Gas is on the rise. It was cheap, but here in PA, Peoples is going to the PUC to increase it 35 %.
If you use foam, that is a great insulator. But your respiratory system and health will suffer from years of VOC vapors. Plus the house will have no turnover of air Called new house syndrome or sick building syndrome. It is a big, big problem. Really big. Canadians know about this all too well. Your house I suspect wasn't insulated as well as you would think if it was a spec home or a home in a development. That's just what we see as HVAC contractors.
Most of the comments seem correct. Even though it's 72, the air may only be 92 and it is "moving" out of the vents at day 600Feet Per Minute. That is what feels colder.
Leave the thermostat in one position. Set it and forget it.
Moral is:: big house, big expenses. . oh and change that filter when your mortgage is due. Can't stress that enough.

In heating, winter, you try to overcome a 70 degree, 0 outside 70 inside, difference.
Hang in there boys.....Spring is right around the corner. Good thoughts.
It's mainly the builders. If gas isn't around, they go heat pump electric backup. Then the people buying the house just kinda suck it up.
I know I've had success with cutting a guys oil bill going hybrid. AC needs replacing, or installing, go heat pump set to changeover to oil at say, 35 outside. Last one I did the guy said he went from 2k per season in oil to 600 last year. And believe it or not, rural areas there is still a good bit of oil furnace out there.
That being said, mention heat pump, and it's not uncommon to see a guys eyes roll around here.
I need to re look at my insulation as well. There are some things the last owner did half assed. And I’m stuck cleaning up their mess. Structurally this place is sound and well built it’s the finish work they fucked off on. And it’s starting to piss me off. finding shit weekly. My old house was buttoned up and neat. Nothing was beat. Door jambs are fucked in this house. I need to replace the doors. Etc.
Had an old wooden deck that rotted. They ripped it out. Replaced with walmonized wood where it flushed up to the house and didn’t insulate. Found that out when I tore the carpet up and replaced some plywood and insulated. Then installed new floor. My bay window i crawled under the other day, I can tell they tore the bottom off with the deck Put up 1/2 inch foam board and racked up new plywood and said fuck it. I’m losing a lot of heat right there.
Dumbasses painted all this beautiful poplar baseboards white. Makes me sick. When I pulled some off it’s a great dark wood.
Replaced all door knobs in the house. They spray painted them black. Different color light switches. Some white. Some cream in the same receptacle. People really know how to fuck shit up.
Holes in all the walls. Like just pounded shit into the wall 5-6 nails wide until they found a stud. Covered it up. Like 100 Pin holes from a poster sticking teenager. Took me 8 hours with sheet rock 45 to fix room.
Sucks when you’re looking at a house you don’t really notice all the finish shit until you’re fixing it.
Naturally, they gave me a price to work with their "approved" contractor to fix all of this stuff, but I just took the report and started fixing things on my own. I won't say it solved all my issues, but it definitely got me going in the right direction.
If you only need 4 tons of cooling in the summer, a 5 ton system won't be comfortable, since it won't run long enough to dehumidify air. It will cool it fast, but not get the humidity out since the actual running time of the compressor will be less, so it won't remove as much humidity. In Arizona, that isn't a problem. Around here it is. That's why houses have 1.5 ton through 5 ton residential units, plus many times a separate unit for a house with two floors. There is more too it than that, but that gives you an idea what is going on in the AC mode. If you buy a 2 stage model, or an inverter system, then forget what I just said.
You also lived there during the summer, but your bills must of been OK. So really, you just need a higher efficiency Heat pump. Don't really concentrate on SEER, as HSPF is the more important number for winter use. HEATING SEASONAL PERFORMANCE FACTOR. Just know this: the higher the SEER or HSPF, the cheaper to operate. Equate SEER like MPG. The higher the number , the more efficient.
Best bet, and least expensive, is one of those Bryant or Mitsubishi mini split systems. Use it as supplemental heat when cold AND heat and cool your largest area! Man, the new Bryant (or carrier, same company with a different name) are 42 SEER, like 3 times ( Yours is 13 SEER) more efficient than your system now. I'm building a house at Club MX and I'm putting 4 of them (9,000 each) them through out the house. I figure my electric-bill for my 1500 SF house with a 3 car garage (also heated and cooled) will run about 90 bucks a month in the summer with a heat pump hot water heater.
Your Model Number on your HP is 4HP13L48P Refrigerant is R410 A, 13 Seer, 48,000 BTU ( 4 ton)

PM me something and I'll tell you what I would do. Those BOSCH Inverter driven Heat pumps ( conventional systems like yours) are very, very good replacement heat pumps. We sell a lot of them
Never shuts off. And the heat coil must always be burning red. that electric coil really sucks up the energy.

Just curious, what is your cost per kw/h?
right next to it, and no water heater. The square hole holding the gas burner would have been a cast iron door. You opened it, shoveled the coal in and poof. Heat.
I tell you 2stroke, that's a pretty current look at what is going on out there right now. That's a big house with 2 complete systems. Maybe upstairs and downstairs. Or, 2 apartments, or stores.
Someone just replaced both water heaters. Good job really, imo. Notice the small white expansion tank. Should be on there but a lot of times isn't.
Hard copper soldered in all the way to the tanks.
He could have went to plastic, used shark bite fittings that just slide on and not even had to get the torch off the truck. Much quicker:easier. A lot of that going on, you'd be surprised how many guys out there can't sweat copper.
Solar is a good investment now with most covering the initial cost within 5-9 years depending on installation costs.
Arguments for both sides.
I try and sweat em in, and I have resisted going the shark bite route. But it's more work. Need more stuff. Takes more time. And if you have a leak it's like, o foc, I gotta drain this thing, where is that garden hose . On the other hand all copper come on, it has to be better.
All I'm gonna say is I keep 2 sets of those SS braided hoses, 1/2 and 3/4, on the truck. The 2 foot long ones. That bolt right up to the tank and slip on the copper pipe.
