In this video, Joshua Griffin share what exactly is an inverter HVAC system, and why more homeowners today are considering having one installed in their home than ever before. Being the future of the HVAC industry, Joshua talks about the origins of the technology and why he considers Daikin the best at producing HVAC equipment to his customers. Lastly, Joshua discusses the misconception homeowners may have when comparing HVAC systems and how it can be confusing when comparing inverter, VRF, VRV, and variables heating and air conditioning technologies.

What Is an Inverter System We've done videos on these inverter systems and different verbages. We're going to talk about some of those. But if you are in the market for a heating and air system and you keep hearing this, what's an Inverter? They keep talking about inverter systems. We're going to talk about what exactly they are, why you should care as a homeowner, and why it really is going to matter as time goes on.

So first my name is Josh I Host the HVAC guide for homeowners YouTube Channel Let's Dive Right into this: What Is an Inverter System We hear all kinds of folks saying inverter Vrf Vrv Variable Speed Compressors All these different verbages and they all ultimately I know there's different Technologies out there with communicating and non-communicating But ultimately, if somebody says they have an inverter system is a system that has a compressor that can ramp up and down. Now again, some use different Technologies to make that happen, but ultimately you've got a compressor instead of a single stage system that runs full speed or off, or a multi-stage system where there might be in-betweens An inverter system is going to be able to ramp up and down based on the load based on the technology that's in it. Some systems are simpler than others where they just monitor the evaporator coil temperature. Some of them are a little more advanced and they can actually measure what's the outdoor temperature.

Hey, it's kind of a mild day. Let's just barely run today and save this customer energy. What folks are finding is when they're comparing systems and they're looking at things like Seer ratings and Eer and Hspf and all these different ratings. They're not always a good, accurate representation of how efficient a one system is going to be to another.

Meaning, you might have a system that has just as high of a Seer rating, but if it's a non-inverter system, it's not actually going to be as efficient as some of these inverter systems. Inverter systems have the capability of at times just barely be running. It's almost like a dimmer switch that you see on some lights. Where that dimmer switch can bring that light way down.

that lights just barely drawing any electricity. And in the grand scheme of things, saving the homeowner tons of money. Now let me throw a couple things at you that you may not know. The first thing is a lot of terms like variable speed.

Things like that are being thrown around. Some cases it confuses folks. A lot of contractors will say variable speed system. What they're really alluding to is the indoor fan motor is variable speed.

It does not necessarily mean you have an inverter, Vrf, Vrv type outdoor unit, or even a compressor that has the variable capabilities or inverter capabilities. We've seen variable speed air handlers or furnaces be matched with a single speed outdoor unit. Now Does it make it a little more energy efficient? Yeah, a little bit. but it's not the same thing.
Just be aware of that if somebody throws around terms like variable speed, they may not necessarily mean an inverter system, especially a communicating inverter system. Next, let me also point out that a lot of contractors, even some that might comment on this video, are very wary of using them. They'll even fight you, in some cases, tell you that it doesn't make sense in their particular area for one reason or another. they are putting up a fight.

Some contractors just simply won't install them yet. And the reason I say yet is because inverter systems are the future where we're going. We don't need eating roads. I Believe Over the next decade you're going to see the U.S Market especially.

But the North American Market really take hold with inverter systems like never before. Where The Wild West if you will when it comes to this technology. Got any of you have the guts to play for blood? I'm your huckleberry because if you go outside of our continent, other parts of the world, they only have inverter systems because they're so efficient in. America We like our gas guzzling cars and we like our ducted single speed air conditioning systems.

Other parts of the world are way ahead of us on this. So I Believe In the very near future, you're going to see not just more inverter systems being sold, you're going to be seeing some contractors only offer inverter technology. You're going to see some homeowners that only want inverter systems installed and these contractors that have not come along that they have put up this fight and tried not to install this technology that they may get left behind. Do I think they're left behind know they'll just eventually have to get with the program right? I Will say as you navigate through this that one thing we are also seeing is this whole Market of folks that do single speed and multi-stage systems.

But then you've got this whole nother side of folks that know that inverters are the future, but they're all trying to pretend that they're all the same and they're just not We at Griffin Air we saw Daikin for example and Daikin is the best in my opinion at inverter technology, they're leading the way. In fact, they created the technology decades ago, back when I was a small boy over in Japan I wasn't a small boy in Japan I was a small boy here in America But they created the first Vrv system over in Japan and even now they've got the dike and fit. They've got the Vrv life and they've just got all these different systems that have technology that no one else has and that's part of the reason we sell them. We mostly sell them because they're how reliable they are.

But even if you don't go diking and you go with another brand, just realize they're not all created equal. Do your homework, find a good contractor that has installed them. You don't want to be anybody's guinea pig foreign. And now with all of these government rebates and incentives to install these higher sear systems, these inverter type systems, you're going to see a massive shift in this market to more contractors offering them and again more homeowners looking to purchase them.
I Had somebody comment and say Josh you keep talking about inverters I don't even know what they are. That's what they are in a nutshell: A System that can ramp up and down and save you money. so I hope that helps. Thanks for watching Hit that subscribe button.

We'll see you next time.

    Are there any inverter systems that would work with a Nest based system? The communicating thermostats are outrageous. As I have zoned system, that twice the outrage.

    For me less electronics the better I'll go for the mechanical system period…you will save money on electric…but spend 10 times more for repairs and maintenance. Service area Nepean??

    I think the problem right now is most manufacturers see inverters as a reason to charge way more than the standard system even though it might only cost 5-10% more to make. To its credit, Daikin Fit isnโ€™t too pricey, but all the big American brands treat inverters as a Lamborghini

    100% accurate… Had no idea what the difference between inverter and variable speed… Had five different companies come out and none of them would suggest going with an inverter system, saying they were just overpriced/ overhyped equipment.

  6. Avataaar/Circle Created with python_avatars Garth Clark says:

    I've always wondered why our USA AC electric doesn't get "inverted" to DC at the point of entry for residential. DC current is a constant sine wave and more efficient with motors in general.
    I also say the same with the Cable and Satellite industry, why not put the "box" at the point of entry of residences and then let the tuners that come with the TV's or other devices use their own electronics to display the many channels. I can think of many reasons that is reasonable but one is saving the power each TV box must use because each TV location has to have the decryption of the signals and for that, a lot of these boxes are using 100 watts each.

    I do like the idea of DC operated HVAC as the efficiency is much better however, where is the natural gas condenser these days? Those seem to be even more efficient in cost to run.

    Also, we need to look at the cost of maintenance for these inverter systems….A $200 AC 220v blower motor is about $1,200 for inverter type. Compressors are more expensive too and then there are all of the "electronics" with inverter systems that will fail along the way and they are all proprietary and expensive vs. "universal" parts inexpensive.

    The issues to overcome with more complicated/higher seer/more efficient systems: The cost has to make sense- upfront cost and maintenance cost. Two years ago a friend bought a 3 ton Lennox split system with a XC16 2 stage cool 16 seer A/C and a SL280V 2 stage heat variable speed gas furnace for $8000. Great deal, but if she bought the XC 25 (22 seer) A/C, then it wouldโ€™ve been $14,000. Maintenance cost are way higher on the highest seer rated A/C because of needing to replace the computer circuit boards and other expensive parts after a period of time.
    Technicians need proper training to install/set up/program the systems. They didnโ€™t even program her gas furnace to put out the right amount of airflow. Left it on factory settings. There are 12 speeds for cooling and 12 speeds for heating. Need to have Wi-Fi in the house for communicating systems, not everybody has it.

  8. Avataaar/Circle Created with python_avatars Anthony Spadafora says:

    An inverter heat pump takes incoming a/c current and runs it through a bridge rectifier to create a very smooth DC current, that DC current is then put through a simulated 3 phase AC inverter which is can be started without start windings and its speed can easily be controlled. This is why a 2 stator generator that produces dirty AC can be used on an inverter, it is going to be rectified anyway.That is the compressor, the condenser fan is controlled differently. Some are DC being powered off the rectifier, some are just multi speed AC and others are simulated 3 phase just like the compressor. Hence All inverters are variable speed but not all variable speeds are an inverter. There are units, particularly the ones that run off of solar power that are DC and actually use a DC compressor. Inverters today are very good, surpassing 95% efficiency but even that 5% is too steep a loss for solar powered units. I think the biggest hurdle for manufacturers to go to all inverter units is the simple fact they spent the last 35 years tooling up for scroll compressors. This took quite a while as they were still selling piston style compressors in 2010 and maybe later. They are not having any success at varying the speed of scrolls which makes them unsuitable for inverter drive motors. Now rotary compressors are being used, the rotary is not new, they have been using them in refrigerators for decades but for some reason not in AC systems. So now they will have to retool to build rotary compressors. Hopefully with the new CNC machinery available today it doesnt take 35 years to do this. Even the best vapor injection units found on the Mitsubishi are rotary.

    When they become more widely accepted would be the time to look at these. Who cares what other countries are doing? Normally lagging in every measure. More sophisticated systems are more expensive & a lot more costly to repair, normally never getting enough saving to justify the cost!

  10. Avataaar/Circle Created with python_avatars bob boscarato says:

    Hello Joshua; great explanation; I'm considering replacing my existing system with a 3 ton HP about 16 SEER.- 2 years ago I purchased a Panasonic Microwave oven and supposedly has inverter technology. It has no compressor, so I figured they used the word as a "silly buyer magnet". Buyer beware! Are you in Ottawa ?

  11. Avataaar/Circle Created with python_avatars YeeeBa YeeBa says:

    I used to like you, but i like my 6.7l coal rolling 8 mpg truck better. I will also try to keep the most energy consuming a/c system available. The day i sacrafice being comfortable over "climate change" nonsense will be the day im 6 feet under.
