Mini splits AC only or Heating too?

Hello,
We have no central air and the summers are brutal. We can't find a window unit capable of cooling the entire first floor which is an open layout; so we decided to install a mini-slip air conditioner of 24,000 btu to solve the issue. Our bedrooms upstairs have window ACs. When consulting with the technician he suggested I install a mini slip that also offers heating. We do have central heating, so I don't understand what the benefit would be to have an additional heating unit just for the first floor. Can anyone advice or offer some insights? Should I spend the extra money to include heating as well? Will it save me any money or provide any extra comfort? Thanks!!!

Depends on several factors. Design of home, size, location

How do you heat now? Forced air or boiler? Ductwork system in place or none? What is fuel source? If straight electric resistance, propane, or fuel oil, then there may be some operating cost advantage to a HP mini split.

The extra cost for heating was very little on our installation so we added it even though we have in-floor radiant heating. It has come in useful a couple of times when a part on our heating system malfunctioned. It has given us breathing room to make repairs during the daytime when something malfunctions at night (which always seems to be the case).

The questions from tigerdunes are important to answer. The cost of adding heat might be small, but it does add some mechanical complexity. Reversal valves in heat pumps have been known to fail.

I have another question about your heat. Is it zoned? If not, you can heat just the downstairs. That said, heating just the downstairs tends to be difficult since hot air rises.
