Looking for expert advice. Time to replace my HVAC.
This is for MY home, not a rental. 2900sf
Need to choose between gas and elec. After rebates and IRS tax credit the prices are within $200, so price difference is not a deciding factor. My reliable furnace man says the operating costs for each are about the same.
For elec, I'll have to upgrade my service panel, but I planned on doing that anyway.
I like the idea of getting away from the gas co because they make my life miserable with the rentals. I also like the idea of no carbon monoxide worries.
Gas: Tempstar 95%, 100K btu, 14 SEER 4 ton AC.
Elec: Tempstar 15 SEER, 4 ton heat pump (man those things are HUGE!! but I have the space)
Any suggestions or preferences? --69.243.xxx.xx

Kinda depends on whether your area (climate) is well suited to a heatpump. Here in the deep south, they are the bee's knees. I would not dream of using gas. However, in colder climates you may prefer the much faster and warmer heat from fossil fuel.
This is a LOCAL question, so you need to ask it of locals. Get 3 HVAC guys to tell you what they think. Look around and see who has converted from gas to a HP, ask em how they like it. --141.129.x.xx

I would go with gas for my home. Elec will cost more to run in the future as president TelePrompTer wants to do away with coal fired plants. A good co2 detector. Can be purchased for less than $40. Plus this is not a rental, and you will take care of the unit, and not abuse it like a tenant would --173.74.xx.xx

Air sourced heat pumps are not as efficient as a ground sourced heat pump as the extreme temperatures in the summer and winter degrade the performance. A ground sourced heat pump is very expensive to install but very economical to operate all year round. Generally ground sourced heat pumps are not used where natural gas is available as it always cheaper to install a high efficiency gas furnace or boiler. Now is the time to look at upgrading insulation and windows which will significantly lower the overall energy consumption along with less and tear on the heating equipment. --74.220.xxx.xxx

Geothermal. I have a totally electric home, 2,200 sq. ft. and my highest electric bill was under $150. --205.188.xxx.x

I'd check closely on difference between gas and electric rates . Here Electric is at least 33% higher than than Gas. --70.248.xxx.xxx

Agree with Rich (IN). I have geothermal and love it for heat and a/c. Can almost hang meat in the house in the summer. --71.49.xxx.xxx

Why not separate the heating from the cooling? Have you looked into insulating your house better, then buying a unit 2 sizes smaller? Top notch windows with metal coating to reflect the heat or cold?
I would NOT want to heat with electricity.
There are clever venting systems recouping the heat or cold as needed. Spend 20 grand more, then save a few grand on the system and every year. --125.25.xx.xxx

If you are willing to spend the money, geothermal is the way to go. You can get a 30 percent rebate of the total cost, no cap. With any other system there is a $1500 cap. --74.222.xxx.xxx

I do live in an area where a heat pump is appropriate. I still prefer gas heat. Don't care what it costs to run the thing (although the cost is comparable now) - I just prefer to have HOT air blow out the vents when the heat kicks on. Heat pump blows air that doesn't feel hot, even though it certainly does warm the house; it just takes longer. --216.79.xx.xx

Here's something to consider: a "hybrid system". We had a propane (no gas locally) furnace quit on us, and the air conditioner unit was old and woefully inefficient. Rather than buy a new propane furnace and a new a/c unit, we got the furnace and a heat pump. They are linked by a "smart" thermostat. A sensor is installed on the north side of the house. When temps are above 34 degrees, the heat pump provides the heat. Below that, the furnace runs.
The beauty of the system is that:
-it only cost us about $300 more for the heat pump over the a/c unit,
-if electric shoots up too high, we can override the system and solely use the propane furnace.
I'm sure that gas/heat pump hybrid systems exist, just be sure that you get an experienced installer, as the thermostat wiring is a little tricky. BTW, we're using a Trane system, and are coming up on 4 years with the only problem being that some tree branches dropped and we had to relocate our outside temp sensor, due to late afternoon sunlight throwing it off. --71.185.xxx.x

I know of two guys locally who use that "hybrid" system, I'm sure there are more.
You can use either a Honeywell IAQ smartstat or an add on relay and outdoor thermostat to overcome the issues. I prefer this relay: www.theheatpumpmadeeasy.com --141.129.x.xx

I follow Wilma idea, it makes sense to use gas for e-heat, some places had the heat pump and can add the gas heat rather than run the meter like a frisbee. --66.72.xxx.xxx

Thanks! Expanding my search to geothermal. Found a system that pumps water in and out of 2 18' deep wells (water is 8' below my basement, sandy/gravel soil). No deep pipes nor large yard zigzag needed.
My super-engineer friend installed one, changing from a 25 year old elec heat pump. From that system he gained a true 25% cost savings on his total elec bill.
Locally, elec and gas furnaces cost about the same to operate. --69.243.xxx.xx
