re: AC Unit Question

We are all electric with no access to natural gas. 16 seer AC without the heat pump should be fine then I guess. 16 seer should lower the electric bill versus the 14 seer.
What are you going to heat with?

Ask your AC man to compare the actual capacity and efficiency between the 14 seer and 16 seer units. The 16 seer unit is going to be considerably more expensive but you will likely find that the efficiency and capacity difference between the 2 is going to be very close. The S/T ratio is another factor to look at. That is basically the dehumidification factor. Want the one with the lower one meaning better dehumidifation. And must get a 10 year warranty. Make sure he registers equipment to insure the 10 year warranty, I think the 14 seer might be the better buy after all comparisons. Good Luck!

A heat pump can only heat a house when the outdoor temperature is around 40 degrees. When temperature goes below 40, you need auxiliary electric heat strips. You can also chose to go with a standard AC unit and straight electric heat strips for heating.

How often will you run your heater in South Louisiana? Wife and I seldom run the heater.
Heat pumps are more complex than regular system with best strips. More wear and tear on the compressor. Simple heat strips is the way to go unless you keep your home 85 all winter.

You don't need to be looking at SEER rating, you need to look at tonnage. The SEER rating is efficiency, tonnage is capacity.
Also, natural gas is common and plentiful; there's no need for a heat pump.

So when your electricity goes out, what powers your thermostat, provides the power for your blower motor, etc? Gas or no gas, no electricity means your heat source isn’t going to keep you warm.
True, but the blower of a gas furnace can be powered with a very small generator, I run mine off a Honda EU2000, you cant do that with a heat pump or other type of electric heat.

If I lose power during the winter, my generator kicks on and runs my natural gas furnace. I also have a New England Soapstone wood stove for back up. I had to live several months without reliable heat in south louisiana during the winter and swore I would never be without a reliable source of heat again. I can live without A/C but frick the cold.
There was a recent thread about what you rather do with out AC or Heat in South LA, the overwhelming response was heat, most said it was of no real value in South LA, and rarely turned it on. Good to see I am not the only one that would give up AC before heat even in S.LA!

Why not a single phase system like a 14 SEER Trane
The extra money for the heat pump is not worth it and they do have issues as well.
You can get a 3 Ton 14 SEER Trane for $4,500 with natural gas.
My electric bill in winter is $29-$45 for 3,900 sq ft home and gas bill is around $80.
These are Houston prices though as energy is deregulated so it's much cheaper than Louisiana.
The 14 SEER 3 ton Trane will probably cost around $5,000 in Louisiana so not too much more. They are cheaper in Houston and labor is too.

How do you manage to connect your blower motor and control board to your Honda EU2000 generator?

My blowers/air handler is plugged into a standard 20 amp outlet next to the unit in the attic, I run a extension cord from the generator through a attic window unplug the unit from the outlet and plug it into the cord. My Trane unit came with the power cord and plug installed so I would assume that this is the typical power connection for most gas furnaces.

So your air handler is 120 volt 20 amp unit???

Actually it is 120v at 5.2 amps, its a Trane unit with a 1/5 Hp blower motor, that and the ignitor/control circuitry are the only parts using electricity. From the Trane catalog it looks like the highest current draw of their gas furnaces is 10.2 amps, and that was their largest unit and it has a 1/2hp blower motor. I would think gas units by other manufacturers would be similar in their electrical requirements.

Guess I have always had electric heat strips in my air handlers and assumed they were all 240. But makes sense being that all you are running is a blower motor and some electronics.

electric furnace provides heat. I think the AC guy is trying to say the heat pump is not needed but would require less energy to heat the home. I'm so confused
Posted on 9/24/18 at 8:10 pm to Bayoufightingtiger
It is cheaper to run. If the temp gets too low for it to perform the heat strips come on. Been using heat pumps since I was a kid it’s a not an issue. I just changed by entire system including ducts. Put in a Lennox 4 ton 19 seer variable speed heat pump. Electricity bill went from $275 to $91. Not exactly apples to apples but it cut my cost at least $100 a month. Main thing I can tell you is 90% of the people that put in units have no idea what they are doing. They can hook it up and make it blow cold air. They have no clue how to get it to cool the house correctly

You can have an electric furnace (heat strips like an oversized toaster) or a heat pump (ac running backwards).
Heat pump is initially more expensive but heats cheaper than heat strips. If you like to run your heater a lot and keep your home nice and toasty, go with a heat pump.
If you only kick the heater on to get the chill out, go with heat strips.
On a side note, heat strips tend to dry out the air more.

I went with a 18 seer heat pump with 2-stage electric strips for heat and have been very satisfied with the unit and electric bill about 8 years ago. it will save you money I believe.

Gas heat is by far the most efficient and cheapest way to heat a home in south Louisiana. But if you don’t have gas, you must depend on electricity for your heat. Heat Pumps only come into play during the heating cycle and are all electric. The heat pump unit will only be able to heat your house to 40 degrees outdoor temperature. Then you will need to have auxiliary electric heat strips installed in your electric air handler to heat your home below 40 degrees. A high efficiency heat pump will be less expensive to heat your home vs only having to depend on the electric heat strips with no heat pump. As for as the air conditioning, there is really no benefit to having a heat pump.
