coming out now can be retrofitted with just a different expansion valve brazed in and could even get away without that change.

If you want something that is bare bones and not so efficient, but will out last the life of the house...then that model over there is for you.

I was going to install central AC in my home, but after doing my research, I'm sticking with window units and remodeling my kitchen instead. Central AC seems like it's way too complicated and expensive.

Thank you 10% Joe

The increase in size of equipment is a problem that they should have considered. It's not just HVAC equipment, it's water heaters too

[@sewerrat7612]

Always fun when you have to get your guys to reframe a room because original barley fit. Feel so bad for those customers.

[@bad05ford]

Increased efficiency is moot when the unit cost is 2-3x and the reliability is non existent. Then you get 5yr down the road and need 8k in repairs or another 30k for a unit.

[@jimharper2604]

I built my own home and did geothermal. Additionally, I designed the system so that there was ZERO ductwork in the attic. No loss, no gain....

[@mikahundin]

Seer2 is a new standard for measuring the energy efficiency of HVAC systems, based on the M1 testing procedures that account for the ductwork and external static pressure. This means that the HVAC industry had to redesign their equipment to meet the new requirements, which resulted in larger, more expensive, and more difficult to install systems. However, it also means that the Seer2 ratings are more realistic and accurate than the old Seer ratings, and that the systems are more environmentally friendly.

[@funnycatvideos5490]

is it really more environmentally friendly you have to change it out more often?

[@massa-blasta]

I am in South Louisiana and do not trust the SEER2 rating, in this heat. Old R22 units are far superior for cooling. Better energy efficiency is great, but not when you sacrifice the ability of the device to provide adequate cooling in hot temperatures.

[@integr8er66]

So what you are saying is the systems just have to be over sized. Not that they can't cool, just that the ratings are not consistent with older units. So in short it doesn't save a damn thing, and it costs more money

[@____MC____]

My only complaint is the size. Most access holes are barely big enough. Always have to remove sheet rock and its risky spreading the trusses.

[@keything8487]

can i still buy a seer 1 cond unit/AH ? are they cheaper? i'd guess supply houses wanna move that stuff so they dont get stuck with it. and i;d like to have it sitting on my shelf until i need it?

[@JesseDoesHVAC]

Just wait. Here in Australia 🇦🇺 we have MEPS (minimum energy performance standards) of which dictates that you basically cant sell a non inverter system in residential.. that and r32 taking over

[@gpny]

I enjoyed your video and am subscribing. I was wondering if you service and install pool heat pumps? We have been studying the Texas market and find it quite far behind some other markets when it comes to pool heating and cooling

[@jamesphillips2285]

Wait: how did you get the "like" button to light up at around 0:44?

[@6barry66]

Seer 2 is not the enemy of consumers. I live in New Jersey.We have hot summers that are humid. Anything that is not seer 2 Compliant will struggle on hot days to cool and dehumidiry. Any price increase that consumers incur is due to the greed of the contractor, not the cost of the equipment. Seer 2 decreases service calls and lowers utility bills. That may be bad news for contractors , but it's good news for consumers. The enemy to consumers is contractors, not Seer 2.

[@robertsmith2956]

Was hoping to find out which is better. A seer 17 of a Seer2 15.

[@Joepacker]

Glad I got our HVAC system replaced back in 2017 before all this happened

[@sylvester2294]

As always the consumer foots the bill ...and it gets worse...the cost of repair!! Circuit boards with variable speed drive for the compressor adds complication...Same for variable speed blowers.

[@robertroy6094]

What does "soft start" do for efficiency? Does it help with power consumption?

[@phillipsusi1791]

No, it doesn't help.

[@alanmorrison3598]

All these changes are mandated by un-elected bureaucrats and just like mileage requirements for cars and trucks, result in lower reliability, higher costs and many times higher overall carbon footprints if that's what you believe in even though there is no scientific consensus on this issue. Just try pricing out some of these high end variable speed motors, inverter drives, control electronics etc. Maybe defund the DOE and the EPA and let free markets dictate!

[@porterhouse131]

Damn, I’ve been doing AC since 2016 on my own and how do you know there was a SEER2 it didn’t reach me in the slightest only thing that reached me was a chip shortage right after Covid.

[@robertsmith2956]

Wow, it was all over the AC supply web pages from the fall at least. Jan1st changes in big print....... Maps showing the areas and whet seer2 they needed.

[@scoobtoober2975]

Holy smokes. Thanks for the info. I had no idea. Now i know why i can't get a 17.5" 100kbtu unit. or is mine just 80k all along? Goodman 92% 15 years old. doing a full dual fuel swap

[@progressreason_1]

Great video explaining HVAC progress forward

[@chazman4461]

How about changing the US building code to build better houses and buildings. We do this and develop equipment that has less reliability like the end user has money to throw away replacing parts every so many years. We are seeing it now with kitchen appliances not making it 5 years.

[@JoeKubinec]

Just a homeowner here... awesome video... I learned a lot. Had no idea of the potential impacts related to unit size and changed efficiency standards. Back to window units when my system eventually craps out!

[@josephlownes5138]

Does seer two apply to the window unit to

[@cobbles62]

What about the elephant in the room? The higher seer ratings need variable speed stuff. I'm guessing that most of the current generation of HVAC technicians understands the simple circuitry that includes a couple of relays and capacitor while "2 speed" components, although still 1920's electrics, are already seen as state of the art. But they are most likely completely out of their depth when confronted with variable speed brushless fans and compressors, inverter boards, NTC's and PID logic. Many mainstream hvac specialists just don't sell variable speed stuff, some only do it "under duress" while throwing some scare tactics in the mix. A car analogy: At this moment we are living in a world where cars are stuffed full of electronics, but where mechanics only know how to apply sand paper to the ignition points of a model-T

[@toddward3855]

Just an FYI I contacted your company for an 4 Ton HVAC replacement in DFW two weeks ago and never got a response. Might want to make sure someone is checking your website inbox. Y'all's pricing is highly competitive, so you may be missing out on a lot of revenue from that avenue.

[@petebusch9069]

The install cost of a new AC or furnace is what we should be talking about.

[@erickanorris567]

around here many people have to have new units brought in with a crane . $$$$$$, I've seen houses with 8 inches between the ac and the masonry fence

[@Phil_Scott]

I see a lot of smart ideas in the comments... and ways to cut repair costs to zero! You can save all that by placing the window ac's next to the driveway side of the house... that way when it dies you just call the dealer and have him park his truck under the window... and shove it out the window. There are wind drift problems with that on taller buildings over 40 stories though. Its complex. I have no idea what we are going to about all those people breathing out all that poison C02 gas though.. maybe recirculation using a high pressure micro blower and a rectal tube would work. I am 83 now and am completely impressed by all the new advances, especially the new WIFI toilets that snap closed when the power goes out.... all we are missing now is the wire brush bidet.

[@SoullessProductions]

The higher the seer rating means the higher the price point of the unit and the less likely it is to last longer than the warranty
