Our air conditioner compressor failed at our old Minnesota after 21 years. The compressor failed at my mom’s old house in Minnesota after 17 years. I’d expect that the air conditioner would last much less time in Florida, because air conditioning is used a lot more in Florida.
We replaced both AC and the furnace in Minnesota with higher quality units. The furnace still worked, but had two failures which required emergency service in the middle of the winter, two years in a row.
We replaced the single stage AC with a two stage AC unit. The two stage AC alternates between cooling and dehumidification. It works better than single stage AC, and did a better job reducing the humidity level without making the air temperature too cold. The blower was a multi speed DC motor that had 200 speeds. Normally, the continuous running blower ran very slowly, and would occasionally ramp up in speed. That kept the temperature much more even, throughout the house.
I don’t know if a two stage heat pump exists. When one or both of our AC units fail in our Florida house, I’ll replace them with higher quality units.
Furnaces normally last 20 to 30 years in Minnesota. I assume that the furnace part of your HVAC system in Florida probably lasts forever, since it’s used pretty infrequently in Florida.
