Thanks for the informative presentation. Remarkable how the EER never seems to improve. I have an 18 year old R-22 system rated 12 SEER and 11.5 EER. 18 years later and we are still quoting specs of 11 EER. Just goes to show how meaningless SEER is as our utility bill is driven by EER.
Thank you sooooo much for this video! I'm in need of a new furnace an a/c unit in the northern region and your video was exactly what I needed. Most videos beat around the bush but you CLEARLY stated the new regs! It may be confusing but by showing on the screen AND you explaining at the same time made it much easier to understand. Many thanks!
The conversions used in HVAC efficiency metrics, such as those between SEER and SEER2, or EER and EER2, are indeed close estimates rather than exact conversions. These conversions are intended to provide a way to relate older metrics to newer standards after adjustments have been made to reflect changes in testing procedures or regulatory standards. The conversions are practical tools for comparison but should be understood as approximations rather than precise mathematical equivalents. System Type Application: • Category 1 (5-ton ≤ SEER/SEER2): Typically, SEER and SEER2 are the relevant metrics. If the system is a heat pump, then HSPF/HSPF2 would also apply. • Category 2 (5-ton > EER/EER2, IEER): For larger systems, EER, EER2, and IEER are more relevant. If these systems are heat pumps, then HSPF/HSPF2 and COP/COP2 would also be considered. Equations: 1. Cooling a. SEER & SEER2: • Seasonal Energy Efficiency Ratio (SEER) • Seasonal Energy Efficiency Ratio 2 (SEER2) • Conversion: 1. SEER = SEER2 × 1.045 2. SEER2 = SEER / 1.045 3. SEER = EER / 0.813 b. EER & EER2: • Energy Efficiency Ratio (EER) • Energy Efficiency Ratio 2 (EER2) • Conversion: 1. EER = EER2 1.04 2. EER2 = EER / 1.04 3. EER = SEER × 0.813 c. IEER: • Integrated Energy Efficiency Ratio (IEER) • Conversion: IEER=(0.02×EER@100%)+(0.617×EER@75%)+(0.238×EER@50%)+(0.125×EER@25%) o Example EER is 11: EER at 100% load = 11.0 EER at 75% load = 13.9 EER at 50% load = 18.4 EER at 25% load = 19.1 IEER=(0.02×11)+(0.617×13.9)+(0.238×18.4)+(0.125×19.1) IEER=0.22+8.5763+4.3792+2.3875 IEER= 15.563 IEER=~15.6 2. Heating a. HSPF & HSPF2 (Heat Pumps Only): • Heating Seasonal Performance Factor (HSPF) • Heating Seasonal Performance Factor 2 (HSPF2) • Conversion: 1. HSPF = HSPF2 × 1.18 2. HSPF2 = HSPF / 1.18 b. COP: • Coefficient of Performance (for Heat Pumps and sometimes Chillers) • Conversion: 1. COP = HSPF × 0.293 2. HSPF = COP / 0.293
For your graphics: it would be helpful if you would put what category you're talking about on each page: Air conditioning units, heat pumps, package systems.
Is it normal for the unit to consume electricity even if every indoor unit is off? Mine consumes .9A. I had someone install a 3-head, 36,000 BTU mini split.
Why are the new SEER2 ratings generally lower than the old SEER ratings? If the new requirements are more stringent and intended to increase efficiency, it seems to me like the new SEER2 ratings should be higher than the old SEER ratings. What am I missing or not understanding???
First off you know its probably a lot more complicated than what they are telling us. If the box says it that what it is! LMAO This will all work out in a few years when we forget completely about the Old SEER numbers and everything is up to the new SEER2 standard. This sounds like it started in California..... This is complicated Its more like come back in 2025 and see if this even matters! From what I gather with AC it pretty much all has to do with the increase in the static pressure... where the MFG's used .1 static pressure to calculate SEER they will now be using .5 to Calculate SEER2 and this .5 static pressure will represent the 'real' world and how air moves through the system. In the field when do you ever get a .1 ? After that I have no F**kin clue what is going on!
@@cow7boy seer2 is a harder number to hit. That's why the requirement is lower. It's like if you needed a certain amount of home runs to qualify for an award, they can say you need 40 at a 350ft distance, or 33 at 380ft. The same skill or better is needed to hit a lower number at a greater distance.

Awesome to hear! Thank you so much for your comment!
Thanks for your Clear Explanation of the new SEER rating for Each region... In the Southeast is little confusing 👍
Extremely helpful. Thank you.
Explain how you can tell what the BTUs are for your air conditioning units.

For larger systems, EER, EER2, and IEER are more relevant. If these systems are heat pumps, then HSPF/HSPF2 and COP/COP2 would also be considered.
Equations:
1. Cooling
a. SEER & SEER2:
• Seasonal Energy Efficiency Ratio (SEER)
• Seasonal Energy Efficiency Ratio 2 (SEER2)
• Conversion:
1. SEER = SEER2 × 1.045
2. SEER2 = SEER / 1.045
3. SEER = EER / 0.813
b. EER & EER2:
• Energy Efficiency Ratio (EER)
• Energy Efficiency Ratio 2 (EER2)
• Conversion:
1. EER = EER2 1.04
2. EER2 = EER / 1.04
3. EER = SEER × 0.813

• Integrated Energy Efficiency Ratio (IEER)
• Conversion: IEER=(0.02×EER@100%)+(0.617×EER@75%)+(0.238×EER@50%)+(0.125×EER@25%)
o Example EER is 11:
EER at 100% load = 11.0
EER at 75% load = 13.9
EER at 50% load = 18.4
EER at 25% load = 19.1
IEER=(0.02×11)+(0.617×13.9)+(0.238×18.4)+(0.125×19.1)
IEER=0.22+8.5763+4.3792+2.3875
IEER= 15.563
IEER=~15.6

Great vid and info!
Thanks so much Dave! We are so happy you enjoyed our video.
I live in sacramento what system is going now?.my house built 1989 with ac and furnished system
Thanks, that was helpful.

These are the bare minimums. The bar to qualify for federal tax credits is even higher.
This is all for bottom feeders looking for the cheapest install price. Factoring in operating cost, there is no reason not to get a 19-25 SEER system!
Great advice! Now you can make up the cost difference for all us bottom feeders so we can all have SEER 25 units!
