Mis-matched split system components

Would you say anything about a Carrier gas furnace/air handler matched up with a Comfortmaker AC condenser?

This house had dual split systems.
2 Comfortmaker AC condensers.
1 Comfortmaker furnace
1 Carrier furnace

All the same age. House is < 10 years old.

Carrier and Comfortmaker are both owned by United Technologies if I remember correctly. I would not think there would be a major issue matching those components up.

Found this: “Carrier owns International Comfort Products and Bryant Heating and Cooling and is owned by United Technologies Corporation. Carrier is headquartered in the United States.”


Carrier also makes Payne

You can put any furnace on the A/C.
The condenser and evaporator must be matched. Furnace only need to blow the right amount of air. Most come with 3 spd blowers.

Not true with heat pump.
