Howard, you really nailed it with this video! Your deep understanding of HVAC systems shines through as you break down the complexities of EER and SEER ratings in a way that's easy to grasp. I appreciate your honesty in pointing out the flaws in the rating system and how bureaucratic hurdles can sometimes get in the way of rebates for high-efficiency systems. Your passion for helping people make informed decisions about their air conditioning needs is evident, and it's clear that you're a true HVAC pro. Thanks for sharing your expertise!

Thanks for that Marcus! I really appreciate your kind words. Here at The Bee Heat and AC we strive to provide excellent HVAC knowledge. Glad we were able to help.

[@TheHVACDopeShow]

Thanks Marcus!

Daikin Fit 100% !!!!! After researching for the past 6 months, reading online and watching hours of videos I'm sold on Daikin Fit and wish you were in Florida. The moment my system takes a dump I will be going to Daikin. You put out great informative content on everything HVAC and having watched all your videos I truly believe Daikin is probably the best unit for the money. I have learned so much from your videos and thank you for your dedication to your field.

[@Balticblue93]

By far one of the best choices available on the market and I also recommend this to a good portion of my clients.

[@TheHVACDopeShow]

Thank you Richard, this really means a lot. And you might see us in Florida pretty soon!

[@TheHVACDopeShow]

Yes!! Daikin is our preferred brand of choice due to its quality, warranty and price.

[@richardsmith4187]

That would be awesome and lots of HVAC work down here and not enough qualified people to do the work.

[@The1JBanks]

Solid video keep up the good work!

[@TheHVACDopeShow]

Thanks, will do! 🙌

Technically w/ Heat Pumps people will be running their unit more than a typical AC only.

[@TheHVACDopeShow]

This is definitely true! You’re referring to the condenser right?

[@rcinfla9017]

Reason why mini-splits have lower EER is because the inverter power supply that creates the variable frequency three-phase electric drive for compressor speed control has additional electric power loss, around about 10% loss at full power. Mini-splits usually have smaller outside heat exchanger condenser size also reducing their peak btu EER efficiency. They compensate for this a little bit by running lower subcooling on condenser and superheat on evaporator side with all the temp sensors controlling compressor speed and an accumulator to help protect compressor from return liquid refrigerant flooding. Electric utilities care about EER because they have to supply the peak electrical load demand in hottest part of day when most of A/C's are running near their maximum output and highest ON duty cycle. Smaller btu and cheaper mini-splits also often have poor power factor with high peak current crest factor that electric utilities do not like.

[@TheHVACDopeShow]

That makes sense especially on the cheaper mini splits. Thanks for the comment that was very detailed and well explained! On the hottest days our inverter units typically don’t run at peak capacity though which is why it’s boggled my mind. I’ve watched the systems (daikin fit and VRV) modulate and maintain setpoint at 30-50% capacity (ballpark based on ampdraw). That’s why the EER seems flawed to me because if a unit rarely hits 100% capacity then using it’s EER to guess how much power something will consume seems like not the best approach

[@sullydee2237]

do you know of a 5 ton 5 zone head on wall 6k or 9k unit that is close to 30 seer .mitsubishi unit or other hepf 10/13.5 / try to save on running cost

[@TheHVACDopeShow]

Some of the Mitsubishi stuff goes up to the 25 SEER range, I’m not sure of anything in the 30 SEER range but I’ll look into that more!

[@TheHVACDopeShow]

Daikin Atmosphera is up to 27 SEER, but that’s a single zone. Daikin Mxs series is up to 21.7 SEER. Mitsubishi has a few products in the mid 20’s for multiport as well.

Can’t believe the govt would be so out of the ballpark on this. Would like to better understand their rationale.

[@TheHVACDopeShow]

Yeah I’m just as lost… but I really believe it’s just them being bureaucratic and inept because our local utility XCEL gave rebates for single stage heat pumps because they had higher EER ratings than inverters, but that’s because the EER ratings on inverters account for max capacity and max power consumption and that’s not when inverters are efficient or even how they run. They barely and rarely hit 100% capacity maybe for a 5% or less of their run time even in super hot cities because as the temp gets closer to the set point inverters will run at 10-30% capacity to just maintain temp, which is why their SEER ratings are higher. Idk it’s kind of weird lol but I know that currently a lot of manufacturers are lobbying to change this.
