UR thoughts on HP or Condensing for No VA

Hi Folks - need to replace the HVAC for a townhouse in northern VA. ~ 2200 sf, end unit with outside wall getting the afternoon sun, and the temp difference on the 3rd floor being as much as 8 degrees higher than the second floor in late afternoon of summer months. Current system is a 2.5 ton York builders' special from 1996.

Been reading the forum and am wondering if I should look at a heat pump configuration or stick with an condensing unit outside. I am receiving bids that are only condensing units with Trane and Carrier. My current thinking is to go with a Carrier Comfort 24ACC6 model and a Carrier infinity gas 80 58CVA090 2 stg, variable speed furnace, a power humidifier, and a Honeywell 4" media filter.

- Should I look at a heat pump configuration? Expected cost difference? Pros vs a condensing unit?

- What thermostat should I use to take advantage of the furnace and humidifier capabilities?

- Footprint space outside is a consideration for the outside unit. Are the Carrier Performance Compact series units worth considering?

Appreciate your insights - even if it is to tell me I'm being dumb :-)

I"m a fan of heatpumps over the straight A/C. They shouldn't cost much more over straight A/C. Maybe $500. They provide a steady stream of warm (not hot air). They run longer but keep rooms evenly heated. They do very well when above 30 F. Ofcourse it depends on how much your electricity costs. In a climate like yours heatpumps can run alot of the time and the gas only used say below 30 or 35 or 40 (depending on your comfort preference).

Heatpumps typically are built better than regular A/C's since they run much more.

Before you commit to anything, It would be beneficial to have your duct system carefully evaluated by an expert. You may be a candidate for zoning to cure your 3rd floor problems.

How was it heating that floor?
