Hey guys wanted to do a video on dual fuel versus straight ac and furnace, and maybe uh, you know you're considering what is the best for your home, and i believe there are four things that would affect your decision or or at least things you should consider Before you decide whether or not you go straight ac with furnace or dual fuel, and so first of all, what is dual fuel dual fuel? Basically, all it means is the outdoor unit, instead of being a straight air. Conditioner is a heat pump, so it can do air conditioning and heat with the outdoor unit, and then the furnace becomes the back up heat so meaning if it's super cold outside you'll be burning gas. If it's mild outside you'll, be using the heat pump and saving gas, and so i believe again, there's four things and, let's run through those four things, real quick. The first thing is, would be price if you're, considering dual fuel versus straight ac and furnace.

Typically, if you're, comparing apples to apples across the board, dual fuel is going to cost a little bit more. The outdoor unit, the heat pump, costs a little more than a straight air conditioning condenser and there are components that need to be added like outdoor temperature sensors. Possibly in the old days we used to use external fossil fuel kits, but these days we would just use a thermostat that can control the dual fuel capabilities, and so you might have to do an upgraded thermostat with that sensor, and so that does affect the price. A little bit across the board, typically you're, going to be looking at a little bit higher price for a dual fuel system than just a straight furnace with straight ac, and so that would be the first thing.

The second thing would be heat rise. You have a heat pump, the heat rise, meaning the temperature it's going in the return and the temperature coming out of your vents is going to be lower. It's going to be a lower heat rise than if you're burning gas or a fossil fuel. So if you're burning gas you're going to get a higher heat rise, you're going to get a higher temperature difference between the two, so you might see a 30 or 40 degree heat rise with a furnace.

It might be going in the return at 70 degrees coming out at over 100 110 degrees, whereas with a heat pump, you might only see a 20 or 30 degree heat rise. So just keep that in mind. Another thing that might affect your decision is: what type of gas do they have? So if you have lp or propane it costs fluctuate, you have to get it delivered to your home in most cases, and you have to worry about the price of propane or do you have natural gas? Historically, natural gas has been a less expensive option than propane. You know you'll have pipes coming to your home with natural gas, typically from your city or some sort of utility company and you'll be burning natural gas and it's less expensive than lp.

So again, if you have natural gas, you might be less inclined to do dual fuel than you would be if you had propane, if you had propane, you should definitely probably consider, at least in our market, definitely consider dual fuel and the last thing. The fourth thing that should affect your decision is what type of climate do you live in and what i mean by that is, if you're you know somewhere in the middle of of the usa, you know somewhere where it's. You have some mild days more mild days across the year than super extreme temperatures. Well then, you might consider more of the dual fuel option because you don't want to be burning gas on a mild day.
You know it'll just be running off of heat pump. You'll be saving gas on those mild days, you'll be saving that money, whereas if you're in a more extreme temperature, if you're in the northern part of the us, if you're up in the canada places like that more cooler temperatures, you might be less inclined to do. Dual fuel: i have seen customers up that way, have dual fuel as well, but you might be less inclined to do dual fuel and more inclined to just burn gas because you have less mild days in general anyway, so the savings might not be there anyway. I hope that helps if you're, considering dual fuel or just straight ac, with furnace in your home.

    Nice video I learned some things, I personally rarely have come across dual fuel setups in my service area (also still a newer tech). Pretty much see NG furnace or boiler, or all electric. The few dual fuel setups I've seen seem inefficient, even on a slightly colder day still seems more cost effective to run gas furnace opposed to heat pump. Not too familiar with defrost in these applications, what is a good setting to lockout the heat pump (40 deg?). Having furnace coming on during a defrost cycle seems like a waste and short cycle potential.

    Thanks, Good info!!! Regarding your "through wall fan" vid, What do you do about the positive pressure to the room? (im guessing you ignore it because your only pumping approximately 100 cfm ) any info/advice is greatly appreciated. !

    I'm from Québec and I'm checking to change to a furnace with natural gas and a heat pump..I'm waiting for all hvac guys to show up but the first one give me a estimate of almost 30k for all instal…I don't have duckt and no natural gas…so a think this is a reasonable price 🤷🏼‍♂️
